>Description:
The BSD r-commands, rsh, rlogin ,etc, do not use the same IP address
for the outgoing connection for stderr as the local server when running
ona a host with address aliases.

To explain this with an example...
Server A has IP addresses 1.2.3.4 and 1.3.4.5
Client B does "rsh 1.3.4.5 who"
Server A accepts the connection on port 514 for 1.3.4.5 and initiates a
connection back to Client B using IP address 1.2.3.4.

The outgoing connection should use the same IP address as was made for
the incoming TCP connection.
