Force the use of SSH protocol 2

Tuesday, 17 August 2004

SSH Protocol 1 based systems are facing many automated "root kits". As a result to step up the security Protcol 2 should be enabled as soon as possible. The reason to use SSH Protocol 2 on your dedicated webserver is that it is more secure. 1. Login to your dedicated server via SSH as root. 2. Type: pico -w /etc/ssh/sshd_config If pico is not installed and you receive an error Install PICO 3. Find the line: #Protocol 2, 1 Uncomment it and change it to look like: Protocol 2 4. CTRL+X then y then enter to save the file. 5. Now Restart SSH with Type: /etc/rc.d/init.d/sshd restart (If the above restart does not work you will need to login to WHM as root and restart the service.)
