EchoTool - Echo client and server

Heavily inspired by EchoTool.

Command line echo server and client. This tool is designed according to RFC 862 specification for Echo protocol. It can operate as an echo server that sends back every incoming data. In client mode, it sends data to the server and checks whether they came back. This is a useful debugging tool for application development or network throughput checks.

• Server mode
• Client mode
• TCP and UDP protocol support
• Selectable destination and source port
• Selectable timeout
• Selectable echo pattern
• Just one file
