Tcpdump works on most Unix-like operating systems: Linux, Solaris, FreeBSD, DragonFly BSD, NetBSD, OpenBSD, OpenWrt, macOS, HP-UX 11i, and AIX. In those systems, tcpdump uses the libpcap library to capture packets. The port of tcpdump for Windows is called WinDump; it uses WinPcap, the Windows version of libpcap.
Screenshot of Wireshark network protocol analyzer. A packet analyzer (also packet sniffer or network analyzer) [1] [2] [3] [4] [5] [6] [7] [8] is a computer program ...
tcptrace is a free and open-source tool for analyzing TCP dump files. [1] [2] [3] It accepts as input files produced by packet-capture programs, including tcpdump, Wireshark, and snoop.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
ngrep (network grep) is a network packet analyzer written by Jordan Ritter.It has a command-line interface, and relies upon the pcap library and the GNU regex library.. ngrep supports Berkeley Packet Filter logic to select network sources or destinations or protocols, and also allows matching patterns or regular expressions in the data payload of packets using GNU grep syntax, showing packet ...
tcpdump, a tool for capturing and dumping packets for further analysis, and WinDump, the Windows port of tcpdump. Zeek, an intrusion detection system and network monitoring platform. URL Snooper, locate the URLs of audio and video files in order to allow recording them. WhatPulse, a statistical (input, network, uptime) measuring application.
tcpdump, a packet analyzer; Ngrep, a tool that can match regular expressions within the network packet payloads; netsniff-ng, a free Linux networking toolkit; Wireshark, a GUI based alternative to tcpdump; dsniff, a packet sniffer and set of traffic analysis tools
Linux includes a BPF JIT compiler which is disabled by default. Kernel-mode interpreters for that same virtual machine language are used in raw data link layer mechanisms in other operating systems, such as Tru64 Unix , and for socket filters in the Linux kernel and in the WinPcap and Npcap packet capture mechanism.
