Responses
On this test.com server, rpcbind (also known as portmapper) is running, and ypbind is running. That's OK.
But ypbind wants to connect first to your NIS server's portmapper to find out the port number of the ypserv process on the NIS server. This error message:
test.com ypbind-post-waitbind[14180]: rpcinfo: can't contact portmapper: RPC: Remote system error - Connection refused
seems to say ypbind cannot do that. So it is a problem connecting to the NIS server.
Go to your NIS server system, and run 'rpcinfo -p localhost' there. What does it say?
Check that rpcbind and ypserv processes are running on the NIS server host, and that firewalls are not blocking the NIS connections.
