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).
A small, fast, secure and featureful NetFlow™ collector daemon. [moved to Google Code]
Cisco NetFlow™ datagram export for OpenBSD's PF packet filter.
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.
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:
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.

Recent updates

Bah. The last release won't boot on the Soekris boxes as the kernel + ramdisk size requires an increase in the number of kernel page table pages and removal of ISA DMA (no memory left below 16Mb). A new flashboot-0.9alpha1 release has been made to correct this.

flashboot-0.9alpha has been released. This release adds a kernel for the Commell LE564 SBC and syncs flashboot to OpenBSD 3.8-current (not -stable).
