If NICs present in following order, then, ypbind does not bind on
	fxp0, which has a default router associated. Ypbind always try to
	bind on a NIC up with lowest scopeid, but not the NIC had address
	associated with the default router.
	All other network services, such NFS, nslookup, work well, except
	ypbind.

Fix: 

Work around:

		Configure non primary NIC(s )(sk0 and sk1 in this case) in
	/usr/local/etc/rc.d/01.if-sk.sh if they come up at front of the primary
	NIC.
How-To-Repeat: 	Install at least two NICs, and user the second one as
	primary interface, and configure the system to use NIS.
	After system boot, issue command rcpinfo -p and/or ypwhich
	if you have a ypserv running.

	rcpinfo -p will hang forever.
	ifconfig the first NIC (sk0 and sk1 in this case) down and
	restart ypbind, then ypbind will work.
