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.
