EtherApe is a graphical network monitoring tool for Unix and Unix-like operating systems. It is used for viewing network traffic visually. This means the more "talkative" a node is, the bigger its representation, and node and link colors show the most used protocol. While originally created as an etherman clone, it has since evolved to have some unique features. In addition to running as an active network capture tool, it can also read tcpdump capture files.
