hi everyone
05:21
can someone please remind me .. if I make any changes to lts.conf file do I have to rebuild ltsp client?
05:22
all I did was to add xorg.conf file to /opt/ltsp/i386/etc folder and set path to lts.conf to point to that file.
05:23
<exodos>
multik: are you using gutsy?
05:23
<multik>
yes 7.10 on edubuntu
05:24
<exodos>
if you want to keep it in /opt/ltsp/i386/etc you have to rebuild everytime
05:24
but you can also plase lts.conf in tftp dir of ltsp
05:24
<multik>
I don't care where it is as long as I wont have to rebuild ltsp client every single time.
05:24
I have copied lts.conf from it's default location to /tftpboot dir
05:25
damn, still no picture on LTSP client.
05:26
so 7.10 fixed nothing for AMD VGA chipset
05:28
<exodos>
you have to place it in the subdir of /tftpboot where you have initram vmlinux and other stuff
05:28
<multik>
you mean xorg.conf file?
05:28
<exodos>
lts.conf
05:28
<multik>
it is there
05:28
it's in ar/lib/tftpboot/ltsp/i386
05:28
var*
05:29
<exodos>
looks ok
05:29cyberorg has quit IRC
05:29
<multik>
and xorg.conf is in opt ...
05:29
<exodos>
but you have to rebuild the image if you added some files to /opt/ltsp/i386/etc
05:29
<multik>
umm
05:30
<cliebow>
ltsp-update-image
05:30
<multik>
if I type ltsp-build-client it complains that I already have stuff in /i386 folder
05:30
update image, aaah
05:30cyberorg has joined #ltsp
05:31
<multik>
oh my, if you don't know these things, it's pretty complicated :) Thanks man
05:31
<cliebow>
heh..if you watch the packets you will see it will e doenloaded from your tftp dir
05:37
<multik>
watch the packets?
05:48
<cliebow>
use ethereal to capture the packets and analyze them
05:50
<multik>
ah, never done it before
05:51
<cliebow>
it is called wireshark now...tremendously useful
05:52
<multik>
interesting.
05:52
how can I authorize a workstation to connect to LTSP server?
05:52
<cliebow>
sounds like you need to run ltsp-update-sshkeys
05:53
<multik>
you reckon?
05:53
do i have to do it every time I add a thin client?
05:53
<cliebow>
no
05:53
<multik>
once?
05:53
<cliebow>
yes
05:54
<multik>
ok, done, rebooting my thin client
05:54
I added new user to edubuntu server. Do I have to specify somewhere that this user can log in thru thin client?
05:54
<cliebow>
remember this thing develops so fast no one but ogra/sbalneav can keep uip
05:54
i think not
05:55
<multik>
"This workstation is not authorized to connect to this server!
05:55
ogra: you around mate?
05:55
<cliebow>
wierd...yesterday sshkeys fixrd this
05:56
<multik>
i'm just wondering how many ltsp thin client manufacturer use edubuntu? or is it the problem of *ubuntu or ltsp or what the h'''' is wrong.
05:56
I take debian, use their how-to on LTSP, connect my client and it works.
05:56
I wait for 1y for edubuntu or *ubuntu to fix their stuff and still nothing works.
05:57
<ogra>
can you point me to the bugreports ?
05:57* ogra doesnt have any that are open for a year
05:57
<multik>
ogra, hi, what do I have to do to authorize thin client on edubuntu
05:58
I reckon Q-Funk has talked to you about this client. But let's leave it for now.
05:58
<ogra>
sudo ltsp-update-sshkeys && sudo ltsp-update-image
05:58
<multik>
did that already, nothing.
05:58
<ogra>
every time anything below /opt changes you need to run ltsp-update-image
05:58
ltsp-update-sshkeys updates a file in the chroot so -update-image is needed afterwards
05:59
hardy will have gui tools that help you ...
06:00
multik, Q-Funk approached me during gutsy development about that client ... gutsy took 6 months to develop and he didnt talk to me at the start of gutsy ... thats not 1year
06:01
we invested a big load of time to make the LINUXBios stuff boot at all and to my knowledge that works fine now
06:02
<multik>
it doesn't afaik
06:02
I'd like to promote and use edubuntu, but I can't get my clients to boot into it
06:02
<ogra>
well. it does here and for sbalneav
06:02
<multik>
so I'm here to learn from you
06:02
<cliebow>
aqhah..

<cdealer>
hi
06:03
<ogra>
sadly i dont have any time to do big support stuff before the UDS
06:03
<cdealer>
[ogra]:: why im getting workstation not authorized to login ? Im guessing that have anything to do with ssh but dont know hwo to figure out
06:04
<ogra>
i know the LinuxBios stuff does the network boot just fine here, so how do you get the client booted if it doesnt work ?
06:04
(it took several weeks of debvelopment to make that work properly, it would be a shame if the network booting doesnt work for them)
06:05
cdealer, sudo ltsp-update-sshkeys && sudo ltsp-update-image
06:05
you dont have a matching key for the server IP in the client chroot ...
06:05
<multik>
it boots now, I just need xorg.conf to see the GUI login prompt
06:05
<ogra>
so the LinuxBios works, right ?
06:06
<multik>
all I need to know is how to authorize thin client to log in to Edubuntu 7.10 gutsy
06:06
seems to, now.
06:06
<ogra>
your xorg prob is not an ltsp prob ...
06:06
that thing is that the driver itself is broken on autodetection
06:06
<multik>
yes i know
06:06
<ogra>
and id ask you to contact the maintainer fo this driver for a fix ... which is ... uhm... Q-Funk
06:07
<multik>
nope, it's AMD ;)
06:07
Q-Funk aint the manufacturer
06:07
<ogra>
so dont blame ubuntu for breakage we cant influence
06:07
the fact that it works for you in debian is based on debian having 1year old packages in etch
06:07
<multik>
I saw quite a few AMD packages being fetched with I did upgrade, I hoped that VGA issue would be solved as well
06:07
<ogra>
but he's the maintainer
06:08
and your contact to the upstream developer (AMD in tis case)
06:08K_O-Gnom has joined #ltsp

<multik>
ogra, how to authorize client to connect to the server=
06:08
sshkeys doesn't resolve it for me.
06:08
<ogra>
sudo ltsp-update-sshkeys && sudo ltsp-update-image
06:08
<cdealer>
[ogra]:: Hmm I did only the ltsp-update-sshkeys... will do now the ltsp-update-image too =)
06:08
<ogra>
you need to run both in that order
06:09cyberorg has quit IRC
06:09
<multik>
ok
06:09
thanks
06:10
<ogra>
hardy wil make all that easier, promised
06:10
<multik>
ogra can I have a word with you in private?
06:11
<ogra>
sure, but not to long i have some deadlines to match this week and an awful amount of work ahead
06:17cliebow has quit IRC
06:19
<cdealer>
[ogra]:: still doesnt work... "this workstation isn's authorized to connect to server"
06:19
<ogra>
sshd is running ?
06:20otavio_ is now known as otavio
06:20
<cdealer>
sure... im connected here through ssh O.o
06:21
<ogra>
anything intresting in auth.log ?
06:22
<cdealer>
[ogra]:: no.. only my connection that im using from here, nothing from ltsp...
06:23
[ogra]:: Im thinking about build the client again and reinstall the sshd
06:24
<ogra>
no need for that
06:24
<cdealer>
what you suggest?
06:25
<ogra>
check /opt/ltsp/i386/etc/ssh/ssh_known_hosts
06:25
it should contain a line for your IP
06:25
(server IP that is)
06:26
<cdealer>
removing this file wont help ?
06:26
ssh_know_hosts: ltsp-server ssh-dss AAAAB3NzaC1kc3MAAACBAOSuXeQS (...)
06:28Guaraldo has joined #ltsp
06:28
<ogra>
ltsp-update-sshkeys will recreate it
06:28
no ip or anything ? only the hostname ?
06:29
(thats wrong ... there shold be a line for the IP as well)
06:30
<cdealer>
there are 3 blocks like this
06:30
200.xxx.31.55 ssh-dss AAAAB3NzaC1kc3MAAACBAOSuXeQSlEIUAdRafuR5h0ggEts9q0B8iAx6GvTtHA8FITtmWrqoPlnzcPDC+mu91LzRFcwSCHeZu+BFwZ+
06:31
[ogra]:: but this is strange, because the box have to Nic one to the LAN and other directly to the WAN...
06:31
<ogra>
one needs to match the IP the client is connected to
06:32
do you have such an entry ?
06:32
<cdealer>
[ogra]:: just change to the server lan ip will do?
06:32
<ogra>
no
06:32
<cdealer>
I will remove this file...
06:32
O.o
06:32
<ogra>
sudo ltsp-update-sshkeys --export ./ssh.test
06:33
check if ssh.test has a line for that IP
06:33
<cdealer>
now there is
06:33
<ogra>
(removing the file wont help you if the server has no key for the IP)
06:34
<cdealer>
this ssh.test has the server lan ip
06:34
<ogra>
and if you run it without --export it doesnt update the file in the chroot to look the same ?
06:34
(--export is just redirecting what otherwise would end up in the chroot)
06:34
<cdealer>
yeah
06:35
<ogra>
thats a bug ...
06:35
<cdealer>
but I did before like you said... ltsp-update-sshkeys and ltsp-update-image... I will do know again
06:35
the chroot file isnt updated...
06:35
<ogra>
hmm
06:36
copy ./ssh.test over to /opt/ltsp/i386/etc/ssh/ssh_known_hosts
06:36
then run sudo ltsp-update-image ....
06:36
check if it works ...
06:36
then file a bug please :)
06:36
<cdealer>
okay
06:43
[ogra]:: now is working fine =) thanks dude =D
06:44
<ogra>
sorry for the bug though ...
06:44
i wonder whats wrong
06:46
<cdealer>
[ogra]:: is the first time this happen here...

Good morning... anyone out there know of issues with running NFS exports with LTSP? I'm trying to get 2 edubuntu servers to share home folders for users, and it crashes when the home folders are accessed.
08:59
multik: congratulations :)
09:01
<sbalneav>
sonjag: Did you install the package "nfs-client" on the client, and "nfs-kernel-server" on the server?
09:01
<jammcq>
"crashes" in what way?
09:01
kernel panic?
09:01
<sbalneav>
Morning jammcq!

so it just hangs

no errors?

09:05
<jammcq>
hmm
09:05
maybe you need lockd running
09:05
it's been a while since I messed with nfs and file locking
09:05
<sbalneav>
Have you installed the package "nfs-client" on the client.
09:05
<ogra>
why would he need it on the client ?
09:05
<jammcq>
yeah
09:05
<sonjag>
sbalneav: clients are ltsp
09:05* jammcq wonders too
09:06
<sbalneav>
because "nfs-client" package includes libs to do proper locking.
09:06
<ogra>
is that gutsy or feisty ?
09:06
<sonjag>
ogra: I'm running fiesty
09:06
<ogra>
i'm not sure we install nfs-commn in gutsy by default (its not used by anything)
09:06
ah
09:06
<sbalneav>
You're sharing home dirs between two edubuntu servers, right?
09:07
<sonjag>
yes... well, I want to. I want to have 2 servers use dhcp load balancing to share clients. Not running yet because I need to share home folders.

09:08
<sbalneav>
I'll say it a third time.
09:09
Have you installed the package "nfs-client" on the edubuntu machine that's mounting the home dirs?
09:09
<jammcq>
can you even mount an nfs share without the nfs-client package?
09:09
<sbalneav>
because if you don't you'll run into this exact problem.
09:09
yes you can
09:09
<jammcq>
oooooh
09:09
<ogra>
heh
09:09
<sbalneav>
but locking doesn't work
09:09
<jammcq>
well then, I highly suggest doing what sbalneav says
09:10
cuz he's the shiznit
09:10
<sonjag>
sbalneav: [noob here] when I run ps aux | grep nfs, I see about 8 results, some are nfs, some nfsd. None are nfs-client. Am I lookign in the right place?
09:11

09:12
nfs-common is already the newest version.

Specifically, the locking libs
09:16
<jammcq>
how does that not show up with apt-cache ?
09:16
<sonjag>
sbalneav: are you telling me to install that? if so, I've never used aptitude... does it just work? Or do I need to do something. I just use apt.

I have segfault during setup of x11-common while creating ltsp chroot. Clean gutsy install. Can anyone help?
09:16
<sbalneav>
aptitude's the same as apt-get

aptitude install nfs-client
09:17

except it shows things apt-get doesn't
09:17
hmm
09:17

All I know is, for r/w mounts, if I don't install nfs-client, I get exactly the same problems. File locking won't work.
09:18
We never run into it for most things in ltsp, since we mount ro, so locking semantics don't enter into the picture.
09:18

I thought I saw something similar on launchpad, but cannot find it anymore

09:24
<sbalneav>
the NFS server
09:24
For the home dirs
09:25
<sonjag>
sbalneav [noob here] which one is considered the NFS server? The one the export is coming from or the one picking it up?

sbalneav: mish mash (I work at a school) HP 4104gl working as backbone (managed, gig port for server, 10/100 for clients). Clients might jump through other switches possibly SMC, Dlink, Amer.com, but all 10/100 ports.
09:29
<Gadi>
if so, you should try putting the primary into a partner-down state
09:29arkwys has quit IRC
09:29
<sonjag>
gadi: When this problem happened, yes.
09:29
<Gadi>
yeah, you need to go into partner-down
09:29
<sonjag>
Gadi: how do I do that?
09:29
<Gadi>
on the primary, edit: /var/lib/dhcp3/dhcpd.leases
09:29
<sbalneav>
Gadi: I'm also thinking the switch could be blocking udp
09:29arkwys has joined #ltsp
09:30
<sbalneav>
Which would hang the nfs home dir mounts
09:30
<Gadi>
sbalneav: if she's loadbalancing, its probably introducing the prob
09:30
the two servers arent communicating properly
09:30
and are handing out the same IP to two clients
09:30
causing IP conflict
09:30
and the terminals dropping
09:30
<sonjag>
gadi: Don't you mean dhcpd.conf? And what line do you want me to add?
09:31
<Gadi>
sonjag: no
09:31
loadbalancing is a weird beast
09:31
that gets angry and throws things if you don't set it up right
09:31
<sonjag>
gadi: okay, what line do I want to add to leases?
09:31
<Gadi>
sonjag: do you see a stanza like:
09:31
...Gadi gets example...
09:32
damn
09:32multik has quit IRC

<Gadi>
a stanza about the current state and previous state
09:32
I dont have a good example handy
09:33
<ogra>
Gadi, and that can influence gconfd's behavior on nfs mounted homedirs ?
09:33
<sbalneav>
I was understanding that it wan't terminals dropping, but accessing home dirs was hanging
09:33
<Gadi>
(also, when you get a chance, copy the dhcpd.conf's from both servers to pastebot:
09:33
!pastebot
09:33
<ltspbot>
Gadi: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
09:33* ogra is curious how dhcpd affects that
09:33
<Gadi>
ah,
09:33
<sonjag>
gadi: DOH!! This failed when I wasn't using load balancing! Sorry for the confusion. In my fury lately, I isolated the secondary server, and have them running differently. They are on 2 different subnets... could that be an issue? The terms trying to get the export are on 192.168.0.x while the server is on 172.27.x.x
09:33
<Gadi>
if its NFS dropping thats different
09:33
ah, ok
09:34
belay those orders and Gadi returns to the corner
09:34
<ogra>
sonjag, so to understand your setup, you have two servers and one is being used as a fileserver for /home ? and one is client to this ?
09:35
or how did you set it up exactly ?
09:38
<sonjag>
ogra: Mendel (172.27.1.41, doles out 172.27.5.x to 172.27.7.x on eth0) is running LTSP and holds the home folders. Crick (172.27.1.40, doles out 192.168.0.x on eth1 on isolated subnet) is running LTSP and gets home folders from export from Mendel via nfs mount. Crick's terminals are isolated right now becuase I can't get them to work. Eventually, all will be on 172.27.x.x if I can get this home folder issue solved.
09:38
<sbalneav>
brb
09:38
<sonjag>
sbalneav: what is brb?!!
09:38
<ogra>
so you only run one nfs server and one nfs client, right ?
09:39
<sonjag>
ogra: yes
09:39
<ogra>
sonjag, be right back
09:39
not two servers and you crossmount /home between them or so
09:39
(that could become an intrsting loop :) )
09:39
*intresting
09:40
<sonjag>
ogra: no. Only Mendel is exporting. If it matters, they authenticate via winbind and to match UID/GID, I copy idmap from Mendel to Crick nightly. Not elegant, but login is working. However, UID/GID could be problematic so I mention it here.
09:41
<ogra>
yeah that sund like a possible problem
09:41
*sounds
09:42
<sonjag>
ogra: since users are logging in and can get into their home folders, I don't think that's it. Or could this be related to permissions? Is there a way to check?
09:42
<ogra>
no, i remember there once was a bug with hidden dirs (like ~/.gconf) and nfs
09:43
the users are not logged in multiple times i suppose
09:43
<sonjag>
ogra: nope
09:44
<ogra>
http://ubuntuforums.org/showthread.php?t=211529
09:44
smells like the same prob
09:45
looks like http://linuxlab.dk/tipsntricks/gnomennfs.php has a suggestion
09:46
googling "gconfd nfs locking" actually revelas tons of hits
09:46
<sonjag>
ogra: will look at that. Can't try until after school, but will give it a whorl. Also found this <http://linux-nfs.org/pipermail/nfsv4/2005-March/001355.html> which is old but sounds very similar too.
09:47
<ogra>
well, that might rather be broken nfs4
09:47
but could also be the same indeed
09:47
<sonjag>
ogra: nfs4 is running. Is it not ready for production? How do I find these things out?
09:48
<ogra>
that mail was from 2005 :)
09:48
nfs4 should be fine nowadays ... i just meant his specific issue
09:49
http://www.gnome.org/projects/gconf/ aha, look at "I'm having a lock file problem. What do I do?" :)
09:54
<sonjag>
ogra, sbalneav: thanks for all your help! I'll read these sites you reference. Hopefully I'll find a solution.
09:55
<ogra>
if nothing works you can still resort to samba or cifs worst case :)
09:55
but given that many users run such setups it should be solvable
09:56
<sonjag>
Gadi: Thanks for your help. I am planning on running dhcp load balancing. Can you send me info on setting up the partner-down thing you were talking about? Thanks!

sonjag: if you plan on doing loadbalanicing, I suggest reading man dhcpd.conf
09:56
and then lets chat
09:57
it follows a whole long spec, but there are some basic behavior things you need to get used to
09:57
in order to troubleshoot if things go awry
09:57
<sonjag>

don't take that as an rtfm kinda thing

ogra: after reading the posts, I went to install nfslock. It looks like that might be an rpm only app. (tell me if I'm wrong here.) When I looked for similar, I found libfile-nfslock-perl. Any thoughts on this and whether it'll do what I need with locking?
10:26
<jammcq>
sonjag: on your server, run this: rpcinfo -p
10:27
and see if it shows 'nlockmgr' running
10:27
<sonjag>
jammcq: it does... is that similar/same as nfslock?
10:28
<jammcq>
it's the server-side of the nfs locking mechanism
10:28
on the client, I think you need a 'lockd' process running
10:28
but my memory is a bit foggy

sbalneav:csn you give me the ten second description how squashfs replaces nfs mount
10:34
?
10:36
<vagrantc>
cliebow: it's actually a combination of NBD+squashfs+unionfs
10:37
cliebow: NBD (network block device) is used to ... mount a block device over the network ... that contains a sqaushfs image (could easily contain ext2 or whatever fs) ... on top of that unionfs is used to layer the filesystem with a tmpfs mount, so that everything is writeable.

10:44
wasn't nearly as difficult as i'd thought it would be
10:44
<ogra>
cool
10:44
i havent started hardy at all yet, feel free to go forward as you like :)
10:45
i'm planning the merge and branch creation in boston with scott at my side
10:45
<vagrantc>
most likely i'll try and get an upload to debian experimental ...
10:45
ogra: i just merged gutsy into my debian branch and should do an upload this week
10:45
<ogra>
so apparently we still use unionfs 1.4 in ubuntu since 2.0 is to buggy ...
10:45
<vagrantc>
not much different
10:46
ogra: that's why i haven't been able to get it to work in debian ?
10:46
<ogra>
so we'll likely never see debian using the squashfs way
10:46
yeah
10:46
<vagrantc>
at least, not until it's fixed
10:46
<ogra>
unionfs 2.x is pretty odd
10:46
i dont think it will get fixed
10:46
<vagrantc>
ogra: i did try NBD+squashfs+tmpfs mounts and it also proved unstable.
10:47
<ogra>
i mean ubuntu is poking upstream since it exists about this stuff
10:47
we had quite bright people working on the bugs and they didnt manage ...

sonjag: ubuntu gutsy is using NBD+squashfs+unionfs instead of NFS+tmpfs mounts
11:25
sonjag: sounds faster, but i haven't gotten it to work on debian
11:25
<sonjag>
vagrantc_ so if I update, will I need to rebuild it? doh, just read that you don't have it working. I'll stay fiesty and mount with nfs :)
11:26

sonjag: it is working on ubuntu gutsy, so i hear, but just not on debian
11:26

you need to rebuild
11:26

Hi. I am having a huge delay in the LTSP boot process (LTSP5, Ubuntu Gutsy), which takes several minutes. Syslog shows a lot of nbd errors on the client (attempt to read on closed socket). Does anyone hava any idea what may be causing this?
12:39
<sbalneav>
Sounds like the nbd server process is dying, or having trouble
12:39
either that, or you're dropping packets on your network
12:40
Check your cabling, hubs, network cards for interrupt conflicts, etc.
12:40
<|jraf|>
Good idea. I'll try to swap the server ethernet interface.
12:42
However, I did not have any problem while using the same number of clients on LTS 4.2, with nfs root, and with the same server. Does ndb increase the network usage or is more sensitive to dropped packages?
12:42
packages = packets ... :-)
12:43
<ogra>
it lowers the network usage (a lot)
12:43

Anyone have a link to the Scott Balneaves LTSP FISL video? from Sofware Livre in Brazil?

hey, take me with you !
12:56
<jcastro>
ok
12:57
<ogra>
we should don a #ltsp meeting one evening :)
12:57
<Blinny>
Beer is good.
12:57
<ogra>
*do
12:57
<sbalneav>
Beer is always good.
12:58* ogra didnt want to stop a tete-a-tete from happening though
12:58
<ogra>
so just ignore me :)
13:00
<sonjag>
I'm in for it. Anyone in New England? I'll teach you all to use nano (that's for sbalneav :)
13:00* sbalneav sets +I for ogra :)
13:01
<ogra>
many of us will be in boston next week
13:01
<sbalneav>
Don't need to know nano.
13:01
I know a *real* editor already.
13:01

I have two persistent problems that I've never been able to nail down. The first is gnome applets failing every now and then. Usually when logging in via NX, or after an ungraceful exit of gnome.
13:06
<ogra>
bah ...
13:06
they are only pimped ed
13:07elisboa has quit IRC

Blinny: sounds like a similar issue I have on a box due to bonobo-server not dying upon logout
13:08
which stems from a bug in evolution
13:08
amongst other apps
13:08
<Blinny>
Gadi: Hrm. I use neither.
13:08
<Gadi>
when a user logs out, do you see lingering processes?
13:08
<Blinny>
I haven't checked that..
13:08
<ogra>
i guess Gadi means evolution-data-server (has nothing to do with evo apart from the name)
13:08
<Gadi>
see if they do
13:08
<sbalneav>
jammcq: Well, if you typed your code *CORRECTLY* the first time, you wouldn't need sed, now would you? :)
13:08
<Blinny>
Okay.
13:08
<Gadi>
ogra: right

sorry

e-d-s is used by the calendar and time applet in gnome

its all a bag of mixed up messed up gnome yummy problems
13:09
<Blinny>
Is there a way around them, other than upgrading? (;
13:09

no mater if you use evo ...

I am using the process purging when a user logs in/out
13:10
<Gadi>
Blinny: not sure - haven't found a way yet
13:10
<Blinny>
I assume my 2nd problem has to do with this
13:11
(this is an Eric K12-specific hack though I think)
13:11
<Gadi>
Blinny: are you on LTSP 5 or 4?
13:11
<Blinny>
4.2
13:11
K12v6
13:11
<Gadi>
ah, then it may or may not be related
13:11
<Blinny>
heh
13:11
ok
13:12
<Gadi>
still check for the lingering processes

The second is, also usually after an ungraceful gnome edit, a user will get what looks like a confirm box after putting in their login/password, but the box is filled with unprintable characters, and the two buttons also are. They look like squares all over the confirmation. - Pressing enter or escape will let them log in, but the next time they log in they'll get the same thing. Clicking the right of the two squared-out buttons returns the user to log
13:13
<ogra>
i'd bet on dbus not exiting with the session
13:13
<Blinny>
I assume this is 'you're already logged in, do you want to kill your previous login?'
13:13
<ogra>
and all dbus apps hanging in wait state

Blinny, there is a font missing ...
13:14
<Blinny>
Yeah, I figured. Or corrupted.
13:14
<ogra>
apparently you see an untranslated string there
13:14
<Blinny>
Is that in gdmgreeter?
13:14
<ogra>
no idea
13:14
<Blinny>
Fun.
13:14
I've seen that box before I think, but it was printed characters.
13:14
(readable)
13:15
<ogra>
probably something custom thats started on ligin as first app ...
13:15
*login
13:15
probably gdmgreeter ...
13:15
<Blinny>
Where would I investigate that?
13:15
<ogra>
we dont use gdm anywhere :) i could tell you where to look in ldm :)
13:16
<Blinny>
gdm was used in 4.2 though yes?
13:16
<ogra>
XDMCP was
13:16
4.2 didnt ship a login manager
13:17
<Blinny>
Ah.
13:17
<ogra>
so whatever your X server connects to :)
13:17
<Blinny>
Do you know of an XDMCP or gdm config file location?
13:18
<Gadi>
Blinny: /etc/gdm/gdm.conf (or /etc/X11/gdm/gdm.conf)
13:19
<Blinny>
I have an /etc/gdm/custom.conf
13:19
Again, maybe a k12-specific thing
13:19
<Gadi>
dont mind ogra - he just tries to copy the look and feel of gdm ;)
13:19elisboa has joined #ltsp

nah, thats probably a fedora thing

do you use a font server?

13:21
xfs is running ...
13:21
<Gadi>
there ya go
13:21
<Blinny>
though I'd rather not. I've never understood the font server thing
13:21
<Gadi>
do you have USE_XFS in your lts.conf?
13:21
<Blinny>
=N
13:22
xfs is running on the server, mind
13:22
<Gadi>
so, its running, but you dont use it?

Gadi: Would it be used by local logins at the server's console?
13:23
Gadi: I've never understood how to _stop_ using it.
13:23
When I've disabled on my home PC, X won't start.
13:24
<ogra>
remove it from xorg.conf
13:24
<Blinny>
But that's just stopping the service; I don't know how to stop X from
13:24
Oh.
13:24
<ogra_cmpc>
you might have a unix domain socket entry in teh font path settings
13:25
<Blinny>
Change FontPath "unix/:7100" to some local parh?
13:25
*nod*
13:26
<ogra_cmpc>
just comment it
13:26
there should be other local paths
13:26
<Blinny>
Do I need to yum install xorg-x11-fonts*
13:26
<ogra_cmpc>
no idea
13:26
<Blinny>
heh
13:26* ogra_cmpc has no clue about RH package names
13:27
<Blinny>
There is a /usr/share/fonts and /usr/share/X11/fonts filled with pcf files
13:27
...but again, this is all on the server, not the clients. Is this just symantics or does this have to do with the funky-joe message I'm getting on the thin clients (recall USE_XFS=N)
13:29
There are no other entries for FontPath in my server's xorg.conf
13:30bobby_C has quit IRC

13:32|jraf| has quit IRC
13:32
<Blinny>
Well.
13:33
How about if I try this on my home computer first. I'll change FontPath to /usr/share/X11/fonts, stop xfs and see how it runs
13:33
If that works, then I'll try it here on my LTSP server
13:33
(but I don't see how that matters if the thin clients aren't using XFS
13:34
The thin client I'm on have four or five entries on FontPath, none of this ware a domain socket
13:36
And, there isn't a corresponding package outside of the chroot - there is no /usr/X11R6/lib/X11/fonts on the server

option root-path "/var/lib/tftpboot/ltsp/i386/i386.4.1"; ??? Shouldn't it be option root-path "/ltsp/i386/i386.4.1"; ???
13:57
<cliebow__>
i should think if it is /etc/exports the filesystem could be anywhere...
13:58
the prob with this client is the kernel must be in same dir as rootfilesystem
13:58
<Blinny>
It's relative to tftpboot
13:58
<cliebow__>
so kernel has to be below /var/lib/tftpboot
13:58
<Blinny>
I believe so, yes.
13:59
<cliebow__>
so then rootfilesystem for this client has to be below /var/lib/tftpboot
13:59
<Blinny>
If your problem is correct, then yes.
13:59
Why?
14:00
<cliebow__>
idiosyncracy of these old clients
14:00
they do not pxeboot (or etherboot)

yeah, try plugging in an external monitor, or a projector
21:27
see the real goodness that we've all been waiting so long for
21:27

just awesome with xrandr 1.2

I am starting to write a script to monitor every few seconds to see if the external was unplugged and switch back to single head mode
21:29
This is realy very nice
21:30
<jammcq>
I think that's supposed to cause a udev event

which could trigger a rule to do something
