Publisher review:sshdfilter blocks the frequent brute force attacks on ssh daemons. sshdfilter blocks the frequent brute force attacks on ssh daemons.
It does this by directly reading the sshd logging output (or syslog output) and generating iptables (or ipfw) rules, the process can be quick enough to block an attack before they get a chance to enter any password at all.
The blocking policy is defined by a list of blockrules largely by user name or by the type of user name. There are two install routes, the old style sshdfilter starts sshd itself, having started sshd with the -e and -D options.
