Sounds more like you want firewalling.
What exactly are you trying to do?

i read somewere to make you computer harder to hack or more frustrating you can bind a bunch of ports to /dev/null or trick port scanners into thinking you have 100 ssh ports open.

Surely you mean crack ;)
You can do such tricks with iptables (firewalling) and such. Also google "honeypots" & "tarpits" if you want to muck with the people trying to crack your system.

On a similar note, I frequently am attacked in excess of 500 times a day via SSH. In addition, my friend was recently assaulted all day long, resulting in excess of 5000 attempts before he added a block to his firewall. It's a growing issue and I know I heard about some software to block out repeated failures with sshd (can't remember what it's called, I remember I was using 10k at the time and it required a higher python version than I had). Might be something interesting to add to the repo.
Thanks,
Stephen Clement

I had that problem. It isn't anything other than annoying - I mean, the security risks are very low as I am running a server with only 15 or so users, some of which don't even have shell access anyway. I ran across some script (can't remember anything about it) that added a firewall rule after 5 failures. Seemed a bit cumbersome, however, so in the end I gave up and hoped for the best.
Bizarrely, all the attacks appeared to come from Eastern European University departments! :p

I use this to add firewall bans for every brute force attempt on SSH and ftp.
