Hi Sean, MAC address will not help you. But you can implenment many other ways to connect to your server. First you can change ssh port to listen different than 22, no mater which, I am hoping you know do this. Second you can implement iptables rule to accept all ssh connections to that port ... something like iptables -A INPUT -p tcp --dport 32022 -s any/0 -d your_server_ip -j ACCEPT Then implement rules to accept only 2 or more ( it depends on you ) ssh connection per minute, and you can make some rule for port knocking in combination with iptables ( I know port knocking is clear text, but posible intruder will get only ssh prompt ). Of course there are many other security considerations and I am hoping that other list member will take part in this discussion. I hope this helps Regards Elvir Kuric --- sean <seandarcy2@xxxxxxxxx> wrote: > I want to connect from travel to my server.
