Are you using daemon-mode over rsh/ssh?  If so, the only way rsync has
to discover the remote IP address is out of the environment.  It tries
SSH_CONNECTION, SSH_CLIENT, and SSH2_CLIENT (all of which are, of
course, entirely insecure since they could be overridden by the user
prior to running rsync -- your remote shell is is the thing providing
the security in such a scenario, not rsync).

If you're using an rsync daemon via sockets, you should investigate why
client_sockaddr() isn't functioning properly.
