Solaris: using nc to transfer file


The example in the previous section can be expanded to build a basic data transfermodel. Any information input into one end of the connection will be output to the other end,and input and output can be easily captured in order to emulate file transfer.
     Start by using nc to listen on a specific port, with output captured into
     a file:

           $ nc -l 1234 > filename.out

     Using a second machine, connect to the listening nc process, feeding it
     the file which is to be transferred:

           $ nc 1234 <

     After the file has been transferred, the connection will close automati-
