Where to turn SSHv1 protocol and SSHv2 protocol on and off
On Red Hat Linux Enterprise version 3, I see in the /etc/ssh directory, the file sshd_config which has entries for SSHv1 and SSHv2 protocol. Howevr, majority of the entries are commented out. SSHv1 and SSHv2 are enabled since I can ssh to the remote ssh server host.
Where do I turn SSHv1 or SSHv2 on and off?
