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 ...
The following tables compare general and technical information for several packet analyzer software utilities, also known as network analyzers or packet sniffers. Please see the individual products' articles for further information.
The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and macOS. The client can also run on Microsoft Windows, although, aside from external drones (see below), there's only one supported wireless hardware available as packet source. Distributed under the GNU General Public License, [2] Kismet is free software.
netsniff-ng is a free Linux network analyzer and networking toolkit originally written by Daniel Borkmann. Its gain of performance is reached by zero-copy mechanisms for network packets (RX_RING, TX_RING), [3] so that the Linux kernel does not need to copy packets from kernel space to user space via system calls such as recvmsg().
ngrep, aka "network grep", isolate strings in packets, show packet data in human-friendly output. Nmap, a port-scanning and fingerprinting network utility; Pirni, a discontinued network security tool for jailbroken iOS devices. Scapy, a packet manipulation tool for computer networks, written in Python by Philippe Biondi.
tcpdump prints the contents of network packets. It can read packets from a network interface card or from a previously created saved packet file. tcpdump can write packets to standard output or a file. It is also possible to use tcpdump for the specific purpose of intercepting and displaying the communications of another user or computer.
The Chinese government uses deep packet inspection to monitor and censor network traffic and content that it claims is harmful to Chinese citizens or state interests. This material includes pornography, information on religion, and political dissent. [25] Chinese network ISPs use DPI to see if there is any sensitive keyword going through their ...
