Dhanesh, netcat is pretty much a general purpose networking tool. It can take stdin as input via using the pipe symbol at the command line, as well as pipe that input on the opposite end to stdout.
So as an extremely simple example: client side: $ nc -l -p 5000 > /path/to/somefile This will take input over the network from a local system attempting to connect to this system via netcat on port 5000. Then of course the command line redirection symbol, pipes whatever data comes in to a file. server side: $ cat /proc/cmdline | nc 192.168.7.2 5000 This pipes the ouput of a local system command( stdout ) to netcat, which in turns sends this data to a specified IP address, and port number. For me, I think one of the really interesting thoughts behind this process is that on the beaglebone side of things, the data could be kept entirely in memory by using / creating a tmpfs file . . . size can not be overly large of course. But I've personally used file sizes of 256M with no ill effects. As the applications i personally ran on this test system used less than 100M total for all processes. Anyway, just something to think about. Another thing I would like to mention, in case it's not obviously to you. Is that if your application can take stdin input like many std linux commands. You would be able to pipe recieved data from netcat directly to your application . . .
