| 00:02 | <slashdotfx> cyberorg: I've configured the session to be autologin
| |
| 00:02 | <cyberorg> slashdotfx, that variable should help ^^
| |
| 00:02 | <slashdotfx> will that variable help kills the previous processes?

| 00:15 | <slashdotfx> ok, I see that there is this LDM_LIMIT_ONE_SESSION_PROMPT variable too
| |
| 00:16 | I'm setting it to False
| |
| 00:16 | it should kill the previous stale process without a prompt, I hope
| |
| 00:20 | <cyberorg> set it to true

| 06:24 | <maginot> Ioctl/1.1a failed: Bad File discriptor and in the other console "que, disconnect, sock, done" ... and this wasnt happening before I copy the /lib /boot from new client build to the old working build (some tweaks to try to solve the client printing problem - worked.)
| |
| 06:29 | <slashdotfx> cyberorg: which one should I set to true?
| |
| 06:30 | I've thought (after reading S15-userLoginCheck) LDM_LIMIT_ONE_SESSION_PROMPT should be true
| |
| 06:31 | kill stale processes without prompting user
| |
| 06:31 | <cyberorg> slashdotfx, exactly
| |
| 06:32 | <slashdotfx> will it work if I set LDM_DIRECTX to true also?
| |
| 06:33 | <cyberorg> yes it should
| |
| 06:33 | but why don't you just go ahead and try it out yourself :)
| |
| 06:34 | <slashdotfx> I already did, and just about a few minutes a go, I get into trouble with some client
| |
| 06:34 | all the sudden the dialog box prompt showed up
| |
| 06:35 | in the middle of client session, after running a couple of minutes
| |
| 06:48 | <maginot> and the other issue seens to be with libc, some files in openoffice are crashing
| |
| 06:54 | mamboloco has joined #ltsp | |
| 06:57 | <maginot> ok, this question is simple, witch folder/files the client setup reads from /etc ?
| |
| 06:57 | (in the boot time)
| |
| 06:58 | which files it read from its chroot /etc on boot time (better this way)

| 06:59 | intelliant_ has joined #ltsp | |
| 07:00 | <slashdotfx> plenty
| |
| 07:00 | I mean a lot
| |
| 07:01 | <maginot> Hmmm
| |
| 07:02 | slashdotfx, well, I know that my Ioctl problem above is related with somewhere in /etc when I copy back from the old /etc config the client boots without problem. I just need to know which files to copy back =/
| |
| 07:05 | carniel has joined #ltsp | |
| 07:05 | <maginot> wekk
| |
| 07:05 | <slashdotfx> did you mean /etc under /opt/ltsp/<arch> ?
| |
| 07:05 | <maginot> the problem is inside udev/
| |
| 07:05 | <slashdotfx> as in chroot /etc ?
| |
| 07:05 | <maginot> yep
| |
| 07:06 | the problem related with Ioctl above is inside udev copying udev/ from backuped etc make client boot up again

| |
| 07:38 | <ltspbot> alkisg: Error: "distro" is not a valid command.
| |
| 07:38 | <alkisg> !dist
| |
| 07:38 | <ltspbot> alkisg: "release" is please mention the linux distro and release you're using :)
| |
| 07:38 | <alkisg> tadeu_: ^^^
| |
| 07:39 | 8.10?
| |
| 07:39 | <tadeu_> ubuntu
| |
| 07:39 | yup
| |
| 07:39 | <alkisg> You also need CONFIGURE_X=true for every X** directive in lts.conf
| |
| 07:39 | otherwise they're ignored
| |
| 07:40 | so, you could e.g. try with CONFIGURE_X=true and XSERVER=vesa
| |
| 07:40 | <tadeu_> alkisg, thanks... so i just need CONFIGURE_X=true XSERVER = auto
| |
| 07:40 | alkisg, ok thank you
| |
| 07:40 | <alkisg> tadeu_: I think XSERVER=auto is implied, isn't it?
| |
| 07:41 | <tadeu_> alkisg, not sure, but makes sense
| |
| 07:42 | carniel has quit IRC | |
| 07:42 | <tadeu_> alkisg, thanks any way.. i'll test your suggest

| 08:09 | <X-TaZ> Hi there
| |
| 08:09 | Does someone here uses gnome-watchdog ?
| |
| 08:10 | <tadeu_> alkisg, it worked fine.. thanks
| |
| 08:11 | <alkisg> tadeu_: in general, vesa has lower performance than your cards driver, so if performance is an issue, maybe you could try some debugging to pinpoint the problem
| |
| 08:11 | <X-TaZ> I've installed it following https://help.ubuntu.com/community/UbuntuLTSP/GnomeWatchdog but I don't know how to launch it :x
| |
| 08:12 | otavio has joined #ltsp | |
| 08:12 | <slashdotfx> argh, the ltsp server just freeze
| |
| 08:14 | <tadeu_> alkisg, in fact i had some problems using just XDMCP the problem was the network traffic
| |
| 08:14 | alkisg, as i can see, LTSP i better in this point
| |
| 08:15 | <alkisg> Yeah by default it uses SSH -X which also compresses the traffic. Needs more CPU, though
| |
| 08:15 | <slashdotfx> X-TaZ: it should be automatically, check if there is startup script installed under /etc/X11/Xsession.d
| |
| 08:16 | btw, I'm using xterminator, but stop working on jaunty
| |
| 08:17 | <tadeu_> alkisg, in my case i have a Quad Core with 4GB RAM... my limitation is network, that's why i'm digging solutions to speed up the network traffic
| |
| 08:18 | alkisg, if you have any documentation about that..
| |
| 08:18 | <alkisg> Why, don't you have a 1Gb port on the switch?
| |
| 08:18 | <X-TaZ> thx slashdotfx : does watchdog gives a graphical interface ?
| |
| 08:19 | ( and yes there is a Xsession.d :)
| |
| 08:19 | <slashdotfx> X-TaZ: gnome-watchdog uses gtkdialog according to the wiki
| |
| 08:20 | <tadeu_> alkisg, yes, we have, but in this moment the cable and server nic is 100
| |
| 08:20 | <X-TaZ> Ok.. well it dont works
| |
| 08:20 | <alkisg> tadeu_: a 1Gb nic for the server is 8 euros - don't waste your time without it :)
| |
| 08:20 | jammcq has joined #ltsp | |
| 08:20 | <X-TaZ> ** ERROR **: GtkDialog: Could not find the dialog description in the environment variable 'MAIN_DIALOG'.
| |
| 08:21 | <alkisg> tadeu_: a quad core with 4 mb ram isn't enough for 10 clients on youtube with LDM_DIRECT=false :)
| |
| 08:21 | <slashdotfx> sorry, I didn't use gnome-watchdog
| |
| 08:21 | <X-TaZ> Ok
| |
| 08:21 | <tadeu_> alkisg, =)
| |
| 08:21 | <slashdotfx> I just assume gnome-watchdog use the same method as xterminator
| |
| 08:21 | <tadeu_> alkisg, tell a thing..
| |
| 08:22 | <slashdotfx> just today, I was looking for a way how to kill stale processes from previous session
| |
| 08:22 | <tadeu_> alkisg, if i put a 1GB nic and keep the calbe (100)... it would increase the performance ? considering the higher nic cache or what else
| |
| 08:22 | <slashdotfx> and cyberorg tells me to use LDM_LIMIT_ONE_SESSION in lts.conf
| |
| 08:23 | <X-TaZ> And does it solve , slashdotfx ?
| |
| 08:24 | <alkisg> tadeu_: afaik, it'll either synchronize at 1000mbps or at 100mbps - depending on the length and quality of the cable - I don't have much experience on this, though...
| |
| 08:24 | <slashdotfx> apparently I hadn't had the time to check it thoroughly
| |
| 08:24 | since the workstation is currently used by users
| |
| 08:24 | <alkisg> tadeu_: for 5m length cables at my school the server nic syncs at 1Gb with no problem
| |
| 08:25 | <X-TaZ> I got experience in it, I'm student in networking and telecommunications : all depens on the Cat of your cable
| |
| 08:25 | Cat 5, 5e .. 6
| |
| 08:25 | <tadeu_> X-TaZ, yeah.. right now it is 5
| |
| 08:25 | <slashdotfx> to test it, my method is simple, each time the desktop showed up (autologin), I press the reset button
| |
| 08:26 | <tadeu_> X-TaZ, what do you think about have a cat5 cable with 1GB nic
| |
| 08:26 | <X-TaZ> Well, its possible it sync at 1Gbps, how long calbe do you have ?
| |
| 08:27 | <tadeu_> X-TaZ, about 10m
| |
| 08:27 | <X-TaZ> I believe it should sync a 1Gbps full duplex :)
| |
| 08:27 | <tadeu_> X-TaZ, even a cat5 ?
| |
| 08:28 | <X-TaZ> Yes. It works at school wth 15m cat5
| |
| 08:28 | <tadeu_> X-TaZ, nice
| |
| 08:28 | <X-TaZ> But we get a bit more packet loss when we get +800mbps or more
| |
| 08:29 | <tadeu_> X-TaZ, how many clients ?
| |
| 08:29 | X-TaZ, just for curiosity
| |
| 08:29 | <X-TaZ> Its not for ltsp we use it
| |
| 08:30 | We test it between routers for practical school works :)
| |
| 08:30 | We dont use ltsp at my school. I use it in the enterprise i'm working right now ...

| 08:47 | <jammcq> Gadi?
| |
| 08:48 | <Gadi> morning
| |
| 08:48 | <ogra> jrock2004, create an /etc/ltsp/nbdswapd.conf file on the server
| |
| 08:48 | <jammcq> hey, how's it goin?
| |
| 08:48 | <Gadi> can't complain
| |
| 08:48 | what'd I miss?
| |
| 08:48 | :)
| |
| 08:48 | <ogra> jrock2004, SIZE=64
| |
| 08:48 | <jammcq> umm, dunno, have you been gone?
| |
| 08:48 | <ogra> add that
| |
| 08:48 | <Gadi> hehe
| |
| 08:48 | jammcq: how you been?
| |
| 08:48 | <jammcq> been great, as always
| |
| 08:49 | <Gadi> heard a story on the radio of a guy in Michigan who didnt know his wife was pregnant until she was giving birth in the bathtub
| |
| 08:49 | you guys are crazy over there
| |
| 08:49 | <jammcq> yeah, sounds about right
| |
| 08:49 | <Gadi> :)

| 09:09 | <tadeu_> guys, still about net work traffic, what about using NETWORK_COMPRESSION=true ?
| |
| 09:09 | the default is unset
| |
| 09:12 | <jrock2004> ogra: Do I have to set anything in the lts.conf
| |
| 09:12 | <ogra> no
| |
| 09:13 | nbdswapd creates the swapfiles if the clients connect
| |
| 09:13 | <rjune> !o
| |
| 09:13 | <ltspbot> rjune: Error: "o" is not a valid command.
| |
| 09:13 | <jrock2004> ogra: ok cool stuff I just checked the tmp directory and there is a 64MB file in there
| |
| 09:13 | <ogra> have a look inside the nbdswapd script there are some more vars you can change
| |
| 09:14 | <rjune> ogra, howdy, been a while
| |
| 09:14 | <ogra> i.e. if your server has enough spare ram, try to create the swapfiles in a tmpfs ;)
| |
| 09:14 | hey rjune
| |
| 09:15 | busy busy busy ... getting the ubuntu ARM world in shape
| |
| 09:15 | but Rc was released yesterday so i can slow down a bit after nearly three weeks without sleep
| |
| 09:15 | <rjune> cool deal
| |
| 09:16 | I got an OpenMoko phone
| |
| 09:16 | <ogra> heh, the HW i work with/for has 800MHz/512M :)
| |
| 09:16 | <rjune> yeah I know
| |
| 09:16 | X-TaZ has quit IRC | |
| 09:17 | <vagrantc> tadeu_: haven't seen reports of NETWORK_COMPRESSION actually benefiting much, if anything, and some reports that it actually slows down the connections
| |
| 09:17 | <ogra> openmoko isnt really my target ...
| |
| 09:17 | <rjune> I'm aware ogra.
| |
| 09:17 | It wasn't mine either. I had one fall into my lap
| |
| 09:17 | <ogra> heh
| |
| 09:21 | <tadeu_> vagrantc, well, i have about 15 clients.. really don't if it really necessary, especially considering your review
| |
| 09:23 | <vagrantc> doesn't even look like the current code supports it
