TED-4.0.2.1

Description (partial)

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.
