16:28 <mynis> hey guys, i'm trying to get LHC@home working on a debian and everything goes well until the vm starts, then it just crashes

16:28 <mynis> if i run the vm without using the manager then it runs fine

16:29 <mynis> the last thing it says usually before it crashes is "initializing drivers" but sometimes it makes it past that and starts mounting file systems momentarily

16:42 <dango_> some X drivers fails?

16:47 <mynis> yeah i'm trying to figure out what the issue is, right now i'm trying to run it on another debian install i had that has vdpau and cuda and everything configured to see if that fixes it, so far so good

16:49 <mynis> i also switched it to the boinc version in the debian repos instead of the one that you download from the project web site

16:59 <K`Tetch> KTetch waves hey yoyo

17:00 <K`Tetch> ok, just added esti@home to my boinc manager, getting "Communication defered 02:24:37" that normal?

17:01 <yoyo[RKN]> seti has problems

17:01 <K`Tetch> *facepalm*

17:03 <yoyo[RKN]> add yoyo@home, this works ;)

17:03 <K`Tetch> how am I supposed to compare Muon1 with seti@home, if seti@home doesn't work!

17:04 <yoyo[RKN]> regarding what do you want to compare both?

17:05 <K`Tetch> It's for my Dragon*Con panel, whose subtitle is "Forget hunting for primes or alien-spotting. See how genetic-based distributed computing can beat brute-force methods"

17:07 <K`Tetch> so... seti@home is offline for now?

17:07 <yoyo[RKN]> don't know exactly

17:07 *** Aeternus has joined #boinc

17:08 <yoyo[RKN]> just read, that users have probems currently

17:46 <SgrA> When I start boinc on command line, it shows 11-Aug-2011 03:16:11 [---] ATI GPU 0: ATI Radeon HD5x00 series (Cedar) (CAL version 1.4.1353, 1024MB, 104 GFLOPS peak)

17:46 <SgrA> but the graphical client (boincmgr) says Thu 11 Aug 2011 02:36:27 AM ISTNo usable GPUs found

17:48 *** ntat has joined #boinc

17:48 *** Edgeman has joined #boinc

17:49 <whynot> SgrA: aren't you starbing boinccmd as root (or something, what starts boinc later) and boincmgr (what starts boinc later) as regular user with no privileges?

17:50 <SgrA> I ran boinc as user too.

17:51 <whynot> your operating system?

17:51 <SgrA> Arch Linux

17:53 *** ntat has quit IRC

17:57 <whynot> SgrA: can you show output of this: ps l `pgrep boinc`

17:58 <SgrA> F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND

17:58 <SgrA> 1  1001   920     1  39  19  88924 14300 poll_s SNs  ?          1:20 /usr/bin/boinc_client --daemon --dir /var/lib/boinc --redirectio

18:00 <whynot> that's you started with boincmgr, can you show the same when boinc is started from commandline

18:01 <SgrA> http://paste.pound-python.org/show/10835/

18:01 <Romulus> Title: Paste #10835 | LodgeIt! (at paste.pound-python.org)

18:02 <whynot> that's interesting, and does it start at all ever?

18:02 <SgrA> It works normally.

18:06 <whynot> as you can see, boincmgr starts boinc_client

18:06 <SgrA> boinc_client is started as a daemon at boot

18:06 <whynot> in contrary, you've starting boinc

18:06 <SgrA> /etc/rc.d/boinc:

18:06 <SgrA> ...

18:06 <whynot> wait, when you've started boinc was boinc_client running?

18:07 <SgrA> yep

18:07 <whynot> I'm running regular package of debian, thus I could miss something

18:07 <whynot> however, I believe, your home has been filled with boinc files now

18:08 <SgrA> only 154 M

18:08 <SgrA> MB

18:09 <whynot> ok, let's make it clear

18:09 <whynot> when you run boincmgr you dont' actually start anything

18:09 <whynot> boincmgr just connects to already running boinc_client

18:09 <SgrA> i know.

18:09 <SgrA> the boint is, why does boinc_client not accept the available GPU?

18:10 <whynot> I believe, it's a permission problem

18:10 <SgrA> it is started as user `boinc' by the initscript

18:11 <whynot> boinc_client (started the regular way) has no way to access video hardware

18:11 <SgrA> so it must be started as root?

18:11 <SgrA> D:

18:11 <whynot> kind of

18:11 <SgrA> well, I think it should work if I add boinc to some group?

18:12 <SgrA> or start it as my user in the initscript?

18:12 <whynot> wait

18:12 <whynot> in debian there're various groups to allow users or daemons to access something

18:12 <whynot> can you output of this: id

18:13 <whynot> s/you output/you show output/

18:13 <SgrA> uid=1000(sgra) gid=1000(sgra) groups=1000(sgra),92(audio),108(vboxusers)

18:14 <whynot> can you pastebin your /etc/group

18:14 <SgrA> video:x:91:

18:14 <SgrA> That's one line in there which I found intersting.

18:14 <whynot> looks like the way debian does it

18:15 <whynot> ok, add your boinc user (I believe there should be such) to video group

18:15 <SgrA> :)

18:15 <whynot> anyway you can always fall back to running it as root

18:15 <desti> http://science.nasa.gov/science-news/science-at-nasa/2011/09aug_perseids2011/

18:15 <Romulus> <http://tinyurl.com/3ldzpef> (at science.nasa.gov)

18:15 <SgrA> ]# gpasswd -a boinc video

18:15 <SgrA> Adding user boinc to group video

18:16 <SgrA> restart the service ? :)

18:16 <whynot> then restart boinc service (I don't know Arch way of doing this)

18:16 <whynot> hivemind!

18:17 <K`Tetch_> ok, still got my boinc issue - http://dl.dropbox.com/u/12594568/setiagome-boinc-issues.jpg

18:17 <Romulus> <http://tinyurl.com/3jmv4r3> (at dl.dropbox.com)

18:30 <SgrA> 3128 floating MIPS = 3128 MFlops = 3.128 GFlops ?

18:31 <whynot> so it's working now?

18:31 <SgrA> nope :/

18:32 <whynot> it reports, but there's no applications for this hardware?

18:32 <SgrA> no, it doesn't report

18:33 <whynot> I've meant, does boinc_client sees GPU now?

18:34 <SgrA> when I run as root (manually) it does, but as boinc: Another instance of BOINC is running.

18:38 <whynot> either there is another instance or there is a stale lockfile that couldn't be removed as boinc user

18:39 <whynot> in latter case such lockfile has been put as root

18:39 <SgrA> what's the path of the lockfile?

18:39 <whynot> /path/to/boinchome/lockfile

18:40 <whynot> how many instances of boinc are running right now?

18:42 <whynot> there's also /var/run/boinc.pid or something probably

18:44 <SgrA> none

18:45 <whynot> which one is missing?

18:45 <SgrA> I got rid of lockfile but that doesn't fix this Another instance of BOINC is running.

18:45 <whynot> does that shows any numbers: pgrep boinc

18:45 <SgrA> there's no boinc.pid

18:46 <SgrA> nope

18:46 <SgrA> (PIDs instead of numbers is okay with me) :)

18:46 <whynot> yeah, sorry

18:47 <whynot> ok, then clearly there's no instance that could interfere

18:47 <SgrA> yep

18:47 <SgrA> however, this would like to believe that there is. :<

18:48 <whynot> thus, I believe, boinc (as boinc user) tries to acquire lock, fails and just says what it says

18:48 <whynot> probably, it's time to give up and run boinc as root, agreed?

18:49 <SgrA> D:

18:49 * SgrA can't do that after all those lectures on Linux. :P

18:49 *** stux|RC-only has joined #boinc

18:50 <whynot> supposing the path to executable is /usr/bin/boinc_client

18:50 <SgrA> it is.

18:51 <whynot> we are mangling the one that's actual client

18:51 <whynot> chmod 04755 /usr/bin/boinc_client

18:51 <whynot> check it with: ls -l /usr/bin/boinc_client

18:52 <whynot> note -rwsr-xr-x instead of -rwxr-xr-x

18:52 <whynot> then restart service

18:54 <SgrA> hmm it doesn't go work

18:54 <whynot> what's the output?

18:54 <SgrA> # chmod 04755 /usr/bin/boinc_client

18:54 <SgrA> [root@arneb]# ls -l /usr/bin/boinc

18:54 <SgrA> -rwsr-xr-x 2 root root 607744 Sep 14  2010 /usr/bin/boinc

18:54 <whynot> it does

18:55 <SgrA> oh

18:55 <whynot> check 'rws' instead of 'rwx' of mostly any other executable

18:55 <whynot> now, we hope boinc_client doesn't drop just granted privileges

18:55 <SgrA> hm, restarted boinc.

18:55 <SgrA> (the service)

18:55 <SgrA> == boinc_client

18:56 <SgrA> but boincmgr still shows the same no usable gpus found thing

18:56 <whynot> what's in logs?

18:57 <SgrA> erm, forgot their path :<

18:58 <whynot> /path/to/boinchome/stdoutdae.txt

19:06 <SgrA> took a while, sorry.

19:06 <SgrA> http://pastie.org/2352825

19:06 <Romulus> Title: #2352825 - Pastie (at pastie.org)

19:07 <whynot> but wait, you've setuided boinc you should have to setuid boinc_client instead

19:07 <SgrA> D:

19:08 <SgrA> -rwsr-xr-x 2 root root 607744 Sep 14  2010 /usr/bin/boinc_client

19:08 <SgrA> both

19:13 <whynot> and?

19:13 <Romulus> It has been said that and is boinc (the daemon one) running, whynot

19:13 <SgrA> is it a smart AI bot? O_o

19:14 <whynot> but that doesn't answer my question

19:14 *** mynis has quit IRC

19:14 <SgrA> well boinc client is wsr

19:14 <SgrA> so, something is wrong

19:15 <whynot> I've meant, it still doesn't see GPU?

19:15 <SgrA> nope

19:16 <whynot> ok, can you pastebin this: cat /proc/`pgrep boinc`/status

19:17 <SgrA> http://paste.pocoo.org/show/456278/

19:17 <Romulus> Title: Paste #456278 | LodgeIt! (at paste.pocoo.org)

19:20 <whynot> goddamit, it still drops privileges

19:20 <SgrA> :(

19:21 <whynot> I've found this: http://projects.archlinux.org/svntogit/community.git/tree/boinc/repos/community-x86_64/boinc.rc so,

19:21 <Romulus> <http://tinyurl.com/3orre68> (at projects.archlinux.org)

19:22 <whynot> find that boinc.rc (I don't know where Arch puts them)

19:22 <SgrA> /etc/rc.d/boinc

19:22 <whynot> edit it,

19:22 <SgrA> mine is the same

19:23 <whynot> change BOINCUSER="boinc" to BOINCUSER="root"

19:23 <SgrA> done :s

19:24 *** zombie67 has joined #boinc

19:24 <whynot> and restart it, again (that becomes boring)

19:24 <SgrA> :P

19:24 <whynot> and?

19:24 <Romulus> Somebody said and is boinc (the daemon one) running, whynot

19:24 <SgrA> lol

19:24 <whynot> can I go to sleep now?

19:25 <SgrA> lol night :)

19:25 <whynot> I fail to see what you are loling at, I have to work tomorrow X(

19:26 <SgrA> :)

19:27 <whynot> then, can I go now?

19:27 <SgrA> night :)

19:27 <whynot> bye X(
