Console server probes from outside

My console server is TCP wrappered (duh) and I've noticed several of
these in the past couple of days (all from the same host):

  conserver attempt from H-135-104-26-223.research.bell-labs.com

I don't know if it's just a port scan or if they are probing a potential
console server security hole.

Not to start a panic.  Just a head's up in case something bad is floating
around out there.

Sigh.
