Yeah, it fact it sounds like most rootkits I've seen.

Sure, some kits deploy a sniffer in one place, sshd in another, adore
(have you found anyth kernel-level?) in yet another place.

It can be one  or it can be more. If you had no Tripwire/integrity
checking software there is no way to _reliably_ find all traces of the
penetreation. In fact, even if you do have it - it is still not likely.
Rebuilding the box is the most popular advice given in this list ;-)
