Rcp (Unix)

From Wikipedia, the free encyclopedia

rcp is a command on the Unix operating systems that is used to remotely copy -- to copy one or more files from one computer system to another. It typically uses the TCP/IP protocol and the .rhosts file for authentication, but has been implemented to alternatively support Kerberos.

As described in the rlogin article, the rcp protocol is not secure for network use, because it sends unencrypted information over the network, among other things. It has largely been replaced by the ssh-based utility scp.
