When I do an rpcinfo -p, I find: program vers proto port 100026 1 udp 750 bootparam But port 750 is the port reserved for kerberos in /etc/services: kerberos 750/udp kdc # Kerberos authenticat ion--udp You're running afoul of Sun's portmapper. You have to fire up Kerberos first. For that matter, if you kill and restart bootparam, I think you'd get a different port. I forget exactly what range the portmapper will use; the real would have been to use a port number not in that range for Kerberos. Perhaps for V5?
