Klaus supported my suspect, that killer is the killer.
José's idea that the ssh session was killed came also into my mind.

I think there was a howto for plain sessions (no ssh afer login).
Is there a howto for killer? A file to place exceptions (don't kill 
processes of user X/named Y)?

Next time (1 week from now) I would try the thin clients' console.

Til then, I need to live with or without killer (what would be worse?), 
or adapt the cron job timing to school intermissions...

Hi there, 

I could confirm that the cron.hourly script runs exactly * 17 every hour 
- so that was the time the freeze occured.

Starting debugging by apt-get source killer gave me a perl script.
Searching for a significant comment string, google found only one U* man 
page:

http://manpages.ubuntu.com/manpages/karmic/man1/killer.1.html

It contains a dead link to 
http://homepages.cae.wisc.edu/~gerdts/

I will try to use the -n option to file some logs...

Regards
Ralf

I can confirm this. All sessions frozen at 2:17 and 3:17 p.m. which was exactly
the time when the hourly cronjob was run. No network issue, as I could check in
a simultaneous ssh session, and re-boot of thin clients was possible at once.

In order to debug this further on, I need more information on how to use/config
the killer perl script  /usr/sbin/killer

I found a man page at [1] pointing to a dead URL.

Accordingly there are options for debugging, but apparently no
option to list processes or users that are not to be killed.

Also peeked into killer-sources; there are some patches, but I didn't figure
out their meaning entirely.

Where is killer logging to, by default? Syslog?

Cheers
Ralf

[Ralf Gesellensetter]

 http://bugs.skolelinux.no/show_bug.cgi?id=1373

Good.

Are the ssh sessions showing up when executing 'who'?  The killer
program kill prosesses for non-existing and logged out users.  Are the
users logged in using ssh seen as logged in users (aka the output from
who)?

The issue Klaus Ade reported on IRC was that a flaky/overloaded LDAP
server might some times report that an existing user did not exist,
and if that happened when killer was running, that users processes
were removed.  It might be an idea to rewrite killer to only kill the
processes for an unknown user if the user is unknown for a period of
time, to avoid this problem with flaky LDAP servers.

Happy hacking,

ksoftirqd blocks CPU

2009-09-20 Thread RalfGesellensetter
Good evening,

I prepared some debugging/logging to watch what killer is about to do 
during the week.

Now, I realize, that once again 1 CPU is blocked by ksoftirqd:

PID USER  PR  NI  VIRT  RES  SHR S %CPU %MEMTIME+  COMMAND
  7 root  15  -5 000 R  100  0.0   2945:13 ksoftirqd/1

Also, dmesg/syslog gives some alarming/frightening messages. May anybody 
please have a look at

http://paste.debian.net/47108/

and tell me, what your experienced eyes see?
I am running a AMD64 Opteron dual core with corresponding kernel:

2.6.26-2-amd64 #1 SMP Sun Jul 26 22:49:57 UTC 2009 x86_64 GNU/Linux

BTW: While writing this, the ksoftirqd process has calmed down...

Thanks anyway.
Wondering
Ralf

Hey Petter,

I can't check now (of course), but I'd rather think that only regular  
sessions (ssh, local login) are shown by who. (And there is processes 
like softirqd that are not shown by htop, but by top.)

Is there any explanations of the output of killer -d ?
What does killer print to stdout if it is triggered?
Why does killer depend on exim BTW? It would be great if I could be 
warned in emergency case by email, but I didn't read that the mailserver 
could be fixed so far (maybe my fault missing that good news?).

Thanks

since debian-edu's rules file is a one-line include on cdd-dev (now

then other packages built with those tools would also gain the benefit.

RFS: texttrainer

2009-09-20 Thread Jacob Kanev
Dear mentors,

I am still looking for a sponsor for my package texttrainer [1]. A new 
version has been uploaded to MDN.

* Package name: texttrainer
  Version : 0.0.4-1
  Upstream Author : Jacob Kanev j_ka...@arcor.de
* URL : http://home.arcor.de/j_kanev/texttrainer
* License : GPL 3
  Language: C++ / QT4
  Section : misc

It builds these binary packages:
texttrainer - learn native or foreign language texts by heart

The package appears to be lintian clean.
The upload would fix these bugs: 545811 (ITP)

The package can be found on mentors.debian.net:
- URL: http://mentors.debian.net/debian/pool/main/t/texttrainer
- Source repository: deb-src http://mentors.debian.net/debian unstable main 
contrib non-free
- dget 
http://mentors.debian.net/debian/pool/main/t/texttrainer/texttrainer_0.0.4-1.dsc

I would be glad if someone uploaded this package for me.

Kind regards
 Jacob Kanev

[1]
Description: A program which helps you memorise poems or plain texts in your 
native or in some foreign language. You learn by repeatedly reading the text, 
while after each run more (and different) words are being hidden (i.e. replaced 
by _). This will teach you a poem, parts of your text for a play, or  basic 
phrases of a foreign language before you go on holiday. Different learning 
curves may be selected, and for foreign language texts there is an automatic 
grammar correction. Data  files for TextTrainer can contain the plain text, as 
well as translations and pronounciation guides. Data files can be created with 
TextTrainer itself, or with any standard text editor

Thanks for raising awareness of this bug.

What I do for all the packages that I (co)maintain is to add the 
attached file as debian/cdbs/1/rules/buildinfo.mk and add the following 
line to debian/rules:


include debian/cdbs/1/rules/buildinfo.mk

Less is possible too.  For those favoring custom maintaining more parts 
of their packaging routines over using CDBS.

upload debian-edu 0.838 ?

2009-09-20 Thread Vagrant Cascadian
the last upload of debian-edu (0.837) to Debian was Wed, 16 Jul 2008 11:53:30
+. since then, debian/changelog has accumulated nearly 200 lines of
changes, and includes a several fixes for bugs in the debian BTS, three of
which have been marked pending for nearly a year or more.

i understand that while preparing a lenny-based release, all of the issues that
should get fixed in unstable probably can't be done (such as the bug regarding
updating KDE dependencies).

it seems like an upload to Debian unstable could still resolve a few bugs,
lintian issues, and generally bring the skolelinux and debian repositories even
closer in sync. we'll also gain the vigilant watch of various automated tests
(piuparts, buildds, lintian.debian.org, etc.) and other people looking for
issues which could benefit the lenny-based release.

i'd be happy to prepare an upload for 0.838, if a DD could sponsor it, after
which i'd be able to make uploads directly as a DM.

live well,
  vagrant
