A random collection of things I've made for myself.

• PDF version of an overview of subnetmasks, slashes, number of hosts and so on. Handy to print out and hang on the wall.
• Code Red and Nimda spammer-1.2, a shell script which takes the output of the apache-logfile and sends a warning to people who are related to that host and/or domain about infections of their IIS servers.
• HTTP grabber-1.0. httpgrabber saves the information being sent via the HTTP protocol on disk. In other words, you can use it to see what other people on your LAN are downloading.
  For more information, read the man page.
  
• IPFW grapher-1.4. Displays a graphical overview of bytes going through your IPFW rules and a piled overview of the percentage on which rule it passed.
  See a sample graph. The first tab is all the rules, the second is the deny-rules only and the third is the allow-rules only.
  For more information, read the man page.
  See CHANGES for a list of changes.
