How can I change the port ssh listens on? | The Planet Knowledge Base

You can edit sshd_config to change the port sshd listens on. The default directory for ssh configuration is /etc/ssh.

Backup the current configuration and use your favorite editor to change the Port line:

root@root [~]# cd /etc/ssh/

root@root [/etc/ssh]# cp sshd_config sshd_config.save

root@root [/etc/ssh]# vi sshd_config

#Port 22

I will set mine to port 4000. Do not forget to remove the comment (#).

Port 4000

root@root [/etc/ssh]# diff sshd_config sshd_config.save

13c13

< Port 4000

—-

> #Port 22

root@root [/etc/ssh]#

Restart sshd and verify that it is listening on the new port.

root@root [/etc/ssh]# /etc/init.d/sshd restart
