With the command "netstat -an | grep LISTEN",
I can see the following:
.....
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:25              0.0.0.0:*               LISTEN  
......
tcp6       0      0 :::22                   :::*                    LISTEN     
tcp6       0      0 :::25                   :::*                    LISTEN
