Overview

The OpenSSH service for StorageLink is located on port 22 by default. However, some users may wish to move the OpenSSH service to that of a different port, which we will show how to do in this article.

Changing the SSH Port

First, SSH into your VM and elevate your privileges:

sudo su

Then, edit this file:

/etc/ssh/sshd_config

To change the ssh port you would modify this line:

Port 22

To a non-standard port such as port 2222 for example:

Port 2222

To apply your changes you would restart OpenSSH after modifying the config:

service sshd restart

Also, make sure the port you change to is allowed access in your firewall rules.
