 Plain vanilla standard FreeBSD install (6.3-RELEASE and 7.0-RELEASE). 
 There is no more context, the system logs only a single line:
 
 Sep  5 17:06:17 server sshd[71127]: error: PAM: authentication error for 
 xyz from 10.1.1.1
 
 This is basically what sshguard 1.0 was looking for.
 What's your uname -a?
 
 Also, by the way, because there is only one line of log, as a bonus 
 syslogd agregates the error messages (last line repeated n times) which 
 is something sshguard also doesn't handle.
