Can I change the port ssh listens on?

Support Portal  »  Knowledgebase  »  Viewing Article

Yes you can change the port that SSH listens to by editing the /etc/ssh/sshd_config file and uncommenting (Remove the # from the beginning the line) the line containing below.

#Port 22

Example of a changed SSH port

Port 55555

You then can change the number to a uncommon SSH port. Some good examples are 5555 or 33333. You will then have to open that port on in the APF configuration file located at /etc/apf/conf.apf.

You will want to add this new port number to the lines below.

# Common ingress (inbound) TCP ports


# Common egress (outbound) TCP ports

After saving the conf.apf file you will need to restart both APF and sshd by issuing the command below on the command line.

/etc/init.d/apf restart && /etc/init.d/sshd restart
