A Graphical Network Monitor
EtherApe is a graphical network monitor for Unix, modeled after etherman. Featuring link layer, IP, and TCP modes, it displays network activity graphically. Hosts and links change in size with traffic. Various protocols are color coded in the display. It supports ethernet, FDDI, token ring, ISDN, PPP, and SLIP devices. It can filter traffic to show and can read traffic from a file as well as live from the network.
