First steps with Subversion’s new merge tracking

A while ago we succeeded in upgrading the Debian server where I keep many of my SVN repositories. (The server was running on “testing”, but we hadn't dared to upgrade it for a long time until it came time to make it “stable” again with Lenny.) On of the upgraded packages in Lenny is Subversion, now at 1.5.1, which means that I can finally start using subversions new merge tracking features. Read More »

Configuring Nagios to check a HTTP host

Nagios is an elaborate piece of software to monitor hosts and services. I will explain a bit how you can configure nagios to monitor an HTTP service. I'm assuming your nagios setup already has the default config files generic-host_nagios2.cfg and generic-service_nagios2.cfg, which tell nagios how to monitor hosts and services. Read More »

Disable Zimbra’s duplicate mail detection

Fixing spamassassin rule in Zimbra

Spamassassin has had a bug for a while, marking any mail from 2010 and later as spam because it's from "far into the future". This was very crudely done as this regexp: /20[1-9][0-9]/. Because of that, almost all mail from 2010 onward is marked as spam. Read More »
