nc, TCP/IP swiss army knife, is an utility to transfer data across the network (actually is much more then that...). If you need to transfer large files inside you private network it might be a good idea to use nc, instead of heavier data transfer protocols (such as nfs, samba, ssh, http...)

Server side :

nc -vvn -l -p 3000 -w 3 | pv -b > outputfile


where -l says to listen and -p 3000 specifies the port.

Client side :


nc -vvn 192.168.0.5 3000 < inputfile


This is pretty straightforward.

To make the process a bit more human friendly I've used pv that is a small monitor the progress to show how much data has been transfered.
