>Environment:
FreeBSD 4.x
>Description:
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.

>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.
>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.
