Yes and no. > (Yes I enabled RPC Control in Policy -> Properties ...) rsh is not an RPC service. This is has no bearing on the issue. Like FTP and other protocols from hell, rsh uses a secondary connection going from the server back to the client. In the rsh case, it is set up to carry stderr. IIRC, Check Point 4.1 has a "Property" about enabling this "RSH/REXEC stderr" connection. Make sure this is enabled. If it is not, then one would expect to see the problems you are having. -- Crist J.
