How to Install And Use Graphical Network Monitor Etherape On Ubuntu Linux 16

EtherApe is a packet sniffer/network traffic monitoring tool, developed for Unix/Linux modeled after etherman. EtherApe is free, open source software developed under the GNU General Public License. It displays network activity graphically. Hosts and links change in size with traffic and displays color coded protocols. It supports Ethernet, FDDI, Token Ring, ISDN, PPP, SLIP and WLAN devices, plus several encapsulation formats. It can filter traffic to be shown, and can read packets from a file as well as live from the network.
