Free capturix networks software for linux

Java Network Stack provides a Java library for research oriented network programming.

Java Network Stack is a library used by the DIMES project to create new internet measurements. It provides a clean API for packet manipulation, send, receive, filter, and analysis. It is a unification of raw socket capabilities, MAC level networkingm, and IPv6 capabilities.

NetworkX is a Python package for the creation, manipulation, and study of the dynamics, structure, and functions of complex networks.
Main features:
- Allows for 1M+ nodes, 10M+ edges
- Includes standard graph-theoretic and statistical physics functions
- Easy exchange of network algorithms between applications, disciplines, and platforms
- Includes many classic graphs and synthetic networks
- Nodes and edges can be "anything" (e.g. time-series, text, images, XML records)
- Exploits existing code from high-quality legacy software in C, C++, Fortran, etc.
- Open source (encourages community input)
- Unit-tested
Additional benefits due to Python:
- Allows fast prototyping of new algorithms
- Easy to teach
- Multiplatform
- Allows easy access to almost any database

lisp-network-server is a simple framework for writing Common Lisp network applications.

lisp-network-server framework takes care of listening on the network, accepting the connection and starting a new thread with handler functions of your network aware application.

Jimsim Network Simulator project can emulate several routers connected via virutal networks. You can connect to the routers with your own favorite telnet program.
Connecting to the Virtual Routers
Use your favorite telnet program to connect to each of the virtual routers. For example:
For router 1 type:
C:>telnet localhost 10000
For router 2 type:
C:>telnet localhost 10001
For router 3 type:
C:>telnet localhost 10002
Network Layout
Currently the network is configured like this:
access-list [1-99] [permit/deny] [ ip wildcard-mask | host a.b.c.d | any ]
ip acccess-list [standard] [name]
ip access-group
show access-list
show ip interface
show ip interface brief
debug interface
encapsulation [hdlc,ppp] (serial interfaces only)
bandwidth
clock rate (serial interfaces)
interface loopback0
User commands:
?
enable
exit
ping ip
show cdp
show cdp neigh
show cdp neigh detail
show interface
show interface e0,eth0,etc
show ip route
show version
Enable commands:
clear counters
clear counters interface
config terminal
copy running startup
copy startup running
debug all
debug ip routing
debug ip eigrp
debug cdp
disable
exit
reload
show run
show startup
show ip eigrp neighbors
show ip eigrp topology
traceroute ip
undebug all
undebug ip routing
undebug ip eigrp
undebug cdp
Config commands:
cdp run
enable password password
end
hostname
banner motd delimiter
banner exec delimiter
banner login delimiter
ip route network netmask dest
interface e0,eth0,etc
bandwidth value
ip address addr netmask
description
cdp enable
shutdown
line con0, console0, console 0
login
login local
password passwd
router eigrp number
network a.b.c.d
service password-encryption
user username password password
Version restrictions:
- The EIGRP support is very basic. Just the network command for now. (Neighbors dont expire.) You can disable EIGRP with "no router eigrp process_id"
- The routing table isnt 100% correct. It doesnt summarize subnets. Nor does it understand multiple routes to the same destination. This will be fixed in the next version.
- Traceroute seems to count extra hops. Its counting each remote interface on a router as a hop. So, when you traceroute from router1 to router3, it counts router2 twice (once for 192.168.1.2 and 10.1.1.1)

SocNetV is a Linux GUI program written in Qt3.
Social Networks Visualiser project main purpose is to bring to our Linux box comprehensive Social Networks Analysis and Visualisation.
It can read and write various network file formats and enables the user to visually modify an existing network or draw a new network using the mouse. Network and actor properties, such as distances, centralities, diameter etc, can be easily computed. Also, it can create random networks (lattice, same degree, etc).
SocNetV is NOT antagonistic to any commercial/scientific SNA programs, like PAJEK, visone, UCINET, AISee, KrackPlot, which are developed by groups of professionals and scientists. It is rather a personal trip to learn SNA and C++ programming while keeping the code open for others to learn from my mistakes. If you find it useful Ill be glad. But be aware that there is no warranty of efficiency, correctness or usability.
Oh, and this site is under never-ending construction as well.
Installation:
To see SocNetV in action, you need a modern Linux distro with Qt 3.x. Download the latest release from the link "Download" on the left. Untar the archive, cd to the new directory, and use:
/usr/lib/qt3/bin/qmake (or wherever are your Qt libs)
make
./socnetv
Enhancements:
- tarball of v. 043.1 was corrupted. fixed.
- Fixed display of HTML help in Debian package.
- Fixed wrong numbering of new actors with double-click.
- Fixed creation of links through middle-click.

Ruby Iptables NEtwork Displayer project draws an SVG from a Linux IP table generated by "iptables-save".

Network Simulator (Ns) is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.
Ns began as a variant of the REAL network simulator in 1989 and has evolved substantially over the past few years. In 1995 ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UCB, and USC/ISI.
Currently ns development is support through DARPA with SAMAN and through NSF with CONSER, both in collaboration with other researchers including ACIRI. Ns has always included substantal contributions from other researchers, including wireless code from the UCB Daedelus and CMU Monarch projects and Sun Microsystems.
Enhancements:
- Major updates were made to the PackMime-HTTP HTTP/1.1 and WPAN modules.
- Solaris/Sun C compilation bugs were fixed.
