When a UNIX system tries to Remote Copy (RCP) or Remote Execute (REXEC) with a Windows NT system, the connection is refused. If you run the command GUEST@OLYMPUS 7 :/USR/GUEST>RCP TEST INDURAIN:TEST from SCO UNIX, the following error message is generated:

rcmd: connect: Connection refused

A similar error message is returned for REXEC. In addition, if you enter a local host name and a local user name using RCP (see example below), a similar error message appears. The local host name and the local user names are not required.

Example of RCP Command:

rcp <localhost>.<localuser>:<filename>



rcp <remotehost>.<remoteuser>:<filename>



Windows NT does not have the server portion of the Remote Copy and Remote Execute commands (usually, rshd and rexecd, respectively); therefore, the connection is refused.


This behavior is by design.

Additional query words: prodnt tcp/ip rcp rexec rshd rexecd
