It is important to note that versions 2.x and 3.x of SSH Secure Shell do not serve as replacements for the SSH1 protocol. Rather, they rely upon an existing installation of Secure Shell 1.x to handle SSH1 connections. Thus, installing a version 2.x or 3.x server does not obviate the need to maintain installations of Secure Shell 1.x.
