Does anyone know how to restrict ssh login access to certain ip's??
e.g. like host.allow does? I have found un-authorised attempts trying
to log in via ssh in var/logs/secure...

In /etc/ssh/sshd_config, I have:
PermitRootLogin = no
ReverseMappingCheck = no
# I can not use this as our ADSL ip address does not reverse map
# though I am investigating this.
