How to Change SSH Port with WHM & CSF

If you are using WHM & CSF, under CentOS, you may follow this steps to change SSH port from 22 (default) to something else 🙂

  1. First we must allow incoming data in the new port. Open your WHM >> Plugins >> CSF.
  2. Click “Firewall Configuration” button.
  3. Add your new port in “TCP_IN” and “TCP_OUT”.
  4. Click “Change” button in the bottom of the page.
  5. You will be asked to restart CSF & LFD. Do it.
  6. Next, edit this file
    /etc/ssh/sshd_config

    You can use vi

    vi /etc/ssh/sshd_config
  7. Find this line
    #Port 22

    Change to your chosen port, and remove the comment ( # sign )

    Port 9999
  8. Restart the SSH service from WHM : Restart Services > SSH Server (OpenSSH), or with this command :
    service sshd reload
  9. It’s done 🙂
  10. Optional steps : remove port 22 from CSF > Firewall Configuration > TCP_IN & TCP_OUT
