| 14:22 | * computer_freak_8 testing | |
| 14:22 | <computer_freak_8> okay, I remember how to do IRC now. :)
| |
| 14:23 | I'm having some issues with an LTSP server I setup - it's probably user/admin (my) error, but it's frustrating nonetheless.
| |
| 14:24 | <highvoltage> hey computer_freak_8. fire away with your questions I'm sure someone will be willing to help
| |
| 14:24 | <computer_freak_8> It can boot, and show the login screen, but fails after username/password are entered; in the logs, I see "nbd9:" complaining.
| |
| 14:24 | "unknown partition table", followed by
| |
| 14:24 | "NBD_DISCONNECT"
| |
| 14:24 | followed by
| |
| 14:25 | "Receive control failed (result -32)"
| |
| 14:25 | and finally "queue cleared"
| |
| 14:25 | thanks, I'm a slow typist. :)
| |
| 14:25 | I found this: http://ubuntuforums.org/showthread.php?p=8517198#post8517198
| |
| 14:26 | but it didn't seem to help much yet.
| |
| 14:26 | <highvoltage> do you get a login screen again?
| |
| 14:26 | <computer_freak_8> yes, I do
| |
| 14:27 | <highvoltage> it's possible that those nbd errors are unrelated, it seems that you do at least haver your root filesystem mounted (since you can boot your thin client)
| |
| 14:27 | have you tried running the following on the server?
| |
| 14:27 | sudo ltsp-update-sshkeys
| |
| 14:27 | <computer_freak_8> true, as well as SSH working.
| |
| 14:27 | <highvoltage> sudo ltsp-update-image
| |
| 14:28 | <computer_freak_8> running that again now...
| |
| 14:28 | <highvoltage> that's usually something people leave out when installing ltsp on ubuntu
| |
| 14:28 | you should restart the thin client after doing that
| |
| 14:28 | <computer_freak_8> I'm actually on Debian, but they're similar enough, I can usually translate back-and-forth
| |
| 14:29 | <alkisg> dgroos: pong?
| |
| 14:29 | <highvoltage> ah, did you manually configure nbd? debian uses nfs by default
| |
| 14:30 | <computer_freak_8> Oh, good question. Not that I'm aware of, but I couldn't even get to the login screen before I disabled the kernel NFS parameters.
| |
| 14:30 | * alkisg thinks that running ltsp-update-image on debian automatically switches it to nbd | |
| 14:30 | <computer_freak_8> default ltsp
| |
| 14:30 | label ltsp
| |
| 14:30 | kernel ltsp/i386/vmlinuz
| |
| 14:30 | append ro initrd=ltsp/i386/initrd.img nbdport=2001
| |
| 14:31 | that's my pxelinux.cfg/default file
| |
| 14:31 | (the one that gets me to the login screen)
| |
| 14:31 | alkisg: possibly, but is that good or bad?
| |
| 14:32 | <highvoltage> that looks good
| |
| 14:32 | <alkisg> I haven't seen the whole conversation, I just saw the "I don't know how I switched to nbd" part
| |
| 14:32 | <computer_freak_8> Oh, okay. LOL.
| |
| 14:32 | <alkisg> If you're asking in general about nbd vs nfs, there are pros and cons to both cases
| |
| 14:32 | <computer_freak_8> Is one better than the other for limited-RAM clients?
| |
| 14:33 | <highvoltage> alkisg: he can't log in at ldm and sees a bunch of nbd errors while it restarts
| |
| 14:33 | (super-short and simple summary)
| |
| 14:33 | <computer_freak_8> but I can login via SSH... which really confuses me.
| |
| 14:35 | ddave7 has joined IRC (ddave7!~Miranda@109-183-95-158.tmcz.cz) | |
| 14:35 | <highvoltage> do you have to type 'yes' when logging in via ssh?
| |
| 14:36 | <computer_freak_8> I did the first time.. but I'd never logged in from my workstation to that IP before, so I figured it was normal.
| |
| 14:36 | markit has joined IRC (markit!~marco@88-149-177-66.staticnet.ngi.it) | |
| 14:37 | * alkisg commends on part of the discussion as he reads them... | |
| 14:38 | <alkisg> (05:24:29 μμ) computer_freak_8: It can boot, and show the login screen, but fails after username/password are entered; in the logs, I see "nbd9:" complaining. ==> that's normal, it's a test to see if there's a newer nbd image
| |
| 14:38 | It's normal that nbd9 gets disconnected
| |
| 14:38 | <computer_freak_8> Oh, okay.
| |
| 14:39 | <alkisg> !SCREEN_08
| |
| 14:39 | <ltsp> alkisg: SCREEN_08: To get a root shell on a Debian thin client, put SCREEN_07=ldm, SCREEN_08=shell and SCREEN_DEFAULT=07 to lts.conf..
| |
| 14:39 | <alkisg> computer_freak_8: from SCREEN_08, run: ssh user@server
| |
| 14:39 | Replace "user" with an existing username, but leave "server" as it is, don't change it with anything
| |
| 14:39 | See if you get any warnings at all, e.g. "adding ssh keys for pc xxx"
| |
| 14:40 | <computer_freak_8> by "from SCREEN_08", you mean, from my SSH shell?
| |
| 14:40 | <alkisg> You have ssh to the client?
| |
| 14:40 | ddave71861 has joined IRC (ddave71861!~Miranda@193-4.gprs.tmcz.cz) | |
| 14:40 | <alkisg> Lets start over
| |
| 14:40 | To troubleshoot the problem, you'll need a root shell on your thin client
| |
| 14:40 | The screen_08 above is a method to get such a shell
| |
| 14:40 | <computer_freak_8> okay, got it. wasn't thinking there..
| |
| 14:40 | <alkisg> ok
| |
| 14:41 | ddave7 has left IRC (ddave7!~Miranda@109-183-95-158.tmcz.cz, Ping timeout: 258 seconds) | |
| 14:44 | ddave7 has joined IRC (ddave7!~Miranda@32-5.gprs.tmcz.cz) | |
| 14:44 | <computer_freak_8> shoot. Apparently VirtualBox doesn't allow [Ctrl]+[Alt]+[F-key]
| |
| 14:45 | gotta grab a physical thin client, one moment...

| 14:49 | <alkisg> computer_freak_8: right ctrl+fx
| |
| 14:49 | (in vbox)
| |
| 14:53 | <markit> btw, don't know if related, but with Kubuntu after login crashes if you have effects enabled
| |
| 14:53 | computer_freak_8: are you using kde by chance?
| |
| 14:53 | * markit knows that he is almost alone on this planet to use KDE with ltsp | |
| 14:54 | <computer_freak_8> Not that I'm aware of. I think it's either Gnome or LDM.
| |
| 14:55 | it has the "LTSP.org" login splash-screen
| |
| 14:55 | if that helps.
| |
| 14:57 | for the SCREEN_0n variables, what syntax should I be using from my shell prompt? Is "set -e SCREEN_08=shell" sufficient for 08?
| |
| 14:57 | oh, wait, that was another post..
| |
| 14:58 | ssh user@server, replacing "user"...
| |
| 14:59 | I tried, from the thin client's shell, "ssh root@server"
| |
| 14:59 | ddave71861 has left IRC (ddave71861!~Miranda@33-4.gprs.tmcz.cz, Ping timeout: 258 seconds) | |
| 14:59 | <computer_freak_8> it said root@server's password:
| |
| 14:59 | dlezcano has left IRC (dlezcano!~dlezcano@nat/ibm/x-uxmjvvssridpsowv, Ping timeout: 260 seconds) | |
| 15:00 | <computer_freak_8> so I gave it, but it said "permission denied, please try again:"
| |
| 15:00 | all three times
| |
| 15:01 | <alkisg> The default ssh settings dissallow root from logging in
| |
| 15:01 | Try with a user
| |
| 15:01 | <computer_freak_8> ah, okay.
| |
| 15:02 | is it okay if the user is a "sudo-er"?
| |
| 15:02 | <alkisg> sure
| |
| 15:02 | bbiab
| |
| 15:03 | Gremble has left IRC (Gremble!~Ben@cpc12-aztw24-2-0-cust146.aztw.cable.virginmedia.com, Quit: I Leave) | |
| 15:03 | <computer_freak_8> okay, that worked - a couple of notes, though:
| |
| 15:04 | 1. I couldn't login to tty3 as myself; I had to login as root
| |
| 15:04 | 2. when ssh-ing to "server" as myself, it corrects the hostname after I login.
| |
| 15:05 | <alkisg> Did you get any warnings about "adding ssh key for pc xxx"?
| |
| 15:05 | <computer_freak_8> nope
| |
| 15:05 | <alkisg> OK, now logoff from ssh, press alt+ctrl+f7 to switch to ldm, and try logging in with the same user/password that you used before
| |
| 15:06 | <computer_freak_8> so logout of ssh, but stay logged into the root prompt?
| |
| 15:06 | <alkisg> Yes
| |
| 15:06 | <computer_freak_8> okay, one moment
| |
| 15:07 | It didn't work.
| |
| 15:07 | <alkisg> (don't pay too much attention to this as is doesn't matter: about (06:04:25 μμ) computer_freak_8: 1. I couldn't login to tty3 as myself; I had to login as root
| |
| 15:07 | you should have tried tty2, where you'd get a shell without logging in)
| |
| 15:07 | <computer_freak_8> It appeared to do the same thing as before - just re-start the login screen
| |
| 15:07 | <alkisg> OK, now let's see the logs
| |
| 15:07 | On your server, check /var/log/auth.log
| |
| 15:07 | Do you see both of the connection attempts there?
| |
| 15:08 | <computer_freak_8> under the chroot, or the main part?
| |
| 15:08 | <alkisg> The one from tty3, and the one from ldm?
| |
| 15:08 | The main part
| |

| |
| 15:08 | jared = my username
| |
| 15:08 | <alkisg> OK, so you did login, and probably something crashed X, and you logged out
| |
| 15:09 | Now, put /home/jared/.xsession-errors to pastebin
| |
| 15:09 | !pastebin
| |
| 15:09 | <ltsp> alkisg: pastebin: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here..
| |
| 15:09 | <computer_freak_8> quick question: what are all those things being posted from the "ltsp" username?
| |
| 15:10 | <alkisg> The ltsp username is a bot, a program that helps in the channel
| |
| 15:10 | <computer_freak_8> oh, okay.
| |
| 15:10 | that makes sense, then.
| |
| 15:10 | <alkisg> It remembers things and we ask it to tell them with the ! in front
| |
| 15:11 | <computer_freak_8> oh, nice!
| |
| 15:11 | that might be my next project... an irc server with a memory bot!

| |
| 15:12 | * computer_freak_8 rolls eyes | |
| 15:13 | <computer_freak_8> okay, so, an interesting issue:
| |
| 15:13 | my chroot does not have a /home/jared folder, and thus no .xsession-errors file.
| |
| 15:13 | <alkisg> Not in the chroot
| |
| 15:13 | In the server
| |
| 15:13 | <computer_freak_8> My server has a /home/jared folder, but not .xsession-errors
| |
| 15:14 | <alkisg> It's hidden
| |
| 15:14 | How did you try to see that file? With some file manager?
| |
| 15:14 | Try with a command: tail /home/jared/.xsession-errors
| |
| 15:14 | <computer_freak_8> http://pastebin.com/8z9vLnks
| |
| 15:14 | does not exist
| |
| 15:14 | <alkisg> Indeed
| |
| 15:15 | Do you have a desktop environment on the server?
| |
| 15:15 | E.g. gnome, kde etc?
| |
| 15:15 | <computer_freak_8> um... good question.
| |
| 15:15 | Yet_another_Bill has left IRC (Yet_another_Bill!~billy@203.114.244.88, Read error: Connection reset by peer) | |
| 15:15 | <computer_freak_8> I didn't specifically install one, but I thought I saw one being installed automatically at some point.

| 15:16 | staffencasa has joined IRC (staffencasa!~staffenca@128-193-145-225.oregonstate.edu) | |
| 15:16 | <alkisg> Which debian version is that?
| |
| 15:17 | Try this, on the server, the main part: dpkg -l gnome-terminal
| |
| 15:17 | <computer_freak_8> none found.
| |
| 15:17 | I'm installing "desktop-base" now.
| |
| 15:18 | this was a real ID 10-T error, I think.
| |
| 15:18 | it would definitely explain why I can't get a desktop session...
| |
| 15:18 | <alkisg> Yup :)
| |
| 15:18 | Hehe first time I saw ID 10-T :D
| |
| 15:19 | <computer_freak_8> I've been using it for a while - I pull them often. :)
| |
| 15:19 | I don't know who came up with that term, though.
| |
| 15:20 | So, I'm a bit confused with the chroot/not-chroot thing: when does it move to the chroot?
| |
| 15:21 | <alkisg> An easy way to think about it is this:
| |
| 15:21 | The chroot is a very small OS that is used to boot the client
| |
| 15:21 | Then the client does a "remote desktop" to the server
| |
| 15:22 | And every program the user runs, it runs on the server
| |
| 15:22 | <computer_freak_8> oh, okay... my thinking was backwards.
| |
| 15:22 | <alkisg> So, where would openoffice, firefox, gnome etc be? In the server or in the chroot?
| |
| 15:22 | <computer_freak_8> server
| |
| 15:22 | <alkisg> Yup. Where would the user accounts be?
| |
| 15:22 | <computer_freak_8> unless you're me, and misconfigure it.
| |
| 15:22 | server
| |
| 15:22 | except root
| |
| 15:22 | <alkisg> Yup, you got it
| |
| 15:22 | <computer_freak_8> it'll be both places
| |
| 15:22 | <alkisg> Not really
| |
| 15:22 | There's an ltsp-build-client switch for that
| |
| 15:22 | --root-pass, I think
| |
| 15:23 | <computer_freak_8> oh, okay.
| |
| 15:23 | <alkisg> If you set that, you enable the root account on the client
| |
| 15:23 | I believe you did that, otherwise you'd be unable to log in as root on the thin client
| |
| 15:23 | <computer_freak_8> I just did a ltsp-update-image, and it only showed one user/uid this time (root), instead of the three it was previously showing.
| |
| 15:24 | okay, so, I'm back to where I started, working-wise, unless my server just needs rebooted.
| |
| 15:24 | So I'm trying that now.

| |
| 19:04 | Ah
| |
| 19:04 | <bakytn> what is LTSP_CONFIG=True?
| |
| 19:04 | <Hyperbyte> SCREEN_DEFAULT does exist, just found it in the source.
| |
| 19:05 | And apparently LTSP_CONFIG=True makes your lts.conf being ignored.

| 19:31 | <computer_freak_8> True, it's not...
| |
| 19:31 | However, the LTSP_CONFIG was there before I edited it.
| |
| 19:32 | I got the SCREEN_DEFAULT from
| |
| 19:32 | !SCREEN_08
| |
| 19:32 | <ltsp> computer_freak_8: SCREEN_08: To get a root shell on a Debian thin client, put SCREEN_07=ldm, SCREEN_08=shell and SCREEN_DEFAULT=07 to lts.conf..
| |
| 19:32 | <Hyperbyte> computer_freak_8, LTSP_CONFIG is not in the default lts.conf.
| |
| 19:32 | <computer_freak_8> I'll comment those out and see what happens.
| |
| 19:32 | <vagrantc> pscheie: 2008. some people were thinking of coming around for oscon, and we tried to piggyback on it... and most people ended up not going to oscon at all, in the end. :)
| |
| 19:32 | <Hyperbyte> Don't comment, remove LTSP_CONFIG=True completely. You don't want it.
| |
| 19:33 | <computer_freak_8> Oh, okay.
| |
| 19:33 | <vagrantc> LTSP_CONFIG=True isn't harmful, unless you want to explicitly set LTSP_CONFIG=False
| |
| 19:33 | <pscheie> hmm, airfare to Portland, OR is not too much more than airfare to Portland, ME.
| |
| 19:33 | <vagrantc> in which case, you'd change the False to true.
| |
| 19:34 | or vice-versa.
| |
| 19:34 | i think i had debian add LTSP_CONFIG=True by default before the bugs were fixed with empty lts.conf
| |
| 19:34 | <computer_freak_8> I'm actually using Debian, so that might have something to do with it.
| |
| 19:35 | Still fail here...
| |
| 19:35 | <vagrantc> whatever you do, don't run ltsp-update-image. it's evil on debian.
| |
| 19:35 | <Hyperbyte> vagrantc, you sure? I just saw in the source that 'LTSP_CONFIG' is set to True once lts.conf is loaded, so it doesn't get loaded twice. Unless I read wrong, that would seem to imply lts.conf won't get loaded?

| |
| 19:39 | which is a file that loads values from lts.conf
| |
| 19:39 | <Hyperbyte> computer_freak_8, what if you enable a root shell on SCREEN_02 and run getltscfg -a ? Does it show your configuration?
| |
| 19:39 | <vagrantc> and then some
| |
| 19:40 | on debian, SCREEN_01-SCREEN_06 are already useed by getty
| |
| 19:40 | use 07+
| |
| 19:40 | <Hyperbyte> I'm gonna kindly butt out of this Debian stuff. :-)
| |
| 19:40 | <computer_freak_8> Eh, I've got a root password, so I can login.
| |
| 19:40 | <vagrantc> computer_freak_8: what are you trying to do again?
| |
| 19:40 | <computer_freak_8> Get my LTSP setup to auto-login.
| |
| 19:40 | I can do it manually, but I'd like it to auto-login with the user: guest and password: pass

| 19:41 | (I might change those later, for security, but for now, those are what I'm working with)
| |
| 19:41 | <vagrantc> computer_freak_8: you need one user per thin client
| |
| 19:41 | <computer_freak_8> Oh...
| |
| 19:41 | I can't have one user, multiple thin clients?
| |
| 19:41 | <vagrantc> not if you want to use the thin clients at the same time :)
| |
| 19:42 | one user, one login. it's due to bugs in many stupidly written programs
| |
| 19:42 | <computer_freak_8> Oh, okay. :)
| |
| 19:42 | <vagrantc> you should be able to do it, but silly things like mozilla prodocuts, openoffice/libreoffice, gnome, etc. all make bad assumptions.
| |
| 19:43 | <computer_freak_8> So, what would I need to do to get it setup properly? Add per-MAC-address configuration of some sort?
| |
| 19:44 | <vagrantc> if you want, or you can configure the autogenerated username/passwords
| |
| 19:45 | defaults to ltsp(some number based on ip address)
| |
| 19:45 | i.e. for a network with 192.168.0.100 ... 192.168.0.250 , it will use ltsp100 ... ltsp250
| |
| 19:45 | password defaults to the same as username
| |
| 19:46 | or you can just set a global password for all the users
| |
| 19:46 | or use ssh keys ... but that's a bit more involved (though my preferred method)
| |
| 19:46 | <computer_freak_8> oh, okay....
| |
| 19:47 | Does it matter that my DHCP server is not the same server as my LTSP server?
| |
| 19:47 | <vagrantc> i prefer to set it to use ssh keys and set up passwordlless accounts, otherwise they can change the password and such
| |
| 19:47 | <computer_freak_8> And how does that work with diskless clients?
| |
| 19:47 | <vagrantc> computer_freak_8: shouldn't be a problem.
| |
| 19:47 | <computer_freak_8> okay
| |
| 19:47 | <vagrantc> computer_freak_8: so, you can log in manually, but autologin isn't working?
| |
| 19:47 | <computer_freak_8> correct
| |
| 19:48 | <vagrantc> and if you put LDM_USERNAME=guest and LDM_PASWORD=pass, and LDM_AUTOLOGIN=true, it doesn't work?
| |
| 19:48 | <computer_freak_8> Correct.
| |
| 19:49 | Then again, might it be the rest of my lts.conf file?
| |
| 19:49 | http://pastebin.com/yJ3guGkN
| |
| 19:49 | <vagrantc> you might try LDM_GUESTLOGIN=true instead of LDM_AUTOLOGIN... and then set SCREEN_07=ldm, SCREEN_08=shell, SCREEN_DEFAULT=07
| |
| 19:49 | <computer_freak_8> Okay, does it matter if it's "True" or "true"?
| |
| 19:50 | <vagrantc> looks fine.
| |
| 19:50 | true/True/tRUe are all the same :)
| |
| 19:50 | <computer_freak_8> Good. I was hoping there wasn't more stupidly written code there. :P
| |
| 19:50 | <vagrantc> though the officially supported are true/True/y/Y, if i remember correctly.
| |
| 19:52 | <computer_freak_8> crap, I've got to go now.
| |
| 19:52 | I'll definitely be back, though.
| |
| 19:53 | Thanks for your help, @vagrantc and @Hyperbyte

| |
| 20:14 | <bakytn> mgariepy, yes
| |
| 20:16 | mgariepy, hereis the contents of /etc/ltsp/accountmanager.conf http://pastebin.com/5nXMdZWZ
| |
| 20:16 | <mgariepy> netstat -puant|grep 8001
| |
| 20:16 | will give you LISTERN <pid>/python

| 20:16 | <bakytn> tcp 0 0 0.0.0.0:8001 0.0.0.0:* LISTEN -

| |
| 20:19 | then type getkey
| |
| 20:20 | <bakytn> returned ssh-rsa and then "closed by foreign host."
| |
| 20:21 | not sure which of the pubkey it returned because the app server pubkey is different
| |
| 20:21 | (ops sorry disregard the last message)
| |
| 20:22 | <mgariepy> on 192.168.1.191
| |
| 20:22 | who is triing to ask getkey to it ?
| |
| 20:22 | the thin client ?
| |
| 20:22 | <bakytn> yes. 192.168.1.191 is the ThinClient device IP (got from DHCP)
| |
| 20:23 | <mgariepy> ok 192.168.1.191 is your loadblancer?
| |
| 20:23 | huh
| |
| 20:23 | <bakytn> the loadbalancer is 192.168.1.239 (the root server)
| |
| 20:24 | 192.168.1.191 is the Thin Client device IP
| |
| 20:25 | <mgariepy> what configuration for LDM_SERVER do you have in ltsp-cluster-control ?
| |
| 20:26 | <bakytn> sorry, where should I see it?
| |
| 20:26 | ah moment
| |
| 20:26 | it is: %LOADBALANCER%
| |
| 20:26 | LDM_SERVER is %LOADBALANCER%
| |
| 20:27 | <mgariepy> ltsp-cluster-lbagent running on your appserv ?
| |
| 20:27 | Gadi has joined IRC (Gadi!~romm@ool-18bbe47a.static.optonline.net) | |
| 20:28 | <bakytn> here is my lbsconfig.xml http://pastebin.com/xTDy023E
| |
| 20:28 | <mgariepy> the problem is that your loadblancer server doesn't have any client in is pool. when the LDM_SERVER config on your thin client is empty it takes the ltsp-root server
| |
| 20:28 | <bakytn> yes lbagent is running
| |
| 20:28 | <mgariepy> on ltsp-root
| |
| 20:28 | ping vserver1-appserver
| |
| 20:28 | 01
| |
| 20:28 | <bakytn> it bings
| |
| 20:28 | pings
| |
| 20:29 | <mgariepy> Cannot retrieve node 'vserver1-appserver01', error:<class 'socket.timeout'>
| |
| 20:29 | <bakytn> yes. that's strange.
| |
| 20:29 | it's in both /etc/hosts
| |
| 20:29 | IP's are valid (double checked)
| |
| 20:30 | so they both can see each other by hostname's
| |
| 20:30 | may be the problem is that so the Thin Client can't resolve the hostname to ip?
| |
| 20:30 | I mean the Thin Client device
| |
| 20:30 | <mgariepy> can you put the ip in lbsconfig.xml in the address field.
| |
| 20:30 | no
| |
| 20:31 | <bakytn> ok moment
| |
| 20:31 | <mgariepy> the thin client doesn't talk to the loadbalancer, and it receive the ip address for the server it needs to connect to.
| |
| 20:31 | <bakytn> ok
| |
| 20:32 | I changed the lbsconfig to use IP address. I need to /etc/init.d/ltsp-cluster-lbserver restart right?
| |
| 20:32 | <mgariepy> is lbagent binded to the port 8000 on the appserv ?
| |
| 20:32 | yeah
| |
| 20:32 | <bakytn> yes it's binded to 8000
| |
| 20:32 | <mgariepy> ok
| |
| 20:32 | <bakytn> let me restart thin client device then?
| |
| 20:33 | <mgariepy> do you see the same error in the /var/log/ltsp-cluster-lbserver.log ?
| |
| 20:34 | <bakytn> the last lines from /var/log/ltsp-cluster-lbserver.log http://pastebin.com/dChJA5gV
| |
| 20:35 | here http://pastebin.com/5nXMdZWZ what does key=PUT-A-KEY-HERE means?

| 20:36 | <mgariepy> wget -q -O - http://192.168.1.239:8008/
| |
| 20:37 | <bakytn> the command you provided is returning: 192.168.1.241
| |
| 20:37 | 192.168.1.241 is an IP of vserver1-appserver01
| |
| 20:37 | <mgariepy> good.
| |
| 20:38 | does your thin client works now ?
| |
| 20:38 | <bakytn> I restarted Thin Client. no result
| |
| 20:38 | <mgariepy> can you run """getltscfg-cluster -a""" on the thin client
| |
| 20:39 | <bakytn> I need to SCREEN_02=shell (one moment)

| |
| 21:46 | <alkisg> Sure
| |
| 21:46 | That's how packages create menus
| |
| 21:47 | <shawnp0wers> Do they create menus, or conform to the freedesktop already-existing-menu structure?

| |
| 21:48 | <shawnp0wers> I'll go peek at some .desktop files and see if I can make something work

| 23:42 | <bakytn> nroussi, cna you set default gateway for eth1?
| |
| 23:42 | route add default gw <gw_ip> eth1
| |
| 23:43 | <markit> btw, b) solved, is a bug of the script http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635086
| |
| 23:45 | <bakytn> markit, what does "can't open 2 sessions in the clients" means? you can't launch two thin clients?
| |
| 23:45 | <markit> bakytn: in K menu, when I enter the "leave" menu, I have "switch user" option
| |
| 23:46 | since there are 2 children for each pc, would love to be able to switch user on the fly
| |
| 23:46 | btw, I had the LDM_LIMIT_ONE_SESSION=true, now I've set to false and restarted the client
| |
| 23:47 | do I have to reboot the server too? (the "M$ way" ;P))
| |
| 23:51 | <bakytn> markit, I suppose "switch user" option is not applicable in LTSP environment
| |
| 23:51 | <nroussi> baktyn, I added the route. I cant test it now but my issuing a route command gives me this http://pastebin.com/2iPEfmRf
| |
| 23:52 | <bakytn> markit, when you change lts.conf you dn't have to reboot the server nor update the image
| |
| 23:52 | markit, you would probably have to reboot your thin client
| |
| 23:54 | nroussi, can you ping 192.168.2.100 ?
| |
| 23:56 | <nroussi> bakytn, when I ssh into the server from the LAN and I go into the chroot environment I can ping anything. From the clients though I cannot
| |
| 23:56 | <markit> bakytn: sure, client rebooted but the option seems ignored (or seem to work like "lock screen" instead)
| |
| 23:58 | <bakytn> markit, I think, not sure, that it's impossible to just swithc the users keeping previous session active. You have to logout first and then log in as a different user
| |
| 23:58 | nroussi, can you run ifconfig -a in clients?
| |
| 23:58 | <markit> bakytn: ok, I thought was technically difficoult in fact...
| |
| 23:58 | my last and biggest problem is now keyboard
| |
| 23:58 | wondering if is a fault in detecting it, or whatever
| |
| 23:59 | <bakytn> markit, I never had problems with keyboards in 11.04. Do you have any keyboard related settings in lts.conf? if yes, can you comment them out and try again?
| |
| 23:59 | <nroussi> bakytn: yes let me go on a client to give you the output
