Any BFD/AFP softwares available for FreeBSD 4.10?

If you would update to a recent FreeBSD Release, you could probably use some nice pf(4) things...

Im getting flooded with ssh and ftp attempts.

I recently stumbled over quite a nice pf.conf (see man pfctl for details), which blacklists for instance ssh connections if the occur to often in a certain amount of time.
For Example:
# sshspammer table
table <sshspammer> persist
block log quick from <sshspammer>

# sshspammer
# more than 6 ssh attempts in 15 seconds will be blocked ;)
pass in quick on $ext_if proto tcp to ($ext_if) port ssh $tcp_flags (max-src-conn 10, max-src-conn-rate 6/15, overload <sshspammer> flush
global)

HTH,
Marian
