-  * Traffic shaping a standard ADSL link in order to share it with a couple of hundred users is a common problem. There are dozens of bits of software and firewall scripts out there already to do this. This particular page details a method that I have used successfully for several years. It aims to be as simple as possible, is easily customised, and uses connlimit to identify P2P users. Although the latter is not 100% reliable, it seems to work pretty well and does not fall foul of any new/changed P2P software that happens to some of the other scripts. The page is written as more of a tutorial; if you would like to use this in practice, then I recommend you check out the scripts in the "​captive portal from scratch"​ page below.

-  * The original idea of this page was a quick and dirty howto on how to setup SMTP authentication on Postfix. However, it turned out that there was no quick way to achieve what I wanted (encrypted passwords over an unencrypted link, using Courier IMAP as the password database). It also turned out that I was running a non-standard Postfix (it wasn't chrooted). Therefore, as SMTP AUTH and SASL have always been something of a black art to me, I have written a few things down that I have discovered, as well as a quick and dirty howto on setting up a basic SASL database.
