I think what you need is an entry in root's .rhosts file on the server
machine. Login as root on the server and add my.pc to the .rhosts file
in root's home directory. If the file doesn't exist, create it. Make
sure you chmod 0600 so others cannot change the file.
You may want to do the converse on my.pc to allow the root user on the
server to be equivalent to root on my.pc. An alternate way to transfer
the files to the server while logged in as root on the server is:
cd <target_directory_on_server>
rsh my.pc "cd /usr; tar cf - ." | tar xf -
--Bob
