A real-timish network traffic monitoring tool that uses a web interface with charts.

Figure 1. Occurrences and endpoints of IPv4 addresses.

Figure 2. Protocol hierarchy statistics listing both number of packets and bytes.

Server

tcpdump writer

php cli/tcpdump-writer.php eth0 $USER

tcpdump-writer.php sniffs the network traffic and stores the resulting .pcap files in the var/tmp folder for statistical analysis with tshark.

This is how to set up tcpdump in order to capture packets as a non-root user:

sudo groupadd pcap
sudo usermod -a -G pcap $USER

sudo chgrp pcap /usr/sbin/tcpdump
sudo chmod 750 /usr/sbin/tcpdump

sudo setcap cap_net_raw,cap_net_admin=eip /usr/sbin/tcpdump

WebSocket server

php cli/ws-server.php

Client
