<bennabiy>
you ever tried to do a 7.1 install on older server hardware? I have an IBM eServer 235 which the network is not working properly.
00:00
I think I am just going to add a nic to it, and see if that fixes it.
00:11
<vagrantc>
pretty much exclusively do server installs via network boot
00:11
so the first issue to resolve is networking ... usually only a matter of loading the firmware from usb

<bennabiy>
that was it :) and I accidentally plugged into the RS-485 port ;)
00:28
I was reaching behind the machine in a tight corner
00:29
you ever deal with xen?
00:33
<vagrantc>
in the process of getting rid of the last of our xen servers today, actually :)

00:41
actually, tomorrow is the next one...
00:44
<bennabiy>
vagrantc: Did you see what I had posted earlier about the sound issue, and how it was fixed by restarting the pulseserver on the client (temporary fix, but without the -L fix involved)
00:44
<sunweaver>
oops: vagrantc has quit...
00:44
<bennabiy>
bah.. I just noticed that as well
00:44
Hello sunweaver!
00:44* sunweaver is the guy from X2Go upstream...
00:44
<sunweaver>
hi!
00:44
bedtime here at DebConf13-Switzerland...
00:44
<bennabiy>
Someone was looking for you earlier, but cant recall who now
00:44
How is it going?
00:44
<sunweaver>
tired! Local time is 2:44 and I have been working on packaging MATE the whole night.
00:45
<bennabiy>
YAY!
00:45
I love MATE (both the DE and the drink)
00:45
<sunweaver>
hehehe...
00:45
<bennabiy>
I am drinking my gourd now
00:45
<sunweaver>
MATE works really smooth in X2Go and so it also probably does in LTSP.

yes, it is very smooth in ltsp
00:45

quick question for everyone... If I want the lightest weight DE in debian, would it be KDE, LXDE or Xfce? (I know it isn't gnome3)

probably lxde. last time I used xfce it wasn't much lighter than gnome2, and while kde is good at trimming itself down in low ram situations, it's still not that light
13:18
it's been a long time since I tried lxde though

hey vagrantc
15:23
how long does dpkg-scanpackages take to run on a full deb 7.1 repo?
15:26
<vagrantc>
no idea
15:26
but why?
15:26
i mean, what are you trying to do?
15:32
bennabiy: there are many tools to generate apt repositories, i would not reccommend doing it manually
15:34
<bennabiy>
I am about to do an assortment of various deb installs, and I pulled all the .deb files to make a local repository. I am generating the Packages.gz file
15:35
That way I can do each install over the local network, rather than pulling from the inet each time
15:35
I was looking for you earlier to see if that was the best way to do it, but you werent here. ;)
15:35
<vagrantc>
i'd reccommend using reprepro
15:36
<bennabiy>
Can that be run on mint 15?
15:36
<vagrantc>
alternately, approx or maybe apt-cacher-ng
15:36
bennabiy: how would i know? :p
15:37
<bennabiy>
That is my issue... All my machines in the office are mint or kubuntu based .. and I am about to set up about 4 or 5 deb servers
15:37
I feel bad about communicating about non-ltsp specific things in here, is there a better way to reach you?
15:37
<vagrantc>
i would e surprised if any of those wasn't available for mint
15:38
or ubuntu
15:38
<bennabiy>
have you ever used MATE on debian?
15:38
<vagrantc>
no need to reach me specifically
15:38
i have not
15:39
i prefer to stick with debian and not use external repositories
15:39
saves a lot of headache
15:39
<bennabiy>
that makes sense
15:40
<vagrantc>
but i prefer to help people in public channels... more people benefit that way
15:40
<bennabiy>
I agree

Just some channels are very much devoted to sticking to the topic of the channel, so other questions are not so advised.

<alkisg>
If you install the packages you want in one server, they get cached in /var/cache/apt/archives, and then if you just copy them to other servers before installing those packages, they will be read from the cache instead of pulled from the internet
15:44
<vagrantc>
there are some features like --mount-package-cache and --mount-package-lists and such to help
15:45
<bennabiy>
alkisg! would that work if I want different things installed to each?
15:45
<vagrantc>
for ltsp-build-client
15:45
<alkisg>
Sure, you only need to have the debs in that folder
15:45
Additional debs don't cause problems
15:46
And apt-get clean after installation deletes them, if you want to save space
15:46
<bennabiy>
What happens if I run apt-get update? would those packages in that folder be upgraded if there are new version and I run the upgrade?
15:46* vagrantc waves to alkisg
15:46
<alkisg>
Hi vagrantc :)
15:47
<bennabiy>
btw, alkisg: I finally got the audio fixed...
15:47
<alkisg>
If newer debs are available on the internet, those will be downloaded in the cache instead of the stored ones
15:47
Yup I saw it in the mailing list
15:47* vagrantc really wants to get that fix into debian
15:48
<bennabiy>
Is there a way I could go about getting a ltsp for mint setup, so I could post specific fixes which need to apply for mint?
15:48
at the moment, my build client has to build from ubuntu, but I think I could make a mint specific
15:49
I noticed on https://code.launchpad.net/ltsp I could download the codebase, but where would I go from there?
15:51
<vagrantc>
bennabiy: is ltsp-server available n mint?
15:51
ad ltsp-client?
15:52
the packages... they just don't work?
15:52
<bennabiy>
yes
15:53
it is the build client scripts which are not
15:53
<vagrantc>
probably just a few minor tweaks in /usr/share/ltsp/plugins/ltsp-build-client/
15:54
<bennabiy>
I have to do some magic redirection to cause it to pull the files for the client image and chroot from ubuntu instead of mint
15:54
that is what I thought
15:54
but it hasnt been done yet
15:54
and I do not want to have to keep doing it
15:54
;)
15:54
<vagrantc>
what does lsb_release say?
15:56
<bennabiy>
on the client?
15:56
or on my server?
15:56
<vagrantc>
on a mint comuter
15:56
er. mint install
15:56
<bennabiy>
No LSB modules are available
15:56
<alkisg>
lsb_release -sa
15:57brunolambert has left IRC (brunolambert!~brunolamb@64.254.228.2, Quit: Leaving.)
15:57
<alkisg>
Generally you can just file bug reports on ltsp to add simple things like supporting mint...
15:58
!ltsp-bug
15:58
<ltsp`>
ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
15:58
<bennabiy>
$ lsb_release -sa
15:58
No LSB modules are available.

15:59
<vagrantc>
although there's debian and ubuntu based mint, just tokeep it difficult
15:59
<bennabiy>
This is Ubuntu based
15:59
<alkisg>
The debian-based might report LMDE in lsb_release... we'll have to check
15:59
<vagrantc>
that'd be good
16:00
<bennabiy>
to make the distinction
16:00
<alkisg>
For starters, you could try symlinking /usr/share/ltsp/plugins/ltsp-build-client/Ubuntu to /usr/share/ltsp/plugins/ltsp-build-client/LinuxMint
16:00
<vagrantc>
when i have some free time i could set up vm and try it
16:00
<bennabiy>
alkisg that is what I do
16:00
<vagrantc>
you'll need a different 00base or whatever it's called
16:01
for the mirror defaults
16:01
<bennabiy>
and then when you build the client you need to specify architecture as well as release ( using the ubuntu release codename)
16:01
<vagrantc>
maybe a handfull of others
16:01
<alkisg>
Are the mint mirrors compatible or the same with the ubuntu ones?
16:01
Pastebin /etc/apt/sources.list ...
16:02
<vagrantc>
bennabiy: but you should be able to use mint mirrors and codenames
16:02
<bennabiy>
I know. but it has not been set up yet.
16:04
that is why I am wanting to set it up, and then have it available worldwide, because I am not the only mint user who does ltsp, although mint support of ltsp is not very well documented
16:04
<alkisg>
In your case it's worse, it's a mixed setup, mint server, ubuntu chroot
16:05
<bennabiy>
It is because the script has not been set up to pull actual mint chroot, but I think it is possible, and am willing to try it, if I know how to post my results when I do it
16:05* bennabiy is horrible at communicating
16:06
<vagrantc>
ltsp-build-client --copy-souceslist might be interesting
16:06* vagrantc wonders if mint debootstrap supports mint
16:07
<bennabiy>
hmm. isnt there an option to tell ltsp where to put the new build?
16:07
so I do not mess up my current setup
16:08
<vagrantc>
--chroot-name ?
16:09
<bennabiy>
!seen yanu
16:09
<ltsp`>
yanu was last seen in #ltsp 35 weeks, 5 days, 0 hours, 8 minutes, and 18 seconds ago: <yanu> fuzai: this is what I saved once :http://pastebin.com/Snt1tK4s
16:10
<bennabiy>
ltsp-build-client --base /opt/ltsp_new --copy-sources
16:10
--base
16:11
<vagrantc>
that's another way to do it
16:11
but then you'll need to reconfigure NFS or NBD to use the alternate location
16:12
<bennabiy>
I could make a special rule for my mac address to issue that image instead
16:13
<vagrantc>
yes, you'll have to configure dhcp in either case
16:14
ltsp-update-kernels with an alternate --base will probably break...
16:14
i.e. delete the kernels and initrd images
16:17
<bennabiy>
true.. perhaps I could just make a copy of the image files, remove them, and then try it... all else fails, move it back in place
16:18
those images only are needed to boot the client, right? So once the client is booted, those images can disappear and be replaced

ah
16:29
sources.list.d ?
16:29
<bennabiy>
let me check
16:30
yup
16:33* vagrantc wonders if --copy-sourceslist handles the .d dir
16:35
<bennabiy>
where is the documentation for that option?
16:37* vagrantc loked at the code
16:37
<vagrantc>
should also handle the .d dirs
16:37
<bennabiy>
ok
16:39
<vagrantc>
does /usr/share/debootstrap/scripts contain your release codename?
16:39
i think olivia?
16:47
<bennabiy>
nope
16:47
it has raring, which is a link to gutsy
16:49* bennabiy throws hands up in the air...
16:49
<bennabiy>
I give up trying to run my own repository for debian!
17:01* vagrantc wonders how mint does the base install
17:02
<vagrantc>
??
17:03
bennabiy: approx is really easy to set up
17:07
it's not strictly a mirror... it caches packages as you request them, so the second try is local
17:07
apt-cacher-ng is similar, but i haven't used it

bah, it is amazing what one letter does for a setting... I did 3096, not 3096M for grub
17:56
<vagrantc>
i've never needed more than 512M for dom0, but haven't run xen with wheezy
17:57
also always use dom0 for xend only, and run all services in domU
17:58
though i don't imagine it needs any more thanetch, lenny ot squeeze
17:58
bennabiy: why not kvm? no hardware support?

18:07
<vagrantc>
exactly what are you setting?
18:08
<bennabiy>
etc/default/grub -> GRUB_CMDLINE_XEN="dom0_mem=1024M" and then adding the same thing in xend-config.sdx
18:08
I mean the same number for dom0_mem
18:09
err dom0-min-mem
18:09
just without the M on it
18:09
<vagrantc>
i wouldn't change xend-config.sdx
18:10
<bennabiy>
I am just following https://wiki.debian.org/Xen
18:10

huh
18:11

I turned off ballooning and hard enabled the dom0 memory
18:11
those are my only changes

18:20
<alkisg>
Thin chroot?
18:21
<bennabiy>
yes
18:21
<alkisg>
Try --copy-sources-list and symlink Ubuntu to LinuxMint...
18:21
Not sure what else is needed
18:22
Also --mount-package-cache for speedup
18:27
<bennabiy>
I am thinking I should use the --chroot to differentiate between the ubuntu clients I already have and the new attempt
18:27
does the order of arguments matter?

I already have the directory symlinked

that is how I made the client in the first place
18:56
but then when building the client, I needed to specify --dist=raring or it would not build, so it built a raring client
18:57
but I want to see if I can make an olivia client
19:11
Does that make sense?
