[Sshguard-users] sshguard-1.5-r1 on gentoo: log entries missed

[Robert S <rob...@gm...>]

I have been getting a lot of these messages:

Mar 11 13:40:36 myhost sshd[30548]: User root from 202.111.128.225 not
allowed because none of user's groups are listed in AllowGroups

These are not triggering any response to sshguard.  I have the following
line in my /etc/ssh/sshd_config:

AllowGroups ssh_users

Is there some way that sshgurard can be got to respond to these?
Alternatively is it possible to activate the firewall after an attempted
root login?
