To change which port ssh listens on, you just need to edit the sshd_config file. The default directory for ssh configuration is /etc/ssh.
- First, backup the current configuration and use your favorite editor to change the Port line:
[email protected] [~]# cd /etc/ssh/
[email protected] [/etc/ssh]# cp sshd_config sshd_config.save
[email protected] [/etc/ssh]# vi sshd_config
- Now, locate the following line:
- For this example, we’ll set it to port 4000, by replacing “Port 22” with “Port 4000“. *Note: Do not forget to remove the comment (#).
- Lastly, restart sshd and verify that it is now listening on the new port.
[email protected] [/etc/ssh]# /etc/init.d/sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]
[email protected] [/etc/ssh]# netstat -anp | grep sshd
tcp 0 0 0.0.0.0:4000 0.0.0.0:*
And there you have it! You can set the port number to whichever port you prefer, but keep in ming that port numbers between 0 and 1,023 are reserved for existing system services. For this reason, you’re typically better off choosing a number above Port 1023.
