Debian-related Tinkering

I've been a fan of Debian for a number of years, using it for my primary operating system since 2001. This is a collection of tricks or customizations that may be useful for people, but which don't belong in Debian mainstream.

fixing ugly fonts
Some of the default font configuration is painful. How to fix it.
logcheck customizations
A collection of filters for logcheck that make it less noisy. The out-of-the-box configuration gives too many alerts and lowers the signal/noise ratio.
ssh rate throttling
A simple iptables script that simply rate-limits all incoming ssh (or any TCP) connections. Useful for dicouraging ssh brute-force attempts.
