dsniff
dsniff is a collection of tools for network auditing and penetration testing. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). arpspoof, dnsspoof, and macof facilitate the interception of network traffic normally unavailable to an attacker (e.g, due to layer-2 switching). ...
ipsumdump
The ipsumdump program summarizes TCP/IP dump files into a self-describing ASCII format easily readable by humans and programs. Ipsumdump can read packets from network interfaces, from tcpdump files, and from existing ipsumdump files. It will transparently uncompress tcpdump or ipsumdump files when necessary. It can randomly sample traffic, filter traffic ...
driftnet
Inspired by EtherPEG, Driftnet is a program which listens to network traffic and picks out images from TCP streams it observes. Fun to run on a host which sees lots of web traffic.
PktAnon
PktAnon performs network trace anonymization. It is highly configurable and uses anonymization profiles. Anonymization profiles allow for mapping of arbitrary anonymization primitives to protocol attributes, thus providing high flexibility and easy usability. A huge number of anonymization primitives and network protocols are supported and ready to use for online and ...
tcpflow
tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like 'tcpdump' shows a summary of packets seen on the wire, but usually doesn't store the data that's actually ...
Tcpreplay
Tcpreplay is a suite of BSD licensed tools written by Aaron Turner for UNIX (and Win32 under Cygwin) operating systems which gives you the ability to use previously captured traffic in libpcap format to test a variety of network devices. It allows you to classify traffic as client or server, ...
hping
hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many ...
EIGRP-tools
EIGRP-tools is a custom EIGRP packet generator and sniffer combined. It was developed to test the security and overall operation quality of the EIGRP routing protocol. Using this tool requires you to have the requisite background knowledge of EIGRP, packets structure/types, alongside a good working background of the Layer 3 ...
ike-scan
ike-scan is a command-line tool that uses the IKE protocol to discover, fingerprint and test IPsec VPN servers.
ngrep
ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes TCP, UDP, ICMP, IGMP and Raw protocols across ...
