Use NetHogs in CentOS6.5 to monitor network usage of processes

Nethogs is a network traffic monitoring tool on a terminal. It displays the bandwidth usage of each process, so that the network usage can be obtained more intuitively. It supports IPv4 and IPv6 protocols, local NICs, and PPP connections.
