Noux/net adds network functionality to noux. Currently most basic network related system calls including 'accept', 'bind', 'connect', 'listen', 'recv', 'send', 'shutdown', and 'socket' are implemented by wrapping lwip's network functions. At the moment noux/net is rarely usable, though it is possible to use netcat to send a message to a netcat server which listen on a given port in noux/net.
