How to change the default ssh port number ?

[deadcaribou]

Hi !

I followed the standard debian way of doing this and changed the port number in /etc/ssh/sshd_config to 313
I verified that changes were correctly written in the file and turned the pi off and on again

On reboot, ssh hadn't change port and I had to go through the default port 22 to connect...

Any idea why changes in sshdconfig are not taken into account even after a cold boot ?
