MTR Network Diagnostic Tool

MTR (My Traceroute) is a free and open-source network diagnostic tool that combines traceroute and ping into a single real-time interface. Originally created by Matt Kimball in 1997 (later maintained by Roger Wolff), it is one of the most widely used network troubleshooting tools for system administrators and network engineers. The tool continuously probes the network path between the local host and a destination, showing hop-by-hop latency and packet loss statistics in real-time. Key features: combined traceroute and ping: while traceroute discovers the network path (routers between source and destination) and ping measures latency, this tool does both simultaneously and continuously. Each intermediate router is discovered via ICMP TTL expiry, then each hop is pinged repeatedly to build statistics. Real-time display: a curses-based interface showing hop number, hostname, IP address, packet loss percentage, sent and received counts, and latency statistics (last, average, best, worst, standard deviation). The display updates continuously. TCP and UDP modes: in addition to ICMP probes, supports TCP SYN probes (--tcp) and UDP probes (--udp) for environments where ICMP is blocked. AS lookup: display the AS number for each hop (--aslookup) to identify the network provider. JSON and CSV output: generate machine-readable reports for monitoring systems and scripts. Report mode: run a fixed number of cycles and produce a summary report for ticketing systems. Configurable ping interval, probe count, packet size, TTL range, and port. Cross-platform: Linux, macOS, BSD, and Windows (via WinMTR). C. GPL-2.0.
