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.

[Bug 1373] killer freezes thin client sessions
http://bugs.skolelinux.org/show_bug.cgi?id=1373 r...@gmx.de changed: What|Removed |Added URL||http://lists.debian.org/debi ||an-edu/2009/09/msg00110.html Summary|killer seems to be too |killer freezes thin client |trigger happy. |sessions --- Comment #3 from r...@gmx.de 2009-09-20 19:48 --- 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?

Re: does killer kill ssh sessions? / Re: Strange LTSP phenomenon: Clients sessions freeze
[Ralf Gesellensetter] The bug report exists: 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.

ksoftirqd blocks CPU
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.

Are the users logged in using ssh seen as logged in users (aka the output from who)? 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?).

RFS: texttrainer
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 -- Pungenday, 44th of Bureaucracy, 3175. jacob kanev eMail: j_ka...@arcor.de (any eMail with attached Microsoft-only files will be regarded as spam) -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.

upload debian-edu 0.838 ?
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 -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.
