Disable telnet in favor of passwordless SSH
This enables passworldless login for root via SSH whenever no root password is set (e.g. after reset, flashing without keeping config or in failsafe) and removes telnet support alltogether. Signed-off-by: Steven Barth <steven@midlink.org> SVN-Revision: 46809
