pystun - A Python STUN client for getting NAT type and external IP

  •        216

A Python STUN client for getting NAT type and external IP. PyStun follows RFC 3489, A server following STUN-bis hasn't been found on internet so RFC3489 is the only implementation.

PyPunchP2P - Python实现NAT穿透+STUN+TURN+P2P聊天 | Python P2P chat

Python p2p chat client/server with built-in NAT traversal (UDP hole punching). I've written an article about the detailed implementation (in Chinese). The number 100 is used to match clients, you can choose any number you like but only clients with the same number will be linked by server. If two clients get linked, two people can chat by typing in terminal, and once you hit <ENTER> your partner will see your message in his terminal. Encoding is a known issue since I didn't pay much effort on making this tool perfect, but as long as you type English it will be fine.

PeerVPN - the open source peer-to-peer VPN

PeerVPN is a software that builds virtual ethernet networks between multiple computers. Such a virtual network can be useful to facilitate direct communication that applications like file sharing or gaming may need. Often, such direct communication is made impossible or very difficult by firewalls or NAT devices.

PonyDebugger is a remote debugging toolset. It is a client library and gateway server combination that uses Chrome Developer Tools on your browser to debug your application's network traffic and managed object contexts.To use PonyDebugger, you must implement the client in your application and connect it to the gateway server. There is currently an iOS client and the gateway server.


This is Metasploitable2 (Linux) Metasploitable is an intentionally vulnerable Linux virtual machine. This VM can be used to conduct security training, test security tools, and practice common penetration testing techniques. The default login and password is msfadmin:msfadmin. Never expose this VM to an untrusted network (use NAT or Host-only mode if you have any questions what that means). To contact the developers, please send email to

cpp-netlib - The C++ Network Library Project

The project aims to build upon the latest C++ standard (currently C++11) to provide easy to use libraries for network programming. We use the latest compiler versions and features with an eye on pushing the boundaries on leveraging what's available in C++. Currently the library contains an HTTP client and server implementation, a stand-alone URI library, a network message framework, and some concurrency tools.

network-examples - Linux networking examples and tutorials

Welcome to my Linux Networking tutorials. The first part, learning two widely used routing protocols, OSPF and BGP, is almost completed. You've been a Linux server and network administrator for some years, have been building an office and/or colocation network with IPv4, IPv6, firewalls with IPTables, some stateful filtering (and NAT for IPv4). You've set up VPN tunnels between different locations to be able to reach the internal IPv4 network using RFC1918 addresses on the other side.

LVS - A distribution of Linux Virtual Server with some advanced features

A distribution of Linux Virtual Server with some advanced features.FullNAT: A new packet forwarding method for IPVS, other than DR/NAT/TUNNEL The main principle is as follows: the module introduces local ip address (IDC internal ip address, lip), IPVS translates cip-vip to/from lip-rip, in which lip and rip both are IDC internal ip address, so that LVS load balancer and real servers can be in different vlans, and real servers only need to access internal network. See Virtual Server via Full NAT for more information.

Tinc - a VPN daemon

tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet. All traffic is optionally compressed using zlib or LZO, and LibreSSL or OpenSSL is used to encrypt the traffic and protect it from alteration with message authentication codes and sequence numbers.

tcpreplay - Pcap editing and replay tools for *NIX and Windows - Users please download source from

Tcpreplay is a suite of GPLv3 licensed utilities for UNIX (and Win32 under Cygwin) operating systems for editing and replaying network traffic which was previously captured by tools like tcpdump and Ethereal/Wireshark. It allows you to classify traffic as client or server, rewrite Layer 2, 3 and 4 packets and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS's. Tcpreplay supports both single and dual NIC modes for testing both sniffing and in-line devices.Tcpreplay is used by numerous firewall, IDS, IPS, NetFlow and other networking vendors, enterprises, universities, labs and open source projects. If your organization uses Tcpreplay, please let us know who you are and what you use it for so that I can continue to add features which are useful.
