Symptom: The rpcbind process on the TED opens ports within the IANA well-known port range (0-1023). This is in addition to the expected standard 111 rpcbind port. For security and network security appliance management purposes the rpcbind process on the TED should not have the wrong protocols running on well-known ports. Reproduce: lsof +M -P | grep rpcbind | grep -v 111 | grep \: Observe that the rpcbind process has ports open within the IANA well-known port range (0-1023). Example: rpcbind 1931 rpc 7u IPv4 14164 0t0 UDP *:834 rpcbind 1931 rpc 10u IPv6 14169 0t0 UDP *:834 Conditions: Fully configured and operational TED.
