Projects @ Mindrot.org

Projects and quick hacks that (to some extent) live here include:

Portable OpenSSH

The port of OpenBSD's SSH protocol implementation to other POSIX operating systems (including most Unices and Windows via Cygwin).

flowd

A small, fast, secure and featureful NetFlow™ collector daemon. [moved to Google Code]

pfflowd

Cisco NetFlow™ datagram export for OpenBSD's PF packet filter.

flashboot

A set of makefiles and scripts for building small, customised OpenBSD distributions suitable for running off read-only boot media (especially flash). Based on OpenBSD's install floppy build system.

Softflowd

This is a software implementation of Cisco's NetFlow™ traffic accounting protocol. It collects and tracks traffic flows by listening on a promiscuous interface. Designed for minimal CPU load on busy networks. [moved to Google Code]

Miscellaneous Code

Various other things developed or patched here, including Python modules:

• py-radix - Radix tree data structure for Python. [moved to Google Code]
• py-bcrypt and jBCrypt - OpenBSD-style Blowfish password hashing for Pythoni and Java. [moved to Google Code]
• py-editdist - Levenshtein edit distance calculation for Python. [moved to Google Code]
• passwdqc - Password complexity checking plugin for OpenBSD
• Some older junk too...

Traffic-vis

A suite of network traffic monitoring tools, which can write reports in a number of formats. Largely unmaintained.

OpenBSD-related things

Patches and config snippets related to OpenBSD.

SSH Protocol, Tips and Tricks tutorial

In 2002 I was invited to give a tutorial at the Australian Unix Users Group's Winter conference introducing the SSH protocols, the OpenSSH implementation and demonstrating some of the its fundamental and more advanced uses. The slides and the tutorial notes are distributed here in a number of formats which I occasionally update to keep abrest of continuing development.
