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().
On wired shared-medium networks, such as Ethernet, Token Ring, and FDDI, depending on the network structure (hub or switch), [12] [b] it may be possible to capture all traffic on the network from a single machine.
Ettercap is a free and open source network security tool for man-in-the-middle attacks on a LAN.It can be used for computer network protocol analysis and security auditing.It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows.
Sniffing attack in context of network security, corresponds to theft or interception of data by capturing the network traffic using a packet sniffer (an application aimed at capturing network packets). When data is transmitted across networks, if the data packets are not encrypted, the data within the network packet can be read using a sniffer. [1]
As such, degradations of the name may evolve, such as "C@7L0vr." As the leet cipher is highly dynamic, there is a wider possibility for multiple users to share the "same" name, through combinations of spelling and transliterations. Additionally, leet—the word itself—can be found in the screen-names and gamertags of
Sniffer may refer to: Packet analyzer (aka network analyzer, protocol analyzer or sniffer), computer software or hardware that can intercept and log traffic passing over a digital network The trademark for the original Network General Sniffer protocol analyzer
The Sniffer [1] was a computer network packet and protocol analyzer developed and first sold in 1986 by Network General Corporation [2] of Mountain View, CA. By 1994 the Sniffer had become the market leader [ 3 ] in high-end protocol analyzers.
A packet generator or packet builder is a type of software that generates random packets or allows the user to construct detailed custom packets. Depending on the network medium and operating system, packet generators utilize raw sockets , NDIS function calls, or direct access to the network adapter kernel-mode driver .
