AccountPolicy Set NT User Account Policy from command line. This is obsolete and hasn't been changed for years, but people seem to still occasionally use it. (It can do a couple of things the native tools can't, such as setting the lockout duration to "forever", and annoying someone by making their password expire every 3 minutes :-) Update: a couple of bugs were reported and fixed on 2004-06-10, about 6 years after I last looked at this. Apparently it's still marginally useful...

OpenSSH I'm one of the developers, and here you can find some patches, AIX SMIT/installp installable packages and other information. There are also some old patches that are no longer maintained, but may be of interest. Because of my OpenSSH work, I'm also an OpenBSD developer, although to date this has been mainly working with the ssh components.

OpenNTPd Starting after 3.5, OpenBSD acquired a small, secure NTP daemon written by Henning Brauer and Alexander Guy. I have added autoconf and a portability layer, and currently the result runs on Linux, FreeBSD and Solaris as well as OpenBSD. There has been far more interest in this than I anticipated: henning created a website, and before it has even been officially announced, there has been a FreeBSD Port (thanks to naddy, who also helped with some build fixes), a FreshMeat page created and an article at undeadly.org.

ReverseProxy patch for rewriting HTTP redirects (Using Apache, mod_perl and ReverseProxy.pm).

Misc Patches Patches for stuff that doesn't fit elsewhere.


Unix process-level debugging How Unix debugging tools were used to track down a low-level problem with IBM Tivoli Remote Control, written as a mini-tutorial.

Other Stuff

I have ocassionally been know to play cricket (badly), as a bowler of indifferent off-spin, wildly erratic leg-spin or specialist No. 11 batsman.

I have an advogato page with an infrequently-updated blog, mostly relating to work on free software.
