Network Interface Monitor

A real-time network interface throughput, IPv4/IPv6 addressing, TCP/UDP/IP/ICMP protocol counter, and kernel routing table monitor for Linux.
A lightweight Linux alternative to NirSoft AdapterWatch for viewing live network adapter activity, packet statistics, and routing configuration.

Key features:
- Monitors live network interfaces from /proc/net/dev and /sys/class/net/* including operational state, MAC address, IPv4/IPv6 addresses, MTU, link speed, cumulative and session-delta RX/TX bytes, packets, errors, and drops.
- Renders a real-time dual-series RX and TX throughput history chart with configurable polling intervals (500 ms to 5 s) and one-click session baseline reset.
- Displays live kernel TCP, UDP, IP, ICMP, and socket statistics from /proc/net/snmp, /proc/net/netstat, and /proc/net/sockstat with search filtering and session delta tracking.
- Decodes IPv4 (/proc/net/route) and IPv6 (/proc/net/ipv6_route) kernel routing tables into human-readable CIDR destinations, gateways, flags, and metrics, with one-click JSON and CSV telemetry export.
