I've been researching sshd and allowing/denying access and I think I have figured it out. Just please confirm that I'm on the right track.
I edited my hosts.allow as follows:
# # hosts.allow This file describes the names of the hosts which are # allowed to use the local INET services, as decided # by the '/usr/sbin/tcpd' server. # sshd: localhost 192.168.0.0/255.255.255.0 12.30.163.*
And then my hosts.deny as follows:
# # hosts.deny This file describes the names of the hosts which are # *not* allowed to use the local INET services, as decided # by the '/usr/sbin/tcpd' server. # # The portmap line is redundant, but it is left to remind you that # the new secure portmap uses hosts.deny and hosts.allow. In particular # you should know that NFS uses portmap! ALL : ALL
However, I don't really have anyway to test this as I allowed access from everywhere that I am. :)
Any suggestions and advice is still greatly appreciated.
