[Ltsp-discuss] deal on EeePC
I'm posting this because I know some folks have mentioned using the EeePC as a thin client. www.newegg.com has a deal on Dec 1 where if you buy a Xerox 6130 color laser printer (currently $374, free shipping) you get a free EeePC (4G-BK029, 7 screen model). The printer's got good ratings, so it seems like a pretty sweet deal. -Rob The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

Re: [Ltsp-discuss] LTSP over WAN
Go to the #ltsp IRC chat and ask. The folks from Revolution Linux, who do LTSP clustering, can often be found hanging out there.

Like you say, I put an applications server at each location. Each user has a preconfigured 'default' location, and their /home/$USER is stored on the local applications server. Then, at each remote location, they have their home directory set to /remote/$USER, which is an autofs NFS mount back to their 'default' location. It works pretty well, considering we're loading /home/$USER over just a T1 -- I turned off Firefox's disk caching to prevent ~/.mozilla getting too large and caching over the WAN. It takes awhile to log in (maybe 20-30 seconds) but once you're up and running it's very fast. Interesting. Would love to know more. In our setup since bandwidth costs were beyond our budget we run and hourly rsync of /home in round robin fashion syncing A--B--C--D--A servers respectively at 00, 15, 30 and 45 minutes past the hour. Since travel time between sites is minimum an hour this works pretty much okay. However we are yet to get to solving the issue of authentication changes when users change a pass word at one location ...we are testing LDAP master slave combination. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

[Ltsp-discuss] GDM LTSP4.2 Autologin
I am in the process of installing LTSP4.2 on Mandriva 2009. There has been
problem because i has not found specific instructions for Mandriva 2009 but
Instructions for Mandriva 2006 and 2007 work 95% of the time.
What i have to solve now is autologin on some terminals.
I have tried instructions for KDM and GDM and none works.
I has gone back to GDM and use this instructions:
#
Create a user ID for each client machine that will autologin. This how-to
assumes the IDs are auto1, auto2, auto3, etc.
Create the /usr/bin/autologin script. This script figures out which client it's
running on and then passes a correpsonding login ID to GDM for the autologin.
Here's a sample script, which you can modify to suit your needs:
autologin script--
#!/bin/bash
CLIENT=$(echo $DISPLAY || cut -d. -f1)
case $CLIENT in
ws001)disp=auto1;;
ws002)disp=auto2;;
ws003)disp=auto3;;
esac
echo $disp
Be sure the $disp variable is being set to valid user IDs you created in the
previous step. Remember to make the autologin script executable ('chmod +x
/usr/bin/autologin').
Modify /etc/gdm/custom.conf and add the following settings under the daemon and
security sections. Be sure to include the pipe character at the end of the
TimedLogin line.*
---custom.conf
daemon
AutomaticLoginEnable=true
TimedLoginEnable=true
TimedLogin=/usr/bin/autologin|
TimedLoginDelay=30
security
AllowRemoteAutoLogin=true
Restart GDM. This will kick all users, including you at the console, off the
system and send them back to the login screen. As such, it's best if you switch
to a command prompt console by pressing Ctrl-Alt-F1, and login in as root, if
you aren't already. Then, restart gdm:
gdm-restart
###
There are other similar procedures that i has tried too without luck.
The problem is that i can see the login screen on the terminal and a message
that say somthiong like
root wil login in 30,29, seconds but root never login and th message
start again root wil login in 30,29, seconds and so on. I DO NOT WANT TO
LOGIN AS ROOT BUT AS A REGULAR USER. auto1 in this case.
What i thing is that something is missing because i do not see how the value
auto1 stores in $disp on the screen, is passed to GDM as the name of the user
i want lo login as.
Any help?

Re: [Ltsp-discuss] LTSP 4.2 ctrl+alt+F2 gone
The problem was my fault. In order to have correctly displayed on KDE, (bottom right corner of the screen) the flag of the country (on the terminals), because ERR was displayed instead. I copied from Mandriba 2009 /usr/share/X11/xkb/symbols over /opt/ltsp/i386/etc/X11/xkb/symbols.

[Ltsp-discuss] Streaming (on demand) applications - natural development from local applications
The example below is from the Microsoft world, but it illustrates a feature / direction that could be very powerful with LTSP. I was discussing with an IT expert at school about how to deliver some multimedia programs we are given by the Ministry of Education here in New Zealand. What does the software do: Every 2 months or so a new title comes out on CD. Each CD contains several interactive stories. Basically, you read the story on the screen and you can also listen to the story by clicking the text. By clicking on highlighted words you can also hear a definition of the word. Finally, you get to do activities related to the story, such as making a comic strip or writing a letter. Technical details: The software only runs on windows (almost runs on wine). It is created with Shockwave Director and runs as a standalone exe file with accompanying media files (MP3s etc.) In total each program takes up about 100MB on disk. Due to the multimedia nature of the program it is not suitable for thin client use. I have tried running it with LTSP wine and using MS terminal services. In both cases latency is a problem. When I mouse over an image, it takes about a second for the corresponding audio to play. Traditional approach: The traditional approach to implementing such programs is to have locally installed windows xp workstations. A windows xp image is created containing these programs. The operating system is installed by copying the image to the workstations over the network. This is copying of the image is generally only done once, but needs to be done again everytime a new program is installed on the image, or in the case where a workstation has operating system or software problems. Problem with traditional approach: The problem is that every time a new CD comes out from the Ministry of Education, we have to update our image and copy it over to all the PCs on the network. The image keeps getting bigger, even though only a few people will actually want to use this program. Suggested solution (Virtualised On-demand Applications): Instead of installing the programs in the image,the applications are virtualized, allowing them to run without installation. This keeps the image and image size constant. When a user wants to run a particular program, the program is copied to the local harddrive (could also be ramdisk or flash drive) to be run locally. I didn't ask what software you use to do this, but on wikipedia I found that VMWare has a program called ThinApp and MS has a similar program. http://en.wikipedia.org/wiki/Application_virtualization http://en.wikipedia.org/wiki/Application_streaming I am not sure what is available on linux to do this. http://searchenterprisedesktop.techtarget.com/tip/0,289483,sid192_gci1328103,00.html Advantages: You get the advantage of a locally run application without bloating the system image (ie space needed on the workstation). You also get the advantage of a centrally managed system without having to push out images everytime a new program gets installed. Thoughts for LTSP (Lowfat clients (DRBL) -- Local Apps -- On-demand Apps): *** The trouble with lowfat clients is that all the programs you want to run have to be installed on the local machine. The more programs you want to run the more RAM you need and the longer it takes to download the system on boot. The whole system has to download even if you are not going to use all the programs. Local apps minimise this problem by running most programs on the server, but once again any program that you want to run must be downloaded with the system. In the case I described above this would become unmanageable. 100MB added to the system for each program would soon fill up RAM. And these programs are only used by a small number of users and only one at at time. Streaming (on demand) applications for LTSP: With on-demand applications, the size of the system image can be minimized. If someone chooses to run a program that needs to run locally, it is copied to the RAM disk (or local media) on the client to run locally. This way a range of locally runable applications is available to everyone, but still the system requirements are less for the clients (one of the original advantages of LTSP), because each person is only storing locally the programs they need to run right now. What does everyone think? Isn't this a natural development for LTSP? - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/_ Ltsp-discuss mailing list.

[Ltsp-discuss] LTSP5 - ldm: su user problem
Recently, I had some trouble working with ltsp: I logged in on one of the ldm-servers I specified. Then I changed the user and tried to open a program: [EMAIL PROTECTED]:/amnt/home/Peter.Stein$ su ripley* *Password: * *Last login: Thu Nov 20 15:16:38 2008 on pts/5* [EMAIL PROTECTED]:/amnt/home/Peter.Stein$ vim* *X connection to localhost:14.0 broken (explicit kill or server shutdown).* This also happens with root. So it is not possible to start a program as another user. This doesn't affect a normal user, but of course the administrators. ldm uses a secure ssh channel which is created by the user who logs in via ldm. That probably causes the problem. A possible workaround might be to identify `su user` with `ssh [EMAIL PROTECTED], but I am not sure if that has other implications. Did anyone of you find a proper way to deal with this problem?
