Set SSH protocol to 2

Set SSH protocol to 2

SSH has two protocols it may use, protocol 1 and protocol 2. The older protocol 1 is less secure and should be disabled unless you know that you specifically require it.

  1. Open the sshd config
    vi /etc/ssh/sshd_config

  2. Add or amend as shown below
    # Protocol 2,1
    Protocol 2

  3. Restart the sshd service
    systemctl restart sshd.service
