About:
Jnettop is a network traffic visualizer that captures packets from a specified interface and displays bandwidth usage in a top-like interface. It aggregates traffic by host and port, allowing users to identify the most active connections in real-time. This tool is essential for diagnosing network congestion and monitoring bandwidth hogs.
Key Features:
  • Real-time traffic visualization
  • Breakdown by host and port
  • ncurses-based interface
  • BPF filter support
Use Cases:
  • Diagnosing sudden network slowdowns
  • Identifying bandwidth-heavy applications
  • Monitoring live network connections
Alternatives:
  • iftop – iftop is a more common alternative that focuses on connection pairs, whereas Jnettop offers a distinct view grouping by service.
  • nethogs – nethogs groups bandwidth usage by process ID, while Jnettop groups by network host and port.
