Enslaver: in debian/ubuntu there's an "ldm-server" package
Enslaver: which has an inetd hook to get session information from the server
also language information and such
Enslaver: yeah, LDM_SERVER
berryterminal seemed really limited, and didn't even boot when i tried it
whats the deal with ltsp-cluster? is that project ongoing?
i think so... never really had the time to check it out in detail.
Enslaver: well, good chatting with you. need to head out again

good morning friends
i'm spending time today digging through how LTSP-5 works. I figure it's about time I understand it
first thing i'm wondering...
the ltsp-update-kernels script copies the kernel and sets up the pxelinux config files in 2 places
in /var/lib/tftpboot/ltsp and in /srv/tftp/ltsp
i'm wondering why it's putting the same stuff in both places?

Meh I was answering to myself :-/
(06:08:48 μμ) alkisg: jammcq: basically it doesn't know where to put it
(06:09:03 μμ) alkisg: You might be using dnsmasq, tftpd-hpa etc etc,
(06:09:12 μμ) alkisg: or you might have a custom dir in your tftp dir,
yeah, I figured you were just ignoring my lame question :)
(06:09:27 μμ) alkisg: so we have 3 frequent dirs where the tftp files *might* reside,
(06:09:40 μμ) alkisg: and the code puts the files in whichever of those dirs is available
(06:09:48 μμ) alkisg: Typically, you'd have only one of those dirs
(06:10:00 μμ) alkisg: E.g. in ubuntu you shouldn't have /srv/tftp
(06:10:11 μμ) alkisg: And then ltsp-update-kernels doesn't create that dir, nor does it put files there
(06:10:41 μμ) alkisg: On the other hand, if you have e.g. 2 tftp servers and you manually run one or the other, you create both dirs and ltsp-update-kernels puts the files in both dirs
my debian system has the /srv/tftp and the /var/lib/tftpboot/ltsp
dpkg -S /srv/tftp; dpkg -S /var/lib/tftpboot
Or just delete one of them.. or make one a symlink of the other... or ignore them :D
root@ltsp:~# dpkg -S /srv/tftp
dpkg-query: no path found matching pattern /srv/tftp
back in the days of ltsp-4.2, I knew every bit about how it worked
now... i'm mostly lost
So no package ships /srv/tftp, it's created by some package's postinst
I think /srv/tftp is the new trend in debian, so you can just delete the other one
I'll just leave it, this is just a test server for me to play around

alkisg: hi, I've a little problem with your ppa
gpgkeys: key 4F3A3E9FC07F4E831D87AC2D3C72607B03AFA832 not found on keyserver
(hi, I'm at school at the moment with a teacher behind me ;P)
alkisg: any idea?
markit: apt-key list | grep ts.sch.gr
Which ubuntu variant/version is that?
apt-key list | grep ts.sch.gr is empty
is 12.04 32 bit
there have been added a google repo for chrome (sigh)
markit: it looks like some local issue, it works fine here,
so I suppose it would work e.g. tomorrow,
...but here's an alternative way to add the key:
can I ignore the signature problem?
wget http://ts.sch.gr/repo/add-ppa.sh -O /tmp/add-ppa.sh && sh /tmp/add-ppa.sh ts.sch.gr
(if I remember it right - try it)
ok, now apt-get update gives NO error, but apt-key list | grep ts.sch.gr is still empty
btw recv failed also in other ppa
Ah sorry wrong grep there
Yeah it seems like a local problem there
markit: pub 1024R/03AFA832 2009-05-27

Grep for 03AFA832
If you have that, you have the key
I'm converting a thin ltsp without your repo to a fat ltsp with your repo
markit: errr remember that upgrading from 12.04 to our ppa is hard
Quick how to: (1) purge ltsp, tftp, nbd-server,
(2) delete all settings from /etc/ltsp, /etc/nbd-server etc,
(3) and then put our repo and install the new ltsp with the new configuration settings etc
yep, thanks , just forgot to purge also nbd-server
time to go, bb all

I've entered fat chroot with ltsp-chroot and -c flag, neverless seems is fetching a lot of packages (I'm installing programs that are in the server) from internet and not from apt cache, any idea?
markit: you mean from the server's /var/cache/apt/archives ?
i.e. ls -l /var/cache/apt/archives/ | grep gimp-help-it
shows the package gimp-help-it_2.6.1-1_all.deb
and in chroot I've
Get: 51 http://it.archive.ubuntu.com/ubuntu/ precise/main gimp-help-it all 2.6.1-1 [31,0 MB]
is /opt/ltsp/i386/var/cache/apt/archives mounted?
I've added repos in chroot (same as in server) and started updating / installing without exiting... coult it be a problem?
should be fine.
if the file is there, it should check it against the version/checksum that it knows about.
I see with #mount in server: /var/cache/apt/archives on /opt/ltsp/i386/var/cache/apt/archives type none (rw,bind)
and arch: all packages should always match.
ls /opt/ltsp/i386/var/cache/apt/archives/ | wc -l ; ls /var/cache/apt/archives | wc -l
come up with the same numbers?
vagrantc: I've done an aptitude full-upgrade before entering chroot, so should be updated
mmm probably the date of the package in cache is not when was downloaded but the original one from repository?
I should check it's presence before chroot starts downloading, maybe
vagrantc: ok, probably cache does not contain all package, sorry for the noise
btw, I've learned something about the "mount" stuff, thanks
markit: so it might be working?
if it's mounted, and they contain the same files, i'd be surprised if it wasn't working.
more likely something ran "apt-get clean" at some point.
that's why i prefer a caching proxy, such as approx.

vagrantc: yes it's working, just host cache has not all the package of installed programs in the cache, sigh
and this internet connection is slow like hell :(
also today I've discovered that squid is blocking ppa keys fetching, and I've disabled it after struggling a lot before find the culprint
squid can be troublesome.
yes, and now, in a school of a friend of mine, squid authentication is needed, but I've found can't be setup if you config it as transparent proxy, that is what I do
i don't let squid cache any files, because it usually gets it wrong. use a transparent squid proxy with jesred to redirect it to approx for urls that look likely to be packages.
approx knows what a debian-style mirror looks like, so it can cache things intelligently.
mmm I've used squid since day 0, I use it at my home, and works fine
recently I've installed something-ng for apt cache, never heard about approx, will investigate later
it always has out of sync Release and Packages files, which breaks a lot of things, and always throws out the packages i wanted to cache, even when there's plenty of room left.
apt-cacher-ng is another one, haven't tried it recently.
I need squid for web navigation
slow internet connection, so I have to use it at it's best
even would love to install flash-blocker globally, but the package was in ubuntu time ago and now is no more there
|22:31||PandaSparky has joined IRC (PandaSparkyfirstname.lastname@example.org)|
vagrantc: so you suggest approx for packages, and squid NOT in transparent for web navigation, right?
as transparent it blocks keyserver.ubuntu.com connections :(
(or at least did, maybe now that I've reinstalled and refreshed the cache will no anymore, yet to test it)
|22:34||PandaSparky has left IRC (PandaSparkyemail@example.com, Remote host closed the connection)|
markit: i use squid transparently, but it doesn't cache anything, but redirects some things to approx.
markit: so approx does all the debian/ubuntu package caching and related files.
