Free p2p networks software for linux

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.

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

network-config is a simple network configuration tool.

Network-config is a simple and easy to use program that helps configuring the network interfaces for linux-based operating systems. It allows to have multiple configurations for the same computer and to easy configure NAT for internet sharing.

It can also be used to scan for wireless networks. It is written in perl and uses gtk2+, but also works as a command line program.

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)

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

Netleak is a collection of small perlscripts that detects connectivity between network segments. It is mostly useful to detect "leaks" in large organizations that have private networks physically separated from the Internet.


Imagine some large corporation which has an internal development LAN were all sorts of sensitive information is flowing around. This corporation would likely have some very strict rules as to how its employees access the internet or other partner branches in order to
protect its information. For the systemadinistrator this is a daunting task - as the corporate LAN grows keeping track of all the routes through the network becomes extremely difficult. Some routers might simply have been forgotten over time or an employee might have gone wise and connected his own adsl-router or something alike.

Network Leak Finder tries to detect this in a centralized manner by sending out spoofed packets into the internal network and if any packets finds a way onto the external network, a "leak" has been detected. As an anology it works the same way you would find a hole in
a bucket: fill it with water and see if anything leaks.

In most scenarios the external network would be the Internet since everybody should be afraid of what their corporate LANs are leaking to it!

Neural Network Framework project is a C++ framework to develop, simulate, and analyze arbitrary complex neural networks.
The programmer can use the classes provided to create neural networks with arbitrary topology and mixed type of neurons. Its very easy to add customized neurons and layers.
Enhancements:
- A ScaleFunction that scales the input vector of a Cluster and a normalize method for RealVec were added.
- Two methods were added to the Random class to randomize RealVec and RealMat.

Network Configurator is a network configuration tool.
Network Configurator is user-level tool that aims to make network configuration more easy. It have command line and GTK+ interface.
Supported network types:
- Ethernet
- PPPoE
- PPTP
- Wi-Fi (no WEP and WPA for now)
- dialup
