udp-echost is a single-binary UDP diagnostic tool for Linux. It runs as a client/server pair: the server echoes packets back, and the client times the round trip to report RTT, jitter (RFC 3550 style), packet loss, reordering, and P50/P95/P99 latency percentiles.
Unlike ping (ICMP-only) or iperf (throughput-focused), udp-echost measures actual UDP round-trip latency distribution for a payload size you choose, which matters for diagnosing UDP-specific applications (VoIP, gaming, custom protocols) where ICMP behavior on the path doesn't match UDP behavior.
Usage: Server: udp-echost -s -p 50505 Client: udp-echost -c <host> -p 50505 [-n count | -t seconds | --continuous]
Run udp-echost --help for the full flag reference.
