What is the difference between the SSH and SSH2 protocols?

Note: This answer only applies to versions of gFTP <= 2.0.15 The SSH protocol uses sftp >= 0.7 from http://www.xbill.org/sftp. SSH2 uses the native file transfers found in the commercial SSH2 and in later versions of OpenSSH. The SSH2 protocol uses the sftp-server executable on the remote host and the SSH protocol uses the sftpserv executable. Note: Due to confusion, the origional SSH protocol was removed in gFTP 2.0.15. It is not shown in gFTP 2.0.14, but there is a config option called enable_old_ssh to enable this protocol.
