| 02:37 | <muppis> Is there remote reboot thin? (My brains are still in sickleave..)
| |
| 02:41 | <alkisg> By default no, but there are ways to enable that
| |
| 02:41 | If the user is logged in, you can reboot it though, yes
| |
| 02:41 | <muppis> How is that done?
| |
| 02:43 | <alkisg> It needs 4-5 commands, to get the user session, set an xprop and call gnome logout...
| |
| 02:43 | <muppis> Ah.. Now I recall. Well, I send email to customer and requst it to do locally.
| |
| 02:44 | <alkisg> What exactly do you need? To be able to reboot any pc at any given time?
| |
| 02:44 | If it's just for once, yeah that'd be faster :)
| |
| 02:45 | <muppis> I mistyped mac in dhcpd.conf and it didn't get correct IP, so cannot install printer.. :D

| 06:16 | <muppis> Nice one. How I managed two mistypes for mac in dhcpd.conf..
| |
| 06:18 | * Hyperbyte smacks muppis | |
| 06:18 | <Hyperbyte> How could you!
| |
| 06:18 | <muppis> Shame on me.
| |
| 06:18 | <Hyperbyte> :)
| |
| 06:19 | Though, you could twist it around and say mac address needs to be changed. ;-)
| |
| 06:19 | That'd be the American way of covering up mistakes. ;-)

| 06:20 | otavio has joined #ltsp | |
| 06:22 | <muppis> Heh.. Well, I can say I made mistake, even that American way makes more chargeable.
| |
| 06:23 | <Hyperbyte> I was being sarcastic. :)
| |
| 06:23 | <muppis> I noticed. :)
| |
| 06:23 | <Hyperbyte> Thought that with all the going-ons with WikiLeaks I could throw in a little joke there.
| |
| 06:23 | Hehe
| |
| 06:24 | <muppis> :D
| |
| 06:31 | Ah.. My life got easier. I struggled with dhpcd and pxe home. Somehow my wlan router, which I used for dhcpd and firewall etc, didn't manage well if dhcpd was elsewhere in lan. Switched it to dd-wrt based wlan router and it uses DNSMasq for dhcpd and dns.. :)
| |
| 06:31 | at home..
| |
| 06:32 | <alkisg> !xauthority

| |
| 06:33 | <muppis> alkisg, copypasting?
| |
| 06:33 | <alkisg> Yup :)
| |
| 06:33 | <muppis> :)
| |
| 06:34 | <alkisg> ltspbot is very handy
| |
| 06:34 | <ltspbot> alkisg: Error: "is" is not a valid command.
| |
| 06:36 | <muppis> Looks like it.
| |
| 06:38 | Oh my.. Upgrading servers has took all afternoon.. Freak.
| |
| 06:38 | Remaille has joined #ltsp | |
| 06:39 | <muppis> 16 so far, still 8 to go.
| |
| 06:59 | <Hyperbyte> :)
| |
| 06:59 | Looks we're somewhat in the same barrel today muppis. :P
| |
| 06:59 | * Hyperbyte is installing a new server | |
| 06:59 | <muppis> :D
| |
| 07:22 | <Hyperbyte> Heh... the server I was working on accidentally did a PXE boot... which leads to LTSP on the network
| |
| 07:23 | Server Opteron processor, raid harddisks...
| |
| 07:23 | It froze while loading LTSP. :O

| 09:44 | <ninou> hi
| |
| 09:46 | i upgrade my ltsp server to ubuntu 10.04 but it does not work on my old gx260 dell. The Xserver always restart, i try to log in console ctrl-alt-f1, but i can not work because the x server always try to restart. how can i stop it.
| |
| 09:47 | <alkisg> What graphics card does it have?
| |
| 09:47 | !SCREEN_02
| |
| 09:47 | <ltspbot> alkisg: "SCREEN_02" :: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN
| |
| 09:47 | <ninou> Intel(R) 82845G/GL/GE/PE/GV Graphics Controller
| |
| 09:47 | <alkisg> Ouch
| |
| 09:48 | When 10.04 was released I had to use a kernel from a ppa to use my 82855
| |
| 09:49 | If the situation hasn't changed, and 845 is similar to 855, then you're into problems :(
| |
| 09:49 | I think in maverick they're using fb instead of intel drivers for those cards
| |
| 09:50 | <ninou> so i have to downgrade to ubuntu 8.04, because it works in this version
| |
| 09:50 | <alkisg> No, better upgrade to 10.10
| |
| 09:50 | Wait I'll give you a link with some things to try
| |
| 09:50 | <ninou> thanks
| |
| 09:51 | <alkisg> https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes
| |
| 09:51 | There are some notes there that say to try nomodeset etc
| |
| 09:51 | You can try those in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
| 09:52 | <ninou> ok i try

| |
| 10:11 | <komunista> alkisg: hi
| |
| 10:11 | alkisg: I get crash today from FF
| |
| 10:12 | in on image (by on client), I try to get some info, but when I try reproduce this 5x, only one crash happen
| |
| 10:13 | but while it, I see growing the amount of the used RAM, but not the buffers and cache
| |
| 10:14 | ninou has left #ltsp | |
| 10:16 | <alkisg> komunista: right, pixmaps are not in cache
| |
| 10:19 | staffencasa has joined #ltsp | |
| 10:20 | <komunista> alkisg: but why I cannot reproduce it?
| |
| 10:28 | <alkisg> No idea, are you visiting the same site?
| |
| 10:31 | <komunista> the same image
| |
| 10:32 | on the same site :-)

| 11:40 | <knipwim> anyone experience with a hp t5710 and ltsp?
| |
| 11:42 | MorningSon has joined #ltsp | |
| 11:43 | <Appiah> yupp
| |
| 11:43 | <knipwim> succesfull?
| |
| 11:45 | <Appiah> sure
| |
| 11:45 | why not? :)
| |
| 11:45 | they have very little ram
| |
| 11:45 | but they work
| |
| 11:46 | <alkisg> I think "nomodeset" is needed in pxelinux.cfg/default for their ati cards to work ok...
| |
| 11:47 | <knipwim> i was wondering about the soundcard
| |
| 11:47 | apparently the intel8x0 driver is used
| |
| 11:47 | <Appiah> alkisg: I have not touched the pxelinux.cfg/default
| |
| 11:47 | <knipwim> but i saw little successtories in the web
| |
| 11:47 | <Appiah> what dist and version?
| |
| 11:47 | knipwim: where?
| |
| 11:48 | <knipwim> gentoo on ltsp5.2.5
| |
| 11:48 | <Appiah> I have not used gentoo for a long time
| |
| 11:48 | <knipwim> thinking of buying one
| |
| 11:48 | <Appiah> but sound works wihout anything extra needed on ubuntu
| |
| 11:48 | <knipwim> gentoo shouldn't be a problem
| |
| 11:48 | <Appiah> buying a T5710?? Can you still find one?
| |
| 11:49 | <knipwim> secondhand
| |
| 11:49 | <Appiah> ah
| |
| 11:49 | <knipwim> 100 euros
| |
| 11:49 | or am i being ripped off then :)
| |
| 11:49 | <Appiah> well I've seen T5710 work
| |
| 11:49 | My first customer who I helped with LTSP was a school that mostly had those
| |
| 11:49 | still works
| |
| 11:50 | <alkisg> Ah sorry I didn't remember correctly, the problem with t5710 that a user had was "inverted screen" (because of nvidia drivers on the server), solved by disabling compiz.

| 11:50 | coordinador has joined #ltsp | |
| 11:50 | <coordinador> hi
| |
| 11:50 | help pĺease! i have 20mins to fix it!!!
| |
| 11:50 | <Appiah> 19:50
| |
| 11:50 | <coordinador> i got "mounting /dev/nbd0 on /rofs failed: invalid argument"
| |
| 11:50 | and many similar errors while booting
| |
| 11:51 | <Appiah> Dist coordinador ?
| |
| 11:51 | <coordinador> (the boxes)
| |
| 11:51 | ubuntu 10.04
| |
| 11:51 | <Appiah> new install?
| |
| 11:51 | <coordinador> updating from 9.10
| |
| 11:51 | worked fine
| |
| 11:51 | <alkisg> When/how did it break?
| |
| 11:51 | <knipwim> Appiah: thanks, definitely buying one
| |
| 11:51 | <coordinador> updating from 9.10
| |
| 11:51 | <alkisg> Ah, it worked in 9.10, but it never worked in 10.04?
| |
| 11:52 | <coordinador> after reboot server, i got this errors
| |
| 11:52 | <alkisg> Did you rebuild the chroot?
| |
| 11:52 | I.e. did you run ltsp-build-client after the update?
| |
| 11:52 | <coordinador> alkisg, im afraid of do that because i installed many localapps
| |
| 11:52 | <alkisg> Urm. So you want to use 9.10 on the chroot but 10.04 in the server, and solve the problem in 20' ?
| |
| 11:52 | <coordinador> last error says "no init found. Try passing init= bootarg."
| |
| 11:53 | <alkisg> (17'... :))
| |
| 11:53 | <coordinador> and finally i got a busybox prompt
| |
| 11:53 | <alkisg> Can you try this in the busybox prompt? nbd-client 1.2.3.4 2000 /dev/nbd0
| |
| 11:53 | (server ip there)
| |
| 11:53 | <coordinador> in 1.2.3.4 goes server ip?
| |
| 11:54 | <alkisg> yup
| |
| 11:54 | <coordinador> ok
| |
| 11:55 | i got many lines saying "nbd0: Attempted send on closed socket"
| |
| 11:55 | and "end_request: I/0 error, dev nbd0, sector 0
| |
| 11:55 | <alkisg> Hmmm is your server listening on 2000?
| |
| 11:55 | grep nbd /etc/inetd.conf
| |
| 11:56 | <coordinador> 2000 stream tcp nowait...
| |
| 11:56 | 9572 stream tcp nowait..
| |
| 11:56 | only two lines
| |
| 11:56 | <alkisg> grep nbd /var/log/daemon.log
| |
| 11:56 | Dec 20 14:32:44 alkis nbd_server[5775]: connect from 10.160.31.16, assigned file is /opt/ltsp/images/i386.img
| |
| 11:56 | <coordinador> i got many many lines
| |
| 11:57 | <alkisg> Do you see something like the above line? ^
| |
| 11:57 | <coordinador> yes. like 10 lines similar
| |
| 11:57 | <alkisg> And any reason for disconnect?
| |
| 11:57 | <coordinador> Dec 20 14:55:01 clases nbd_server[2051]: connect from 192.168.0.37, assigned file is /opt/ltsp/images/i386.img
| |
| 11:57 | <alkisg> Paastebin the last lines there, that show the connection you just tried from busybox
| |
| 11:58 | Or paste them here if they are a few...
| |
| 11:58 | <coordinador> last line says: Read failed: Inappropriate ioctl for device
| |
| 11:58 | and the previous line says: Size of exported file/device is 857636864
| |
| 11:59 | <alkisg> Hmmm the nbd client versions are different in 9.10 from 10.04...
| |
| 12:00 | <coordinador> what about if i just rebuild /opt/ltsp/i386 directory?
| |
| 12:00 | <alkisg> I hope nothing serious changed between them
| |
| 12:00 | That's what ltsp-build-client does, and you lose all your localapps
| |
| 12:00 | <coordinador> ok dont care its kind of urgent
| |
| 12:00 | lusers will use few progs xD
| |
| 12:00 | <alkisg> It takes more than 11 minutes :)
| |
| 12:00 | <coordinador> :O
| |
| 12:00 | <alkisg> sudo mv /opt/ltsp /opt/ltsp-9.10
| |
| 12:00 | sudo ltsp-build-client
| |
| 12:00 | ...and wait until it completes :)
| |
| 12:00 | <coordinador> :) thank you very much, i will do now
| |
| 12:00 | doing it...
| |
| 12:01 | omg im doing it :S:S
| |
| 12:01 | omg im so scared, people is starting to comig
| |
| 12:02 | *coming
| |
| 12:02 | <alkisg> Timed on a 2 mbps adsl line, it took 20 minutes
| |
| 12:02 | <coordinador> i have like 10mbps (in theory)
| |
| 12:02 | <alkisg> Cross your fingers :)
| |
| 12:02 | <coordinador> ill use only little words to chat, so i use less broadband
| |
| 12:03 | lol
| |
| 12:03 | <alkisg> hhehe
| |
| 12:03 | <coordinador> so after that it should work?
| |
| 12:03 | <alkisg> Well it's supposed to, but you know, problems happen, especially when you don't want them :)
| |
| 12:06 | <coordinador> omg it goes at "libslang2"
| |
| 12:06 | ,X,,
| |
| 12:06 | this is a classroom in a train
| |
| 12:06 | everyday train comes here, to a poor population without economical resources, and at 19.00 the train goes back
| |
| 12:07 | "retrieving perl"
| |
| 12:07 | still waiting...
| |
| 12:08 | Specifically, which is the cause of this error?
| |
| 12:08 | (the error that i had, related to nbd)
| |
| 12:10 | <alkisg> No idea, I'm suspecting nbd-server/nbd-client version mismatch, but I don't think it's too likely..
| |
| 12:11 | <coordinador> ok thank you
| |
| 12:12 | <alkisg> You chose a bad time to upgrade, with little time to fix possible problems :)
| |
| 12:15 | <coordinador> im so afraid now because people is sitting in their chairs andomg still unpacking im about to crying
| |
| 12:16 | after this command , do i have to use another?
| |
| 12:16 | like ltsp update kernerls or some?
| |
| 12:17 | <alkisg> No
| |
| 12:17 | When it finishes you supposedly just boot the pcs
| |
| 12:17 | <coordinador> alkisg, ok thank you very much! omg started to download more things :S

| |
| 14:15 | abeehc_ is now known as abeehc | |
| 14:16 | <abeehc> i woudl guess ffmpeg might
| |
| 14:18 | <robehend1> hmm illl give that a try. I'm just throwing them into PiTiVi right now, and exporting em as a project. I have no clue what format it will do that in though

| 17:17 | <vagrantc> yay. i finally figured out a workaround for LXDE shutdown/reboot problems introduced in debian squeeze
| |
| 17:17 | for some reason, it requires hal to be installed
| |
| 17:17 | and then the LTSP shutdown works!
| |
| 17:18 | so LXDE is still the only environment that properly supports LTSP shutdown/reboot for thin clients :)
