Anyone know how I > could script the opening of an image on my terminals? Thanks in advance, Duncan, there are several ways to "pop" a picture on the user's screen. You can have an user app waiting for picture showing up in a preset place - that can be run from .bash_profile. You can have a single app waiting and displaying the pic on all terminals - for that you need a list of current DISPLAY variables (I use the single app approach). It is surprisingly easy. How does the picture appear on the system? How would an app know about it? julius From ltsp at dunc-it.com Tue Sep 1 19:35:10 2009 From: ltsp at dunc-it.com (C.

The fact that the USB stuff doesn't work is a poor reason to force the clients to use 32 bit software. I was hoping to get local apps working on the clients as part of this.

Phydeaux, we don't mean to seem rude or unhelpful, it just seems like the smart thing to do would be to have a i386 chroot for the thin clients. I understand why you'd want the server to use the x86_64 version, as it's likely to be addressing larger memory spaces. We just don't get why you'd want to be the guinea pig for x86_64 on the thin client? (And you would be, cause I'm guessing very few people build the chroot for the thin client as 64 bit.) I'm sure the developers will fix the USB problem that the x86_64 clients have, I just don't expect to see it this week. In short, blow away your chroot and rebuild it as i386. Hopefully, down the line, they'll fix this and you can try out the x86_64 chroot again. Personally, I avoid the 64 bit stuff, unless I need it on a big server, because it's still young and not supported or tested as well as 32 bit. (That and you didn't have a lot of 3rd party binary stuff that worked on x86_64, since it was all 32 bit.) IT's not because the dev team isn't trying, but it's been running on i386 longer, and there are still many more users on i386, at least for booting the thin clients. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iEYEARECAAYFAkqfaxIACgkQxWV7OPa/g5GmcgCeOuHzakPdD2gUeqG+2I9m9f1g QpkAnjFG01iZAETCSF7rRoMspxPPIWDW =8Obg -----END PGP SIGNATURE----- From burke at thealmquists.net Thu Sep 3 07:12:23 2009 From: burke at thealmquists.net (Almquist Burke) Date: Thu, 3 Sep 2009 02:12:23 -0500 Subject: [K12OSN] Adobe Flash In-Reply-To: <4A9F12F5.5020709@bittware.com> References: <4A9F12F5.5020709@bittware.com> Message-ID: <5BE61341-70AC-4479-88D5-0E94B5082DD3@thealmquists.net> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On Sep 2, 2009, at 7:51 PM, j.w. thomas wrote: > I'm running K12LTSP-EL5-64 (The 64-bit Centos-based version) in a > one-room multi-grade school.

I'm not positive which version of FF I've got, as I do not have remote access to the system and I'm not there ATM. I'll get back on that in a couple of hours. When I go to about:plugins, I do get something - I don't recall the exact words, but they are in effect saying "no plugins" and point me to two addresses at mozilla for finding out about them. I tried Youtube to test for Flash. No joy there. It may be that they are using director, but since I'm positive flash isn't working and that's what she's asking for, I'd prefer to continue pursuing that until the request is amended. -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas at bittware.com http://www.bittware.com (603) 226-0404 x536 The secret to enjoying your job is to have a hobby that's even worse - Calvin's Dad From bfristen at shaw.ca Thu Sep 3 12:14:37 2009 From: bfristen at shaw.ca (Brian Fristensky) Date: Thu, 03 Sep 2009 07:14:37 -0500 Subject: [K12OSN] Adobe Flash In-Reply-To: <4A9F12F5.5020709@bittware.com> References: <4A9F12F5.5020709@bittware.com> Message-ID: <4A9FB32D.2050004@shaw.ca> j.w. thomas wrote: > I'm running K12LTSP-EL5-64 (The 64-bit Centos-based version) in a > one-room multi-grade school.

We're now using the i386 chroot for the clients. We had no idea that we were the Guinea pigs for the x86_64 clients. Then again, if nobody uses the x86_64 software, the bugs in it won't be found and fixed nearly as fast. We ran all last year with x86_64 clients and the _only_ issue we had with it that did not also exist in the 32 bit clients was the USB problem. That seems pretty good to me.

Or check your lan cards - do they have boot ROM sockets? Can you > get boot ROM for your ethernet cards? > The other alternative is to boot the EtherBoot image from the hard disk itself. This way, there's not floppy or CD-ROM to misplace or "grow legs and walk away." All you have to do is cat this image to /dev/hda or whatever your hard disk is (/dev/sda, on SATA or SCSI systems). The way I do it is by first copying the EtherBoot image to a file (usually a formatted floppy, since the EtherBoot image is so small), then booting Damn Small Linux on the old PC. Then, just mount the floppy ("mount -t vfat /dev/fd0 /mnt/floppy" or something similar), and "cat" the EtherBoot file directly to your hard disk. If you've already made an EtherBoot floppy and would like to skip any mounting of floppies, you can do that, too. Again, boot Damn Small Linux on the old PC, then pop your prepared (and tested!) EtherBoot floppy into the drive. Then issue this command. cat /dev/fd0 /dev/hda Either way, what you're essentially doing here is turning your old PC's hard disk into an "EtherBoot hard disk." It's acting just like a giant EtherBoot floppy. Of course, you won't be able to boot any other OS's from that hard disk this way...and for an old PC acting as a thin client, that is a good thing. If the old hard disk goes belly-up, no problem, just pop another old one in there, cat your floppy over, and you're back in business. --TP _______________________________ Do you GNU ?

I have found that on some motherboards setting the boot options to boot from LAN is not enough. Sometimes you also need to enable the LAN boot ROM option found elsewhere in some chipset options. It sounds odd since usually there is no LAN boot ROM socket with onboard chipsets, but in many cases enabling that option has allowed systems that wouldn't otherwise boot of the onboard NIC to work.

It's always mystified me why there's a market for that, because Windows NT Server has supported RAID-1 since v3.50 from 1994.

If you want to do a couple of mirrors like you're describing, there are better ways to do it. The first is to get a real RAID card, that is supported by Linux, that doesn't break the bank.

The second way to do it, if you're hesitant about money for the RAID card, is to go ahead and do software RAID, but not with ASUS's controller. Like Windows NT Server, Linux also supports software RAID directly, and mirroring isn't all that CPU-intensive. --TP _______________________________ Do you GNU ?

I went with 2 500G sata, use one for storage, then rsync it in the middle of the night. I was paranoid how easy it would be to take the disks out of that box and throw them in something else if this system dies. At worst, I lose something that's not synced yet. Of course, I could cron the sync job to be every 5 minutes or so. 3 total drives, 1 for OS and home dir, one for storage, one for backup of storage.

The rsync copy does have the advantage of possibly surviving some types of disasters that would crash the system before being copied, though. -- Les Mikesell lesmikesell at gmail.com From rie at pcfubar.net Tue Sep 8 21:52:13 2009 From: rie at pcfubar.net (roger) Date: Tue, 8 Sep 2009 14:52:13 -0700 Subject: [K12OSN] Two SATA mirrors In-Reply-To: <4AA6C9D6.3060308@gmail.com> References: <4AA69153.1000108@cmosnetworks.com> <4AA6C9D6.3060308@gmail.com> Message-ID: On Tue, Sep 8, 2009 at 2:17 PM, Les Mikesell wrote: > Software raid is just as easy to move as a single drive - in fact if you > move a single drive both copies will still work. ?

My old system was starting to act flaky, so I was kind of in a hurry to get something built and in use. I'll keep this method for a while. If I outgrow 500G maybe I'll look at that. I haven't updated computers since I built my 600 Mhz machine a few years back. The quad-core intel I used on the new sure makes a big difference.

In your AP hardcode the dns #(s) that the thin clients are using, if this number does not work,use a public dns number hardcoded into the AP. This will pass the correct dns info to the laptops. I assume your k12 server is providing the dns,and not a remote server doing dns for your lan? There are a few variables here that are not really defined? Do you have iptables enabled? I assume you have a border firewall before any machines, including your k12 server, on your lan get out to the internet ? Let us know your progress.

Software RAID, especially for /home, is pretty darned easy in Linux. It's only slightly more difficult to make both disks bootable as you have to remember to install GRUB on each one. There's really no reason not to do it, especially with hard drives only costing $40-50 in the sizes you are using. There's nothing wrong with being paranoid. That's why I rsync my RAID to yet another drive each night.

You don't mention how you are authenticating, but I have found that if I don't have nscd running on our systems (both the ltsp server as well as the authentication server), then logins can be exceptionally slow. We have 1300+ accounts active at present and no issues with logins but we are also still using LTSP 4.2. I also noticed during my testing of K12Linux that logins were very slow but thought that was due to a bug (have to search the LTSP forum) which was fixed in a later patch.

Thanks, Daniel Daniel, K12LTSP is based on LTSP5, which uses ssh to login to the server. Can you test to see if running: ssh -Y user at server from another box takes a long time? If so, then add "-vvv" to the ssh command line, like: ssh -vvv -Y user at server This will make ssh verbose and you will see at what point it hangs. By default, sshd on the server runs through several authentication mechanisms, and if it takes earlier/unused ones time to fail, you'll feel it. You can optimize things by identifying the one that fails and turning it off in the sshd_config file. A common one I have seen is: GSSAPIAuthentication Sometimes, setting that to "no" will speed up ssh logins a great deal. -Gadi -- -------------------------------------------------------- Gideon Romm | Proud LTSP Developer ltsp at symbio-technologies.com Pay It Forward!

Our situation is a little out of the ordinary as we are automounting the users home directories exported from a Windows 2003 AD integrated file server via the built in Unix NFS server tools. The exported home directory is actually the Windows account individual document shares. This works pretty well so far, except that all users logging in via GDM get a really annoying popup message telling them their home directory permissions are incorrect. It seems to be related to the following bug report: -------------------------------------------------------------------- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365606 -------------------------------------------------------------------- Making changes on the NFS server side is probably not going to work, as custom configuration of the NFS server is limited to a couple of checkboxes, and I've pretty much tried them all at this point. I've tried the following suggested work around with no success. It seems as if the included GDM version 2.16 does not support these options on CentOS 5.3? -------------------------- /etc/gdm/custom.conf [security] RelaxPermissions=2 CheckDirOwner=false -------------------------- Any suggestions? If I have to, we can look at mounting the exported home as a subdirectory, but I would really prefer to make this work as is, it solves a lot of problems with students misplacing their documents when transitioning back and forth between Linux and Windows labs.

A "telinit 3; telinit 5" ought to do it too.

I spun them ~2 months ago, but the kernel would crash on my 32bit test system so I didn't feel comfortable releasing it. I don't have time to look at it. https://fedorahosted.org/k12linux/wiki/InstallGuide If you want to use Fedora-11 based LTSP, you should install it on regular LTSP using the procedure for standard installation. It is a bit better than the Fedora-10 version. I have been committing small fixes to LTSP upstream and K12Linux so it will work with the upcoming Fedora 12, but otherwise you will see no new features in LTSP Fedora. Upstream LTSP has some newer stuff like ltsp-cluster that isn't yet tested or packaged for Fedora. It could possibly work for Fedora with little trouble, but without others stepping up it wont happen. Fedora 12 LTSP will be about the same as Fedora 11 with one big difference. Fedora 12 32bit has a minimum requirement of i686 architectures. There is no turning back, the decision was made months ago and all binaries are now i686 minimum. Some of you already know that I've been assigned to work on other projects. I might be working on something better than LTSP that I can't talk about yet. I'm putting in some minor effort when I can to keeping LTSP working with the latest versions of Fedora. If folks want more, then some volunteers really need to step up and do the development. I'm even willing to train you if you are serious about it. But history has shown that plenty are willing to consume but few contribute.

We're still chasing a problem with 1000+ accounts causing login slowdowns that doen't happen in K12LTSP/CentOS 5. I just put K12Linux on a T105 for a 1:1 classroom server, and since I won't have that many accounts, and assuming I can solve the video issue with my IBM R31 Thinkpads, I'm planning to use K12Linux. I did have to use Andrew's SWCursor trick on LTS.CONF to get the mouse working on the HP thin clients however. (Thanks Andrew!) It was also a bit of a pain that I had to manually install OpenOffice (which was included in K12LTSP) but I understand the rationale.

Thanks Odin. I will do this if I cannot get sshd working. The part I did not know was /opt/ltsp/i386/usr/share/ldm/rc.d/ which I assume runs at login.

It has been a while since I set it up but I don't recall doing anything special, other than perhaps setting "PermitRootLogin yes" in the sshd_config. Not sure what you have done so far but I am pretty sure you will need to chroot into the client image on the server and manually fire up sshd so it can generate the server keys etc. After that I think it just worked on the clients.

LTSP5 has a whole system for starting processes after X launches, but before the greeter. There are in fact two different paths of interest in your chroot: .../usr/share/ltsp/xinitrc.d/ (This is used for ANY graphical screen script, ldm, rdesktop, etc) .../usr/share/ldm/rc.d/ (This is used only for LDM) If you create a script prefixed with the capital letter "I" (as in "init"), this script will be *sourced* after X initializes but before the greeter. This is the ideal place to put a call to x11vnc. Just make sure you call x11vnc to die along with X, so it starts up every time and does not daemonize or anything. You will find other scripts in those directories as examples. If you are running an image-based distro, such as ubuntu, remember to update the image after making changes. -Gadi -- -------------------------------------------------------- Gideon Romm | Proud LTSP Developer ltsp at symbio-technologies.com Pay It Forward!

However, it is still recommended for anyone who wants to encrypt traffic to the client. It has the added benefit that x11vnc is only launched when needed, thus not consuming resources on the client continuously.

There are methods to encrypt the vnc connection, as wel, so maybe you guys are doing that, too? If not, don't be lulled into a false sense of security. In fact, it's more secure to not have sshd running at all then it is to have it running for the purpose of launching something. Also, keep in mind, x11vnc can also be launched from (x)inetd. So, if you are looking to achieve having it launched "on demand", that would be another way to go without sshd. When its all said and done, though, I think if x11vnc introduces enough overhead to the running system to make it not work well, whether you introduce that overhead at the start or only while someone is working, I think the user's not gonna be happy with you. :) Also, sshd+x11vnc necessarily has more overhead than x11vnc by itself, even if not running all the time. In my limited experience, I never saw much overhead to x11vnc at all on the user's session - only on the vnc connection made. Now, if you *still* want sshd installed, once you install it, you should, in the chroot, make it run on boot just like any other service. In a redhat/fedora environment, I guess that is with chkconfig while chrooted, or some such? I know on ubuntu, it would be with update-rc.d. -Gadi > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- -------------------------------------------------------- Gideon Romm | Proud LTSP Developer ltsp at symbio-technologies.com Pay It Forward!

I thought about this Gideon. I *could* launch x11vnc from the script locations you mention. The problem with this is that x11vnc needs to launch with a password option from a password file to be secure. So if users have access to this password file they too can snoop in on any user. The problem is /root/ or any dir the client has access to is nfs exported. So really anyone with a laptop and some Linux knowledge should be able to vncviewer anyone. This is unfortunately the case with k12ltsp and fl_teachertool currently. I sent out a security advisory to this list a while ago about it. Fortunately, it has not been an issue for me and I suspect others because of the age/experience of our users. At least to my knowledge ;-) However, now that I have sshd running I can *push* a unique password file to each client run x11vnc and then promptly delete the password file. So it's much more secure. Not secure in terms of sniffing bandwidth (vnc is still vnc) but the password file is no longer easily accessible this way. BTW I set the sshd_config settings to disallow password auth (only keys are allowed). You are correct though that sshd listening on the client will add a bit more load to the client. Unfortunately, I don't think there is another secure way of doing things. Nor do I have the time to figure it out if there was. As for x11vnc load: Yes it does make the client slow when it's polling the clients X. But this was always the case. If you monitor people their systems get slow. That's why I implemented vncsnapshot. With vncsnapshot the slow down is for a fraction of a second.

Disallowing password authentication and allowing only keys ensures security even if the client image is available publicly (eg: via NFS) Here's a link to the configuration I use: http://wiki.ltsp.org/twiki/bin/view/Ltsp/X11vncLocalApp > When its all said and done, though, I think if x11vnc introduces enough > overhead to the running system to make it not work well, whether you > introduce that overhead at the start or only while someone is working, I > think the user's not gonna be happy with you. :) Also, sshd+x11vnc > necessarily has more overhead than x11vnc by itself, even if not running > all the time.

The overhead of having sshd listening is _much_ less than having x11vnc running. I agree that when running sshd+x11vnc _will_ slow the client down, in my case this is only going to be used for remote support and the user will not care about the slowdown during the time that remote support is being provided.

Note the -localhost flag. If only secure (ie: ssh) logins are allowed on the client, and only local connections are allowed to vnc, then it is secure.
