| |
| 08:59 | what 'kernel dir' are they talking about?

| 09:28 | <ltsppbot> "Gadi" pasted "This one should do the trick" (39 lines) at http://pastebot.ltsp.org/10
| |
| 09:29 | <Blinny> Gadi: pong!
| |
| 09:30 | Subhodip has joined #ltsp | |
| 09:30 | Pascal_1 has quit IRC | |
| 09:30 | <Gadi> Blinny: so, while I was in the car picking up the kids yesterday, I had a thought
| |
| 09:30 | we dont need LDM_USERNAME at all
| |
| 09:31 | <Blinny> Kids are good for that sort of thing.
| |
| 09:31 | Why not?
| |
| 09:31 | <Gadi> just use the $USER from the server's ssh connection
| |
| 09:31 | so, see the above paste
| |
| 09:32 | <Blinny> And $USER is equivalent to LDM_USERNAME post-login?
| |
| 09:32 | <Gadi> yup
| |
| 09:32 | bec it is the $USER of the ssh connection
| |
| 09:32 | and you connect as the user you log in as
| |
| 09:32 | QED
| |
| 09:32 | and such
| |
| 09:32 | :)
| |
| 09:32 | <ogra> you wont need the first command
| |
| 09:33 | <Gadi> just need to use single quotes instead of doubles
| |
| 09:33 | :)
| |
| 09:33 | mikkel has joined #ltsp | |
| 09:33 | <ogra> $USER will come from the servers env anyway, no need to explicitly pull it
| |
| 09:33 | <Gadi> ogra: ?
| |
| 09:33 | <ogra> userProcs isnt needed
| |
| 09:33 | <Gadi> sure it is
| |
| 09:34 | <ogra> oh, sorry
| |
| 09:34 | indeed it is
| |
| 09:34 | <Gadi> this scriptie should work - i think
| |
| 09:34 | * ogra is to distracted by work stuff, sorry | |
| 09:34 | <Blinny> This doesn't necessarily need to be chmod +x does it?
| |
| 09:34 | <Gadi> yeah, that was me yesterday :)
| |
| 09:34 | Blinny: shouldnt - it gets sourced
| |
| 09:34 | <Blinny> Right-O.
| |
| 09:35 | And where use singles? ~line15?
| |
| 09:35 | the sshdChildren line
| |
| 09:35 | <ogra> that walks the processtree, right ?
| |
| 09:35 | <Gadi> copy what I pasted exactly
| |
| 09:35 | <Blinny> Ah. Ok.
| |
| 09:36 | <Gadi> ogra: yeah - it will kill all procs except for those related to the newest sshd connection (which is our socket)
| |
| 09:36 | <ogra> sshdChildren=$(ssh -X -S ${LDM_SOCKET} ${LDM_SERVER} "/usr/bin/pgrep -P ${PPID}")
| |
| 09:36 | elisboa is now known as elisboa-off | |
| 09:36 | <Gadi> ?
| |
| 09:36 | that doesnt pake sense
| |
| 09:36 | * vagrantc wonders if it could use pattern negation instead of an ugly for loop | |
| 09:36 | <Gadi> *make
| |
| 09:37 | vagrantc: lets get it working first
| |
| 09:37 | :)
| |
| 09:37 | <vagrantc> heh :)
| |
| 09:37 | <ogra> Gadi, you want all processes that are childern of the currently running sshd
| |
| 09:37 | /usr/bin/pgrep -P ${PPID} in teh server will get you that
| |
| 09:38 | <Gadi> ah
| |
| 09:38 | well, same thing
| |
| 09:38 | still would need to grab the value of $PPID
| |
| 09:38 | <ogra> i'm pretty sure you can merge sshdChildren and sshdProc
| |
| 09:38 | <Gadi> as well as the value of the kids
| |
| 09:38 | <ogra> with some thinking
| |
| 09:38 | to save one tunneled request
| |
| 09:39 | <Blinny> Hrm. Clicking 'Cancel' doesn't return to LDM. Just stays on black screen w/ cursor.
| |
| 09:39 | <Gadi> yeah - im not prone to thinking
| |
| 09:39 | :)
| |
| 09:39 | yeah, ogra - that I need more help with
| |
| 09:39 | gracefully killing ldm
| |
| 09:39 | we dont store the pid, do we?
| |
| 09:40 | <ogra> nope, not atm
| |
| 09:40 | <Gadi> Blinny: does "OK" work?
| |
| 09:40 | <Blinny> Gadi: It did yesterday.
| |
| 09:40 | Gadi: I'll reboot & test.
| |
| 09:40 | <Gadi> cool
| |
| 09:41 | (yeah - but yesterday, we were hardcoding LDM_USERNAME for testing - today we use $USER)
| |
| 09:41 | <Blinny> Right
| |
| 09:42 | *poof* hopefully
| |
| 09:42 | Blinny has quit IRC | |
| 09:42 | <Gadi> yeah!
| |
| 09:42 | he died!
| |
| 09:42 | :)
| |
| 09:42 | how morbid
| |
| 09:42 | Blinny has joined #ltsp | |
| 09:43 | <Blinny> Ok works. (;
| |
| 09:43 | <Gadi> welcome back!
| |
| 09:43 | cool
| |
| 09:43 | so, now we just need to kill ldm well
| |
| 09:43 | on cancel
| |
| 09:44 | but, at least "OK" works
| |
| 09:44 | :)
| |
| 09:44 | <Blinny> You should still add the -center to your copy before -buttons :P
| |
| 09:45 | <Gadi> I wonder what a: pkill -P ${PPID} would get us
| |
| 09:45 | <Blinny> This isn't NeXTStEP ya know (;
| |
| 09:45 | <Gadi> heh
| |
| 09:45 | adding now...
| |
| 09:46 | hmm...
| |
| 09:46 | <Blinny> I thought we tried the pkill PPID yesterday.
| |
| 09:46 | <Gadi> did we?
| |
| 09:46 | damn
| |
| 09:46 | <Blinny> I can't say for certain.
| |
| 09:46 | <ogra> with proper brackets ?
| |
| 09:46 | <Blinny> I'm sure you're using subversion for this behemoth.. can you look back? (;
| |
| 09:47 | <ogra> it will only work as ${PPID}
| |
| 09:47 | <Blinny> May as well try it again
| |
| 09:47 | <Gadi> can you login to the thin client console and do: ps -ale >/tmp/junk
| |
| 09:47 | and paste /tmp/junk
| |
| 09:47 | (Im not on a client atm - and then I can see the process tree)
| |
| 09:48 | <Blinny> Any ideas how to accomplish such a feat? (pasting from the thin client's terminal)
| |
| 09:49 | <Gadi> scp the file to the server
| |
| 09:49 | so:
| |
| 09:49 | <Blinny> Oh. Heh
| |
| 09:49 | <Gadi> well, u get it
| |
| 09:49 | <ltsppbot> "Blinny" pasted "beer" (42 lines) at http://pastebot.ltsp.org/11
| |
| 09:50 | <epoxy|w3rk> if i add usplash, would i need to throw 'splash' in /whatever/tftpboot/boot/pxelinux.cfg or /usr/opt/i386/boot ?
| |
| 09:50 | gah.. ruined the path names.. but you get what i mean :)
| |
| 09:51 | <ogra> epoxy|w3rk, it should be in there by default (and be set up by default)
| |
| 09:51 | oh, wait, you were the etch user ...
| |
| 09:51 | * ogra remembers | |
| 09:51 | <epoxy|w3rk> haha
| |
| 09:51 | * epoxy|w3rk sighs | |
| 09:51 | <ogra> well, yeah, that *might* work
| |
| 09:51 | i never tried usplash in debian
| |
| 09:51 | Subhodip has quit IRC | |
| 09:51 | <epoxy|w3rk> well it sucks :)
| |
| 09:52 | i threw it in both.. to no avail. i can just stick with quite... my boss just doesnt want users seeing init scroll by
| |
| 09:52 | <ogra> or use ubuntu :)
| |
| 09:52 | <epoxy|w3rk> true..true :)
| |
| 09:53 | F-GT has quit IRC | |
| 09:54 | Subhodip has joined #ltsp | |
| 09:54 | <Blinny> Gadi: pkill'ing the PPID provides different result - back to blinkenkursor
| |
| 09:54 | I lost the mouse & x resolution
| |
| 09:55 | Can't we just throw a -HUP to one of these?
| |
| 09:55 | <Gadi> blinny did you do: pkill -P ${PPID}
| |
| 09:55 | ?
| |
| 09:55 | <Blinny> Yes.
| |
| 09:56 | <Gadi> try this:
| |
| 09:56 | <Blinny> pkill -P ${PPID}
| |
| 09:57 | <Gadi> hmmm...
| |
| 09:57 | we need to kill ldm, too
| |
| 09:57 | so: pkill -P ${PPID}
| |
| 09:57 | pkill ${PPID}
| |
| 09:57 | <rjune> !g
| |
| 09:57 | <ltspbot> rjune: "g" is Gadi!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 09:57 | <Gadi> rjune!
| |
| 09:58 | <Blinny> updating now
| |
| 09:59 | <Gadi> hopefully we dont kill ourselves before we can kill daddy
| |
| 09:59 | if we are, we may need to pgrep everything and then go about killing them all
| |
| 09:59 | :)
| |
| 10:00 | or maybe there's a better way...
| |
| 10:00 | rjune: you're an assassin by trade - how do you make it look so easy?
| |
| 10:01 | oh, wait
| |
| 10:01 | ogra, vagrantc: is ldm called in a loop from the screen script?
| |
| 10:01 | or is the loop maintained from within ldm?
| |
| 10:01 | <rjune> Gadi: you know I can't talk about that.
| |
| 10:02 | * Gadi seems to think that we did it right by killing PPID | |
| 10:02 | <Gadi> but, that killed ldm
| |
| 10:02 | and the screen script doesnt respawn it
| |
| 10:02 | <rjune> killall -9 1
| |
| 10:02 | * Gadi checks code... | |
| 10:02 | <rjune> killall -9 init
| |
| 10:02 | <ogra> then you didnt use the server side PPID
| |
| 10:02 | <rjune> that'll fix all your problems
| |
| 10:03 | <Gadi> oh... the server side PPID
| |
| 10:03 | that's a good idea
| |
| 10:03 | <ogra> :)
| |
| 10:03 | <Gadi> :)
| |
| 10:03 | <Blinny> pkill ${PPID} didn't kill anything, just logged the user right in.
| |
| 10:03 | <Gadi> yeah, here
| |
| 10:03 | Ill paste a better one
| |
| 10:03 | <Blinny> Does it have the -center? (;
| |
| 10:04 | <ltsppbot> "Gadi" pasted "This one should do the trick - really!" (39 lines) at http://pastebot.ltsp.org/12
| |
| 10:05 | <Gadi> or alternatively...
| |
| 10:05 | <ltsppbot> "Gadi" pasted "This one should do the trick - really!" (39 lines) at http://pastebot.ltsp.org/13
| |
| 10:05 | twinprism has quit IRC | |
| 10:05 | <Gadi> something along either of those lines
| |
| 10:06 | one kills the socket's parents (i think)
| |
| 10:06 | <Blinny> Is it just that one line that changed?
| |
| 10:06 | <Gadi> the other should kill the socket's parents' kids
| |
| 10:06 | yeah
| |
| 10:06 | note the single quotes
| |
| 10:06 | that's important
| |
| 10:07 | <Blinny> Which to try first?
| |
| 10:07 | Ronin1234 has joined #ltsp | |
| 10:07 | <Gadi> hmmm
| |
| 10:07 | RoninBaka has quit IRC | |
| 10:07 | <Gadi> try the first one first
| |
| 10:07 | and the second one second
| |
| 10:08 | its only fair
| |
| 10:08 | the first one *did* come first
| |
| 10:08 | <Blinny> We wouldn't want to make it feel slighted.
| |
| 10:10 | OK. First one no worky. Back to mouse & blackscreen.
| |
| 10:10 | F-GT has joined #ltsp | |
| 10:13 | <Blinny> OK. Second one no worky. Back to mouse & blackscreen.
| |
| 10:13 | <Gadi> hmm...
| |
| 10:14 | just make sure on the client that the file is changing
| |
| 10:14 | wouldnt want to chase a rabbit
| |
| 10:14 | or wild goose
| |
| 10:14 | <Blinny> It is.
| |
| 10:14 | <Gadi> or any kind of farm animal or undomesticated cousin
| |
| 10:14 | <Blinny> I had checked that - thinking the same thoughts.
| |
| 10:15 | <Gadi> are you still at the blackscreen?
| |
| 10:15 | stay there a sec
| |
| 10:15 | and do a ps -efw on the server and look to see how many sshd procs are running as you
| |
| 10:16 | oh, duh!
| |
| 10:16 | we can do better than PPID
| |
| 10:17 | <ltsppbot> "Gadi" pasted "This one should do the trick - really!" (39 lines) at http://pastebot.ltsp.org/14
| |
| 10:17 | <Gadi> we have sshdProc!
| |
| 10:17 | <Blinny> Two ssh processes, no sshd
| |
| 10:17 | <Gadi> thats the one we need to kill
| |
| 10:17 | on the server?
| |
| 10:18 | you should have sshd procs
| |
| 10:18 | <Blinny> Sorry. Was on the client.
| |
| 10:18 | For this user, I have 6.
| |
| 10:18 | 3 groups of 2
| |
| 10:18 | (rebooting client now w/ sshdProc)
| |
| 10:24 | I'm sorry to say, black screen & cursor again.
| |
| 10:25 | <Gadi> damn
| |
| 10:27 | * Blinny nods. | |
| 10:28 | * Gadi thinking... | |
| 10:28 | <ogra> do you kill ldm or also X ?
| |
| 10:28 | * ogra would only kill X | |
| 10:28 | <Gadi> no, now we are killing the server-side sshd
| |
| 10:28 | as you suggested
| |
| 10:28 | the server side of the socket
| |
| 10:28 | <ogra> hmm, the right one ?
| |
| 10:28 | here are two
| |
| 10:29 | the first only gets the tunnel up ... the second starts the session
| |
| 10:29 | <Gadi> right
| |
| 10:29 | <ogra> the rc scripts sit between the two calls iirc
| |
| 10:29 | <Gadi> well, there is one sshd, no?
| |
| 10:29 | doesnt the same one control all
| |
| 10:29 | <ogra> i'm not sure it doesnt spawn a second one
| |
| 10:30 | <Gadi> because the second ssh call uses the same socket
| |
| 10:30 | <ogra> right but if you catch the second instead of the first it wont kill ldm
| |
| 10:30 | check that
| |
| 10:30 | <Gadi> will do
| |
| 10:30 | <ogra> i'm not sure if there is one or two sshds
| |
| 10:31 | <Blinny> I see one as root, one as the user.
| |
| 10:31 | In each instance, 2 PIDs separate the two
| |
| 10:32 | sshd: myUser [priv] and sshd: myUser@pts/9
| |
| 10:33 | staffencasa has joined #ltsp | |
| 10:33 | <Gadi> ogra: it doesnt spawn another sshd
| |
| 10:34 | I did a quick test just ssh'ing into a machine - once with a master socket and the second using that socket
| |
| 10:34 | with both connected, only one sshd
| |
| 10:39 | <ogra> oki

| 11:33 | <mighty-d> Gadi: ok thanks, any hint on what could be causing the slow behaviour?
| |
| 11:34 | <Blinny> LDM_DIRECTX ?
| |
| 11:34 | <Gadi> is it slow to boot or slow once you are logged in?
| |
| 11:34 | <mighty-d> gadi, slow once im logged inç
| |
| 11:34 | <Blinny> mighty-d: though I've noticed that hardy is much more sluggish than my FC6+LTSP4.2 box was
| |
| 11:34 | <Gadi> then, try setting LDM_DIRECTX=True
| |
| 11:34 | as blinny says
| |
| 11:35 | <mighty-d> Blinny: this clients where running on a slackware 11 + ltsp 4.2 and run ok
| |
| 11:35 | <Gadi> by default, all video is securely tunneled thru ssh
| |
| 11:35 | which tends to be slow on older clients especially
| |
| 11:35 | LDM_DIRECTX turns that off
| |
| 11:35 | <Blinny> I blame gnome eycandy.
| |
| 11:36 | <mighty-d> Ok, lets see
| |
| 11:38 | <Blinny> mighty-d: Don't forget to create the [default] section header in lts.conf.
| |
| 11:39 | <mighty-d> Blinny: yeah, thanks, it seems to work
| |
| 11:40 | F-GT has joined #ltsp | |
| 11:40 | <Blinny> mighty-d: Weeha!
| |
| 11:40 | <mighty-d> Gadi: thanks, Blinny, thanks, ssh its taking too much time to log in, is there a way to tune it up
| |
| 11:40 | ?
| |
| 11:40 | Blinny: yeah, i was breaking my head with that one
| |
| 11:41 | <Blinny> mighty-d: Sounds like name resolution issues.
| |
| 11:41 | mighty-d: You can either add all your hosts to /etc/hosts, or set them up so they resolve correctly (192.168.0.1->ws001 and ws001->192.168.0.1)
| |
| 11:41 | mighty-d: Dig?
| |
| 11:42 | <mighty-d> Blinny: thanks, i gotta change my chroot password... i dont remember how to build the squashfs on ubuntu, would you give me that last clue?
| |
| 11:42 | <Blinny> mighty-d: ltsp-update-image --arch i386
| |
| 11:42 | mighty-d: You can leave the --arch i386 if your server is not x86_64 though

| |
| 11:43 | mighty-d: http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/ ain't a bad handbook, even if you're not using the Edubuntu flavor.
| |
| 11:44 | <mighty-d> ok, gotta read it, thanks Blinny

| 12:20 | <LTSP> Hi! A question I had recently, and knew the team here would know the answer... I'm looking for a faster graphical remote access than VNC (road warrior getting into office server scenario). LTSP has much greater speed than any VNC I've tried on the same LAN with the same equipment. Any suggestions where I should look? Is anyone working on something like this?

| 12:52 | <cliebow> LTSP:you looked at nx?
| |
| 13:00 | F-GT has joined #ltsp | |
| 13:01 | <irule> LTSP you may also vpn and "X -query server:port"
| |
| 13:03 | <LTSP> I haven't looked at NX (other than just googling and taking a peek) - is it fast?
| |
| 13:04 | I didn't know LTSP could work across WAN.... how to try out the "X -query server port" (or is that all I'll need to experiment?).
| |
| 13:05 | <fie_wr0k> I was wondering if LTSP supports sessions like terminal services? Where you can close the RDP window and then re-open it from another computer?
| |
| 13:05 | And your xsession/apps are stored in ram or whatever.
| |
| 13:06 | <rjune> irule: X -query isn't so great over a wan
| |
| 13:06 | fie_wr0k: LTSP does not as far as I know. You can however do it with VNC and/or NX
| |
| 13:08 | <ogra> there are some solutions, no sane one though ...
| |
| 13:08 | xmove would be one
| |
| 13:09 | xvfb in combination with vnc would be another (you can "park" you vnc connection in the virtual framebuffer provided by xvfb)
| |
| 13:10 | <fie_wr0k> hmmm
| |
| 13:10 | <ogra> the proper solution would be to add such functionallity to Xorg though
| |
| 13:12 | <irule> LTSP how avout using the TIGHT compression within vnc, 64 colors and a few tweaks? that is what I use with vnc, it works like a charm
| |
| 13:13 | <fie_wr0k> ogra, so ltsp aims to be an open solution compared to vnc/nx?
| |
| 13:13 | <irule> LTSP I use vnc within a vpn wan, I have basic adsl service on all sites
| |
| 13:14 | fie_wr0k no
| |
| 13:14 | <ogra> fie_wr0k, yes
| |
| 13:14 | <fie_wr0k> :)
| |
| 13:14 | <irule> fie_wr0k there is no fttp nfs etc in vnc/nx
| |
| 13:15 | fie_wr0k plus, vnc is open as well, as well as the nx client
| |
| 13:15 | <ogra> right, vnc is free, nx isnt (apart from the client to whetten your taste for the commercial version)
| |
| 13:16 | Ryan52 has joined #ltsp | |
| 13:17 | <ogra> and sadly the way nx is implemented will never even allow the free client in any distros (it ships its own hacked up copy of xlibs which is a nono in most distros)
| |
| 13:18 | <dberkholz> we have a nxserver-freenx package...
| |
| 13:18 | <ogra> dberkholz, youre not shipping binaries on CDs :)
| |
| 13:19 | spectra has joined #ltsp | |
| 13:19 | <dberkholz> oh btw, you might be interested in Xpra
| |
| 13:19 | <ogra> there are ubuntu and debin packages and for sure there are rpms for varuious rpm based distros ... but none of these are included
| |
| 13:19 | <dberkholz> it's an X server that supports disconnects & reconnects
| |
| 13:19 | <ogra> yay
| |
| 13:19 | <dberkholz> http://partiwm.org/wiki/xpra
| |
| 13:19 | <ogra> a properly developed xmove ?
| |
| 13:19 | |Ryan52 has quit IRC | |
| 13:19 | <ogra> xmove already does the right thing its just a horrible implementation
| |
| 13:20 | <dberkholz> i haven't actually looked at it yet, just noticed it and bookmarked for later investigation
| |
| 13:20 | <ogra> (which i wouldnt expect different from a proof of concept implementation for a thesis though)
| |
| 13:20 | Ryan52 is now known as |Ryan52 | |
| 13:26 | <LTSP> Xpra looks interesting
| |
| 13:27 | ogra, is xmove or xpra the one on a thesis project
| |
| 13:30 | <ogra> xmove was
| |
| 13:34 | <warren> xmove stopped in 1997
| |
| 13:34 | <LTSP> Are xpra and/or xmove setup (or other similar projects) so the client locally runs the GUI and only minimal text/data is sent back and forth (I'm thinking how the MMORPGs seem to be executed) vs VNC that is trying to send graphic data back and forth and hence its slowness.
| |
| 13:34 | Nubae has quit IRC | |
| 13:35 | <warren> reading about how it works
| |
| 13:36 | it sounds like VNC is the most bandwidth efficient
| |
| 13:36 | Nubae has joined #ltsp | |
| 13:36 | <warren> keep in mind that you have bandwidth usage and latency
| |
| 13:36 | VNC uses far less bandwidth at the expense of higher latency
| |
| 13:40 | plamengr has joined #ltsp | |
| 13:43 | <LTSP> So how is LTSP so much faster than VNC, across the LAN? LTSP trades bandwidth for latency then?
| |
| 13:46 | <rjune> LTSP uses X
| |
| 13:46 | which works very well over a low latency, high bandwidth link
| |
| 13:46 | <warren> VNC has nothing to do with LTSP
| |
| 13:46 | <rjune> warren: there is some historical context there.
| |
| 13:46 | <warren> well sure
| |
| 13:47 | <rjune> anyway, VNC compresses it and works better for low bandwidth high latency link
| |
| 13:47 | <warren> internet is generally too slow to do X
| |
| 13:50 | <LTSP> Xpra/others will then be slow from the start (since they use X)?
| |
| 13:51 | <warren> I've never used xpra
| |
| 13:51 | LTSP: this is generally not a solved problem
| |
| 13:51 | LTSP: if there were a better solution then everyone would be using it
| |
| 13:55 | <LTSP> Thanks guys, I have to head to an offsite... you gave me some things to think about, some research to do, and maybe improved questions to follow up with. J

| |
| 15:28 | I have an ugly version of ldm gtkgreet embedded X keyboard layout setting
| |
| 15:30 | <vagrantc> wacky.
| |
| 15:30 | you LTSP devs all turn to embedded devs eventually.

| |
| 15:33 | <vagrantc> ah, yes. always forgetting my goals in the end.
| |
| 15:33 | good that i have rjune to turn to to keep faith.
| |
| 15:35 | <rjune> lol
| |
| 15:41 | <warren> sourceforge's list server is slow....
| |
| 15:42 | Attached is a preliminary implementation of X keyboard layout setting within ldm gtkgreet. The XKB* environment variables are already present in the greeter process, and it must be done here synchronously in order to guarantee that the keyboard layout is properly set before the user can type anything.
| |
| 15:42 | Any comments on this patch or suggestions of how it can be improved? Otherwise I would like to commit this in ldm-trunk soon.

| 16:45 | <Gadi> well, now I know why ldm doesnt die...
| |
| 16:45 | *sigh*
| |
| 16:47 | <ogra> take a gun
| |
| 16:47 | yore ameican you got the right to :P
| |
| 16:48 | <Gadi> well, if an rc.d script kills the control socket, the x_session ssh call that ldm makes will hang waiting for a password
| |
| 16:48 | thats why he gets stuck at black screen + mouse
| |
| 16:49 | a simple check for the existence of the socket before running x_session would fix it
| |
| 16:49 | <ogra> kill the local X
| |
| 16:49 | that should clean up everything and properly respawn ldm
| |
| 16:49 | <Gadi> hmm...
| |
| 16:50 | I think that ssh call would still be executed, no?
| |
| 16:50 | <ogra> if the parten goes away ?
| |
| 16:50 | *parent
| |
| 16:50 | that would be a bug imho
| |
| 16:50 | <Gadi> well, its parent is ldm
| |
| 16:50 | not X
| |
| 16:50 | <ogra> (not sure it does though)
| |
| 16:50 | well, X will tear down ldm
| |
| 16:50 | <Gadi> X ans ssh are both children of ldm
| |
| 16:50 | <warren> ogra: I rewrote the scopy parts to standard string.h functions but it became less simple looking, so reverted.
| |
| 16:50 | <Gadi> I dont think so
| |
| 16:50 | not how it is written
| |
| 16:51 | <ogra> warren, i'm not saying its wrong, imho just commit it ... i was just wondering if glib doesnt have any code you could just use directly like scopy
| |
| 16:52 | so the function wouldnt be needed and the rest of the code would stay the same
| |
| 16:52 | seems like a common task to make sure to have the string zeroed if there is nothing in the coyp surce
| |
| 16:52 | *copy
| |
| 16:53 | <warren> I'm tagging this as ldm-2.0.7
| |
| 16:54 | <Gadi> ogra: ldm is not wrapped in a loop, right?
| |
| 16:54 | <warren> Gadi: from screen.d it is
| |
| 16:54 | <ogra> not anymore
| |
| 16:54 | <Gadi> neither it nor the screen script that calls it
| |
| 16:54 | <warren> oh wait
| |
| 16:54 | <Gadi> yeah
| |
| 16:54 | <warren> I loop it, but maybe you don't.
| |
| 16:54 | <Gadi> thats why we have no luck killing ldm
| |
| 16:54 | |Ryan52 is now known as Ryan52 | |
| 16:55 | <Gadi> so, I guess the upshot is - something needs to be patched
| |
| 16:55 | :)
| |
| 16:55 | which do you guys think is better - to kill the socket or to kill ldm?
| |
| 16:55 | <ogra> Gadi, it is in a loop
| |
| 16:55 | while :; do
| |
| 16:55 | ...
| |
| 16:56 | <Gadi> ah - in hardy as well?
| |
| 16:56 | <ogra> thats from a fresh hardy chroot
| |
| 16:56 | * ogra just tested a lot of geode stuff for the 8.04.1 CD | |
| 16:58 | <Gadi> hmm.. so killing daddy and not grandpa should work
| |
| 16:58 | daddy should be ldm and grandpa should be the screen script
| |
| 16:58 | <ogra> yeah
| |
| 16:59 | <Gadi> kill -9 ${PPID}
| |
| 16:59 | easy enuff
| |
| 16:59 | I wonder if we ever tried that one
| |
| 16:59 | <ogra> if that doesnt work, worst case lsof | grep $LDM_SOCKET and pull the pid out there to slay the ssh client
| |
| 17:00 | <Gadi> killing ssh client wont help
| |
| 17:00 | we need to bring down ldm
| |
| 17:00 | so it doesnt proceed to spawn the next ssh client
| |
| 17:00 | <ogra> i thought thats what ldm was waiting for in your scenario
| |
| 17:00 | <Gadi> only after rc.d scripts finish
| |
| 17:00 | then it tries to do the x_session ssh
| |
| 17:01 | but without a control socket, it falls back on password

| 17:22 | <vagrantc> warren: look forward to tryinng ldm 2.0.7 on debian :)
| |
| 17:22 | although, i don't really have any way to verify it ...
| |
| 17:22 | * ogra looks forward to CONFIGURE_X=False by default :) | |
| 17:23 | <vagrantc> indeed.
| |
| 17:23 | <ogra> its one major step
| |
| 17:23 | <vagrantc> looks like debian unstable(maybe testing) uses a very skeletal xorg.conf
| |
| 17:23 | <ogra> we do so since gutsy
| |
| 17:23 | keyboard and mouse sections only
| |
| 17:24 | and its planned that these go away in intrepid
| |
| 17:24 | in favour of hal input
| |
| 17:24 | <vagrantc> i'm hoping to sit down and get a reasonable Xsession handling one of these days.
| |
| 17:24 | <ogra> oh, well, then go ahaed :)
| |
| 17:25 | * ogra was actually planning to do that on his way to boston ... | |
| 17:25 | <ogra> but if you go for it i wont stop you :)
| |
| 17:25 | <vagrantc> heh.
| |
| 17:25 | i hope someone remembers what we had agreed to implement :)
| |
| 17:26 | <ogra> roughly, yes
| |
| 17:26 | <vagrantc> this is where mailing lists beat out irc conversations.
| |
| 17:26 | <ogra> well, only in channels without logs :)
| |
| 17:26 | i have logging on in xchat
| |
| 17:26 | (i think)
| |
| 17:26 | * ogra checks | |

| |
| 17:28 | i dont
| |
| 17:28 | damned fresh HW with new installs ...
| |
| 17:28 | * ogra fixes | |
| 17:29 | <ogra> one of these days i'll find the time ad set up a proper logbot for #ltsp, its annoying to not have searcheable logs like i do in all other channels i'm in

| 17:51 | <ogra> vagrantc, ldminfo provides the location of Xsession, we have an rc.d script that kicks in and walks the different paths if we dont have the information from ldminfo ... tha actual session manager always gets attached to Xsession and by default we call the "default" session in all cases LDM_SESSION will only override the session manager call
| |
| 17:52 | and distro packagers should reorder the rc.d script to have their default path first so we limit the slowdown to connections to foreign distros
| |
| 17:53 | i think that was merely what we agreed on
