From the chapter Things, that are so obvious... once they failed

Configuring your monitoring system via DHCP, and wondering why the malfunction of one single server can cause so dramatic alerts in your entire infrastructure.

Slides from CLT talk available

The slides from my talk at the Chemnitzer Linux-Tage are now available. As promised I added additional screenshots of the parts I showed directly.

Again many thanks for showing up in my talk and the feedback I got so far!

Update: I should mention, that the topic was Projektmanagement mit Subversion und Trac and the talk as well as the slides are in German.

Dear Lazyweb,

Since a recent update of one of my systems, amavisd-new keeps on spamming me. I get mails containing stuff like bayes: synced databases from journal in 0 seconds: 674 unique entries (742 total entries). The reasons seems to be a cronjob from amavisd-new (which can be deactivated via debconf):

grep amavisd-new-cron /etc/cron.{d,daily}/*
/etc/cron.d/amavisd-new:18 */3  * * *   amavis  test -e /usr/sbin/amavisd-new-cronjob && /usr/sbin/amavisd-new-cronjob sa-sync
/etc/cron.daily/amavisd-new:test -e /usr/sbin/amavisd-new-cronjob && exec /usr/sbin/amavisd-new-cronjob sa-clean

However, the called script contains:

egrep "sa-sync\)|sa-clean\)" -A 2 /usr/sbin/amavisd-new-cronjob
                do_amavis_cmd "/usr/bin/sa-learn --sync >/dev/null"
                do_amavis_cmd "/usr/bin/sa-learn --sync --force-expire >/dev/null"

Note that output is redirected to /dev/null, so I should only mails if an error occurs, shouldn't I? I'm really baffled... To the best of my knowledge I shouldn't get these mails. Where am I wrong, and how to formulate that in a bug report?

Have fun with Lenny!

PS: Next time, if we release on Valentines, let's choose a single to fly around the globe just to send some mails out...

localhost nagios checks via nrpe

I'll write it down, so maybe I won't forget it: If you want to check localhost via Nagios nrpe (e.g. because you are lazy and want to reuse all the nrpe configuration you already have for other hosts), but it fails with CHECK_NRPE: Error - Could not complete SSL handshake., then make sure, that you allowed in your allowed_hosts.
