If you do not have SELinux or firewalld, skip to the last step before the end of the tutorial. If you have a firewall running, you also must continue with the following.

There are some additional steps you must take if you have SELinux, a Linux kernel security module also known as Security-Enhanced Linux, enabled on your server. To bring your changes into effect, you must restart the SSH daemon. If you have difficulty choosing a new port number however, you can look up what common ports are used online through lists of well-known TCP and UDP port numbers that are available, and choose one that is not listed.Īfter writing your new port in the configuration file, save and close the file.

Generally, it is recommended to use a new port number that is over 1024. Also stay away from ports that are already in use by your CentOS 7 server. When choosing a new port number, try to avoid using a common port from this list: 21, 80, 443, 25, 110, 113. In our example, we will use port 2222 so our line in the sshd configuration file will look as follows: If the line contains the “#” symbol, meaning that the line is commented out and thus is ignored, remove this symbol and change the port number from 22, which is the default SSH port, to your desired port. Search the file for a line that appears as either #Port 22 or Port 22.

The %F ensures that the full date in year-month-date format is used when obtaining the current date with date.Ĭp -p /etc/ssh/sshd_config /etc/ssh/sshd_config.orig.$(date +%F) Use the copy command cp with the flag -p, which preserves last edited information, to make a copy of the file and save it in a backup file whose name includes the date, which is achieved by appending the result of $(date +%F) to the filename. Before we do this step however, we will create a backup of the existing sshd configuration file as a matter of good practice. To change the SSH port of your server, you must edit the configuration file for the SSH daemon that is found in /etc/ssh/sshd_config.
