Diamond is my personal firewall. It was based on the
Linux Router Project and
booted from a floppy disk (read only).
The firewall was also connected to a old matrix printer that logs all
strange behaviour. So if you do any suspicios with my computer system I'll be
warned because this printer sounds a lot! And if someone successfully crack it
I just have to reboot it because I have a write protected floppy that
it runs from.
Now I have changed to a Debian installation to make it more powerful and
easy to administrate. An other reason was the there were no dirvers available
in LRP for my more recent network adapters.
