Description Jim.Pirzyk 2001-01-26 20:40:01 UTC 
	in the realhostname_sa routine (libutil), if the hostname of the remote
	system is > 16 characters long, the IP number is stored in the wtmp
	file.  This happens even for hosts that are in the same DNS Domain.
	Conversely, in the login program, which does not call realhostname_sa,
	it trims the hostname before writing the hostname into the file.
	realhostname_sa is called by sshd.

How-To-Repeat: 
	Login to a remote FreeBSD host from a host that has a long hostname.
	First login with rsh, then do a finger -sh, it should show a short
	hostname for 'Where'.  Then login via ssh, do the finger -sh and it
	will show the IP number instead.
