check_md5 {check_md5 }
My third Nagios plugin. This one is a small security plugin to check the MD5 sum of a single file. It's written in Bash and issues a critical state in case of a MD5 mismatch. This behavior can be change by setting the --warning flag.

check_gputemp { check_gputemp }
My second Nagios plugin I've written. This is based on check_temp which I wrote earlier this year. This plugin checks the GPU temperature of ATI graphics card using their tool aticonfig from their fglrx driver. As with check_temp this plugin complies with the Nagios plugin development guidelines.

check_temp { check_temp }
My very first plugin I wrote for Nagios. It's a simple Bash script that checks the CPU temperature by default but can be changed to motherboard temperature instead. The script complies with the Nagios plugin development guidelines.

rMachines { rmachines01.sh | README
rMachines is a small Bash script to collect uptime and who data from remote machines over SSH, and then write these data to a simple HTML file. Also see the projects SourceForge page.

SSH Block 2 { ssh_block2.sh | sshblock2.txt | readme.txt | readme_solaris.txt }
This is the latest version of my SSH Block script. It's a small Bash script made to block automatic probes of SSH usernames. Development of SSH Block 2 has somewhat started again. Check out the SourceForge project page at http://sourceforge.net/projects/sshblock2/

BlueWebPro { bluewebpro.sh | bluewebpro_wrapper.sh }
Very similar to SSH Block, but instead of blocking SSH probes it blocks known web attacks. It searches Apache logfiles for known pattern.

BlueBackup { bluebackup.sh }
A (very) simple backup script for various Linux/*nix dists

BluePass { bluepass.sh }
Another very simple script. This one checks your Linux system for passwordless accounts.

EncMount { encmount.sh }
Small script to provide a simlpe GUI for mounting encrypted volumes. Dunno if it still works, only tested on OpenSuSE 10.2
