Please find the diffs for an updated port of sshguard attached. This updates sshguard from version 1.5 to 2.1.0. One of the main reasons to update to this version is that sshguard now seems to correctly parse the OpenBSD sshd logs. One can now also block an entire subnet rather than individual IP addresses, if one is so inclined.
I have been running this port for a few weeks, and it seems to work as advertised. Note that the /etc/sshguard.conf file now is required (I modified the sample file so that it hopefully fits a vanilla OpenBSD system). I posted about this update in late March when I had issues getting the sshguard service to properly shut down, but that issue has since been resolved (rc_stop() needs to send it the HUP signal).
