This supports privileged and unprivileged commands, as well as a configuration mode * Add help for all cli commands * Add "show version" command * Fix uptime counter display * Fix nasty bug where cluster basetime can be set to 0 when sending initial heartbeat * Don't rmmod ip_conntrack, as this can take a lot of time * Re-order logging in routeset such that the action is given before any error * Use the correct gateway address when deleting routes * Remove any routes when address changes * Require authentication if telnet from remote ip * Require enable password always * Return error if show pool done on slave * We MUST immediately exit if we're the wrong master!
