ypbind can't connect to ypserv on NIS master server

[Silas Silva <silasdb%gmail.com@localhost>]

Hello all.

I recently configured a box to run as a NIS master (NetBSD 4.0 xen3
domU) server in my LAN. I followed the how-to in this link:

http://wiki.netbsd.se/How_to_set_up_NFS_and_NIS

It worked well, clients could connect and users could login. Then, I
stopped services in the server to change some configuration. When I
restart then, I realized that ypbind couldn't connect to ypserv - it
stucked forever.

Here are the lines I have in rc.conf:

rpcbind=YES
ypserv=YES
ypbind=YES

(there is also yppasswd, but having it or not doesn't change this
strange behavior)

rpcbind and ypserv start ok, but ypbind doesn't. I need to Ctrl-C it.
The most strange thing is that, while ypbind looks for the server, I
can't ping (like ypbind, it also myself neither the external IP nor
localhost).

Also, clients start ypbind fine - they find ypserv and rpcbind running
on the server! Though, I cannot connect using users that was added in
the NIS master server: can't finish make in /var/yp because it complains
about not connecting to ypbind.

I did the `ypinit -m` configuration as that page described, set correct
domainname, started services and put them in rc.conf.

When querying about solutions to this problems, I found this thread:

http://mail-index.netbsd.org/netbsd-users/2007/12/13/0003.html

But this seems not to be related to my problem.

Any help? Thank you.
