sshguard
Sshguard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication.

Changes: This release fixes compilation issues on Solaris, fixes the "hosts" backend's logic for temporary files, and fixes the blacklist module to avoid inconsistencies in saved blacklists.
- 02 Mar 2010 13:28
Changes: With respect to 1.5beta3, this release completes support for IPv6 by adding support for CIDR-based IPv6 whitelisting and whitelisting of both IPv4 and IPv6 addresses when adding hosts. IPv4-mapped IPv6 addresses are passed to backend firewalls as IPv4. This is the last release that adds features for 1.5. The next releases will only fix bugs until 1.5 stable.

Changes: Sshguard now recognizes "last message repeated N times" messages, contextually and per-source. Attackers are now gauged with dangerousness instead of attack counts by adjusting the '-a' option. Support for Sendmail relaying abuse and for vsftpd authentication failure messages has been added. The recognition of messages of Gentoo's PAM implementation for authentication failure has been added.
