Conchart is a tool to visualise the timing of network connections. It reads a
pcap file to generate an SVG file. It will show the send and received data as
coloured areas which will allow an aid in network troubleshooting.

constat is a program that allows you to monitor the activity of any network connection that are active. It is simple to install and use, works under any Linux system, and does not require the X server. Information may be output for all connections or just one. Output can be printed in units of KB, MB, or GB, along with the number of transmitted packets. It has a real time monitoring option, based on a 5-second timer.

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). sshmitm and webmitm implement active monkey-in-the-middle attacks against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hoc PKI.

etherdump is an extremely small packet sniffer. It can be used to dump raw
ethernet frames for parsing (optimally with Ethereal's text2pcap), or for
viewing the network traffic of a few common TCP/IP protocols.

Flickcurl provides utilities such as "flickcurl" to exercise the API and "triplr" to get RDF metadata descriptions out of photos, tags, and machine tags.

Googsystray is a system tray app for Google Voice, GMail, Google Calendar,
Google Reader, and Google Wave. The idea is to be able to keep track of all
that stuff without having to keep a bunch of browser tabs open, or constantly
checking them. It notifies on new messages, alerts, etc., and provides basic
services quickly (Reading or sending a new SMS message, or marking an email
read, for example.)

The HTTP Time Protocol (HTP) system is a set of utilities to set and maintain the system clock from the HTTP/1.1 (RFC 2616) "Date:" header.
The purpose of HTP is provide a simple to use system that can be used on any system that is connected to the internet and can access atleast one web page (either directly or through a proxy) to be able to maintain an accurate clock.
HTP uses basic statistical analysis to arrive at the most accurate time possible given enough servers. The more servers HTP is configured to use the more accurate the clock can be.

Httping is like 'ping' but for http-requests.
Give it an URL, and it'll show you how long it takes to connect, send a request and retrieve the reply (only the headers). Be aware that the transmission across the network also takes time!

HTTPTunnel is a simple client/server application for creating an HTTP tunnel between two machines, optionally via a Web proxy. This tunnel can then be used to wrap arbitrary TCP socket traffic in HTTP, thus allowing communications even through a restrictive firewall that only allows outgoing HTTP connections.

imap2mbox is a simple script that save remote IMAP4 folders to local mbox
files. It can be very useful if you need to save your remote mailboxes.

It also supports creating an HTML archive.

Inputpipe is a client/server application for making any Linux input device network-transparent.
An inputpipe client runs on a computer with some arbitrary input devices, forwarding information and status from those devices to an inputpipe server.
The server creates local input devices that are for all practical purposes identical copies of the devices being forwarded.

ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values.

jig is a console based jabber client. The UI is modeled after bsflite. It will be kept as simple as possible, while maintaining as many features as possible (GPG encryption, file transfers, etc).

justniffer is a tcp packet sniffer. It captures reassembles and reorders TCP packets, performs IP packet defragmentation and displays the tcp flow and trace timings. It is useful for logging network traffic in a 'standard' (web server like) or in a customized way. It can log http response time, useful for tracking network services performances (e.g. web server, application server, etc.)

LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls.

More importantly, LFT implements numerous other features, including AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more.

LFT also distinguishes between TCP-based protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.

Libmetalink is a Metalink library written in C language. It is intended to
provide the programs written in C to add Metalink functionality such as parsing
Metalink XML files.

Libopennet allows you to open_net() files the same way you open() them now.

The purpose of this library is to read tcpdump trace files with the ability to navigate around in the file between reads. The API is intentionally much like that of the pcap library.

You can navigate in trace files both in time and space: you can jump to a packet which is at appr. 2/3 of the trace, or you can jump as closely as possible to a packet with a given timestamp, and then read packets from there. In addition, the API provides convenience functions for manipulating timeval structures.

STFL is a library which implements a curses-based widget set for text terminals. The STFL API can be used from C, SPL, Python, Perl and Ruby. Since the API is only 14 simple function calls big and there are already generic SWIG bindings it is very easy to port STFL to additional scripting languages.

A special language (the Structured Terminal Forms Language) is used to describe STFL GUIs. The language is designed to be easy and fast to write so an application programmer does not need to spend ages fiddling around with the GUI and can concentrate on the more interesting programming tasks.

lifstat is a small Linux utility that reads /proc/net/dev and reports input and
output statistics for available network interfaces over a repeating time
interval, similar to the BSD 'netstat -i' command.

mbuffer is a raplacement for buffer with additional functionality:
- display of I/O speed
- optional use of memory mapped I/O for huge buffers
- multithreaded instead of sharedmemory ipc
- multi volume support
- autoloader support
- networking support
- compatible command-line options

Metalink is the main Metalink generation tool. It combines a list of mirrors (from stdin) and a number of files into one Metalink record (stdout). It can also be used to transform a MD5SUMS file into a metalink.
