Are you sure there are no firewalls in place that could be blocking access? Note that "rsh machine" really calls "rlogin machine" and so talks on a different port (port 513) whereas "rsh machine command" uses port 514.

You should tcpdump the traffic while trying to do an rsh to see what is going on.

I figure you've probably checked this already, but is rcpwrappers installed? If so, are hosts.deny and hosts.allow setup good? I suspect so - I think I saw you had some kind of successful connect earlier in the thread.

Have you run with the -d parameter?
