Select SSH

I'd like to turn off ssh except for the one other computer I use. Is there a good way to do this and would it make it any more secure?

 

You can add an iptable rule to deny destination port 22 to all machines except the IPs you want to enable. Be sure you can access the console in case you screw up

Thanks, but I'm not sure how to do that. Sorry, but can you walk me through it?

 

I'm not such an iptables expert, so you'd better take a look at

Another easier way is suggested, using /etc/host.allow and /etc/host.deny
