Ports Search

The tool is a simple flow-analyzing passive L7 fingerprinter. It examines the sequence of client-server exchanges, their relative layer 7 payload sizes, and transmission intervals (as opposed to inspecting the contents, which is what most passive fingerprinters and "smart" sniffers would do to analyze transmissions). This is then matched against a database of traffic pattern signatures to infer some interesting facts about the traffic.

TLS / SSL native driver for Erlang from ProcessOne

Fast Expat based Erlang XML parsing library, with a strong focus on XML stream parsing from network.

[ excerpt from developer's web site ] Using JNI (Java Native Interface), a bit of C code (thanks ugha!), a little manual work and a piece of chewinggum: it is possible to make the public key cryptography quite a bit faster.

Bitmessage is a decentralized, encrypted, peer-to-peer, trustless communications protocol that can be used by one person to send encrypted messages to another person, or to multiple subscribers.

Tribler is a social community that facilitates filesharing through a so called peer-to-peer (p2p) network. A p2p network is structural different to a server-computer structure, where every user downloads its files from one central server. Within p2p the user/downloader becomes also an uploader to the next user. In this way there is no central computer that provides every file to all users.

C++ implementation of I2P client

libixp is a stand-alone client/server 9P library including ixpc client which behaves like wmiir in the past. It consists of less than 2000 lines of code (including ixpc). libixp's server API is based heavily on that of Plan 9's lib9p, and the two libraries export virtually identical data structures.

This module provides shortcuts when performing repetitive information-retrieval tasks with p5-SNMP.

This is the Tcl/Tk frontend to Perforce's p4. You have to have p4-client binary installed -- it is available from The actual front-end is by Rick Macdonald <rickm@vsl.com>:
