Very old stuff (2000-2009), mostly not accessible anymore:

  • OBPkg: a Synaptic-like tool for OpenBSD
  • cwa: a web programming system for C (like PHP, but you can run C code instead)
  • cchttpd: a highly speed-optimized HTTP server, capable of loading C modules to perform server-side website generation and request handling
  • xyriaDNSd: a highly speed-optimized DNS server with load-balancing capabilities (old version from 2008 available on sourceforge)
  • sysmon: web-based system monitoring tool for Solaris 8
  • MSS: Multiple server scanner (a port scanner supporting various scan types; written ca. 2001 with friends)
  • cpfos: An extended Slackware-based packet system for Hardened Linux
  • fupids2: a user-space version of FUPIDS (see above)
  • various hacking tools, mostly to learn how to handle sockets under Linux and BSD, incl. a RIP routing update spoofer, some PoC backdoors using covert channels, and a a simple TCP connection hijacker.

Maintainance of OpenBSD Ports

I contributed the `pscan’ port (a C code vulnerability scanner) to OpenBSD .

Patches for Other Projects

I contributed several patches to the Open Source Software (OSS) community, including mostly bugfixes but also few feature improvements:

  • Operating Systems (packaging/build scripts, tools, …):
  • Tools: gftp, icmpinfo, Ping Tunnel
  • A number of manpage fixes (mostly Ubuntu/Debian)
