Client for Cisco VPN concentrator.

This is a piece of software that lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed. It ... [More] runs on Linux, Mac OS X, FreeBSD, NetBSD and OpenBSD and needs a TUN/TAP device. The bandwidth is assymetrical with limited upstream and up to 1 Mbit/s downstream. [Less]

strongSwan is an OpenSource IPsec implementation for the Linux operating system. It is based on the discontinued FreeS/WAN project and the X.509 patch which we developed over the last three years. It ... [More] features IKEv1 and IKEv2 keying capabilities and targets Linux 2.6 native IPsec. [Less]

Anytun is an implementation of the secure anycast tunneling protocol. It uses an easy openvpn style interface and makes it possible to build redundant vpn clusters with load balancing between servers. ... [More] VPN Servers share a single IP address. Adding and removing VPN Servers is done by the routing protocol, so no client changes have to be made when additional VPN Servers are added or removed. It is possible to realise global load balancing based on shortest BGP routes, by simply announcing the address space of the tunnel servers at multiple locations. [Less]

tinc is a daemon with which you can create a virtual private network (VPN). One daemon can handle multiple connections, so you can create an entire (moderately sized) VPN with only one daemon per ... [More] participating computer. tinc can tunnel IPv4, IPv6 and/or Ethernet packets over IPv4 and IPv6 networks. [Less]

This project is for programmers needing a working SSH implementation by the mean of a library. The complete control of the client is made by the programmer. With libssh, you can remotely execute ... [More] programs, transfer files, use a secure and transparent tunnel for your remote programs. With its Secure FTP implementation, you can play with remote files easily, without third-party programs others than libcrypto (from openssl). [Less]

µAnytun is a tiny implementation of SATP. Unlike Anytun which is a full featured mplementation µAnytun has no support for multiple connections or synchronisation. It is a small single threaded ... [More] implementation intended to act as a client on small platforms. [Less]

SSHTunneler allows you to easily manage SSH tunnels for yourself. Also, by using the SSHTunnelerPackager, a system administrator can distribute SSHTunneler installation package bundled with a config ... [More] file. By doing so, he can make his users use SSH tunnels without them even knowing so. Right now, the project is in early alpha stage. In fact, the SSHTunnelerPackager should not be able to generate installers. [Less]

This is a proof-of-concept implementation of Dan Kaminsky's so-called "DNS source routing" hack. WHAT IT DOES: establish inbound IP traffic to a host inside a private network, with no public IP ... [More] address nor DNAT setup. HOW IT WORKS: the private network's local dns resolver is fooled into relaying trafic back in forth. REQUIREMENTS:     - The target network must host a local dns resolver     - The dns resolver must be able to establish UDP/53 connections towards the target     - The attacker must have authority on a zone somewhere in the DNS hierarchy     - The attacker must trigger an initial DNS request for the zone he controls from inside the target network (there are many ways to do so) More in-depth documentation will be included, as the available documentation is scarse to say the least.
