cyberorg, doesnt opensuse have hibernate ?
03:16
<cyberorg>
ogra, yes it does
03:16
<ogra>
so if someone wants to use a hibernated laptop to test a thn client env you would wipe his hibernated session
03:17
(using mkswap from initramfs)
03:18
not a good idea imho
03:18
<cyberorg>
ogra, i was replying to <warren> RUN_MKSWAP=true <warren> why would you want it to not run mkswap?
03:18
<ogra>
aha
03:19Q-FUNK has joined #ltsp
03:19
<cyberorg>
nothing about the idea, but someone may prefer not tu run mkswap from nbdswapd and let initrd do it
03:19
<ogra>
oh, he was eferring to nbdswapd, i see
03:20
well, for the above reasons :)
03:20
<cyberorg>
:)
03:20
<ogra>
mkswap in nbdswapd actually only runs mkswap on a temporary swapfile on the server
03:21
its pretty dedicated to only this :)
03:22
(and ubuntu uses nbdswapd extensively btw, we have a mechanism that automatically requests nbd swap if your client has less than 48M to make sure they boot properly)
03:22
<cyberorg>
ogra, yes, we can have mkswap run on nbd mounted swap device from initrd it desired too, i've added your code to our initrd that does the same :)
03:23
detects less ram and activates swap, unfortunately it doesn't seem to work, it creates the swap file on the server, but somehow fails to mount on the client
03:23
i'll get back to it later
03:24
<ogra>
there was a debian bug with long discussion from the debian-edu folks about that issue, which is why we added the option first place
03:24
(to not blindly wipe swapspace)
03:24
vagrrant would know the bugnumber i guess
03:25
<cyberorg>
ogra, i am using the same nbdswapd from upstream
03:26
xinetd must be culprit here
03:26
<ogra>
likely
03:26
even though, can you see the nbd device ?
03:26
i could also imagine that you have an nbd version that simply doesnt support everything yet
03:28
<stgraber>
ogra: Do you happen to know what sysadmin to ping for problems with servers over the weekend ? the QA team server has its HDD completely full so none of our websites work ...
03:29
<ogra>
stgraber, wasnt there a #canonical-sysadmin channel on freenode ?
03:29
ah, yes there is
03:29
<stgraber>
yes, but you never have someone responding during the weekend
03:29
<ogra>
i'd try there
03:30
<cyberorg>
yes nbd device is there
03:30
i am not in a hurry to fix that one yet :)
03:31
nbd-2.9.9
03:33
<ogra>
2.9.9 should be fine
03:39
stgraber, i pinged on an internal channel, lets see if there is more reaction
03:40
<stgraber>
ogra: thanks

asac: seems we're finally in Debian/unstable. I just added my bit for the SRU to LP #214119. now, we'd need this to be sync'ed to hardy-proposed.
07:53
asac: of course, since I directly upload all fixes to Debian, silly me forgot to quote the relevant LP bug.

<x1250>
I'm reading the 4.2 documentation, but ubuntu doesn't have an inittab file, is there any docs related to this issue?
08:00
hardy has 5.0
08:04gvy has quit IRC
08:05
<x1250>
the /opt/ltsp/i386/etc/inittab file is a link to /tmp/inittab, but its broken
08:05viking-ice_ has joined #ltsp
08:06
<x1250>
and /etc/inittab doesn't exist
08:08
<Q-FUNK>
what are you trying to do with that file?
08:08
nowadays, most configuration is done in lst.conf
08:08
including to enable consoles

Q-FUNK: I really don't know yet (chapter 1, 4.2 documentation, tho using 5.0 on ubuntu)
08:09
is there any 5.0 documentation as complete as 4.2?
08:12
<Q-FUNK>
there should be
08:12
5.0 has been in use since... was it Gutsy?
08:12
or was it Feisty, even?

I don't know, but this page http://wiki.ltsp.org/twiki/bin/view/Ltsp/Documentation shows almost no docs for 5.0, and the ubuntu wiki page is not as complete/verbose as the 4.2 manual

x1250: there are some wiki pages, LTSP settings are exactly the same, only the way to install it defers
12:39
<x1250>
stgraber: I have two pc's in here, one with the "LTSP installation" from alternate cd in ubuntu, and this one, which seems to have the same ltsp packages as the other pc. Oddly, in this pc I have nothing on /opt and the other one have /opt/ltsp. I wonder what I'm missing. Any clue?

<stgraber>
you probably have ran : ltsp-build-client on one and not on the other
12:50
<x1250>
yep, I did and that was it, thanks
12:57
stgraber: sorry for bothering, is ltspfs package really needed? I ask because I really want to try a very basic installation. Is just ltsp-server enough for this?
12:58
<stgraber>
ltspfs is needed if you want your USB keys, cdrom and other devices to work with LTSP
12:58
<x1250>
stgraber: thanks
13:13Nuba1 has left #ltsp
13:20
<x1250>
is /opt/ltsp/i386/etc/apt/sources.list the sources.list used to install software inside ltsp? if so, software installed using /etc/apt/sources.list would not be "seen" by ltsp unless installed through chroot using /opt/.../sources.list, isn't this true?

are these packages really needed for a working ltsp? dhcp3-server, nfs-kernel-server
14:34
<johnny>
no
14:34
<x1250>
ok, thanks
14:34
<johnny>
unless you don't have a dhcp server
14:35
<x1250>
Uhm, I don't have one
14:35
<johnny>
then you do need it
14:35
stop being so minimal.. make it work first..
14:35
<x1250>
and nfs-kernel-server?
14:35
:)
14:36
<laga>
on ubuntu, it's probably not needed.
14:36
<johnny>
you only install stuff in the chroot for locally run apps
14:36
which is not most apps usually
14:37
<x1250>
laga: yo mean nfs-kernel-server?
14:37
yo/you
14:37
<johnny>
yes
14:37
<laga>
yes.
14:37
<x1250>
ok, I'll purge it then
14:37
<laga>
btw, you get to keep both pieces if it breaks :)
14:37
<johnny>
yeah
14:37
just make it work.. then worry about removing stuff

x1250: Are you limited by system resources? Rather than trying to strip stuff out... I just got done installing Kubuntu 8.04 on a P3-733Mhz 384MB Ram 13GB HDD server and hooked a P2-233Mhz 64MB client to it. I've also loaded up Dansguardian (it's for the neighbors kids) - didn't want Edubuntu... If you've got the HDD space and are just worried about speed, start with Xubuntu and do the full LTSP install. (Ubuntu runs slower than K
15:24
By the way... I'd previously had 5.10 Kubuntu LTSP running on a P2-450Mhz 512MB ram for a couple of years (no not for games!) before migrating machines when I went to 6.10 Kubuntu (P4-2Ghz). This same P4-2Ghz is now running just Xubuntu 7.10 (no LTSP right now).
15:30
<x1250>
LTS1: nope, I'm not limited on system resources. I just wanted the most basic setup so to learn how things work and how to extend funcionality if I want to do so. Its just I prefer it to be that way.
15:30
<johnny>
then you'll prolly break stuff :)
15:32
<x1250>
I found what I needed on QuickInstall file in ../doc/ltsp-server. I think it will work, but I see /etc/dhcpd.conf uses
15:32
option domain-name "example.com";
15:32
and I don't know yet if that would be correct for my setup
15:33
I'm using ubuntu.example.org as hostname
15:38jammcq has joined #ltsp
15:40
<johnny>
ubuntu uses a file in /etc/ltsp
15:40
by default
15:40
for dhcp config
15:43
<x1250>
yes. but it uses option domain-name "example.com"; too, and I don't know yet whats the purpose of that option
15:48
<johnny>
you're supposed to change it
15:48
to whateger you wanna use
15:48
for your internal lan
15:49
i usually use .lan domains
15:49
some people use .local
15:51
<x1250>
ok, I'll try tHAT
15:51
tHat/that :P
15:53
<vagrantc>
in most cases, the domain name for the thin-clients is almost irrelevent.
15:54
<johnny>
having fqdn is just something i do
15:54
always

Uhm, I have a problem, the thin client getting my ISP's DHCP ip, so its not seeing my dhcp server. Is this a "newbie gotcha" of some type? :(
16:08
getting/is getting
16:09
<laga>
are your thin clients connected to the same network as your WAN interface? scary
16:11
<x1250>
laga: yes
16:11
<vagrantc>
x1250: you probably have two DHCP servers running on the same network, most likely your router, and the LTSP server
16:11
<johnny>
x1250, thus me asking if you were running a dhcp server earlier :)
16:11
<vagrantc>
x1250: easiest way around that is to put two NICs in your server, and have a separate network for thin clients
16:12
<x1250>
ok, I have another router lying around, I'll try that
16:18* vagrantc wonders how that will help
16:18
<vagrantc>
x1250: you're using a router instead of a switch or hub?

add some users :)

no

ok, thanks
16:58
I'm using SOUND=True, and also VOLUME=95, but sound is very low on the client. Is there anything I can do to improve it?
16:59
this is my config_ http://paste.ubuntu.com/11324/
17:00
is there a need to restart any service after modifying lts.conf? I read that if using /var/lib/tf.../lts.conf, then no, but after setting VOLUME to 95 I saw no changes, that's why I ask

johnny: is there anyway to "hide" some given system functionality from the thin client? I was thinking I would not like thin clients to be able to change their passwords, for a little example.
18:46
or hide the gnome system menu, for another
