[BBLISA] ypbind and ICMP host unreachable?

[Scott Ehrlich]

Brief refresher again -

RedHat Enterprise 5 server, CentOS 5 clients.  Test setup, everything works 
fine.  Production environment, clients cannot bind to yp on server.

In trying to track down the ypbind problem I'm having, I discovered tcpdump 
produces ICMP host <yp server> unreachable only when ypbind is run.

I'm doing some googling now to try and find an answer.

I'd be happy to entertain any feedback this list has, too.

Thanks.

Scott
