Debug TCP, UDP and multicast links

A network debugging tool: open a TCP client, a TCP server, a UDP socket or a multicast group, then send and receive data by hand while watching the traffic in a log.

Features:

  • TCP client, TCP server with a client list, UDP and UDP multicast
  • HEX and text modes for both sending and receiving
  • Timestamps, sender addresses, pause, receive to file
  • Sending from a file with a progress bar, loop sending by interval
  • Sent and received byte counters
  • Changing the IPv4 address of a local network interface
  • Russian and English interface

The network engine is portable C11 with no Qt dependency, so the same code runs headless on embedded boards.
