Symptom: The rpcbind process on the PCG 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 PCG 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 2189 rpc 7u IPv4 15460 0t0 UDP *:668 rpcbind 2189 rpc 10u IPv6 15467 0t0 UDP *:668 Conditions: Fully configured and operational PCG.
