Stock 2.2.6-STABLE

>Description:

When someone logs in from a host with a valid PTR record, but not a valid A
record, only "invalid hostname" gets logged.  It is then impossible to tell
where the person logged in from.  Great implementation decision, there.
E.g.:

kithrup 1% w
 8:32PM  up 14 days,  5:53, 7 users, load averages: 0.06, 0.09, 0.03
USER     TTY FROM              LOGIN@  IDLE WHAT
mumble  p2  invalid hostname  8:15PM    10 -csh

kithrup 2% last -1 mumble
mumble  ttyp2    invalid hostname Sun Mar 14 20:15   still logged in

>How-To-Repeat:

See above.

>Fix:
	
Replace the entire system and go back to the original CSRG method; at least it
didn't give "invalid hostname" as the only indication of where the host came
from.
