Description Darern Reed freebsd_committer

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.

How-To-Repeat: 
use rsh from a client to a freebsd server with multiple addresses and
connect to an alias, noticing that the return connection does not
originate from the same source as the destination of the client.
