The ssh_conf file is for outbound connections. We are not really bothered if protocol version 1 is used or not since it is up to the remote (receiving) server as to whether it accepts the connection or not. The sshd_conf file is used for inbound connections, and that we do want to check to ensure that SSH protocol version 1 is not allowed. In your case, from the RKH config file: ======= If the 'Protocol' option has not been set in the SSH configuration file, then a value of '2' may be set here in order to suppress a warning message. ======= So just set 'ALLOW_SSH_PROT_V1=2' in your RKH config file.
