SSH Port Configuration - Setting Higher Port Numbers
I've been having some grief with ssh. If I leave it set to run with defaults - i.e. at port 22 I have no issues. I am running behind a zyxel adsl modem/router and have NAT set to keep 22 open, and ssh set as an available service in the suse firewall. I have wanted to get ssh running on a different port with the hope that perhaps attempts at logins by script kiddies will be minimised. However when I set /etc/ssh/ssh_config to run at port 57921, set NAT on my router to forward this port and restart the sshd daemon I get the error "SSH: Connection refused on Port 57921".
Am I missing something obvious here? I'd feel much better if I could get this running on a higher, less obvious port number. Any documentation I can find on ports seems to be relating to portforwarding and not reconfiguring existing ports. Any help appreciated.
