Changed SSH port still running on port 22

Hey all, I'm trying to change my ssh port from 22 to something much higher and not having much luck. I changed the port designation in /etc/services

jobee@vmDeb6:~$ grep ssh /etc/services
# ssh-Moved     22/tcp                          # SSH Remote Login Protocol
# ssh-Moved     22/udp
ssh             13247/tcp                       # SSH Remote Login Protocol
ssh             13247/udp
and then ran

/etc/init.d/ssh restart
but I still can only connect ssh to port 22. I even rebooted my server and still no joy. Are there any additional steps that I missed???

The purpose of /etc/services is not to configure which ports things run on, it is simply a reference document that lists standard port numbers.

If you want to change the port a service runs on, you need to adjust that service's configuration file. In the case of SSH, it would be under /etc/sshd.

Thanks MS3FGX, I found it. It was actually under /etc/ssh but your instructions helped me find it. FWIW (and for anyone else looking for this information) the changes need to be made in sshd_config.

Thanks again,

Joe B
