With the plugins I've tested, if you install it as root it is installed globally - otherwise it is installed just for the one user. I can't read Norwegian, but poking around the www.firefox.no website it looks like they have an IRC channel & maybe a mailing list.

We CAVEAT: I'm not a teacher, I don't frequent the lists given below to know about them, and they are opensource-specific rather than LTSP-specific, however [...] You might take a look at a few sites that spring to mind having mailing lists that may serve your purpose. There are list archives to check out at http://archives.seul.org/ - the parent site can be deduced from that URL (oh hell, I'll give it anyway, it's www.seul.org). Another relevant site could be either/both http://opensourceschools.org/ and/or http://www.schoolforge.net/ The former leads you to the latter, but both appear to have something different to offer. The Schoolforge archives are at http://archives.seul.org/schoolforge/discuss/ Ooops! there we are back at seul.org again?! I don't know if they are just hosting schoolforge or if it's a fork of the original site. Anyway, worth a look at those few. Report back to this group if you find them useful or otherwise, please. -- Regards, Gavin Chester From tlegge at rogers.com Wed Dec 1 01:50:52 2004 From: tlegge at rogers.com (Timothy Legge) Date: Tue, 30 Nov 2004 21:50:52 -0400 Subject: [K12OSN] Menu issues in mozilla/firefox with wheel mouse In-Reply-To: <1101855022.2953.11.camel@athlon.johnsonavenue.org> References: <1101855022.2953.11.camel@athlon.johnsonavenue.org> Message-ID: <1101865851.2953.15.camel@athlon.johnsonavenue.org> On Tue, 2004-11-30 at 18:50, Timothy Legge wrote: > I just installed a new K12LTSP server based on 4.1.1 and I seem to be > having problems with my wheel mouse. > > The wheel works fine scrolling down the page but when scrolling up the > page I get the right click menu.

After a lot of time reading up on NFS, looking through configuration files and kernel settings, and reading the kernel mailing list archive, the iopeners are booting again. The solution was to nfs mount /opt/ltsp/i386 over tcp/ip rather than using the default udp. This mounting parameter is in the linuxrc of the initrd for the client kernel. (The rsize and wsize values are set there also, but it wasn't necessary to change them from the defaults.) The implementation of nfs in the 2.6.x kernel used in FC3 results in timeouts and hanging under network conditions that were not a problem with the 2.4 kernel. Swapping out the usb network adapter for something faster was not possible but a decent nic is clearly the optimal solution. With the iopener a usb nic is as good as it gets!

One of the options is to NOT have a user password. Otherwise you'll have to use "useradd" or "adduser" command and then use the "System Setting" -> "Users & Groups" -> select the user(s) and manually unlock each account. You can also manually create the account and then delete the password field in the "/etc/shadow" file good luck norbert From eric at bluecranecs.com Wed Dec 1 03:04:36 2004 From: eric at bluecranecs.com (J Eric Smith) Date: Tue, 30 Nov 2004 22:04:36 -0500 Subject: [K12OSN] Re: K12OSN Digest, Vol 9, Issue 142 In-Reply-To: <20041201014717.AC4B87449A@hormel.redhat.com> References: <20041201014717.AC4B87449A@hormel.redhat.com> Message-ID: <41AD34C4.3090600@bluecranecs.com> > > >Ok, I'm going to go out on a limb here because this thing is dragging on >too much.

However, the burns are still not bootable even when I'm burning fresh, checksum'd .iso's in Ubuntu with Nautilus's built-in ISO burning mechanism. Burns of Knoppix, Mepix, and a half-dozen other distros boot fine, whether I burn them in XP2 or Linux. I'm not sure if it's the iso's or my system. As I've managed to get around this by using the boot.iso to do a network install, it hasn't been a big deal to me. Btw, very happy that B5 fixes the dependency issues.

I never have boot problem from K12LTSP beta2, beta4 and beta5. I do not consider using Windows XP at all. What I use is mainly Linux and Windows 2000 with SP4. As many people have boot problem, I use X-CD-roast in Linux to re-create the iso files from the burned CDs (discs 1 and 2) of beta5. I then check the md5sums of my created iso files. I get the same md5sums as the those from K12LTSP. Therefore, I am sure my burned CD is free of any error. If there is still boot problem, we can try to burn the CDs in different OSs, eg. both Linux and Windows systems. Then we can compare the result.

They get an ip address and then hang "doing the pivot_root." tail -f /var/log/messages shows that dhcp passes the address (192.168.0.6) , the mount request for /opt/ltsp/i386 is authenticated .....and that's as far as it gets. > > > > > > tcpdump shows that packets are being fragemented and "ip reassembly time exceeded." The output of "tcpdump -i eth0 | grep ws006.ltsp" is below. This happens with the 2.4.21 kernel and another earlier kernel without nfs-swap both of which worked well with earlier versions of ltsp. > > > > > > I played around with hardware (different cat5 cables, different ports on the switch etc.) and replaced the nfs-utils and system-config-nfs rpms with earlier versions but the problem remains. Does the nfs daemon that comes with fc3 run over tcp/ip? Where are the rsize and wsize values of the exported /opt/ltsp/i386 set? I grepped and found the mount parameters for the swapfiles in rc.sysinit but I cannot track them for the root directory.

The solution was to nfs mount /opt/ltsp/i386 over tcp/ip rather than using the default udp. This mounting parameter is in the linuxrc of the initrd for the client kernel. (The rsize and wsize values are set there also, but it wasn't necessary to change them from the defaults.) > > > > The implementation of nfs in the 2.6.x kernel used in FC3 results in timeouts and hanging under network conditions that were not a problem with the 2.4 kernel. Swapping out the usb network adapter for something faster was not possible but a decent nic is clearly the optimal solution.

Forgive my rambling question in response to this thread: Solutions offered on this thread, that has been repeated several times in the context of power-saving and screensavers, is to disable power-saving in the thin client bios. Not having ventured down this path myself, is there any way to continue to allow power saving on the client so that it just wakes up when someone sits down to logon? The goal of saving electricity seems less important to many LTSP setups than it is to environmentalists like me. Or, do I have that wrong too ;-) ? -- Regards, Gavin Chester From penguintiz at yahoo.com Wed Dec 1 14:42:40 2004 From: penguintiz at yahoo.com (David Tisdell) Date: Wed, 1 Dec 2004 06:42:40 -0800 (PST) Subject: [K12OSN] Re: Data Collection and analysis In-Reply-To: <20041201014717.C40077449B@hormel.redhat.com> Message-ID: <20041201144240.20736.qmail@web41902.mail.yahoo.com> Frank, Thnks for the info!

I am having a bit of trouble setting up sound on my workstations. I am using Version 4.0 of K12LTSP. I did make sure that sound is set to "Y" in lts.conf. I left SOUND_DAEMON as nasd. Also left the default volume at 75. When I try to configure the sound card, it picks up the sound card on the server. I attempt to play the test sound and I cannot hear the sound on the workstation.

Michael, I have been hoping someone would explain nasd for a while, I just don't understand what it is or does. I have sound working with esd as the sound daemon, but not with flash sites (no sound in flash) If you use "esd" instead of "nasd" -- and then reboot the thin client, try (in an xterm) typing "esdplay soundfile.wav" and see if you get the sound to play. If so, then you have working sound, and can configure any application that supports esd to use it. Thunderbird email seems to just magically work without configuring for esd specifically. Mplayer (video player, awesome, worth the compile) works if set to use esd, xmms works if set to use esd (or esound, it's the same thing esd=esound), etc, etc. If you get any other info, I'm very interested as well. -Shawn -- Shawn Powers Technology Director Inland Lakes Schools PHN: 231-238-6868 x9174 FAX: 509-356-7024 spowers at inlandlakes.org http://techcorner.inlandlakes.org ---- The views, opinions, visions, thoughts, comments, sarcastic whims, forecasts, poetic outbursts, cynical wit, future plans, implementation ideas, OS preference, curricular insight, ice cream preference, or anything else I might infer are not the views of Inland Lakes Schools.

How about we add a section in the wiki to try and centralize things? OK, I admit it, I am doing that now. I have added a section under "Software" called "WorkstationSound". Hopefully, we can centralize the knowledge about sound there. I've included the information from this thread into the wiki, without credit. So far, I have to admit, I haven't tried too hard myself, and my system doesn't do sound under KDE anyway. I'm not an authority. It would be nice to find some authoritative information in the Wiki. http://www.k12ltsp.org/phpwiki/index.php/WorkstationSound Angus Carr.

I'm already working on packaging it ;-) I'm thinking that a cron job that checks for /tmp/.esd/socket and creates it if it does not exist would be the least hackish approach.

However we use OSX servers here for our student file servers. They are not on our domain, but they server both apple share as well as windows shares. Is there a way to connect to these servers via linux? I'd like to be able to put an icon/link to the server on each client desktop to make connecting a bit easier as well.

A lot of the juice to run a thin client (say, a Pentium-166) would normally go toward spinning the hard disk and keeping the monitor lit up. Since we unplug the HD's, that power is never used in the first place. :-) Pentium-166 and even 233 CPU's don't really use up that much juice...not like a Pentium-III, Athlon, or especially Pentium 4! So, yes, you do get your "environmentalist" power savings with thin clients. Plus, if you use "old" Pentiums and such, you're keeping them out of the landfill for much longer than you would otherwise. --TP _____________________ Do you GNU!?

I made a confusing statement, I'm sorry, because I intended to mean power saving for the monitor of the client - not the CPU & hard disk of client. Is there an effective means to implement monitor "sleeping" that doesn't cause problems that some others have written about (as in the original posting)? -- Regards, Gavin Chester From sales at ecosolutions.com.au Thu Dec 2 05:25:48 2004 From: sales at ecosolutions.com.au (Gavin Chester) Date: 02 Dec 2004 13:25:48 +0800 Subject: [K12OSN] alternative power supply Message-ID: <1101965151.1069.199.camel@compaq.mydomain> In a related thread we were discussing power saving on the client monitor.

I've got my home directories on a second drive. I need all requests for home dir to go through the main LTSP server which is where the second hard-drive is mounted with all of the user directories. I've read the wiki, which is painfully shallow on setting up multiple LTSP servers on the same network, http://www.k12ltsp.org/phpwiki/index.php/FullTextSearch?s=multiple+servers and it is rarely updated and has only rare bits on real-world setups. I need to add a second server to relieve some of the load on the main server. I searched for sharing load on the wiki and it came up with no hits: http://www.k12ltsp.org/phpwiki/index.php/FullTextSearch?s=sharing+load I have no cash. I can't buy more RAM. I put the network together on donations of computers and the generous help of a helpful LUG member. I need to add a second server without losing home dir. access. I'm thinking some kind of authentication either NIS or LDAP but, after having copied the home dir to a second HD my students __are__ able to log in. Their folders/ files etc. are gone, they __can__ log in, but all of their previously created documents/prefs/ history files are missing so naturally I'm more than worried that adding a second server reffing the /home dir on the second drive on the primary ltsp server is going to really mess things up. I've got a number of scripts that are working on students' files now so I'm loathe to mess around yet further with home dir. paths. I want the main server.ltsp.one on dhcp response on 100-120. server.ltsp.two dhcp response on 121-130 but the authentication of having the /home dirs is causing me no end of anguish. Accessing the home directories via NFS failed flatout. NFS would not play nice on k12ltsp 4.1/FC2 even for a seasoned linux buddy of mine. Make no mistake, I love what I've got working now. But, the network is slow and my student's protests are growing louder for paper and pen. I need a cheap 'dummy' solution for my problems here; I'm not a computer science major. I'm only a dedicated teacher trying to put the 21st century in front of my students but I feel like the 21st century is going to beat us because it is __too__ difficult and __too__ complex for the ordinary mortal to set up a network that requires more than one moderately priced LTSP server to support the user load. We only use firefox and gedit. OpenOffice users are booted off immediately. Tuxtype is the same. Anything more than the most basic webbrowsing and text editing is immediately questioned. Application cop is not the role I want to play as an English teacher in an LTSP enabled classroom. There has got to be an easy way to add more server power to an existing network without digging deep into moth riddled pockets. I am a poor teacher, not a rich school district. Is there anything in the works (next version of LTSP?) that makes it __easier__ to add a second, even third server, to existing networks without increasing user authentication problems/home directory issues? I ask because I know that Mandrake will ask you where the home dir will be located...and having read that Skolelinux has an authentication/multiple server configuration already built in(?). Is there anything in the LTSP that will ask how many servers the admin wants to set up to support the LTSP network? I use webmin but there isn't thing nice in there that says, "Ah, your using LTSP... I see another LTSP server offering DHCP. Would you like to have the second server reference your existing home directories?" I've got a dual xeon 2.4ghz, two gigs of RAM. ltsp.server.one I've got a second dual PIII ltsp.server.two with two gigs of RAM as well. I can't shell out more cash. The school district Computer Informatin Services head guy wouldn't mind seeing my 'little experiment' fail so that he can push through his Citrix/Microsoft client solution. My LTSP proof of concept is on the edge of failing. I'm not a trained/certificated sys admin. I'm an English teacher. And I find myself asking more and more, "Is K12LTSP only for small boutique/wealthy classes/teachers if you're not a full-fledged and trained sys-admin or have deep pockets?" I need to squeeze more performance out of my single server(now) 35+ node network before parents/ stakeholders step in and say, "Enough, you failed." Is there anyone in the Los Angeles region who has a multiple LTSP servers on the same network running? Can I come and see how you've got your network setup? I'm nearing desperation here. Maybe a competition describing the most performance out of the cheapest setups of LTSP? Anything! I can't get any interest in LTSP out of other teachers or the administrators when they see/hear how much trouble I'm having. I'm not stupid but there are some critical pieces missing in the documentation and narratives on how to get more out of LTSP network on a real classroom size of 35 plus students without spending thousands of dollars on new servers and clients. ---------------------- Could someone please do a write up on how they set up multiple LTSP servers on the same network to share the load? Please include more details on how you set up the central home directories and the authentication of the user logins. Many many thanks to all of those who have made the LTSP applications as powerful as it is now! I beg of you to make it easier to add tools to make it easier for the dummies, like me, who see the future in computing in the classroom, but don't have the same years of experience! Please! I want to be able to say that K12LTSP is ready for prime time in the classroom! many heart-felt thanks!

If you mount an existing /home into /home on a new server, the only requirement should be that the user/group id numbers are the same for each login on both machines. If you use LDAP or NIS, this will happen automatically across machines. If you don't, you have to make sure that the contents of /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow stay in sync between machines. > Make no mistake, I love what I've got working now.

If the network is the problem instead of your CPU speed you should use a different NIC on the servers for the NFS traffic. > I am a poor teacher, not a rich school district.

Someone mentioned here that you can use one machine running Skolelinux as the authentication and home directory server to take advantage of the canned LDAP setup, configuring the k12ltsp's to use it. But, if your servers are identical you can just copy the passwd/group files after any changes. > Is there anything in the LTSP that will ask how many servers the admin > wants to set up to support the LTSP network?

Would you like to have the second > server reference your existing home directories?" One NFS mount in your /etc/fstab should be all it takes to make the home directories appear where you want them. Webmin does have a cluster mangement option to add the same users across machines if you don't use LDAP/NIS but I haven't used it. > I need to squeeze more performance out of my single server(now) 35+ node > network before parents/ stakeholders step in and say, "Enough, you failed."

The power supply doesn't automatically produce that much power--something has to draw that power from it. Additionally, that maximum power rating is usually divided up among multiple power outlets which you plug into your hard drives, cdroms, etc. For simplicity's sake, lets assume that you have a 400W power supply with 10 power leads coming off of it. Each power lead would be capable of providing 40W. If you unplug 9 of the power leads (no hard drive, no cdrom, etc.) and only leave the motherboard plugged in, your power supply will now only produce a maximum of 40W, simply because there is nothing else to draw the power. Generally, there are efficiencies to be gained by sizing power supplies close to the real power requirements. So using a 400W power supply to produce only 40W will probably waste more electricity than using a 100W power supply to produce 40W. I'm speaking in generalities here, and I don't know if this will make a big difference in the case of thin clients or not. The best thing to do would be to actually measure the power consumption. You could do it on the input side and you wouldn't have to open the case. Or you could measure it on all the outputs, but then you wouldn't be accounting for wasted power in the form of heat produced by the power supply. Measure it and see if you think it's excessive and if it's worth your time to try to reduce the power consumption. -Rob --- On Thu 12/02, Gavin Chester < sales at ecosolutions.com.au > wrote: From: Gavin Chester [mailto: sales at ecosolutions.com.au] To: k12osn at redhat.com Date: 02 Dec 2004 13:25:48 +0800 Subject: [K12OSN] alternative power supply In a related thread we were discussing power saving on the client

To quickly turn in on, run "service nfs start". Make sure you have "server.ltsp.two" defined in /etc/hosts... otherwise your system won't know what IP address belongs to server.ltsp.two. Now on your 2nd server, you can run "mount server.ltsp.one:/home /home" which mounts the /home directory on server.ltsp.one on the local directory "/home". Make sure again, you have the IP address of server.ltsp.one defined in /etc/hosts.... NFS should work.

2. How do you connect to a Mac OSX server from a LTSP client? The OSX

Any help here would be appreciated.

Message-ID: <41AEB897.3090200 at magic.fr> Content-Type: text/plain; charset=us-ascii; format=flowed Greetings all from a harried teacher a.k.a. sys. admin, I'm at wits end here. I've got my home directories on a second drive. I need all requests for home dir to go through the main LTSP server which is where the second hard-drive is mounted with all of the user directories. I've read the wiki, which is painfully shallow on setting up multiple LTSP servers on the same network, http://www.k12ltsp.org/phpwiki/index.php/FullTextSearch?s=multiple+servers and it is rarely updated and has only rare bits on real-world setups. I need to add a second server to relieve some of the load on the main server. I searched for sharing load on the wiki and it came up with no hits: http://www.k12ltsp.org/phpwiki/index.php/FullTextSearch?s=sharing+load I have no cash. I can't buy more RAM. I put the network together on donations of computers and the generous help of a helpful LUG member. I need to add a second server without losing home dir. access. I'm thinking some kind of authentication either NIS or LDAP but, after having copied the home dir to a second HD my students __are__ able to log in. Their folders/ files etc. are gone, they __can__ log in, but all of their previously created documents/prefs/ history files are missing so naturally I'm more than worried that adding a second server reffing the /home dir on the second drive on the primary ltsp server is going to really mess things up. I've got a number of scripts that are working on students' files now so I'm loathe to mess around yet further with home dir. paths. I want the main server.ltsp.one on dhcp response on 100-120. server.ltsp.two dhcp response on 121-130 but the authentication of having the /home dirs is causing me no end of anguish. Accessing the home directories via NFS failed flatout. NFS would not play nice on k12ltsp 4.1/FC2 even for a seasoned linux buddy of mine. Make no mistake, I love what I've got working now. But, the network is slow and my student's protests are growing louder for paper and pen. I need a cheap 'dummy' solution for my problems here; I'm not a computer science major. I'm only a dedicated teacher trying to put the 21st century in front of my students but I feel like the 21st century is going to beat us because it is __too__ difficult and __too__ complex for the ordinary mortal to set up a network that requires more than one moderately priced LTSP server to support the user load. We only use firefox and gedit. OpenOffice users are booted off immediately. Tuxtype is the same. Anything more than the most basic webbrowsing and text editing is immediately questioned. Application cop is not the role I want to play as an English teacher in an LTSP enabled classroom. There has got to be an easy way to add more server power to an existing network without digging deep into moth riddled pockets. I am a poor teacher, not a rich school district. Is there anything in the works (next version of LTSP?) that makes it __easier__ to add a second, even third server, to existing networks without increasing user authentication problems/home directory issues? I ask because I know that Mandrake will ask you where the home dir will be located...and having read that Skolelinux has an authentication/multiple server configuration already built in(?). Is there anything in the LTSP that will ask how many servers the admin wants to set up to support the LTSP network? I use webmin but there isn't thing nice in there that says, "Ah, your using LTSP... I see another LTSP server offering DHCP. Would you like to have the second server reference your existing home directories?" I've got a dual xeon 2.4ghz, two gigs of RAM. ltsp.server.one I've got a second dual PIII ltsp.server.two with two gigs of RAM as well. I can't shell out more cash. The school district Computer Informatin Services head guy wouldn't mind seeing my 'little experiment' fail so that he can push through his Citrix/Microsoft client solution. My LTSP proof of concept is on the edge of failing. I'm not a trained/certificated sys admin. I'm an English teacher. And I find myself asking more and more, "Is K12LTSP only for small boutique/wealthy classes/teachers if you're not a full-fledged and trained sys-admin or have deep pockets?" I need to squeeze more performance out of my single server(now) 35+ node network before parents/ stakeholders step in and say, "Enough, you failed." Is there anyone in the Los Angeles region who has a multiple LTSP servers on the same network running? Can I come and see how you've got your network setup? I'm nearing desperation here. Maybe a competition describing the most performance out of the cheapest setups of LTSP? Anything! I can't get any interest in LTSP out of other teachers or the administrators when they see/hear how much trouble I'm having. I'm not stupid but there are some critical pieces missing in the documentation and narratives on how to get more out of LTSP network on a real classroom size of 35 plus students without spending thousands of dollars on new servers and clients. ---------------------- Could someone please do a write up on how they set up multiple LTSP servers on the same network to share the load? Please include more details on how you set up the central home directories and the authentication of the user logins. Many many thanks to all of those who have made the LTSP applications as powerful as it is now! I beg of you to make it easier to add tools to make it easier for the dummies, like me, who see the future in computing in the classroom, but don't have the same years of experience! Please! I want to be able to say that K12LTSP is ready for prime time in the classroom! many heart-felt thanks! Dennis Daniels __________________________________ Do you Yahoo!?

I have this happening too -- but *sometimes* they just don't wake up.
Strangely, it seems that just the monitor shuts off, but sometimes they
just don't wake up.

I want to know if there is a way to extend that time, because mine seem
to do it after 5 minutes, and USB Mouse movements don't count as being
"active" so if a staff member is surfing the web with just a mouse, they
get blank-screened in the middle of surfing.

The biggest problem, however, is that one of my thin clients is supposed
to be scrolling the bulletin via openoffice all day, and I don't know
how to get it to stop blanking.

Does anyone know how the X blanking stuff works? I tried setting "xset
s off" but it seems not to make a difference.

(Sorry Jennifer, I didnt' answer your questi! on at all, but rather posed
more!)

Dear Sez, This is guessing, but I think it should work. Find the directory where the default bookmarks.html file for Mozilla is and replace it with one of your creation. (make sure the permissions are the same after replacing as they were on the original) For example, on my old K12LTSP 3.12 server the file is at /usr/lib/mozilla-1.2.1/defaults/profile/bookmarks.html > 2. How do you connect to a Mac OSX server from a LTSP client? The OSX > server is serving appleshare as well as windows clients. > > Any help here would be appreciated. I'm not going to be able to answer this one very well, but I'll ask for some clarification. Do you mean automagically connect when a user logs in to their home directory, or once logged in how can a user get to their stuff on the OSX server 'by hand'? A few different ways via the command line would include ftp, ssh, and scp. For GUI, I think in Gnome they could use the network browser to connect to the samba shares on the OSX server (or via AFP if you have netatalk installed on your LTSP server) . The automagically stuff can probably be done using LDAP if you have that running on the OSX server and the LTSP server, but I have no idea how to do that.

To quickly turn in on, run "service nfs start".

Sorry -- yes the first. If I have one brand, I use it on the one port I have available, then take it out and put it in my pocket -- only to get another drive (different brand) and put it into the same port that worked a minute ago, it does not work.

Anyone know? > --Peter Peter, You can measure power easily with a clamp around type amp meter. It basically has a magnetic clamp that you clamp around a power wire and it gives a current readout. Multiply this by 120 (volt) to get power. The nice thing is you don't need to touch any high voltage wire. You will need to clamp only 1 wire (hot or return) but you can easily build a short extension cord with wires split, or carefully split the outer insulation on an existing extension cord and seperate the wires (think disecting an earthworm in science class).

We are in a financially challenged situation. We can get many older PII's for free and are using these as thin clients. Barring a lottery win, this is our strategy. Thus my interest in lowering power consumption as much as possible. However, if I can prove that low power LCD monitors and thin clients are worth purchasing (for their long term power cost savings), that would be great too. I need a way to figure out exactly how much our thin clients are costing us in terms of electricity. --Peter From spowers at inlandlakes.org Thu Dec 2 19:34:46 2004 From: spowers at inlandlakes.org (Shawn Powers) Date: Thu, 02 Dec 2004 14:34:46 -0500 Subject: [K12OSN] USB Drive Info In-Reply-To: <41AF6A09.6080504@paasda.org> References: <41AF62D6.4000208@inlandlakes.org> <41AF6650.5070600@paasda.org> <41AF6646.1000703@inlandlakes.org> <41AF6A09.6080504@paasda.org> Message-ID: <41AF6E56.70806@inlandlakes.org> Huck wrote: > the odd this is that a 'relog' of the user did not help...the entire > unit had to reboot (correct for you too) ? Yeah -- same scenario. I did just have my tech assistant try 2 usb drives of the same brand, and they did both work. Differnet brands though require a complete reboot of the thin client. (Even going to the console of the thin client and killing off floppyd and restarting doesn't do the trick, not that that would be a feasible solution, but I tried it anyway) That just gave me a thought -- is it possible to have usb drives AND local floppies working? Does the floppyd daemon support multiple devices? If no one knows, I can do some testing -- but I was just curious if anyone had tried it. -Shawn -- Shawn Powers Technology Director Inland Lakes Schools PHN: 231-238-6868 x9174 FAX: 509-356-7024 spowers at inlandlakes.org http://techcorner.inlandlakes.org ---- The views, opinions, visions, thoughts, comments, sarcastic whims, forecasts, poetic outbursts, cynical wit, future plans, implementation ideas, OS preference, curricular insight, ice cream preference, or anything else I might infer are not the views of Inland Lakes Schools.

Peter, Tom, Michael's co-worker at McKinley, would be more than thrilled to loan you his equipment (if needed) and give you the knowledge to accomplish this. He loves to break out that ring thing and measure currents. Your metrics could be very informative to every one, and the kids could spreadsheet it. I would also wonder if WYSE, HP, or Sun have their own marketing metrics promoting their energy savings over PC's. --scott -- R.

It does seem that Red Hat would continue to support the community by simply adding a new mailman list. (k12osn-educators) The overhead is inconsequential. What I wonder is, who started this "party" and can they request that Red Hat start another?

This morning as I was teaching a lesson the server let out a weird, mechanical noise albiet only for a few seconds. I was not concerned about the lack of redundancy in the data, but now I am. It was probably nothing, but My academic questions about the best configuration suddenly seem more practical. I gather that many of you have a problem with the Promise raid controllers. I also see that alot seem to favour the 3ware controllers. I feel I need to get a solution in place soon, probably over the Christmas holidays. So, in a nutshell: anything wrong with 4 - 80 GB 7200rpm EIDE drives with 8Mb cache running on a raid controller(as yet to be determined) in a configuration like 1 + 0 or 0 + 1? This gets me effectively 80GB capacity and redundancy with the ability to withstand 2 drives dying, right? this would get me, correct me if I am wrong, both redundancy and some performance increase, yes? old drives, with no redundancy, are old smallscsi drives of 5400 rpm speed on old controller From pvdw at criticalcontrol.com Thu Dec 2 20:54:15 2004 From: pvdw at criticalcontrol.com (Pete) Date: Thu, 02 Dec 2004 13:54:15 -0700 Subject: [K12OSN] best way to upgrade to FC3??

This is not a step by step obviously, if you need more explicit instructions let me know. Paul Thats an excellent idea, but i will check out with du what i will gain from moving /var before doing this. As a side note, i just found that Partition magic Version 8 will resize ext2 and 3.

So far the teachers are pretty much open-mouthed when I give them their orientation especially when I tell them the price. :) Now we are looking to have an official recycling drive because we don't have nearly enough terminals. I'm looking for some examples of copy of advertisements for such an initiative. I'm afraid I might not be able to write it without getting too technical. Maybe I'm a lazy writer but I'm a little worried I might not be making sense to the average person. I spend so much time in a technical world that I'm not sure how I'm being understood outside of it. I often feel that people smile and nod when I'm explaining how it works. Does anyone have examples of add copy like this? Thanks so much! Peter P.S.

It is easy at the site, too. Get one of those short grounded 3 wire extension cords that is *flat* where you can see all three wires with grooves between them. Carefully split off one of the three wires and don't cut the insulation, just split it out there. Then use a clamp-on ammeter to measure the current and do the math and it will tell you the watts. This will work for *any* device you plug into that short cord. Printers, monitors, computers, etc. If you want to measure the current to a whole set, like CPU, Monitor and Printer, just plug them all into a strip and plug the strip into the short cord and measure away. The math is: Power Watts over ------- Volts X Amps So if your measurement is 2A and the voltage is 120V, then the power (watts) is 240 (2A times 120V). If you measure .5A then your watts is 60 (.5 times 120) I measure things like this at home all the time. You would be surprised just how many watts some things use! And watts is what you pay for!

With most cheap IDE controllers you are better off running Linux software raid than the controller version which is mostly software anyway. You really want to keep each drive on it's own controller so you'll need some kind of extra card to handle 4 drives. Note that you can't lose any two drives at once - you are only covered if you lose one of the drives with a still-working mirror. > this would get me, correct me if I am wrong, both redundancy and some > performance increase, yes? Doing raid0 may give a performance increase, raid1 gives redundancy. You can do either or both. Doing 2 separate raid1 mirrors would mean that you could recover the data from any single drive if you plug it into another machine. That is difficult or impossible with other raid schemes but if you have some other backup may not matter to you. --- Les Mikesell les at futuresource.com From penguintiz at yahoo.com Thu Dec 2 22:03:04 2004 From: penguintiz at yahoo.com (David Tisdell) Date: Thu, 2 Dec 2004 14:03:04 -0800 (PST) Subject: [K12OSN] Connect to OSX Server?

Unless something had changed very recently, Netatalk only functions as a server not a client. You can connect Mac Clients to Linux servers via netatalk but not Linux clients to Mac servers via netatalk. Your best bet is to either use Samba or NFS. Setting up an NFS share on an OS X server is relatively simple to do. Alternatively, you could use Samba. I believe there is a PAM module for samba so that all of the account info would come from your OS X server and their home directories would automount. I have done this with Netware and ncpfs with help from people on theis list. If you can do it with Netware and ncpfs, you should be able to do it with Samaba as that is far more widely used and better documented. Dave __________________________________ Do you Yahoo!?

Then 3 drives go in, one as master1, master2, master3 -- and voila! Cheapest raid5 w/hotspare I know how to get ahold of. Essentially you want to make sure they have their own CHANNEL, not necessarily their own controller. As long as one is doing software raid, though, what's the problem with SATA drives? A generic controller is less than $30, and you can get 80GB models for dirt cheap. -dhbarr.

I haven't measured this but I'd expect it to cut write performance in half if you mirror 2 IDE drives on the same controller. Unlike SCSI, the IDE controllers can only handle one outstanding command at a time so writes to two drives on the same cable won't run in parallel. Software raid5 slows you even more because the CPU gets involved and you force all the drive heads to seek at once instead of independently. > As long as one is doing software raid, though, what's the > problem with SATA drives?

Actually, wouldn't that give you 160GB capacity but you could not lose two drives unless they both happened to be on the same side of the mirror. Why not go with a RAID 5 card (NOT a Promise one though). I am guessing that you'll need the read performance more than the write performance so RAID 5 should be a viable option.

When I first started working here they hired my wife and I as a team. She as the tech coordinator and I as the tech specialist. Budget crunch came and they couldn't afford to keep both of us. Now I wear both hats and it keeps me very busy but gives me first hand knowledge of what teachers are looking for. At any rate I was discussing this topic with her and her opinion is a bulletin board would be better because it helps keep subjects organized. I tend to agree. Here is a prototype. http://www.stmarys-school.org/k12ltspteachers/index.php Our school does not have computer classes per say. The teachers are required to incorporate technology into their regular lesson plans. So there is no set schedule where Mrs. Smith has computer lab every Wednesday at 10:00 am. I may not see Mrs. Smith in the lab for two weeks then I might see her four days in a row. >From my experience, incorporating technology into their lesson plans is a chore for quite a few teachers. Don't get me wrong, our teachers are good with computers and when I've seen them in district technology in-services they stand out in the crowd. But non the less it is still a chore. My cousin has been a TC for 25 years and she has always done all the planning for the teachers. When my wife was the TC here she assisted the teachers with incorporating technology into their lessons but now that they are on their own, so to speak, I see what a chore it is for them. Here's what I know for sure. If you give teachers a lesson plan using any piece of software or even the frame work of a lesson plan they will flock to said software and embrace it. We have one teacher that questions why we aren't using "main stream" software in the lab. I made a couple of templates in OpenOffice for her 4th grade class to use in their studies on US states. She was tickled to death and didn't give me that "I wish we were using the software I have at home." look. I'm now working on making her some lesson plans to incorporate kstars, wikipedia and OpenOffice. Teachers have a pretty full schedule and any software that has lesson plans as part of the package will be embraced.

Not to gloss over the rest of your brilliantly informed email, but what you just said is the Holy Grail of OSS adoption in our schools. I've only recently understood this. I have long known that giving away computers and software is only 16% of a successful computer lab deployment and that the rest is support and education. I think our better-funded proprietary friends get this. So many lesson plans just happen to use expensive software. Hence the need for it. We must change this as vigorously as developers have changed the paradigm of software development. Whether community or privately driven, or both, the Killer App for the widespread adoption of OSS is the Lesson Plan. I have and continue to make the case anytime that I can to our larger corporate friends at HP or IBM or Novell or RedHat or Sun that the K12LTSP and Skolelinux distros are Monumental Drivers of hardware and software sales. By sponsoring these developers and complementing their work with Curricula and Lesson Plans, we have the cost effective way to Smack Down the NCLB, build literacy, and train tomorrow's OSS workforce. --scott -- R.

Does 'mount' show that /home is being mounted at all on the new server? If not, try 'showmount -e' on the server exporting /home and 'showmount -e server_name' from the one with the failing mount.

It
basically has a magnetic clamp that you clamp around a power wire and it
gives a current readout. Multiply this by 120 (volt) to get power. The
nice thing is you don't need to touch any high voltage wire. You will
need to clamp only 1 wire (hot or return) but you can easily build a
short extension cord with wires split, or carefully split the outer
insulation on an existing extension cord and seperate the wires (think
disecting an earthworm in science class). This actually gives you something called volt-amps, which in DC current is the same as Watts. But in AC it is different because we're dealing with a sinusoidal wave of constantly changing voltage and current. To calculate average AC power, you multiply volts x amps x the power factor. The power factor comes from the fact that the voltage wave and the current wave do not match up exactly -- the waves are offset from each other. If you're interested, here's a website I found about it: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/powerac.html Anyway, I'm not an expert on this, but it looks like the power factor is a function of the load, meaning your power supply. The only way I know of to find out your power factor is to hook the power supply up to an oscilloscope and view the voltage and current waves. Measure the angle of offset between them--this is called the phase angle. Take the cosine of this angle and you have your power factor. There might be an easier way, but I don't know it. Maybe you have an electricity teacher at the school who could help out with the formulas and the measurements. Here's another site I found that shows how to measure AC power w/o an oscilloscope: http://home.earthlink.net/~jimlux/hv/varvom.htm They also mention that using a wattmeter will give you good results, because it takes all this business into account for you. -Rob _______________________________________________ No banners.

My root (/) partition is very full and the students could not get logged in. I purged some files and got 50MB of free space.
There is and
I have 3GB root(/), 2GB(/home), 256MB swap and 7GB of free space on the disk in that order.
I moved the swap partition out of the way to the end so as to move /home partition but then Qtparted et Partition Magic does'nt want to redimension or move ext3. I looked up Qtparted homepage and it states that i cant move or resize Ext2 and 3.
1- Does someone know how to increase this partition?
2- I remenber having seen something about adding a partition so as to increase a existant linux partition, has someone seen or used this?

configuration question out of curiosity for future expenditure.

This morning as I was teaching a lesson the server let out a weird,
mechanical noise albiet only for a few seconds.

I was not concerned about the lack of redundancy in the data, but now I
am. It was probably nothing, but My academic questions about the best
configuration suddenly seem more practical.

I gather that many of you have a problem with the Promise raid
controllers. I also see that alot seem to favour the 3ware
controllers. I feel I need to get a solution in place soon, probably
over the Christmas holidays.

So, in a nutshell:

anything wrong with 4 - 80 GB 7200rpm EIDE drives with 8Mb cache running
on a raid controller(as yet to be determined) in a configuration like 1
+ 0 or 0 + 1? This gets me effectively 80GB capacity and redundancy
with the ability to withs! tand 2 drives dying, right?

this would get me, correct me if I am wrong, both redundancy and some
performance increase, yes?

old drives, with no redundancy, are old smallscsi drives of 5400 rpm
speed on old controller

Without raid, if a disk fails, the system dies, or the data becomes unavailable until you replace the drive and restore from a backup.

We've discussed this before, a year or so ago. The consensus seemed then to be that one could use IDE drives with small labs, but beyond 10 users, SCSI's ability to re-order requests made for much more efficient access to the disk. And I think SATA addresses that to some degree, although still not as well as SCSI as I recall. But perhaps doing RAID 0 makes this less of an issue (?). Anyone's thoughts?

In addition to Jim McQuillan's point you also get the performance benefits with RAID0 or RAID5 via striping. Say with a single drive your platters need to make a full revolution to write every bit of data. If you stripe with 2 drives you cut the time in half (theoretically), 3 drives into a third and so on. Because while the first drive is making is revolution after writing the bit the next drive has the ability to write a bit etc. So bottom line is RAID1 and RAID5 get you redundancy with immediate failover, no downtime. And RAID0 and RAID5 gain performance with write speeds. My preference is RAID5 when possible because it gains the best of both worlds, but unfortunately you pay more for the controllers that handle it. If you are on a budget crunch RAID0+1 in my opinion is the next best option. And I personally never trust backups, they are my insurance. But when there is a server down and users on my back I want immediate results that allow me to do repairs in the off hours, and leave the backups on the shelf. Another note is that with RAID0 you get the full total of all of the drive amounts added together (80GB+80GB+80GB=240GB). With RAID1 you only get the total of the one drive (80GB+80GB=80GB). And with RAID5 you loose the size of at least one of the drives in the raid (RAID5 uses 3 drives minimum)(80GB+80GB+80GB=160GB). So RAID5 also makes the most efficient use of your storage capacities while maintaining redundancy and failover. Also with RAID you can buy "Hot Swap" controllers and drive trays (at an extra cost of course). This allows you to remove the bad drive while the machine is running and the RAID rebuilds itself on the fly. Your users never see a difference and your not in after hours. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Just a note about power consumption: The power company bills you by the kilowatt-hour. One kilowatt hour is consumed when you a) use 1 kilowatt for 1 hour or b) use 2 kilowatts for 1/2 hour. I'm mentioning this because the meter at this link looks like it will display either watts or kilowatt-hours. You should be measuring watts. If you need to measure kilowatt-hours for some reason, make sure you run each of your tests for the same length of time. If anybody does a test of power consumption, please post it to the list.

Only READ performace is gained when using RAID5. Also depending on how many drives you use with RAID5 you loose storage. You need a minumum of 3 drives to do RAID5 RAID0 gives the best performance by far but it is not fault tolerant at all.

Is there anyone out there who would volunteer some info? They have a 2003 primary domain controller (for now), and a Windows File Server (for now). They want a server in each of the 3 pilot labs as teacher machines. These 3 servers will have to authenticate to the domain controller and mount home directoris from the file server.

Is this a box that was upgraded from K12LTSP 4.0 to 4.2? Repomd.xml is used by yum 2.0, which is only included in K12LTSP 4.2. ftp://k12linux.mesd.k12.or.us/yum/fedora is a K12LTSP 4.0 repository. It should be: ftp://k12linux.mesd.k12.or.us/yum/fc3/ Off the top of my head, the only way I can think for this to happen is if you installed K12LTSP 4.0, customized /etc/yum.conf, and then upgraded to K12LTSP 4.2. It this is correct, either edit /etc/yum.conf & remove the repositories you don't need (they are now in /etc/yum.repo.d) or copy /etc/yum.conf.rpmsave to /etc/yum.conf. > A related question: I've been using yum for updating and > installing new packages and really like how easy it makes > the process.

There are, of course, other tradeoffs; the redundancy comes at the price of additional disks and a performance impact on writes. There is also a gain in read performance. But disk failures aren't the only way to lose data. A RAID decreases the probability that a hardware failure will cause data loss, but it has no impact on users or administrators deleting or overwriting a file. So having a RAID setup does not eliminate the need for doing periodic backups. -- Mike Wescott Wescott_Mike at EMC.COM From dahopkins at comcast.net Fri Dec 3 19:00:28 2004 From: dahopkins at comcast.net (dahopkins at comcast.net) Date: Fri, 03 Dec 2004 19:00:28 +0000 Subject: [K12OSN] profile.d question Message-ID: <120320041900.19878.41B0B7CC0005FF5500004DA622058860149C0207059F01080E0B@comcast.net> It is Friday, so I get to try and troubleshoot printer problems again.

Scary, Huh? :-) The first CD, especially if you go with Testing, RC2, can install a complete desktop from the CD. Great if you have no network. Since you have a network, just use Synaptic or apt-get to install the rest of the deal. Get your images here http://www.debian.org/devel/debian-installer/ If you want to go lighter on the install CD, use the net-install iso or the business card iso. Both depend on a working network, though. The debian installer, RC2, rocks bells and will configure your wireless nic as early as installation. > > Thanks for the suggestion. my pleasure.

For my first crack at it, this cron job will refuse to run unless "FLASH_SOUND_HACK=YES" is added to /etc/sysconfig/k12ltsp The problem, or potential problem I should say, is that if /tmp/.esd/socket exists then esd will refuse to run except as the user who owns /tmp/.esd/socket. I'm not really sure if that is a serious problem or not, and don't have time to test it much right now. So for now it defaults to skipping this part...

I'm befuddled a bit here -- are you talking about /etc/.esd/socket being created on the client, or on the server? It's only required on the server (to fool flash into thinking esd is running locally) -- and esd doesn't need to run at all on the server... Unless you mean just that -- esd won't run on the server if you enable this hack, in which case I agree it's a bit sloppy if users log into the server locally...

When run, the script should set an environmental variable called SETPRINTERS. If you log into a client (with the script in /etc/profile.d/ at least), that variable should get set. Just run "echo $SETPRINTER" and it should say that it is =true... If that isn't there, then for some reason your profile.d scripts aren't running... hmm... did you make the script executable? run "ls -l setprinter.sh" while in the /etc/profile.d/ directory and make sure you have the "x" bits set, otherwise the script will not run. Run "chmod a+x setprinter.sh" in the profile.d directory again. Try loging in again and see if the variable is set. =) Henry -----Original Message----- From: dahopkins at comcast.net [mailto:dahopkins at comcast.net] Sent: Fri 12/3/2004 2:00 PM To: K12LTSP Cc: Subject: [K12OSN] profile.d question It is Friday, so I get to try and troubleshoot printer problems again. Speciifically, I am trying to get the script on the wiki.for setting the default printer to work. I have created the profile.d entry, and the /etc/sysconfig entry. But, no luck. If I run lpoptions from a shell, it works fine. So ... when do scripts in /etc/profile.d get executed and does it depend on what shell the user has defined? I have also tried the script that uses awk to set the PRINTER variable, but it likewise doesn't work for me. I am sure the solution is simple, I just can't find it.

I'm interested is setting up a bunch of NAS boxes and was looking at that as an option. The following are some notes about raiding focused around smaller terminal server systems (30 - 60) users on 2 to 4 drives. It seems to me that going beyond that number is where you want to pull out the storage component and make it independent of the terminal server hardware. In addition to the redundancy benefit of a mirror (RAID1) which Jim spoke to, the read access behaves just like striping. So a 2 drive mirrored system is capable of supporting many more users than a single drive. Since common usage patterns are generally "attribute intensive" (listing directories, getting file sizes etc)and reading smaller files, the net impact of using a simple mirror is substantial. Stats from hdparm bear this out Applications and usage patterns make a difference. On a small box, RAID1 holds its own for home directories because most accesses are attribute reads. As the size of your server goes up, RAID 5 is good economical home directory solution: Your added cost for redundancy is only 1 additional drive/partition (or 2 drives/partitions if you want hot spares). Software/partition-based RAID has some real advantages in smaller systems: Some items are best left unRAIDed. Swap is better on separate partitions on multiple drives for several reasons. The squid proxy cache prefers unRAIDed partitions on multiple drives. So if you're doing lots of user apps and cache/proxying your users traffic, using software RAID allows you to mix and match partitions on multiple drives most economically. The cost is a small CPU overhead; the saving is an expensive and unnecessary RAID controller RAID1 has another benefit sometimes used as an archiving mechanism. Since the data is similar on both drives, one can be pulled and have all the data available. A fresh drive can be installed and the mirror resync'd. It's also comforting to know that when the machine blows up, booting under Knoppix gives you ready access to all the data on either drive in a mirror. RAID0 trades off reliability for performance (where much of the performance can be regained by a mirror with the added reliability). IMHO RAID0 has little to offer for a general purpose server. RAID10 raises performance and reliability but is the most expensive way of doing it and isn't really appropriate for smaller installations. oo On Fri, 3 Dec 2004 14:43:22 -0600 (CST), Eric Smith wrote > You also might want to consider Raid 10 > http://www.acnc.com/04_01_10.html > > Highpoint makes an excellent card, the RocketRaid, tons of great features > and a company with excellent Linux support (the 8 SATA port version > SCREAMS) > http://www.newegg.com/app/ViewProductDesc.asp?description=16-115-020&depa=0 > http://www.newegg.com/app/ViewProductDesc.asp?description=16-115-012&depa=0 > > > RAID5 is a very good way to protect your data due to the parity but when > > using RAID5 you take pretty bit (up to 75%) WRITE performance hit. > > Only READ performace is gained when using RAID5.
