Netcat can be used as a simple data transfer agent, and it doesn't really

matter which end is the listener and which end is the client -- input at one

side arrives at the other side as output.  It is helpful to start the listener

at the receiving side with no timeout specified, and then give the sending side

a small timeout.  That way the listener stays listening until you contact it,

and after data stops flowing the client will time out, shut down, and take the

listener with it.  Unless the intervening network is fraught with problems,

this should be completely reliable, and you can always increase the timeout.  A

typical example of something "rsh" is often used for: on one side,



        nc -l -p 1234 | uncompress -c | tar xvfp -



and then on the other side



        tar cfp - /some/dir | compress -c | nc -w 3 othermachine 1234



will transfer the contents of a directory from one machine to another, without

having to worry about .rhosts files, user accounts, or inetd configurations

at either end.
