How to change the port of your ssh server!

To switch for example the ssh port to port 1468, you should replace as follow :

# What ports, IPs and protocols we listen for
Port 1468

For the choice of port, use a port greater than 1024.

3- Restart your ssh server :

# /etc/init.d/sshd restart

4- Verify that your ssh server started using the right port :

# netstat -nptl | grep 1468

tcp       0      0 0.0.0.0:1468               0.0.0.0:*                    LISTEN     3986/sshd
