hey ...good morning ...
05:16
X_MODE = 1024x768 isnt working for me... is this the right parameter ?

<ogra>
try X_MODE_0
05:17
<cdealer>
ok
05:17
thanks
05:19

so are there any new features in ltsp 5 in hardy?
05:22
or is it just cleanup?
05:22* johnny tries to remember..
05:23
<ogra>
well, depends how you define *new* :)
05:23
autologin and sshkey based logins work in hardy :)
05:24
beyond that its only stabilization
05:25
most of the annoyances are gone bot i wont include and new not mature features ina realease that has three years of support
05:25
s/and/any/
05:33
<johnny>
ssh key. hmm..
05:33
it'd be nice to have autologin with ssh key
05:33
<ogra>
its in hardy
05:34
<johnny>
so.. is there a working list of features added to ltsp5 overall? since the time of gutsy release?
05:35
<cdealer>
ogra, X_MODE_0 didnt work .. Im seting inside /var/lib/tftpboot/..../lts.conf

05:59tornio has joined #ltsp

<tornio>
I am having a problem with pxe and tftp. The problem is that the client doesn't find the kernel. pxelinux.0 is found and the bootloader starts but then it complains about the missing kernel. Where should I start looking for the problem?
06:00
The configuration files should be ok, I haven't been able to find anything wrong with them.

morning

<Gadi>
etyack: !!
09:26
<etyack>
Gadi: the work on the amd geode chipsets, is that for hardy?
09:27
<Gadi>
no - gutsy, too
09:27
well, I should say
09:27
<etyack>
are the packages in launchpad?
09:27
<Gadi>
should work on gutsy - who knows what ubuntu will include/package
09:27
in fact, it is dev'd with gutsy in mind
09:27* Gadi thinks
09:28* Gadi thinks they are on LP
09:28
<Gadi>
but, it is in active dev, so im not sure what versions are there
09:28
you need 2 debs: xserver-xorg-core and xserver-xorg-video-amd
09:29
<etyack>
are they hosted somewhere where I can access them? we have an amd geode client I want to test.
09:29
<Gadi>
should be - lemme check the LP bug report
09:31
hmm...
09:31
try the ones from here: https://launchpad.net/~q-funk/+archive
09:31
you should only need xserver-xorg-core and not the whole set
09:31
and -amd, as well, of course
09:32
<etyack>
thanks. i don't have the client with me today, but plan to test it later this week.
09:33
<Gadi>
etyack: do you know what BIOS it has?
09:33
the amd-based systems are very BIOS-dependent
09:34
hopefully, we fixed them all with our patch
09:34ogra_ is now known as ogra
09:36
<etyack>
Gadi: no i don't. actually, a few of the ubuntu developers, Ogra I believe has one, have the AMD workstation and so does Warren.
09:36
<Gadi>
ah - thincan?
09:36
<warren>
I wouldn't call it a workstation
09:36
<ogra>
lol
09:36
<etyack>
ok, thin client?
09:36
<ogra>
skinny client :)
09:36
<Gadi>
workstation not workhorse :)
09:37
<etyack>
advanced paper weight
09:37
no, not a thin can -- TermTek Tk 3550 I believe
09:40
<Gadi>
ah
09:41* Gadi often wonders where they fit all this junk in Taiwan :)
09:41
<Gadi>
its not THAT big a country
09:41
<ogra>
they dont need to
09:41
they export it immediately
09:41
there is a constant stream of silicon going in ... and a constant stream of HW going out
09:42
<Gadi>
ah, rivers of silicon.... its like a perverse dream....
09:42
<ogra>
heh
09:43
<Gadi>
ok, so this whole greeter communications channel in ldm is very frustrating
09:44
grrr
09:44
!seen sbalneav
09:44
<ltspbot>
Gadi: sbalneav was last seen in #ltsp 1 week, 6 days, 0 hours, 45 minutes, and 19 seconds ago: <sbalneav> What are we looking at?
09:44
<Gadi>
dios mio
09:45
<warren>
Gadi, frustrating in what way?
09:45
Gadi, (I mean, I agree, but wondering what issue you are having)
09:45
<Gadi>
All I want to do is display a message in the message field on spawn - I do a set_message, the message sets fine, but then the Username entry field becomes inactive
09:45
oh!
09:45
wait
09:45
I know why
09:46
I think
09:46
bbiab
10:04
they should make extra processors that you can just slip into the PCMCIA card of ur laptop....
10:05
I'd buy that for a dollar

Only root can do that.
12:17
error: LTSP client installation ended abnormally
12:19
after I install my chroot, after-install) runs that
12:19
and it somehow thinks it is not root
12:20
<milesd>
warren, I usually only see "only root can do that" in reference to mounting/unmounting. I'm not saying it couldn't come from somewhere else, but you might want to check to see what is/isn't mounted
12:20
warren, if it were a simple file permission problem I would have expected "permission denied"
12:23
<Gadi>
warren: I think after-install) happens *in* the chroot
12:23
in which case, your user may be undefined
12:23
<ogra_cmpc>
indeed it does
12:23
but it only defines a mileston point during building
12:24
<Gadi>
try: USER=root rm -rf /var/lib/rpm/__db*
12:24
<warren>
Gadi, you sure?
12:24
<ogra_cmpc>
thats would be odd
12:24
<warren>
mm
12:24
<Gadi>
indeed it looks odd
12:25
<warren>
is there a way to have it display what it is running without editing it and adding set +x?
12:25
<ogra_cmpc>
probably someything selinux related ?
12:25
<warren>
or maybe adding a ltsp-build-client --verbose would be good
12:25
<ogra_cmpc>
i've never seen such a behavior on debian or ubuntu
12:25
<warren>
ogra_cmpc, nothing in the audit logs
12:25
<ogra_cmpc>
we have --debug
12:26
<warren>
what does --debug do?
12:26
<ogra_cmpc>
but thats likely not really helpful in your cae
12:26
show details about the plugins
12:26
<warren>
oh
12:26
<ogra_cmpc>
but its only telling you what it loads when
12:26
<warren>
ok, so after-install runs IN the chroot?
12:27
<ogra_cmpc>
well, it defines a waypoint
12:27
nothing more
12:27
<warren>
how does it do that? each line is called in the chroot individually or it is put into a script within there?
12:27
<ogra_cmpc>
its after the basic system was bootstrapped *and* after all additional (late-packages) are installed
12:27
err
12:28
eraly-package, not late-packages,m sorry
12:28
*early
12:28
run it with debug, you will see how it does what
12:29
but nothing here should influence your rm command
12:29
did you check the file permissions ?
12:30
<warren>
what does early-package mean?
12:30
we don't have any concept of that. all packages are installed in one transaction.
12:30
<ogra_cmpc>
well, we have three steps
12:31
the basic bootstrapping ... that gains tou the bare minimal system
12:31* warren running
12:31
<ogra_cmpc>
then early-packages ... that installs ltsp-client and friends
12:31
then late-packages ... thats the kernel etc
12:32
you can preseed EARLY_PACKAGES and LATE_PACKAGES in the config to install edifferent stuff there
12:33
i.e. the mythbuntu guys just created a mythbuntu thin client in ubuntu by just changing the late packages list
12:33
<warren>
cool
12:33
<ogra_cmpc>
yeah
12:33
<warren>
I may or may not use early or late packages.
12:33
I don't need it for now.
12:34
<ogra_cmpc>
nobody forces you :)
12:34
i bet you have other mechanisms to adjust the package list

"We're in the year 2008 AD. The whole company has happily switched to LTSP ... The whole? No! One little department inhabited by indomitable accountants still resists ..." -- Hello all, there's this one Windows app that they still need to run. And it's a big one, so I can forget about wine or qemu.
14:14
Is it possible to let them have two X servers running on their client? One for LTSP, of course, and a second one on another VT connects, god knows how, to a kind of remote windows machine?
14:14
I've never tried this before, and it was much easier if I knew what I'm actually looking for. Can anyone give a hint?
14:14
<vagrantc>
you could probably use rdesktop to connect to windows terminal services
14:15* vlt googles rdesktop
14:19
<cliebow_>
rdesktop rocks!
14:24
<vlt>
What I've read so far sounds really god (despite that it's used to enable access to Windows). This might be the wrong channel, but can I use it to connect to a standard W2k prof. or do I need an extra TS app there?
14:24
<johnny>
you need to have terminal server licenses
14:25
i'm imagining
14:25
and the software
14:25
XP is the first windows that comes with 1 remote desktop client access
14:26
<cliebow_>
i believe there is a server for 1 or two users in xp pro
14:26
<vlt>
johnny: "and the software"?
14:26
<johnny>
terminal services?
14:26
<cliebow_>
you need to sacrifice first and second born..
14:26
<johnny>
i think
14:26
it isn't free
14:26
<cliebow_>
heh
14:26
<johnny>
and isn't even supported for much longer
14:27
<vlt>
Thank you. I think I'll do some further reading ...
14:28
<ogra_cmpc_>
vlt, your software needs multiuser licenses if you dont want to use it illegal
14:28
<johnny>
yes.. that too..
14:31
<vlt>
The software is licensed properly for the whole department. My goal is to switch them over to LTSP too, and get the big noisy Windows machines out there ;)
14:31
<johnny>
careful the BSA doesn't show up
14:31
and steal all your machines :)
14:31
<ogra_cmpc_>
well, if your server is beefy enough you could set up a bunch of virtual machines
14:32
<vlt>
ogra_cmpc_: Thought of that too.
14:32
johnny: BSA?
14:32
<ogra_cmpc_>
kvm is oretty good in that i heard
14:33
*pretty
14:33
its supported by default in newer ubuntu
14:34
<cliebow_>
BSA=Gates' Gestapo

14:36
<ogra_cmpc_>
heh
14:40* ogra_cmpc_ tires to remember the runes for VAR=$(command) in makefiles
14:40
<Gadi>
ah, the runes...
14:41
<ogra_cmpc_>
i thought $$(command) would suffice, but seems not :/
14:42
<Gadi>
btw: ldm-script in ldm-trunk does not get produced properly if --libexecdir is not defined in configure
14:42
not sure if that affects anyone
14:42
but, I learned the hard way
14:42
:)
14:42
<ogra_cmpc_>
we all know
14:42
<Gadi>
ok
14:42
<ogra_cmpc_>
just ask next time :P
14:43
<Gadi>
well, its hard to ask questions that you dont know are questions
14:43
:)
14:43
you know, you could set a better default
14:43
<ogra_cmpc_>
well, you could just have used the latest hardy package ;)
14:43
<Gadi>
that ${exec_prefix}
14:43
*than
14:44
<ogra_cmpc_>
well, i'm currently fighting in ubuntu to get the autotools fixed to set a sane default for libexecdir
14:44* Gadi is happy he never has to say things like that
14:44
<ogra_cmpc_>
its just silly to reference a dir that doesnt and will never exist on the host system
14:48
<warren>
ah...

yeah
14:52ogra_cmpc_ is now known as ogra_cmpc

14:55

by default it locks it
14:55
<ogra_cmpc>
snap
14:55
<Gadi>
ogra_cmpc: no, by default it still locks root's passwd

14:56
<vagrantc>
ogra_cmpc: any idea on the changes in mksquashfs ?
14:56
<warren>
changes to mksquashfs?
14:56
<ogra_cmpc>
vagrantc, well, only the --nolzma thing
14:56
<vagrantc>
ogra_cmpc: sounds like in debian sid and/or lenny it's borked
14:56
<ogra_cmpc>
but that was reverted again
14:57
well, -nolzma should actually help (note its only one dash)
14:57
warren, upstream added lzma support and indeed defaulted to it ... no kernel supports lzma unpacking yet
14:58* vagrantc is quite happy with NFS as the default
14:58
<warren>
ogra_cmpc, if that's the case, then we definitely didn't do it in Fedora
14:58* ogra_cmpc didnt have any probs with suqashfs yet
14:59
<ogra_cmpc>
warren, we changed the default in ubuntu as well... debian might not yet
15:00
<vlt>
Should the day finally come that I get those Windows machines (or the one, or machines in kvm ...) accepting rdesktop connections ... is it better to use an extra X on the (thin) client or can the rdesktop window be integrated into the remote LTSP desktop? (I know that running vncviewer on a remote LTSP desktop doesn't perform that good ...)
15:01cliebow_ has quit IRC
15:02
<vlt>
Reminds me of one thing I always wanted to know: Can I spread apps on several LTSP servers, e. g. running OO.org on a an extra machine?
15:02
<Gadi>
vlt: you can do either or - if its only for one app, make a launcher on the desktop
15:03
vlt: you can do anything and everything
15:03
<vlt>
;)
15:03
<Gadi>
:)
15:03
it's all plumbing
15:04
oh, and personally, I would say get yourself a windows terminal server
15:04
dont bother trying to do VMs
15:05
<warren>
Gadi, would that launcher use rsh or something?
15:06
<vlt>
Gadi: Yes, sounds like too much effort ...
15:06
<warren>
(how does it authenticate with the same user?)
15:06
<Gadi>
for rdp? no -rdesktop
15:06
<ogra_cmpc>
warren, ssh with key auth :)
15:06
<warren>
ooh.
15:06
<ogra_cmpc>
ssh -X actually
15:06
<Gadi>
for an X application, ssh
15:06
for a Windows RDP, rdesktop
15:07
for Citrix ICA, ICA client
15:07
....
15:07
<ogra_cmpc>
or -XC ... since we run on the server ... that should be able to handle compression :)

handling single-sign-on depends on the client
15:07
or ssh DISPLAY=<thinclientdisplay>
15:07
unless you have consolekit
15:08
:P
15:08
<ogra_cmpc>
well, ssh -X from your session doesnt
15:08
that only cares for your key on the server
15:08
<Gadi>
no, i mean to launch an app from another server
15:08
<ogra_cmpc>
yes me too
15:09
<Gadi>
and set the display to the thin client display directly
15:09
rather than use a proxy
15:09
<ogra_cmpc>
ssh -X me@otherserver firefox
15:09
ah, thats what you men
15:09
<Gadi>
right - that uses a proxy
15:09
<vlt>
Gadi: Yeah, what my first question meant is: Is there a sigificant performance loss when using "remote in remote" window (as it is with vnc) or can the rdp data "passed through"?
15:09
<Gadi>
I mean: ssh me@otherserver DISPLAY=<thinclient> firefox
15:09
<ogra_cmpc>
well, without proxy is a hell lot more complicated
15:10
no, you need to get xauth right first
15:10
just setting DISPLAY wont work
15:10
<Gadi>
fine. xhost+otherserver; ssh me@otherserver DISPLAY=<thinclient> firefox
15:11
but, mine will play videos :P
15:11
vlt: no - vnc sucks
15:12
<vlt>
FACK
15:12
<Gadi>
the only issues with rdp from the server are sound
15:13
bec sound needs to be wrapped in padsp

and that makes it degrade

I guess the accountant department will get over it

rawrg - that's what I'm dealing with right now, rdp thin-client-to-win2k server (VMWare). Can't get sound going. Not sure how to wrap it in padsp..
17:44
Is it pretty safe to, if you are moving from AMD64 to i386 server (not chroot), to just copy the whole /opt/ltsp dir and copy it back over once you've rebuilt the server (and install correct ltsp packages)? (Ubuntu Gutsy)
17:44
To basically keep the modifications you've made

<RyanRyan52>
how do I do the eqivalent of "svn di -r 1:2" (looks at the differences between 2 revisions...) with bzr?
20:32
<dberkholz>
RyanRyan52: try bzr diff --help
20:33
<RyanRyan52>
ohh...I didn't think of that. Thanks...
