How to change default SSH port on Linux

Changing the default SSH port from the default 22 is one of the things you should do to secure your server.

The main benefit of changing the default port is to avoid being scanned by casual port scans.

Changing the default port to a random number get rid of some dangerous brute-force attacks.

  1. Login Via SSH

First you need to log in to your VPS via SSH. If the default port is 22 then you will not need to specify the port.

ssh root@IP_Address
  1. Update Packages

For CentOS

yum update -y

For Ubuntu

apt-get update $$ apt-get upgrade
  1. Open SSH Config File

Once the packages are updated, open the SSH configuration file with your favourite editor and find the line that specifies the SSH port

vim /etc/ssh/sshd_config
#Port 22
  1. Change port number

Uncomment the line by removing the # sign and change the default port 22 to one that you want to use.

Port 9845

Save changes and exit


Before changing the port, you should make sure that the new port is free and not used by any other service on your VPS.

You should also check that the port is not closed by your server’s firewall

  1. Restart SSH Service

For the changes to take effect, the service needs to be restarted

service sshd restart
  1. Check SSH port

Once restarted, SSH will listen on port 9845 .

This can be checked by running the following command

netstat -tunlp |grep ssh
