hi
06:40
could so help me booting my thin client?
06:41
<daduke>
Big-K: don't know yet, let's see. What's your problem?

ending up in ash
06:42
seems like nbd cannot mount the chroot
06:43
os is debian testing
06:43
do i have to configure nbd?
06:44Munkie has quit IRC
06:44
<daduke>
Big-K: haven't used nbd yet, I'm on etch+tftp+nfs
06:45
<Big-K>
what version are u running?
06:45
aahh that 4.2 ifaik
06:45
<daduke>
Big-K: version of ....?
06:45
<Big-K>
ltsp
06:47
<daduke>
Big-K: vanilla etch, 5.0.39
06:48
<Big-K>
hmmm
06:48
maybe I should try etch too
06:48
ltsp version is the same
06:49daya has joined #ltsp
06:49
<Big-K>
daduke did u configure ltsp to use nfs?
06:49
or is it standard?
06:57
<daduke>
Big-K: it's standard. Can you access https://nic.phys.ethz.ch/readme/233 ? These are my install notes
07:03
<Big-K>
thx
07:09
hmmm I thought nbd would be standard since ltsp v5

<tuff>
hello. can someone tell me why is this line "env['DISPLAY'] = 'localhost:10.0'" in /usr/sbin/ltspfsmounter ?
08:30
<daduke>
tuff: afaik, nobody really knows. But it's accepted that it prevents localdevices from being mounted.
08:32
<tuff>
I just came to the same conclusion
08:35Gadi has joined #ltsp
08:36
<daduke>
tuff: thing is, everybody recommends to kick it out, et voila, mounting works, but only for the first user (for me and many others). Do you also see this?
08:38val_ has joined #ltsp
08:38
<val_>
hello
08:39
<daduke>
val_: hi val_.
08:39
<val_>
how i can start nfs fo ltsp?
08:39putty has quit IRC
08:39
<val_>
my log is "rpc unable to receive...."
08:39
<tuff>
daduke: you mean after the line is out mounting works just for first user?
08:40
<val_>
but portmap is availible
08:40
<daduke>
tuff: for my LTSP 5 on Debian etch, yes. I've seen many similar reports.
08:40putty has joined #ltsp
08:41
<daduke>
val_: how about trying to mount NFS from another machine first? Easier to debug than the whole LTSP setup.
08:42
<tuff>
daduke: I am not any more near that server at the moment but I will test it.
08:43
<daduke>
tuff: ok.
08:43
<Munkie>
Is it "Dangerous!" to mount the filesystem rw? I want to compile the nvidia kernel module but as kernel is a different arch and I don't know about cross-compiling, I thought using modules-assistant from a running client might be the answer.
08:45
<daduke>
Munkie: if you just do it once from one connected client, you should be safe. Just make sure only one client mounts the fs. You also might have to circumvent the tmpfs overlay.
08:45
<val_>
daduke which pack i need install "unfs3 nfs-user-server nfs-kernel-server"?
08:46
<Munkie>
daduke: ok, thanks
08:46
<tuff>
daduke: we did a migration to ubuntu/ltsp-5 and local devices worked. Today I went to the client and noticed that local devices do not work. started to debug and arrived at that particular line. when I commented it out, mounting started to work on that terminal.
08:46
<daduke>
val_: which distro? nfs-kernel-server should be fine
08:47
<val_>
etch
08:47
debian
08:48
<daduke>
tuff: ubuntu might be more up to date than etch. Maybe they fixed it already. But then, this line was still there...
08:48
val_: nfs-kernel-server
08:49
<val_>
ok ltsp admin tell me: " nfs Yes Yes no"
08:49
<tuff>
daduke: I just remembered, just before leaving I popped the usb drive to another terminal and it also worked. This should count as second user, although I logged out from first terminal.
08:49
<daduke>
val_: iirc ltsp_admin is from an older ltsp version.
08:50
<val_>
<daduke> all greate
08:50
but it s jumping so crazly
08:50
<tuff>
the first user thing should come from that when ssh does X forwarding it sets the display to localhost:10.0 for first user on that machine
08:50
<daduke>
tuff: not sure about that, I think it's 'first of the logged-in users'
08:51
<tuff>
second user gets 11.0 and so on. So removing the line should actually make it work for all.
08:51
<daduke>
tuff: yeah sure, but even with this line gone it doesn't work for serveral users on several machines
08:53
<val_>
daduke modprobe: Fatal. Faild to open config file /etc/modprobe.devfs
08:53
may be some wrong in configs
08:56
<Gadi>
morning, guys. There is definitely that multi-user bug in the latest localdev stuff: You need to edit /usr/sbin/ltspfsmounter and comment out the line: that sets the DISPLAY env var to localhost:10
09:04
<tuff>
thanks for confirming that the line is the problem
09:04
gotta go now
09:05tuff has quit IRC
09:06
<daduke>
Gadi: we've been talking about this.. problem is, in my setup removing this line allows mounting per se, but multi-user mounting still doesn't work
09:08
<Gadi>
daduke: do you insert the USB stick *beore* logging in thru ldm?
09:08
when you test?
09:08
because I believe there is another line in: /opt/ltsp/i386/usr/share/ldm/rc.d/S10-delayed-mounter that needs changing
09:08
(add a "-X" to the ssh line there)
09:09
and, if you are on ubuntu, reroll the image
09:09
(ltsp-update-image)
09:09
<daduke>
Gadi: no, after logging in. I added the -X (it's necessary to correct for an ssh token that's gone). I'm on etch -> direct nfs.
09:11
<Gadi>
daduke: can you switch to a shell on the thin client and list the processes
09:11
see if there is an ssh process hanging after the big one
09:12
<daduke>
Gadi: sure, hold on a sec
09:14
Gadi: with or w/o USB stick plugged in? 'the big one' being what?
09:14
Gadi: w/o stick, there's no ssh process
09:14
<Gadi>
if you do: ps -ef|grep ssh
09:14
there should be 2 normally
09:15
then, when you plug in the USB
09:15
there should be a third for a few secs that goes away
09:15
unless it hangs
09:15
thats the one issuing the ltspfsmounter command
09:16
<daduke>
Gadi: ah wait, I disabled LDM_DIRECTX. I guess that why I don't have one.
09:16
<Gadi>
nah, you should still have
09:16
with or without LDM_DIRECTX
09:17
<daduke>
Gadi: ps -ef|grep ssh just shows me the grep line
09:17
<Gadi>
on the thin client?
09:18
<daduke>
Gadi: yup. I swear ;)
09:18
<Gadi>
do you use ldm?
09:18
<daduke>
Gadi: yup.
09:18
<Gadi>
and are you logged into a session?
09:20daya has quit IRC
09:22
<daduke>
Gadi: got me there. No, I wasn't.
09:22
Gadi: sorry
09:22
<Gadi>
my bad
09:22
:)
09:23
once you login, you should have 2 ssh procs running
09:23
when you insert a USB, you should see a third
09:23
that should go away quickly
09:23
so, if you see only 2 that may be ok
09:23
but, if you see the third and it just sits there, then thats not good
09:24
<daduke>
Gadi: yes, you're right. 2 and ... one with ltspfsmounter
09:24
<Gadi>
does ltspfsmounter go away?
09:26
<daduke>
Gadi: I have to reboot to get things straight...
09:26
<Gadi>
ok
09:26
side question: do you have any problems with not being able to logout fully?
09:26
and needing to reboot the terminal to get back a login screen?
09:27
<daduke>
Gadi: nope, that's fine. Is it related?
09:27* daduke just checks again to make sure...
09:28
<Gadi>
it could be - I have one deployment atm that has that problem, and I have been trying to figure out what's gumming up the works - its quite bizarre - but prolly unrelated to your issue atm
09:29
<daduke>
Gadi: logging out works fine.
09:31
Gadi: ok, no stick -> 2 sshs, but it says 'ltspfsmounter all cleanup' in the second one already.
09:31
<Gadi>
thats for after you logout
09:31
it cleans up ltspfs mounts
09:32
<daduke>
Gadi: with stick -> don't see a third, maybe I'm too slow.. try again..
09:33
Gadi: ah, got it. /usr/sbin/ltspfsmounter. Gone again after 0.5 s
09:33
<Gadi>
ok, thats good
09:34
<daduke>
Gadi: now let me try on a second client...
09:34
<Gadi>
ah, gotta run to a meeting

10:09
<daduke>
Gadi: I'm on my way home, back in this channel in 30 min. Mounting on a 2nd client/user doesn't work, I don't see the ltspfsmount ssh, but I do see the volume icon of the first user (no access tho).
10:10
<daniQ>
cliebow - much bigger...it's amazing how much weight you can put on in 6 months..but i haven't doubled it size or anything so i think i'm still good. i keep thinking of manatee's .
10:10
<cliebow>
hahahha
10:11
leigh keeps thinking of you..
10:11
<daniQ>
cliebow - i am having some computer issues on the microcr*p side..something about spyware on the registry keys and i have been trying to get rid of it but it keeps poping up. something happened during the last power outage that made that side weird.
10:12
i miss leigh...maybe i'll call her at work and pester her with baby questions....
10:12
<cliebow>
i see..you have adaware and spybotsd there??
10:12
she would love to hear from you
10:12
<daniQ>
yes...we have some sort of spywear program and i use it regularly...
10:13
i hate it when the internet seems scary
10:13
<cliebow>
you might have to start in safe mode with f8 at bootup and run adaware/spybot
10:14
<daniQ>
i didn't know of you could look at it maybe over your x-mas break...i would use the ubuntu side more if the sound would work
10:14
i'd buy you as many coke's as you would want : )
10:15
and trade some gardening next year

10:38

no...she needed so much time from me and i really didn't want to lift all the heavy packages anymore. i might re-apply in a few years but i'll do it as a clerk not a PMR
10:38
i wish i had worked for leigh
10:38
<cliebow>
so far away..
10:39

yes but a more understanding boss...not that i was in a bad situation but i felt like my main gardening job wasn't respected as a real thing

10:52
I got a weird problem
10:52
on the thin client, gnome runs, but the panel bar can not be accessed, the menus won't open etc
10:52
on the server, it works better, but several panel apps crash on startup
10:53
Probably somethign stupid on my side, but has anyone heard about this problem ?

11:32

Gadi: just virtualbox
11:32
Gadi: what sort of something?
11:32
<Gadi>
ah, well, that might help
11:32
I am still trying to route out a problem at a client's and have been running various tests
11:32
all of which come up fishy
11:33
I have set it up so I can ssh to the thin client
11:33
if I ssh into the thin client, with the user logged in, I am trying to just execute: ssh -X -S <socket> <server> echo hi
11:33
and that keeps hanging on me
11:33
when, of course itshould not
11:34
I am trying to find out what's guming up my ssh socket
11:34
<cyberorg>
Gadi, ssh -vvv -X -S <socket> <server> echo hi
11:35
<Gadi>
cyberorg: yeah, it hangs trying to read from the socket
11:35

12:18
now, maybe I had an older version or something
12:18

hrm
12:18

but, when I removed it - all is better
12:18
my users weren't able to logout
12:18
<lns>
veeeery interesting!
12:19
<Gadi>
it would stop at the gnome background wallpaper
12:19
and get stuck
12:19
finally realized it was due to xterminator in the Xsession.d
12:19
moved that out of the way and presto!
12:19
<lns>
maybe xterminator killed a process too soon? I thought it was supposed to wait a specified amount of time before starting to kill stuff

took FOREVER to find that one
12:20* Gadi thinks it may have killed the master socket connections
12:20
<Gadi>
er, connection
12:20
<lns>
aahh, for the thin client connection itself?
12:20
<Gadi>
that would explain why I couldn't attach future procs to the master socket
12:20
and why things would hang
12:20
yeah
12:21
<lns>
is the master socket supposed to be owned by a logged in user?
12:21
<Gadi>
I feel like I'm on "House"
12:21
that would explain all the symptoms
12:21
;)
12:21
<lns>
that's really weird to me..although i don't completely understand the scenario
12:22
you would think the ssh socket would be owned by someone other than a user that logs in after ldm is started.. ?
12:22
<Gadi>
well, in ldm Gutsy, we establish a master ssh socket first, before the session one
12:22
scotty calls it a "sentinel"
12:22
I believe
12:22
<lns>
ok
12:22
<Gadi>
that's the one with LTSP_ROCKS in it
12:22
if you've ever seen that
12:22
<lns>
nope =p
12:22
not yet anyway
12:23
<Gadi>
well, at a thin client shell, do: ps -ef|grep ssh
12:23
after you log into ldm
12:23
you'll see it
12:23
<lns>
k
12:23
<Gadi>
anyhow, I think xterminator was killing the socket on the server end
12:24
even tho it was still open on the client end
12:24
<lns>
aahh... therefore borking the session upon logout
12:24
<Gadi>
so, sshd on the server was having trouble closing the socket
12:24
<lns>
at that precise instant during logout and xterminator activates
12:25
<Gadi>
and, my removable media was broken bec udev on the client tried to send signals thru the broken socket
12:25
<lns>
ooo
12:25
<Gadi>
nah - it broke the session on login
12:25
but the second ssh session had already connected
12:25
and I waas using LDM_DIRECTX, so the session was fine
12:25
<lns>
xterminator activates on login too?
12:25
<Gadi>
(didnt rely on the ssh xproxy)
12:26otavio has joined #ltsp
12:26
<Gadi>
xterminator only runs on login
12:26
thru Xsession.d
12:26
<lns>
ooh
12:26
ok..confused with an earlier LP bug workaround
12:26* Gadi slaps head - it all makes so much sense now
12:26
<lns>
haha
12:26
good work!
12:26
<Gadi>
*sigh*
12:26
that one plagues me for weeks now
12:26
er, plagued
12:27
<lns>
wow, you had not-to-be-logged-out-users for weeks?
12:27
<Gadi>
yeah - they got used to cycling the power on the clients in themorning
12:27
er, morning
12:27
<lns>
oh man
12:27
hehe
12:27

not that they were happy

<Janet32766>
help!? all my thin clients stopped booting, console login works, any guidelines on how to diagnose?
12:31
<lns>
Janet32766, what did you do?! =p
12:31
<Janet32766>
3 months with no reboot maybe
12:31
<lns>
j/k...but seriously, what happened last that might have caused different behavior?
12:31
so you rebooted and it started doing that
12:32
<vagrantc>
changes in hardware, software ...
12:32
<Janet32766>
no, haven't rebooted in 3 months, but other procs running on there are mission critical, so i can't reboot
12:32
no changes
12:32
<vagrantc>
also useful to know what linux distro and version you're running
12:32
<Gadi>
Janet32766: what distro?
12:32
<Janet32766>
seems like gnome doesn't come up
12:32
7.04 edubuntu server
12:33
<Gadi>
does gnome come up on the server?
12:33
<Janet32766>
i can drive in and reboot tonight, but 50 thin clients are down now at this school and the kids miss their screens
12:33
<Gadi>
log into the server and check your ip addresses - make sure they came up correctly
12:33
<Janet32766>
yes, console is fine
12:34
IP addrs haven't changed in ifconfig
12:34
<Gadi>
ps -ale|grep dhcp
12:34
on the server
12:34
<Janet32766>
dhcp3 is running
12:35
thin clients get IP,and boot login screen
12:35
<Gadi>
ps -ale|grep nfs
12:35
oh ok
12:35
then whats the problem?
12:35
<lns>
Gadi, i think she means it doesn't boot to LDM
12:35
just textmode login
12:35
<Gadi>
oh...
12:36
<lns>
Janet32766, can you verify that?
12:36
<Gadi>
brb
12:37
<Janet32766>
they just get a black screen after login
12:37
<lns>
Janet32766, define "after login"
12:37
is the graphical login coming up or no?
12:37
I.E. ldm
12:37
<Janet32766>
wait
12:38
graphical login workED, until the thin client hardware rebooted, then it stopped also
12:38
but screens came up black upon graphical login, when it did work
12:39
nfsd4 and 8 other nfsd procs are running
12:39
<vagrantc>
so it sounds like gnome isn't working
12:40
<Janet32766>
would that make graphical logins fail after hardware reboot?
12:40* vagrantc watches as apt's default of pulling in recommends downloads everything under the sun into the ltsp chroot
12:40
<lns>
yikes
12:41
<vagrantc>
Janet32766: if the terminals were rebooted without properly logging out, there may be processes running that mess up future logins
12:41
Janet32766: you could test by adding a new user and seeing if they have the problem
12:42* vagrantc nominates "user's not being able to log in with black screen" problem of the month
12:42
<lns>
hahah
12:42
<Janet32766>
there are 200 users, and all of them can no longer log in
12:42* lns votes in secrecy
12:42
<Gadi>
Janet32766: try: sudo ltsp-update-sshkeys
12:43
<vagrantc>
Janet32766: can you create a NEW user, and try to log in with that user. if so, then maybe you have hung processes
12:43
for the OLD users

12:47

in /var/log/messages
12:47

on login, or on logout?
12:47
<Janet32766>
login
12:48
<vagrantc>
sounds like something very wrong with gnome
12:48
if you're getting messages like that when they log in ...
12:48
Janet32766: can you see if there are processes running as those users?

gnome
12:56

12:56

yes
12:56

have you been doing updates?
12:56* vagrantc is confused
12:56

not recently
12:56
<lns>
vagrantc, she means sitting at the server itself gnome works
12:57

it sounds like something's borked at the chroot level..?

i've tried to restart gdm, tftpd, nfs.... anything else?
12:58

sshd ?
12:58
openssh-server
12:58
<Gadi>
Janet32766: sudo ltsp-update-sshkeys
12:59
<vagrantc>
Gadi: if it's logging those gconf messages after each login, it would seem that ldm is connecting and logging in ...
12:59
so i don't think it's the ssh keys ... though if those messages aren't actually happening at each login, it certainly could be ssh keys.
12:59
<lns>
what about kernel inconsistencies? could you have done an update where you have different kernels running on the chroot as you do on the server?
13:00
<vagrantc>
lns: not relevant
13:00
<lns>
oh
13:00
<Janet32766>
ok, i did restart on ssh , and issued ltsp-update-sshkeys.
13:00
<lns>
ok i'll shuttup =p
13:01
<vagrantc>
Janet32766: just to be clear, you get a graphical login screen, and after attempting to log in, you get a black screen?
13:01
Janet32766: and the gconf messages appear in /var/log/messages ?
13:01
<Janet32766>
yes, but then when i hard booted the devonIT thin clients, i no longer get gui login
13:01
yes /var/log/messages
13:02
Dec 10 13:58:52 tma gconfd (roccod-16615): GConf server is not in use, shutting down.

Janet32766: if it's not even booting a kernel, how do you get messages after login?

Janet32766: please, always start at the beginning ...
13:21
<Janet32766>
i'm off site, so all i can to is look at logs and get user reports on phone, but some of the terminals that haven't been power cycled have GUI logins on them, and get the dconf server is not in use msg on attempt
13:21
<Gadi>
oh....
13:21

well, this would affect the VOIP and MS clients, but you can try taking down the firewall and rebooting the clients

(at least to test)
13:51
<Janet32766>
does my iptables pastebin look like it has problems?
13:52
<Gadi>
not sure - you have lots of proying going on - maybe for the IP phones?
13:52
the MASQUERADE line is so your MS boxes can get out to the internet
13:53
your server is playing role as router + NAT fw
13:53

yes on MASQ. no thin-clients makes the kids mad, no VoIP would make the school admin mad :)
13:53

are you sure firehol is not blocking tcp traffic from the thin clients?
13:57
or maybe bandwidth shaping for the VOIP phones?
13:57
maybe its slowing down the download of the kernel
13:58
to QoS the VOIP traffic
13:59* Gadi wonders what iptables looked like pre-reboot
13:59
<Janet32766>
only QoS is on separate router, tc's get DHCP, wouldn't that imply that it's TCP is clear?

I thought you said you rebooted?

14:01

right - but you said this all happened after a reboot
14:01
*started happening
14:02
<Janet32766>
if i power cycle *thin-clients*, i no longer get GUI login

not that i know of. nothing major has changed in months
14:05

well, I have never seen some of your dhcpd.conf params
14:05

that is required for Polycom phones
