Sorry for the late posting, but I've just reched this newsgroup.
But now to business.

I have encountered the same problem when trying to create a server process,
on another machine via 'system("rsh ....")'.  What I did, after consulting
with the local wizard was:

1. close fds 0, 1 and 2.
2. fork() - the server runs as the child process.
3. the father commits suicide.

This works just fine for me, but I guess it slows down the initialization.

Later, the initiating process on machine A, and the server process on machine
B talked using a socket.

Try it, and may god be with you.
