VoIP monitor
VoIP SIP and SKINNY quality analyzer and packet / audio recording tool
VoIPmonitor is open source network packet sniffer with commercial frontend for SIP SKINNY MGCP RTP and RTCP VoIP protocols running on linux. VoIPmonitor is designed to analyze quality of VoIP call based on network parameters - delay variation and packet loss according to ITU-T G.107 E-model which predicts quality on MOS scale. Calls with all relevant statistics are saved to MySQL or ODBC database. Optionally each call can be saved to pcap file with either only SIP / SKINNY protocol or SIP/RTP/RTCP/T.38/udptl protocols. VoIPmonitor can also decode audio. -

NetStalker
A network tool to control the bandwidth over your local network
A network tool to control the bandwidth over your local network, it can block internet access from any selected device, or limit its speed using packet redirection, in addition, it can log web activity for the targeted device using a built-in packet sniffer. Bandwidth limitation for better distribution of internet speed across devices, both upload and download speeds can be controlled for each device separately. A Packet Sniffer that is intended to log addresses that each device on the network visits with the ability to decode Http headers for HTTP packets and resolve domains for HTTPS packets, also the packet direction can be chosen in order to capture requests only or requests and responses. -

Scapy
Scapy is a Python-based interactive packet manipulation program
Scapy is a powerful Python-based interactive packet manipulation program and library. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, store or read them using pcap files, match requests and replies, and much more. It is designed to allow fast packet prototyping by using default values that work. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, wireshark, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining techniques (VLAN hopping+ARP cache poisoning, VoIP decoding on WEP protected channel, ...), etc. Scapy supports Python 2.7 and Python 3 (3.4 to 3.7). It's intended to be cross platform, and runs on many different platforms (Linux, OSX, *BSD, and Window -

Arkime
A full packet capturing, indexing, and database system
Arkime is an open source, large-scale, full packet capturing, indexing, and database system designed to augment existing security infrastructure by storing and indexing network traffic in standard PCAP format. It offers full network visibility, facilitating the swift identification and resolution of security and network issues. Security teams gain access to the necessary network visibility data essential for responding to and investigating incidents to expose the full attack scope. Designed to be deployed across multiple clustered systems, Arkime provides the ability to scale to hundreds of gigabits per second. It allows security analysts to respond, reconstruct, investigate, and confirm information about the threats within your network, enabling appropriate responses quickly and precisely. As an open-source platform, Arkime provides users with the benefits of transparency, cost-effectiveness, flexibility, and community support. -

netsniff-ng
A Swiss army knife for your daily Linux network plumbing
netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa. Our toolkit can be used for network development and analysis, debugging, auditing, or network reconnaissance. -

Xplico
Xplico is a Network Forensic Analysis Tool (NFAT)
Xplico is a Network Forensic Analysis Tool (NFAT). The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP, MGCP, MEGACO, RTP), IRC, WhatsApp... Xplico is able to classify more than 140 (application) protocols. Xplico cam be used as sniffer-decoder if used in "live mode" or in conjunction with netsniff-ng. Xplico is used also in CapAnalysis: http://www.capanalysis.net -

Shadow Network Fingerprinting Engine
SNF is a 100% offline, air-gap passive network intelligence engine
# SNF — Shadow Network Fingerprinting Engine 100% offline. Air-gap-native. Written entirely in Rust. SNF captures raw packets, reconstructs TCP/UDP flows, and runs them through 14 deterministic protocol analyzers. It detects C2 beacons, DGA domains, DNS tunnels, lateral movement, data exfiltration, and full ICS/SCADA protocol abuse across Modbus, S7comm, EtherNet/IP, PROFINET, and DNP3. Every run produces structured NDJSON with a determinism guarantee — same PCAP, same config, same version, SHA-256 identical output every time. Court-admissible evidence bundles built in. **Zero network calls. Ever. Not a setting. Architecture.** ## Validated Results - Emotet epoch 3 PCAP — 23 IOC hits, 52 threat matches - MAWI backbone — 14.9M packets, zero crashes, 332K graph nodes - nmap standard scan — 1,971 scan events detected ## Links - Website: https://shadownf.com - GitHub (open core): https://github.com/padigeltejas/snf-core -
