I had the same 'problem'. As said it's not realy a problem since FreeBSD will hold just fine if you don't have any rather stupid user + pass combinations. ( test test or something like that ) Allthough I thought it was annoying that my intire log was clouded with those brute force attacks so I just set sshd to listen at an other port then 22. Maybe that's a acceptable solusion for you ? You can change the ssd port in /etc/ssh/sshd_configI recently installed FreeBSD 6.1 on my gateway. It replaced an installation of FreeBSD 4.6.8 (fresh install, not an upgrade) on which I had disabled the SSH server. Since all the bugs in SSH are fixed now ( :-) ), I thought I'd leave the server on, and am somewhat dismayed to discover that I now get occasional brute-force/dictionary attacks on the port.A little Googling revealed a couple of potentially useful tools: 'sshit' and 'bruteblock', both of which notice repeated login attempts from a given IP address and blackhole it in the firewall. I first tried 'sshit', but after a couple days, I noticed in my daily reports that I was still getting lengthy bruteforce attempts, suggesting the 'sshit' was not working. So I uninstalled 'sshit' and installed 'bruteblock'. But again a couple days later, the logs showed lengthy bruteforce attempts going unblocked. The relevant lines from my /etc/syslog.conf file are: ---- auth.info;authpriv.info /var/log/auth.log auth.info;authpriv.info | exec /usr/local/sbin/bruteblock -f /usr/local/etc/bruteblock/ssh.conf ---- Any hints as to what I might be doing wrong?
