ptxArchiver 0.3 is out. I added the possibility to not insert the delete statement in the binlog for replication. I also fixed some minor bugs. give it a try and send me your feedback :)

dstat and my.cnf

What a surprise, this week-end I received I very nice email asking me some help on the plugins I wrote for dstat. I wrote them more then 2 years ago while listening to Linus Torvalds in Cambridge :) The request was to enable the read of the password and user from the my.cnf file instead of exporting them in environment variables. Here are the patch for the release 7.x (fedora) and 6.x (centos 5.3) The patch is only for one of the plugin, but it's easy to apply it to all of them.

ptxArchiver 0.1 released !

ptxArchiver 0.1 is released, this tool uses mk-archiver from maatkit to archive tables into another table, a file or simply purged BUT it follows the foreign keys defined in a config file and archive then the linked table. Feel free to test it and report improvements, comments, encouragement :) Special thanks to zipkid for the help reviewing some code.

cyrus on debian

I had to setup a nice mail solution for friends on their GNU/Linux server: a nice Debian 4.0 :-) As you should know, I'm not a Debian afficionados, never knew why but this is not my favorite distro and this is where the opensource world takes all his sense: freedom of choice :) "...tous les goûts sont dans la nature..." Ok then I started to setup ldap, not really a problem, the 4 db's were inserted via ldif; postfix with ldap support for domains and users was also not problem. Cyrus and Sasl was ok untill I discover that the autocreate patch[1] was not present in the package... oh my root ! As I didn't want to install cyrus from sources, and as I wasn't able to find a package already patched (but I found a huge amount of bugs requesting that feature and this for all cyrus version, it seems that postfix's debian maintainers don't like that patch... but I guess that all the other common distros have the patch included in their package...) Ok then I started to try to remember how to make a .deb again (loooooong time ago) step 1: apt-get install devscripts step 2: apt-get source cyrus-imapd-2.2 (I know it's old :( ) step 3: create a dpatch (cat ~lefred/cyrus-imapd-2.2.13-autocreate-0.9.4.diff | dpatch patch-template -p "85-autocreate.dpatch" > cyrus-imapd-2.2-2.2.13/debian/patches/85-autocreate.dpatch step 4: add 85-autocreate.dpatch between 80-kbsd-no-psstrings.dpatch and 99-update-autoconf.dpatch in cyrus-imapd-2.2-2.2.13/debian/patches/00list step 5: apply the patches : cd cyrus-imapd-2.2-2.2.13; dpatch apply-all -v step 6: build the packages : dpkg-buildpackage -uc ARRGH it fails : reverting patch 85-autocreate from ./ ... failed. step 7: rm debian/patched/85-autocreate.dpatch step 8: redo step 6 ARRGH it fails again, it seemd the dpatch creation is not ok I found another dpatch [2] and I replace it, so step 3 can be replaced by the copy of the new 85-autocreate.dpatch into cyrus-imapd-2.2-2.2.13/debian/patches/ Then back to step 4 and everything works ! in the mail.log using the standard debian package : Oct 15 20:12:53 ns2014675 postfix/pipe[6186]: 6506571620: to=, orig_to=, relay=cyrus, delay=0.08, delays=0.03/0/0/0.04, dsn=5.6.0, status=bounced (data format error.

EeePC synchronization with unison

Sometimes I use my EeePC during a meeting, or when I don't want to use my bigger Dell laptop. But of course I'd like to be able to synchronize one folder on both machines to transfer documents that I should update on both laptops. unison is my friend for this task, but as I'd like to test some avahi and libnotify code to automate and integrate this solution on my gnome desktop, I wrote the following python script : EeepcSync Instructions on how to use it are present in the script. Somes screen captures : of course the code should be reviewed as I'm very newbie in python ;-)
