Here's what I've been working on lately:

Kerberos Challenge Response Authentication Protocol

This is basically to allow samba encrypted password hash authentication through a kerberos database.

IDB (Instrumentation Database)

CDMA2000 Parallel Simulation

FreeBSD's NEWCARD

Better SASL support for nmh

Changes to the nmh sources to get more sane SASL support.

Kerberos 5/GSSAPI patches for elm

Lets elm authenticate with POP/IMAP servers using GSSAPI and Kerberos 5 tickets.

Nagios check_krb5 plugin

Nagios plugin to check status of Kerberos KDC server

FreeBSD

When I have time, I like to hack on various parts of FreeBSD.

SSH 1.2.14 for Windows

You may be looking for an old version of SSH 1.2.14 for Windows that I compiled a while back. I no longer have a copy of the binaries, nor do I know where to get them. In any case, get better versions at freessh.org.

PAM patches for SSH

PAM is now integrated in all recent SSH versions I know of.
