/usr/bin/rexec (rsh-0.17-2.2) on an i686 box fails to connect to the correct port - there seems to be a confusion over network and host ordering of the port number. Adding a call to ntohs on the port parameter of the rexec(3) call fixes the problem. (This was a fresh installation of 7.0-respin on an i686 box)
