- Using one time passwords to temporarily open firewall ports
- I use Xen to create multiple locked down virtual machines that to run services which I want to present to the internet I do not allow direct connections from the internet to my firewall but sometimes there's a need to do remote administration (via ssh) so I can temporarily open up one or more ports. This I do with a webpage where an OPIE (one time password) challenge should be entered.
- Debian Administration website design contest!
The current look of this site hasn't changed much for the past two years, apart from a few additional CSS rules being used by default in article texts. Whilst the content here is hopefully of sufficient quality to allow the current design to be tolerated I'm sure we can do better.
- MIT Kerberos installation on Debian
The purpose of this Guide is to give you a straight-forward, Debian-friendly way of installing and configuring Kerberos. We will go through introduction to Kerberos, installation, configuration, PAM config and setting up of encrypted telnet/ftp session to the server. We will show how to use Kerberos logins as a replacement for SSH keys, and how to use standard (optionally encrypted) telnet/ftp connections instead of SSH.
- Making shell scripts executable via editor hooks
If you spend a lot of time creating new shell scripts, be they plain shell or scripting languages such as perl or python, then it can be very useful to make new scripts be executable by default. Here we'll show two simple recipes for GNU Emacs and vim to do just that.
