SSHGuard aggregates system logs and blocks repeat offenders. +It can read log messages from standard input (suitable for piping from syslog) +or monitor one or more log files. Log messages are parsed, line-by-line, for +recognized patterns. If an attack, such as several login failures within a few +seconds, is detected, the offending IP is blocked. Offenders are unblocked after +a set interval, but can be semi-permanently banned using the blacklist option. + +IMPORTANT: +You will need to properly set up "sshguard" chain in iptables.
