Software

I like to write open-source software, and you can find most of my projects on Github:

fping: I am the maintainer of the fping command-line tool.
Postgrey: Postfix Greylist Policy Server.
Mailgraph: a RRDTool front-end for Postfix statistics.
Pingmachine: An asynchronous monitoring framework.
Gedafe: "Generic" database front-end for PostgreSQL, that I developed together with Tobias Oetiker.
ISGTC: The ISG Toolchest (ISGTC) is two things: a policy about how system administration scripts should be written and a set of scripts that follow this policy.
Config::Grammar: Perl module to parse configuration files and provide helpful error messages.
Parse::Syslog: Perl module to parse Unix syslog files.
Text::FormatTable: Perl module to render tables into text.
