How-To Documents
  • Securing Apache — This comes from an article that was originally published in SysAdmin Magazine in May 1999. I'm working on a more comprehensive document that will replace this one. I'm keeping this one around for now because people seem to be interested in the discussion on setting up a chroot for web servers.

Sample CGI Scripts
  • file_upload.pl — Perl script that demonstrates how to handle file transfers from HTML forms. It's heavily commented to explain how it works.

Miscellaneous Utilities
  • hideaddr.c — A very simple command-line utility to encode your email address in the hopes of fooling spammers' address harvesters. Encoding your email address in this way is not a guarantee that address harvesters won't find it. Any of the tricks people use (e.g. "kyle at example dot com") to hide email addresses on web pages are susceptible to smart harvesters, but this has the advantage of looking normal to users through their browsers.
