ogra: looks like I might skip UDS, after all. are you gonna be at LinuxTag?
06:28
<ogra>
yes, i'm runing the ubuntu grill
06:28
(last Q&A session last day)
06:28
Q-FUNK, and indeed i'll be at the ubuntu BBQ later that evening
06:33
<Q-FUNK>
excellent :)
06:34
ogra: I'm gonna be there for the Coreboot sessions, myself. they're doing a live porting to DBE61
06:34
<ogra>
nice
06:34
i'll attend that if my schedule permits
06:34
<Q-FUNK>
the port already exists for v2, but now they're wrapping up v3.
06:35
ogra: can you bring your thincans with you? I'd update the firmware on both.
06:36
<ogra>
if you have a power supply with you ... my bad is already quite full so i'd like to save weight

<sergiu26_buc>
i need to install centos using PXE
07:14
the server is running FreeBSD
07:14
<davidj>
sergiu26_buc: Hello
07:14
<sergiu26_buc>
:P
07:15
<davidj>
Look at ltsp.org first ;-)
07:15
<sergiu26_buc>
well....no FreeBSD support as i see
07:15
:((
07:16
just major linux distros
07:18
<ogra>
Blinny, sorry, no, i'll take a deeper look after UDS, currently i'm so swamped in other stuff that i dont get much to ltsp
07:18
<davidj>
sergiu26_buc: The technologies used are standard unix tools.
07:19
<Blinny>
Ok right on.
07:19
<ogra>
sergiu26_buc, the principle is the same across the board
07:19
<davidj>
sergiu26_buc: tftp, nfs, bootp or dhcpd

ogra: Do you know if freebsd has nbd?
07:20
<ogra>
davidj, he wants t install centos using etboot i doubt he needs nbd :)
07:20
*netboot
07:20
<davidj>
a fair point ;-)
07:20
<ogra>
no idea if they have it in their kernel though
07:22
<sergiu26_buc>
well....the server is FreeBSD...i made a clean os using the actual server OS for the PXE box...and it's working
07:23
but how do i install a different operating system
07:27
<davidj>
sergiu26_buc: Option 1:
07:28
put a hard drive in the diskless system, install centos, move the hard drive to the server and tell it to export it read-write to the diskless system.
07:29
<sergiu26_buc>
aha
07:29
OR? :D
07:29
<davidj>
You will need to hack around a bit to build an initrd and pxe image; the ltsp 4 wiki can probably help with that.
07:29
OR:
07:29
OR depends on the purpose of the machine.
07:30
<ogra>
doesnt centos have a netboot install image ?
07:30
<sergiu26_buc>
what about a boot loader ? what if i want to install diferent distros on the FreeBSD server...all for the same diskless machine
07:30
<ogra>
like debian or ubuntu do ?
07:30
<davidj>
sergiu26_buc: pxe is your boot loader.
07:30
<sergiu26_buc>
well...i could get a menu right?
07:30
u know, to select what i want to boot
07:31
<davidj>
pxe does permit a menu.
07:31
<sergiu26_buc>
excelent
07:31
anyways i need a hdd in it
07:31
thanks for your time
07:31
<davidj>
sergiu26_buc: Does freebsd support ext3 ?
07:31
If not, you will need to tinker a bit.
07:32
<sergiu26_buc>
yup
07:32
will see...step by step :D
07:32
i was under the impression that i could install whatever OS i want to...eve windows or solaris
07:32
<davidj>
You will need to pass some parameters to the kernel at boot time to tell it where to find the root filesystem, look in the ltsp wiki.
07:33
<sergiu26_buc>
that is done by dhcpd.conf
07:33
<davidj>
I don't think windows supports remote root filesystems.
07:33
Yes, kernel parameters are in dhcpd.conf or in pxe config
07:33
<sergiu26_buc>
well...it might not know that is remote
07:33slidesinger has joined #ltsp
07:33
<sergiu26_buc>
i use pxe with dhcpd instead of etherboot with bootpd
07:34
ok then, thanks for u're time
07:34
<davidj>
I use pxe iwth dhcpd. Here's the entry in pxelinux.conf I use to install Centos 5;
07:35
label c5
07:35
kernel c51/vmlinuz
07:35
append initrd=c51/initrd lang=en_US.UTF-8 keymap=us vnc vncconnect=192.168.0.251 ip=dhcp method=nfs:192.168.0.251:/opt/centos5 rescue
07:35
07:35
That's it.
07:35
The initrd in this case is in the images directory of the first Centos CD
07:36
<sergiu26_buc>
i figured
07:36
ok then...i'll get to work
07:36
<davidj>
This line would not work for a regular Centos setup, it's for remote installs.
07:36
Have fun!
07:36
<sergiu26_buc>
thanks :)

<mhterres>
hi ogra
08:16
<ogra>
mhterres, hey
08:17
<mhterres>
ogra, are you the responsible for ltsp ubuntu packages, am I right ?
08:17
<ogra>
right
08:18
<mhterres>
great
08:18
so maybe you can indicate me someone that can help me with ltsp and kiosk mode
08:18
:-)
08:19
using the ltsp-build-client --kiosk command
08:19
<ogra>
whats your prob with it ?
08:20
<mhterres>
I run the command and now I don't know how to configure the kiosk mode, and I didn't find any documentation about this
08:20
my goal is to start the client and it boots and start firefox
08:20
and if I close firefox I need to logout :-)
08:20
<ogra>
thats what kiosk does atm
08:21
you need ip forwarding enabled on the server and i'd suggest to take a look at http://doc.ubuntu.com/ubuntu/serverguide/C/firewall.html
08:21
beyond that it should just work out of the box
08:23
for configuring i.e. a different startpage i fear you need to manually modify a firefox config on the server, copy it to the client chroot into /home/kiosk and re-roll the image, i'll look into a better methid for intrepid (kiosk is a somewhat unloved stepchild)
08:23
<mhterres>
but how can I set firefox to start ?
08:23
this is my main doubt :-)
08:23
<ogra>
the --kiosk mode does that automatically
08:24
it sets up a kiosk user in the chroot with ~/.xsession
08:24
<mhterres>
so the --kiosk option is set firefox as the default app ?
08:24
<ogra>
right
08:24
<mhterres>
oh great :-)
08:24
I'll take a look
08:24
thx
08:24
<ogra>
it creates the user in the chroot, sets gdm up for autologin and puts ~/.xsession in place for a fullscreen firefox session

ogra, the strange part is: If I put the TC to boot in the kiosk mode, it logs in X and does nothing
08:36
I'll look better know that I understand how it works

italc does very weird things on my system, sometimes it shows the clients, other times it doesn't... and I can only connect via localhost:port number, is that normal?
08:43
I have all my clients defined by ip and mac address, but that seems irrelevant in italc, as it tells me the users are not connected when trying to connect directly via ip and mac address
08:44
<stgraber>
you can't connect directly as ica (the client part of italc) is running on the server, not on the clients
08:45
for LTSP, it's always localhost:10000+<last byte of ip>
08:47
<spo0ner>
has anyone had any experience with seamless rdp?
08:49
in particular, I'm just trying to verify that the NoDesktop DWORD registry key being set to a value of 1 won't jack anything up on a Win2K3 server
08:50
I know this room is primarily for ltsp but I can't find any other resource to see if anyone else has done this

08:57artista-frustrad has quit IRC
08:57
<Nubae>
I still get no user logged in
08:57
like it finds the client, but then not the username
08:58* ogra had to use the external IP of the server instead of localhost
08:58artista_frustrad has joined #ltsp
08:58
<stgraber>
ogra: oh, that's weird ... anyway, demo mode and tcp stuff have been rewritten in 1.0.8 so that kind of stuff should be fixed
08:59
<ogra>
well, it worked fine then, just not with localhost or 127.0.0.1
08:59
<Nubae>
hmm, its very strange on my system, some users come up, others dont, seems completely random
09:00
<ogra>
all using gnome ?
09:00
<Nubae>
yep
09:02
when I try to add a computer and do localhost:10000+lastbyteofip or 192.168.0.254 or 127.0.0.1, it seems to find the client, but not the user connected to it
09:03
<ogra>
192.168.0.254 is likely not the external ip
09:03
<stgraber>
Nubae: that may mean that ica (client part) has crashed
09:03
<ogra>
sounds like the default for the TC network
09:04
<stgraber>
Nubae: try closing the session and reopen
09:08
<Nubae>
ogra: it isnt, external ip is 192.168.1.42, should I be using that?
09:09
<ogra>
Nubae, try that ...
09:09
<Nubae>
nah, still get no user logged in
09:09
<ogra>
i.e. for a client with IP 192.168.0.250 use: 192.168.1.42:10250
09:10
<Nubae>
ah wait... I'm doing 10000250
09:10

vagrantc, hey

i talked to mdz about the -ac :)

he admitted it was from his very first ldm variant :) and asked that we please switch off tcp access generally (at least in the default)
10:06
<vagrantc>
heh
10:08

(adding "-nolisten tcp" )
10:09* ogra sighs about openssl
10:09
<ogra>
yay, half the world regenerates keys
10:09
<vagrantc>
yeah.
10:09
eeyk.
10:10
i think one of my keys actually pre-dates the vulnerability, though.
10:10
<ogra>
most of mine do luckily
10:10
only the recent ones dont ...
10:18

is there anyone who have a problem with a saned into a ltsp5 ? i haven't any error, juste saned isn't running

i'm guessing many server-side keys will need to be regenerated....
10:25

vagrantc, ergh, strikes me ... *lots* of ltsp installs need to regenerate
10:25
should we send a note pointing to the debian and ubuntu security announces to ltsp-devel ?
10:25
<Blinny>
openssl security vulnerability?
10:26
Ah I see.

I wouldn't mind seeing one in ltsp-discuss

oh, my ssh key seems to have been generated before Feisty !!! I didn't think it was that old :)
10:32* ogra generated his ssh key on debian woody if he remembers right
10:34

stgraber: before 2006 ?
10:34
<stgraber>
2005 it seems
10:34
<Blinny>
ltsp-update-sshkeys just reads the host keys from /etc/ssh right?
10:35
<stgraber>
looks like all broken SSH keys were removed from Launchpad
10:35
<Blinny>
'least.. that's what I'm reading in it
10:37

uggh..it sucks i have to rebuild my image..
10:37
so.. is the patched version in hardy already?

johnny: it's been uploaded to hardy-security a few hours ago so I'd assume so
10:42
<Blinny>
Yes, it's available.
10:43viking-ice_ has quit IRC
10:44
<stgraber>
ok, so update, it should force host keys to be regenerated (at least that's what the changelog says)
10:45
<Blinny>
I didn't see that happen/mentioned in the safe-ugprade so I did it manually.

What can I do to try and troubleshoot random freezes on thin-clients with Ubuntu Gutsy LTSP? is xsession-errors the best bet, or .. ? It seems they (Neoware e100s) hard-lock continuously during normal usage, no matter what. This is a lab of 35 systems...

lns: You can try having the clients send the syslog to the server, that can help.
20:48
lns: Another thing to check is just how hard they freeze. Is it just the X session, or is it locked up hard?
20:49
lns: Can you reproduce it consistently?
20:49
lns: Can you reproduce it without X?

21:00
though I'm not the first hit anymore
21:00
<monteslu>

21:00

21:01

21:01
<monteslu>

21:01

21:01

21:02
<rjune_>

21:02
<davidj>
¿Gosa gosa?
21:02
<rjune_>
Why isn't it in fedora?
21:02
<davidj>
(bad pun, I must be tired. )
21:02
<rjune_>

21:02
I've not actually looked for them mind you, but they weren't in there when I was workign with fedora
21:03
<monteslu>
gosa looks like yast

<monteslu>
ok, giving my first 64bit home install a shot...
21:04
<rjune_>
similar to yast.
21:05
a lot of overlap.
21:05
difference being is there's effort to make it work on all distros, not just suse
21:08
<davidj>
interesting.
21:08
<rjune_>
yeah
