Why don't you have sshd listen on a different port? I was getting
1000's of ssh login attempts until I changed the port sshd was
listening on. I've found script kiddies aren't smart enough to check
alt ports.

Does anyone know of a utility that I can use with sshd to auto-block
by IP if
there are more then N failed attempts in a row?
ie:
# grep "Invalid user" /var/log/auth.log| awk '{print $10}' | sort |
uniq -c |
sort -nr

649 59.77.33.139
381 201.80.15.207
269 190.10.255.73
212 81.252.254.189
181 123.151.32.12
150 211.21.47.50
139 196.219.63.3
128 200.111.64.171
This is for one day ... I'd like to be able to throttle so that
after X Invalid
user attempts, the IP gets blocked ...
Possible?
