One NIS client can't resolve host names

I am trying to setup NIS on a 3-node network:
* giraffe: NIS server running ubuntu 7.10 server
* owl: client runing 7.10 ubuntu desktop
* wolf: client running 8.04 ubuntu desktop

Symptoms:
* when I restart wolf, NIS won't resolve names until i restart ypbind; not an issue on owl
* after ypbind is restart on wolf, yptest still fails one of the tests:
Test 2: ypbind
Can't communicate with ypbind
owl fails the same way
* I restart the server with debug turned on (ypserv -d) and run yptest from the client I see some odd errors:
ypproc_match(): [From: 192.168.0.92:50307]
            domainname = "quince.nis"
            mapname = "hosts.byaddr"
            keydat = "192.168.0.90"
connect from 192.168.0.92
      ypdb_open("quince.nis", "hosts.byaddr")
Found: quince.nis/hosts.byaddr (2)
ypdb_close() called
      -> Error #-3

            keydat = "nobody"

one more oddity:
* ping resolves the name but ssh does not
bill@wolf:~$ ssh giraffe
ssh: connect to host giraffe port 22: Connection refused
PING giraffe.xxxxx.com (127.0.1.1) 56(84) bytes of data.
64 bytes from wolf.xxxxx.com (127.0.1.1): icmp_seq=1 ttl=64 time=0.197 ms

ssh *does* resolve giraffe, but giraffe refuses the connection. That is a different problem.

I rebuilt my nis db and it made no difference. on the other hand, putting ypbind in the rc.local does work. But why should it?

do you know what the problem might be? do i have to file it as a separate case?

Check IPTABLES settings on giraffe. Only file separate Q if problem remains unresolved after you're satisfied with NIS answer(s)
