<johnny>
so.. what cli utility can execute a .desktop file?
00:29
kinda wondering how we can provide a list that can override the Exec on a per user basis
00:29
such as to prepend our local apps starter
00:33
<vagrantc>
we'll see it when we see it.
00:37
<warren>
starter?
00:37
sent mail to ltsp-devel
00:38
<johnny>
hmm.. warren.. i'm not sure you're gonna like our current patterns..
00:38
genkernel-$arch-$name
00:38
<warren>
johnny: are your patterns based on gentoo's standard pattersn?
00:38
johnny: what do your arch names look like?
00:39
<johnny>
there is no gentoo standard pattern, unless genkernel is used;which it is by default for ltsp kernels anyways
00:39
but there is no standard gentoo pattern
00:39
<warren>
whaaaa
00:39
that makes little sense
00:39
<dberkholz>
what?
00:39
<warren>
dberkholz: see ltsp-devel
00:39
johnny: the code I had in mind, might be difficult to have an $arch in the name...
00:39
<johnny>
warren, ltsp we are using gentokernel
00:40
<warren>
johnny: what do your arch names look like?
00:40
i386?
00:40
x86_64
00:40
ppc
00:40
ppc64
00:40
etc.
00:40
<johnny>
x86,amd64,ppc,pp64,x86bsd
00:40
<dberkholz>
x86, amd64, ppc, sparc, etc
00:40
<warren>
argh
00:40
<johnny>
sparc
00:40
<warren>
your arch names are different from glibc
00:40
<johnny>
setarch will provide the proper names tho
00:41
<dberkholz>
http://sources.gentoo.org/viewcvs.py/gentoo-x86/profiles/arch.list?view=markup has the full list
00:41
<warren>
I mean, your archnames in those patterns will be different from glibc
00:41
johnny: please reply to my message with concrete examples of what your files look like
00:42
perhaps I need to make the clenaup script not mandatory...
00:42
<johnny>
i wouldn't mind it ...
00:42
to have it i mean
00:42
<warren>
yeah, but your patterns are very screwballish
00:42
johnny: oh
00:42
<johnny>
uggh.. lemme try again
00:43
<warren>
johnny: in our case arch is included within $NAME
00:43
<johnny>
your cleanup script is a good idea
00:43
<warren>
johnny: vmlinuz-2.6.25.14-108.fc9.i586
00:43
johnny: /lib/modules/2.6.25.14-108.fc9.i586
00:43
is arch within $NAME?
00:43
in your case?
00:43
<johnny>
no..
00:43
<warren>
could you make it?
00:43
=)
00:43
that simplifies things a lot
00:43
and in general it makes it easier for the distro to debug stuff...
00:44
<johnny>
i think just using whatever is in /lib/modules as a pattern would work
00:44
<dberkholz>
here's what i've got for a kernel name: kernel-genkernel-x86-2.6.25-gentoo-r7. then there's lib/modules/2.6.25-gentoo-r7
00:44
<warren>
what are the actual filenames that get dumped into /var/lib/tftpboot/i386 ?
00:44
<johnny>
what he said and initramfs-genkernel-26.6.25-gentoo-r7
00:45
err.. not 26 :)
00:45
not yet :)
00:45
<dberkholz>
initramfs-genkernel-x86-2.6.25-gentoo-r7 is what i have
00:45
with the arch tagged in there
00:45
<warren>
sigh
00:45
you should really consider adding arch to $name
00:45
=)
00:45
<johnny>
why not just use the pattern as whatever is in lib/modules ?
00:45
<warren>
seriously
00:46
johnny: because it would still be missing the arch
00:46
<johnny>
sure.. but a simple regex would solve that
00:46
<warren>
so you're OK with
00:46
rm -f initramfs-genkernel-*-$NAME
00:47
as long as you're OK with wildcards, then I'll add it.
00:47
anyway, reply to that mail
00:47
<johnny>
dberkholz, any reason why we wouldn't be ok?
00:47
<warren>
i'm heading to sleep
00:47
<dberkholz>
cross-arch support is basically nonexistent, and even if it did exist, i'd be fine with updating them all at once
00:47
<johnny>
i don't see why it matterse.. i don't see how an entire chroot isn't going to be tied to an arch
00:47
err tied to more than one arch
00:48
<dberkholz>
64bit kernel, 32 userland
00:48
weird but done
00:48
anyway, bed for me too
00:48
<warren>
fedora servers could host several archs...
00:48
ok night
00:48
reply to my mail
00:48
i need those patterns in records
00:49* johnny thinks every group needs a warren.. keeps us on our toes :)

hmmm... well, looks like i figured out how to configure rsyslog for remote reception ... i must not have had it working client-side last time i tried.
01:48
seems to be much slower than remote syslogging used to be ... the kernel logs take forever...

Hello. Is there any redundacy setup possible when using LTSP5? Which direction should I look for a solution that lets me replace a failed LTSP server in realtime (maybe w/o clients noticing at all)?
05:03
<ogra>
google for milleXterm
05:03
they build such stuff on top of ltsp5
05:04
<vlt>
ogra: Thanks

<cyberorg>
ogra, was ldm shutdown behavior finally changed to use normal shutdown?
05:19
<ogra>
cyberorg, i want it to be telinit <runlevel>
05:19
but that hasnt happened yet
05:20
<cyberorg>
ok, telinit should work here too, using that would probably help doing clean umount of nbdroot for us

<wathek>
hello all
05:25
I've a DHCP server that gives IP to my network clients and is it possible to install LTSP in an other computer and to disable the DHCP ? so my DHCP server gives the IP and then my second Server will be the LTSP ?
05:25
<ogra>
you need full access to the existing dhcpd to set it up for netbooting
05:26
<wathek>
ogra, ah !
05:26
<ogra>
(i.e. you need to be able to change the config there)
05:26
<wathek>
it's my acess point !
05:26
<ogra>
if it can do netbooting ....
05:26
<wathek>
ogra, my access point that gives IP to the netwrok
05:27
<johnny>
you're prolly gonna have to disable it there
05:27
<ogra>
alternatively have a server with two NICs (which s also our propsed setup)
05:27
<johnny>
or that :)
05:27
<ogra>
or disable it on the AP like johnny says and use just the ltsp server's dhcp
05:27
<wathek>
there are no netbooting options in my AP
05:27
yep gonna do that
05:29
it takes a while ltsp-build-client command !
05:29
<ogra>
indeed
05:30
<wathek>
:)
05:31
is it possible to install the system after netbooting on it ?

10:17
any help please ?
10:18
<ogra>
#
10:18
subnet 192.168.1.0 netmask 255.255.255.0 {
10:18

10:18
range 192.168.0.100 192.168.0.200;
10:18

10:18

10:18
<wathek___>
oops
10:18
I forget to change that
10:19
ogra, same problem
10:19
it fails to start
10:19wathek___ is now known as wathek
10:20
<ogra>
but you have set up a static interface in the 192.168.1.0 network ?
10:20
<wathek>
sure
10:20
<ogra>
and its up and running ?
10:20
<wathek>
ogra, my LTSP has 192.168.1.50 ip
10:21
<ogra>
well, then the dhcpd should work if everything in your config is set up for 192.168.1.
10:21
what distro is that ?
10:21
<wathek>
ubuntu
10:21
Hardy Heron
10:22otavio has quit IRC
10:22
<ogra>
and you change the file in /etc/ltsp/dhcpd.conf, right ?
10:22
<wathek>
yes
10:22
<ogra>
can you put the output of ifconfig -a to the pastebot ?
10:22
!pastebot
10:23
<ltspbot>
ogra: "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.
10:23
<ogra>
and did you chaneg anything else ?
10:23
apart from the dhcpd.conf ?
10:23
<wathek>
ok
10:24
ogra, gimme a sec please
10:24
<ltsppbot>
"wathek" pasted "eth0 Link encap:Ethernet HWadd" (18 lines) at http://pastebot.ltsp.org/48
10:24
<wathek>
;)
10:24
<ogra>
that looks ok
10:25
you fixed the range option in dhcpd.conf ?
10:25
<wathek>
ogra, I'm reconfiguring dhcp
10:25wathek__ has quit IRC
10:25
<wathek>
option routers is for the gateway ?
10:25
<ogra>
??
10:25
reconfiguring ?
10:26
routers doesnt patter for starting it
10:26
*matter
10:26
<wathek>
shit !
10:26
<ogra>
and wont have any effect for the thin clients
10:26babyhuey has quit IRC
10:26
<wathek>
ogra, it doesn't start !
10:27
<ogra>
what exactly did you do now ?
10:27
<wathek>
ogra, this is what I did :
10:27* ogra wonders why wathek didnt just pick the right IP for the interface as the howto says
10:28
<ogra>
instead of poking around in the dhcpd.conf
10:28
<wathek>
ok gonna try some thing else
10:28
<ogra>
what exactly did you do until now ?
10:28
<wathek>
gonna follow the howto
10:28
ogra, this is my dhcp config file
10:28
<ogra>
thats a bit late now
10:28
so lets see that we get the messed up setup right
10:29babyhuey has joined #ltsp

<ltsppbot>
"wathek" pasted "ddns-update-style none; option" (16 lines) at http://pastebot.ltsp.org/49
10:29
<wathek>
that's it
10:29
<ogra>
urgh
10:30
that doesnt look at all like the default ltsp file
10:30
<wathek>
yes I wanted just to get a working dhcp server
10:30
and then adding what ltsp need
10:30
<ogra>
!ubuntu
10:30
<ltspbot>
ogra: "ubuntu" is a Debian based GNU/Linux distrubution that includes a Ubuntu specific version of LTSP. It can be found at http://www.ubuntulinux.org. to install ltsp on ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
10:30
<ogra>
if you had followed the QickInstall guide ....
10:31
anyway
10:31
that setup should still work with the interface as you have set it up
10:31
unless you changed any other stuff
10:31
<wathek>
no
10:32
<ogra>
put these into the subnet declaration:
10:32
option domain-name "east.org";
10:32
option domain-name-servers 193.95.66.10;
10:32
and wipe the rest
10:32
(eevrything above "subnet")
10:32The_Code has joined #ltsp
10:33
<ogra>
oh, they are in the subnet declaration anyway
10:33
so just wie the stuff at the top
10:33
<wathek>
ok
10:33
<ogra>
whats the error you get in the logfile ?
10:33Subhodip has quit IRC
10:34
<ogra>
keep the "authoritative;"
10:34
<wathek>
ogra, what's strange is that in the /var/log/messages there is nothing
10:34
<ogra>
there should be
10:34
anything in syslog or daemon.log ?
10:34
<wathek>
ah it's in the syslog
10:36
Aug 21 17:26:35 Wathek dhcpd: No subnet declaration for eth0 (192.168.1.50).

je pourrais copier ce fichier a la place de mon fichier ?

oops sorry
10:43
ogra, so ?
10:44
<ogra>
that all looks fine
10:45
CONFIG_FILE=/etc/ltsp/dhcpd.con has an f at the end i suppose
10:46
and the file you edited and psted is also definately /etc/ltsp/dhcpd.conf right ?
10:46Subhodip has joined #ltsp
10:46
<wathek>
ogra, yes
10:46
that's that
10:46
ogra, sorry
10:46elisboa_ is now known as xforce
10:46xforce is now known as elisboa
10:46
<wathek>
the file I pasted was /etc/dhcp/dhcpd.conf
10:46
<ogra>
aha
10:46
:)
10:46
then it cant work
10:47
/etc/ltsp/dhcpd.conf overrides that
10:47
<wathek>
ah cool then
10:47
ogra, do I've to reconfigure that file ?
10:47
<ogra>
open it with vi
10:47
<wathek>
done
10:47
<ogra>
type:
10:47

hi, channel
10:48
<wathek>
it started
10:48
<ogra>
cool
10:48
<wathek>
alright let's try LTSP now
10:48
<ogra>
if you make any odifications, be careful ;)
10:49
<wathek>
cool it detects my dhcp server
10:49
<dumpzk>
my name is daniel, come from a college from the philippines. i am considering deploy edubuntu at our college.
10:49
<ogra>
cool
10:50
<dumpzk>
i am looking for some advices on choosing terminal station, any idea ?
10:50
<ogra>
https://wiki.edubuntu.org/HardyClassroomServer
10:50
<wathek>
ogra, it says TFTP open timeout !
10:50
<ogra>
wathek, do you have any other dhcp server in that network currently running ?
10:50
<wathek>
no
10:51
ogra, I stopped my AP DHCP server
10:51
<ogra>
and did you run ltsp-build-client ?
10:51
<wathek>
yes
10:51
<ogra>
ls /var/lib/tftpboot/ltsp/i386
10:51
does that contain any files ?
10:51
<dumpzk>
may i ask a very basic question ? is it possible to use a same config for thin client using diffrent cpu arch, and diffrent video card ?
10:52
<wathek>
ogra, yes it contains the vmlinuz and the inittrd and many other files
10:52
<ogra>
grep tftp /etc/inetd.conf <- does that return a line not starting with # ?
10:52
<dumpzk>
coz, our budget is very tight, we are considering to ask donation from the community
10:52
<wathek>
yes
10:52
<ogra>
dumpzk, configure the videocards during boot
10:52
<wathek>
ogra, it's ok no # in the beginig
10:52
<ogra>
*it confgures
10:53
<dumpzk>
but not sure will diffrent pc can work together on a same network .
10:53
<ogra>
if its all PCs it will just work
10:53
<dumpzk>
orga, do i need to config it everytime it boot ?
10:53
<ogra>
ltsp does that automatically
10:53
<dumpzk>
do the config on every computer ?
10:53
<ogra>
but yes it does that every boot ... you dont need to do anything
10:54
its all automatic
10:54
<dumpzk>
so, zero administrative tasks ?
10:54
set and forget ?
10:54
<ogra>
for 90% of the hardware, yes
10:54
for the 10% where it doesnt work you can manually set up configs if you need
10:55
<dumpzk>
manually set is ok, can it be saved on the server ?
10:55
<ogra>
yes
10:55
it must be saved on the server :)
10:55
<dumpzk>
cool, thanks a lot ogra.
10:55
<ogra>
if you run into any problems, drop by here, we can help
10:56
<dumpzk>
and we will have some cash donation coming in, do you think we should buy dedicated think-client terminal station ? or pc ?
10:56
<ogra>
wathek, try rebooting the ltsp server
10:56
dumpzk, you can get thin clients vers cheap on ebay, i would put as much money into the server as yu can
10:56
Ram is essential
10:57
s/vers/very
10:57
<dumpzk>
which brand and model do you suggest ?
10:57
for thin clients
10:57
and how cheap it should be ?
10:58
<wathek>
ogra, it's ok I had to change the config file of tftp
10:58
:D
10:59
it works now
10:59
:D
10:59
<ogra>
good :)
10:59
<wathek>
ogra, the kernel has been loaded
10:59
<ogra>
dumpzk, something like 500Mhz/128M should be fine
10:59
<wathek>
I get the Ubuntu booting screen
10:59
:D
11:00
ogra, thanx a lot guy
11:00
it doesn't boot
11:00
<ogra>

11:01
<wathek>

hmm
11:02
is your image there ?
11:02
(in /opt/ltsp/images )
11:02
<wathek>
which one ?
11:03
ah I suppose so
11:03
there's i386.img
11:03
<ogra>
ok
11:03
<wathek>
159 Mo
11:03
<ogra>
grep nbrdootd /etc/inetd.conf
11:03
err
11:03
grep nbdrootd /etc/inetd.conf
11:04
<wathek>
2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img
11:04
<ogra>
looks fine
11:06
edit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and drop splash from the line
11:06
that will give you more info abotu the bootprocess and show possible errors
11:07
<wathek>
ok
11:07
ogra, I reboot the client
11:09
ogra, alright
11:09
so
11:10
it shows me the Ip-Config of eth0
11:11
the address, broadcast, netmask, gateway, dns, dns1 and domain
11:11
<ogra>
then it should negotiate the nbd setup
11:11
<wathek>
and it says rootserver : 192.168.1.50 rootpath : /opt/ltsp/i386
11:11
filename : /ltsp/i386/nbi.img
11:12
and after that it says Error : Connect : connection refused
11:12
<ogra>
aha
11:12
<wathek>
and can't mount the /rofs and /root/dev and /sys/ and /proc
11:12
<ogra>
your nbdrootd doesnt start by whatever reason
11:12
<wathek>
it says no Such File or directory
11:12
<ogra>
thats only fallout of the first error
11:12
<wathek>
nbdrootd
11:13
<ogra>
Error : Connect : connection refused is the one you want to fix
11:13
<wathek>
yes
11:13
<ogra>
is your inetd running ?
11:13
<wathek>
let me check
11:14
ogra, there's something strange
11:14
#<off># tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp
11:14
<ogra>
thats definately wrong
11:14
<wathek>
ogra, that's in my /etc/inetd.conf
11:14
<ogra>
did you install any non standard inetd ?
11:14
by default ubuntu uses openbsd-inetd
11:15
<wathek>
ii openbsd-inetd 0.20050402-6 The OpenBSD Internet Superserver
11:15
ii update-inetd 4.27-0.6 inetd.conf updater
11:15
I've the default inetd
11:17
ogra
11:17
look at this
11:17
<ltsppbot>
"wathek" pasted "tux@Wathek:/opt/ltsp/images$ s" (8 lines) at http://pastebot.ltsp.org/50
11:17
<ogra>
thats fine
11:18
we dont use the nbd-server config, dont start it by hand
11:18
images are served by nbdrootd
11:18
<wathek>
ogra, I stop it then ?
11:18
ogra, I've no nbdrootd !
11:18
<ogra>
you have ltsp-server installed :)
11:18
so you have nbdrootd
11:18
<wathek>
yes
11:19
<ogra>
/usr/sbin/nbdrootd
11:19
<wathek>
it's ok
11:19
I got it
11:19
<ogra>
you even had the inetd.conf entry for it
11:19
<wathek>
yes
11:20
<ogra>
i really wonder where that /srv/tftp line comes from in your inetd.conf
11:20
you obviously get tftp though
11:20
else it wouldnt boot that far
11:20
<wathek>
ogra, I've installed tftp and then I uninstalled it
11:20
<ogra>
tftp ot tftpd ?
11:20
*ro
11:20
<wathek>
tftpd
11:20
<ogra>
gah
11:21
*or
11:21
:)
11:21
<wathek>
so it's ok I think !
11:21
<ogra>
right, you get beyond tftp with your boot
11:21
<wathek>
yes
11:21
<ogra>
did you reboot the server as i asked before ?
11:22
<wathek>
ogra, which server ?
11:22
<ogra>
<ogra> wathek, try rebooting the ltsp server
11:22
<wathek>
ah ok
11:22
<ogra>
(17:56 my time)
11:22
<wathek>
lol
11:22
:p
11:24
ogra, I've no deamon of ltsp in /etc/init.d
11:24
!
11:24
<ogra>
but you know what reboot means ? :)
11:24
there is no daemon for ltsp :)
11:24
<wathek>
all the server ?!
11:24
<ogra>
right
11:24
<wathek>
lol I used to reboot only demons ok
11:25
so be right back gonna reboot all the server
11:25
;)

11:35
thanx a lot guys
11:35
guy

11:35
<ogra>
:)
11:35
the services somethimes dont come up properly if you install it manually and not from the CD ...
11:36
<wathek>
ah ok
11:36
ogra, juste one last question
11:36
ogra, how about the users ?
11:36
<ogra>
i havent found out why yet, but rebooting the machine usually fixes it
11:36
create them with the gui tool on the server
11:36
and make sure to allow them to use local devcies in the second tab
11:37
<wathek>
ogra, the gui tool you mean ltsp-manager ?
11:37
<ogra>
no
11:37
<wathek>
so ?
11:37
<ogra>
ltsp-manager is only a proof of concept app
11:37
dont bother trying to use it ...
11:37
the tool the dektop has in the system menu
11:38
<wathek>
ah only adduser
11:38
ok
11:38
<ogra>
system->administration->users and groups
11:38
not adduser
11:38
use the gui
11:38
<wathek>
ok I'm not used to use the gui
11:38
:p
11:38
<ogra>
or fiddle with missing grups manually
11:38
the gui is prepared to have all groups you need
11:39
and has easy checkboxes to enable or disable stuff for the user
11:39
but indeed ouy can use adduser
11:39
and add the user to the fuse group then
11:39
<wathek>
yeqs
11:41
ogra, and I've to add the user to wich groups ?
11:41
nbd ?
11:41
<ogra>
adduser will add the default groups ...
11:41
additionally you need the fuse group
11:41
that should suffice
11:42
<wathek>
ok
11:42
ogra, I reboot the client and retry
11:42
:D
11:42
<ogra>
no need to reboot the client
11:43
<wathek>
ah ok
11:43
no problem it's rebooting

for example the hard disk

USB keys, CDroms and audio are supported atm
11:56Subhodip has quit IRC

and no hard disk ?
11:57
<ogra>
all removabe devices
11:57
if you have an external HDD that will work
11:57
for inetrnal HDDs you need to edit udev
11:58
(the ltsp rules in the chroot ... and then rebuild the image)
11:58* ogra needs to go now
11:58

ogra: do you know what is the ebox model number that corresponds to the LTSP Term 1000?
13:09
<etyack>
warren: ebox 2300
13:09* Lns anxiously awaits the arrival of his LTSP Term 1220 pxe
13:09
<warren>
etyack: i'm getting complaints that LTSP > 4.2 is WAY slower
13:10
etyack: I don't know what changed
13:10
<etyack>
warren: on the 1000?
13:10
<warren>
etyack: I never used 4.2 for many years now, but I find it hard to believe that the ebox is usable
13:10
<Lns>
warren: i've heard in multiple places this is the case with the ebox...not sure which model though
13:10
<jammcq>
on 4.2, the ebox was plenty fast
13:10
on 5.0 is was dog slow
13:11
<warren>
after waiting a few minutes to boot, X is really really slow
13:11
<etyack>
warren: it is "usable" on 4.2 and noticeably slower
13:11
did they disable ssh?
13:11
<warren>
etyack: btw got my follow up mail? did it work?
13:11
<etyack>
warren: got the email, been tied up with other issues
13:11
<warren>
etyack: fedora has LDM_DIRECTX by default
13:11
<etyack>
ohh
13:12
<warren>
something else in the kernel or X changed making it way slower I guess
13:12
but we're literally talking YEARS in vintage difference from 4.2 to modern
13:14
<sbalneav>
I think it's the udev differences.
13:14
It hangs for a long time on udev.
13:14
<warren>
was X performance better in 4.2 as well?
13:14
<sbalneav>
4.2 had a very minimal ruleset on udev
13:14
<warren>
or it only booted faster?
13:14
<etyack>
we are not recommending the 1000 for 5.0 except for limited environments
13:15
x faster and booted faster in 4.2
13:15
<sbalneav>
The ebox did OK once it was booted.
13:15
it just took a lot onger to boot.
13:15CBCradioeng has joined #LTSP
13:15
<warren>
today it takes long to boot, and X performance is unusable
13:15
the latter can't be udev
13:16
<sbalneav>
That'll probably be some change to X drivers then.
13:16
I'm not sure what kind of video chip it had in it.
13:16
<warren>
sis of some sort
13:16
sis native driver works with F8+
13:16
<sbalneav>
sis is very poorly supported in X now.
13:16
<warren>
RHEL5 sis driver didn't support it
13:17
F8+ has native alsa sound working on it too
13:17
it is just too slow
13:22
<sbalneav>
I remember I timed it at one point. It spent a whole 45 seconds of boot time in udev, whereas in 4.2, it was more like about 2 seconds.
13:22
I shaved it down considerably (about 15 seconds) by just removing udev rules related to storage.
13:24
<warren>
we could have a LDM_UDEV_HACK option
13:24
that bind mounts blank files on top of udev rules
13:24
=)

i had the idea this morning ... why don't we handle the ssh session closing just like we do for the login SENTINEL ...
14:18
instead of tacking on "kill -1 $PPID" we tack on something like "echo ALLDONEWITHLTSPSESSION" or such
14:18
and then kill the session once we recieve that
14:19* vagrantc just emailed ltsp-developer about it
14:22
<sbalneav>
Well, we don't watch stdout on the X session ssh, only on the initial ssh connection.
14:22
Wonder if it's something pulse related hanging it up?

sbalneav: is there a reason not to watch stdout on the Xsession ssh ?
14:31Q-FUNK has quit IRC
14:34
<sbalneav>
Umm, well, up until now, we haven't needed too :)
14:35
<vagrantc>
it seems like a potentially cleaner way to handle it ...
14:35
the issue of the ssh connection getting hung by *some* X process using the tunnel has been with me since 2003 or so...
14:36
we could track down the specific application, fix it ... and then a year down the road, something else will crop up.
14:36
<sbalneav>
true.
14:36
how about this.
14:37
Xsession ; xprop -set LTSP_SESSION_DONE or something, watch for the X prop, and ssh -O exit from that?
14:37
<vagrantc>
sounds resonable as well.
14:37
sbalneav: you love them x properties :)
14:37
<sbalneav>
Hmmm, in fact the new xwaitfor thing we did will work PERFECT for that, since it silently sits and waits.
14:38
hey, they're encrypted if the ssh encryptions up.
14:38
<vagrantc>
and now's the moment where it belongs in a separate project :)
14:38
<sbalneav>
heh
14:39
I'll put some thought to it this weekend. That might be a relatively elegant solution.
14:40
I'd still like to know WHAT's hanging it up, if for nothing else than curiosity's sake.
14:44
<vagrantc>
sure. and getting it fixed is probably a good thing.
14:44
although for me, openssh 5.1 clearly seems to have fixed the issue.
14:44
but with 4.7, it's broken. very repeatable.
14:45
although i may have been testing it mostly with ldm 2.0.6 ... not the more recent versions ... i should remember to test that.
14:45
<warren>
it clearly isn't fixed with 5.1 here
