hi

<alkisg>
Good morning

hey guys, i can't seem to find good instructions for getting printers connected to thin clients working properly, any tips?
02:20
xerox 3117 (works great if connected to server) on ubuntu 10.04
02:26
never mind, i remembered how to do it
02:27
<Appiah>

<jimjimovich>
was someone asking about neatx and greek or russian keyboard layouts?
03:29
it works for me to switch layouts and both English and Russia work with neatx connecting from the NX client for linux
03:31
<alkisg>
jimjimovich: without doing anything? nomachine nx client + neatx-server?
03:31
<jimjimovich>
yup, just works
03:32
<alkisg>
I had to file this one: http://code.google.com/p/neatx/issues/detail?id=65
03:32
...and run `setxkbmap` on every connection...
03:32
<jimjimovich>
interestingly enough, it even works when the keyboards are are mixed up (like, my local machine is set to RU but the remote is set to EN, it still types remotely in English)
03:33
is it a problem with typing or is it a problem that the greek keyboard has more keys or something?
03:33
<alkisg>
I can't type letters like those with the us layout: Καλημέρα
03:33
So I have to switch (with alt+shift) to greek layout
03:34
<jimjimovich>
yeah, same for Russian
03:34
<alkisg>
And without the setkxbmap workaround, neatx-server doen'st allow me to switch layouts...
03:34
<jimjimovich>
strange
03:35
I didn't configure anything at all. Just installed neatx from the ppa on 10.04
03:35
<alkisg>
Cool, maybe something is missing for the greek keyboard then
03:35
I'll try to test with russian kbd when I have some time

by the way, you were absolutely right yesterday about the flash problem

<muppis>
I got nfs related problem on fat clients. Homedirs are shared via nfs and loading gnome everything graphical stops respondig or responds extremely slow.
05:42
<alkisg>
Is statd running on the server?
05:42
<muppis>
Even failsafe gnome hangs.
05:42
alkisg, yes.
05:43
Had earlier issues with that and got fixed, or it doesn't repor any errors anymore.
05:43* alkisg stopped having nfs problems when he started using NFS_HOME_OPTIONS=defaults,nolock :) But other than the statd problem and that workaround, no idea about nfs...
05:44biomorph_ has joined #ltsp
05:50
<muppis>
I think we had to but nolock also to mount options.
05:50
Not but but put.
05:53
<jimjimovich>
anyone got some pointers for using scanners on thin clients?
05:54bobby_C has joined #ltsp
05:55biomorph_ has quit IRC
06:00
<sep>
jimjimovich, i sidestep the issue by using network scanner,
06:00
<jimjimovich>
sep: like actual network scanner hardware or sane network scanning?
06:01
<sep>
harware network scanner
06:01
<jimjimovich>
sep: must be nice :)
06:03
wow, i actually just got it working (with one scanner connected to a thin client). sweet!
06:06
sep: are those network scanners expensive?
06:07
<sep>
depends. some of the copyiner/printer/scanner/fax with stampler holes and booklet machines can be. a simple scanner with nic is not so expencive
06:07
<jimjimovich>
sep: that sounds really cool
06:08
although, after like an hour of googling and digging through old docs, i see that scanning is actually pretty easy with any old scanner that SANE supports

on ubuntu lucid, i'm getting a 'restart required' pop-up box, seems inappropriate since the client can't reboot the server. ideas?

hi all
11:39
anyone have experience with udhcpc ?
11:41
i have a atom tc with alt1c netowrk , have sorted loading module and getting ip during initial boot, but during premount it stops and i just keep getting

<methril_work>
hi all,
11:46
i've a question about xterm session
11:46
i'm trying to just start a local app into the device
11:47
i tryed doing a xterm -e cmd
11:47
s/tryed/tried
11:48
also modifying the xterm -ls and putting the same command into .login file
11:49
still no way :(
11:53* Kyle__ sighs
11:53
<Kyle__>
I just had a student blame my computers/me for not being able to log into her yahoo mail.
11:53
The labs would be so much nicer without students.
11:54
methril_work: Is the issue that it's not starting as a localapp, or that it's not starting when the user logs in?
11:55
<methril_work>
it's not starting when the user logs in
11:55
if you put the command in the xterm session
11:55
it works
11:57
<Kyle__>
If it's gnome, there's a directory you put ascript in, I think.
11:57
What about in a .xession?
12:00
<methril_work>
does not work, neither .xinit
12:00
it's not gnome, i don't need a wm for this particular case
12:00
i try to create a new session (/usr/share/xsessions)
12:01
<Kyle__>
methril_work: I've got special sessions in /usr/share/xesssions. They work pretty well for me. Are they not running?
12:03
<methril_work>
Kyle__, they are not
12:03
maybe is some bad arg to xterm command
12:03
in hte Exec param
12:03
i'll try xterm -e shell_script_that_use_the_localapp.sh
12:04
it works with a xterm session
12:05
<Kyle__>
methril_work: pastebin one of your sessions, and the script it calls.
12:07
<methril_work>
Kyle__, http://pastebin.com/xYJDfZ3P
12:07* Kyle__ grumbles at firefox for being such a slow pig today.
12:08
<Kyle__>
methril_work: Why are you running that in an xterm?
12:09
<methril_work>
Kyle__, because i need X, (a graphic interface, but not wm
12:09Dean_ has joined #ltsp
12:09
<Kyle__>
methril_work: LDM/GDM/*DM will still launch X, even with out specifying to run that in an xterm.
12:10
<methril_work>
uhm... let me try
12:10
<Kyle__>
http://pastebin.com/rW6cVAF4
12:10
That's one from mine that's used daily.
12:16
<methril_work>
is this the same as using LDM_SESSION session var at lts.conf?
12:19
<Kyle__>
methril_work: You can specify one of those sessions in LDM_SESSION, but doing that forces that to be the default.
12:20
<methril_work>
well if i want it for a specific machine, i could do it for that machine
12:22mgariepy has joined #ltsp
12:24
<Kyle__>
methril_work: I dunno. I've never tried it for just one machine or another.
12:25
<methril_work>
well, it does not work as xsession, neither LDM_SESSION param :(
12:25
i don't know what could be wrong
12:25
<Kyle__>
Hum.
12:25
Weird.
12:35
<Mobe>
hi, i have 2 servers with 4G ram each, can one server manage 20 sessions or should i use both servers as a cluster to get enough power to serve those sessions?
12:36
<Kyle__>
Mobe: Depends on what the clients are doing, what cpus are in the servers, etc.
12:37
<highvoltage>
dean_za: I think you're confusing me with someone else, I don't recall blogging about a dhcp problem :)
12:38
<Mobe>
clients will be all using mostly xchat and firefox for 24 hours on JOTA-JOTI weekend
12:38
servers have dualcore intels
12:39
one brand new desktop and another about 6 months old desktop
12:40
<Kyle__>
Mobe: I'm gonna guess that you could get away with one server, unless they all run a ton of tabs at once.
12:40
But that's me, other people may have a different opinon.
12:40
<Dean_>
highvoltage - not blogging it was an irc log
12:41
<highvoltage>
Dean_: ah ok, must be from quite some time ago then
12:41
<Mobe>
last year I had older cpu and server was also routing traffic for 20 windows desktops, throttling badly in times
12:41
<Dean_>
15 april
12:42
<Mobe>
now there will be separate server for routing different networks
12:42
<Dean_>
you made it seem like it was somehting simple / stupid ?
12:42
http://www.nubae.com/logs/ltsp20100415_pg1.html
12:42
<Kyle__>
Mobe: If you're worried, cluster them then. You should always be able to scale back down to one if you don't need all of it.
12:43
Weird weird weird. I'm getting an error on not finding locale-gen when trying to install a debian chroot
12:44
Is there something special you need in the ltsp-build-client.conf that I'm missing?
12:44
<Dean_>
highvoltage: any chance you remeber ?
12:45
<Mobe>
yes, i have the hardware and personal interest on testing the cluster but lazyness makes me ask these...
12:46
<Kyle__>
Mobe: Well, if this is a work situation, I'd cluster, or even manually partition, because I would _not_ want to give the project a black-eye due to performance reasons.
12:46
<Mobe>
if clustering, is the root server part of primary appserver or separate hardware
12:47
one weekend of use for local scout group, knowledge gain will help mee on my job
12:49
if root is separate does it need much cpu and memory or is the work done in app servers
12:50
<highvoltage>
Dean_: according to those logs, I figured it out, but to be honest I can't even remember having the problem (*crunching*)
12:50
Dean_: does your thin client have 2 active network cards perhaps?
12:53* Kyle__ has never done a cluster in LTSP, so can't really help there.
12:54
<Dean_>
it has an atheros chipset alt1c for ether and ath9k for wifi , i had to manually insert alt1c in modules to be loaded to get past initial kernel panic , how can I prevent a module from being loaded so that i can disable the wifi
12:54
<Mobe>
thanks for this Kyle__ , will wait for other opinions too
13:09
<Kyle__>
Anyone awake know the ins-and-outs of the ltsp-build-client script?
13:09alkisg has joined #ltsp
13:11
<mgariepy>
does anybody having problem with defunc process of udhcp on thin client ?
13:11
<Kyle__>
It's ending with "chroot: cannot run command `locale-gen': No such file or directory". Which is weird, since the only reference I can find to locale-gen is in a conditional in /usr/share/ltsp/plugins/ltsp-build-client/Debian/025-locales, and there it's in a conditional...that should keep it from being run.

<mgariepy>
alkisg, did you saw this with your udchp script, i don't have the issue on lucid but i have it on maverick
13:24
<alkisg>
mgariepy: what problem exactly?
13:25
<mgariepy>
every 2 minutes or so, i have a defunct udhcp process on my thin client
13:26
<alkisg>
No idea about that... stgraber wrote the reloading part
13:26
<mgariepy>
do you use the script on a setup somewhere ?
13:26
<alkisg>
I only use the ipappend 3 part, i.e. I don't have udhcp running after it obtains an ip
13:26
<mgariepy>
ok
13:27
<alkisg>
There were some changes and it wasn't working on my setups because of the cisco routers we're using
13:27
...so I had to stop using it

ltsp-build-client calling locale-gen even when the script says it shouldn't?
14:05dobber_ has joined #ltsp
14:09
<alkisg>
Kyle__: what locale do you have on your server?
14:09
(didn't see all of what you said, but I had a similar problem with the greek el_GR.UTF-8 vs el_GR.utf8 locale)
14:16dean_za has quit IRC
14:18
<Kyle__>
alkisg: The server? I think it's the default...but maybe I set it to utf8...
14:18
<alkisg>
Kyle__: echo $LANG
14:18
<Kyle__>
It shows up C.
14:18* Kyle__ frowns.
14:18ogra_ac has quit IRC
14:19
<Kyle__>
I suppose this is part of linux I'm unfamiliar with.
14:19
<alkisg>
Kyle__: use the --locale option of ltsp-build-client, and set it to en_US.UTF-8 or anything other you want, but take care that the extension is UTF-8 and not utf8
14:21
<Kyle__>
alkisg: K, I'll give that a shot in a sec... a class is running now so I don't want to do _too_ much at once.

14:31dean_za has joined #ltsp
14:33
<Kyle__>
alkisg: Nope, still dying in the same place.
14:33
alkisg: The weird thing is that it should never run locale-gen to my knowledge.
14:33
<alkisg>
Kyle__: how did you invoke ltsp-build-client?
14:34
<Kyle__>
ltsp-build-client --arch i386 --chroot debian --dist lenny --fat-client-desktop --config /etc/ltsp/ltsp-build-client-debian.conf --locale en_US.UTF-8 --mirror http://ftp.usb.debian.org/debian/
14:34
<alkisg>
Ah, lenny, no idea there
14:34
Erm, is fat-client-desktop supported with lenny?
14:35* Kyle__ shrugs
14:35
<Kyle__>
I have no idea. I was going to try.
14:35
I'm hoping it will be slightly more stable than ubuntu.
14:35
<alkisg>
I think vagrantc did some tests *after* lucid was released, and it was semi-working
14:35
Nah, I think fat clients are more stable in ubuntu atm
14:35
<Kyle__>
Hum.
14:35
alkisg: I'm having kernel issues unfortunately.
14:36
<alkisg>
Use another kernel :)
14:36
It's much easier....
14:38
<Kyle__>
alkisg: Trying :)
14:38
I was having weird initrd issues. But I'll try again.
14:38
<alkisg>
What's your kernel problem btw?
14:39
<Kyle__>
alkisg: I think it's due to the intel chipset.
14:39
<alkisg>
Graphics?
14:39
<Kyle__>
alkisg: But in a nutshell, it's locking up with "XYZ blocked for 120 seconds"
14:40
alkisg: At which point current processes will run (a little slowly) and _no_ new processes can be launched.
14:40
Just pulled from syslog, "INFO: task apt-key:1580 blocked for more than 120 seconds."
14:41
It will happen with almost any binary. bash, ldminfod, expr, popularity-contest.
14:41
etc.
14:45
<alkisg>
Sounds like an nfs problem...
14:45
or an nbd problem
14:46
<Kyle__>
alkisg: I don't think it's an NFS problem. It can happen on a box before NFS is ever used.
14:46
NBD problem, I dunno. I don't _think_ so, but I'm not sure.
14:49
<alkisg>
Can you try disabling nbd-proxy?
14:49vagrantc has joined #ltsp
14:50
<Kyle__>
alkisg: I can try. This class is over pretty soon, I'll turn it off when it's over.
14:51

<Kyle__>
alkisg: Is the patch the only way to disable the nbd-proxy? What happens if I just turn that off on the server?
14:58
<alkisg>
It's a client process
14:59
<Kyle__>
Ahh ok.
14:59
alkisg: What about just turning it off on the client? Could that be done without altering the image?
15:00
<alkisg>
No. But the image doesn't need updating; only ltsp-update-kernels is needed
15:01
<Kyle__>
Oh I see.
15:01
OK. LIke I said, I'll wait till after class to update... but I'll try that.
15:02
<alkisg>
update ltsp_nbd, call chroot update-initramfs -u, then ltsp-update-kernels.

<johnny>
no
16:35
it's stored on a read only image
16:38
<Kyle__>
OK, running without the proxy for about an hour now. No problems yet, but I'll wait to see how it goes after a full day's use.
16:40
johnny: jconlon: you _can_ add new software on the client. All the changes will be stored in ram, and lost on reboot. That makes it a decent way to test the interaction of new packages, as long as you have enough ram.
16:41* Kyle__ actually just did that with eclipse today: had to make sure it wouldn't insist on a different version of java, or something that would screw up the java-apps my labs require.
16:41
<johnny>
that's not the same thing as managing
16:41
you can't delete
16:42
adding is one thing, deleting and upgrading isanother
16:42
manage to mean, means all of those things
16:42
<Kyle__>
johnny: It's not permanant, but it's enough for testing. If that's what he needed.
16:42
<johnny>
i doubt it was just for testing
16:42
<Kyle__>
johnny: I never did test removing a package.

<jammcq>
just need someone to manage it
20:56
<dberkholz>
i already do that for 2 other projects, wouldn't mind adding a third
20:57
besides, i should do something around here besides occasionally pop my head in

all we need is a list of project ideas and potential mentors, and i can handle the rest
