The WendzelNNTPd is a IPv6-ready NNTP usenet-server with the main goal to be as easy to use as possible. It is portable (Linux/*BSD/*nix), supports AUTHINFO authentication, contains ACL as well as role based ACL and supports invisible newsgroups. It currently supports MySQL and SQLite backends.

Calypso is a file sharing client using the anonymous network MUTE. Developped using C++ and Qt. For windows and linux, portable to other environments.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

Introduction Sudoscriptd/sudoshell are a pair of Perl scripts that provide an audited shell using sudo(8) and script(1).

The Neighbor Discovery Protocol Monitor (NDPMon) is used by Internet Protocol version 6 network administrators for monitoring ICMPv6 packets. NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report. It may also execute a user-defined script. For IPv6, NDPMon is an equivalent of Arpwatch for IPv4, and has similar basic features with added attacks detection. NDPMon also maintains up-to-date a list of neighbors on the link and watches all advertisements and changes. It permits to track the usage of cryptographically generated interface identifiers or temporary global addresses when Privacy extensions are enable (default behavior in Ubuntu and Windows for example).

Wraith is an open source IRC bot written in C++. It has been in development since late 2003. It is based on Eggdrop 1.6.12 but has since evolved into something much different at its core.

This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

IMPORTANT -- This is an old project that is no longer supported and should not be relied upon for serious applications. If your looking for encryption software, I suggest OpenSSL or GnuPG which are better equipped.

Snort2Pf is a small Perl daemon which greps Snort's alertfile and blocks the "naughty" hosts for a given amount of time using pfctl.

pam_mount is a Pluggable Authentication Module that can mount volumes for a user session (login). Supports mounting local filesystems of any kind the normal mount utility supports, with extra code to better support CIFS, FUSE, various crypto, and more.

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.

A simple DOS attack tool based on the public resources response time.

SecurityFusion is an open source network intrusion detection and prevention system based in Hogwash, capable of performing real-time traffic analysis and packet logging on IP networks.

Gobbler: A tool to audit DHCP networks Includes DHCP rogue server detection, DHCP DoS, distributed spoofed port scanner using DHCP to obtain many source IP addresses, mulitple arp scans, filtered port detection, spoofed OS detection (nmap + port 0)

The UnifiedSessionsManager supports the integrated management of user sessions within Private-Clouds, comprising heterogeneous IT landscapes of various physical and virtual machines, hypervisor management, and virtual user sessions with remote desktops. Extracted documents see https://sourceforge.net/projects/ctys-doc.

A resource-conscientious, flexible, modular, platform-independent, scalable and robust server based on ircd-ratbox.

This is a list of advertising domains that can be used with a proxy server to remove unwanted advert traffic from the network. This list is directly compatible with tinyproxy, but may also work with other proxy servers.

Anoubis is a Security Suite which implements a secured environment for applications. The core of the suite is an Application Firewall alongside with a Sandbox. Mechanisms to assure the authenticity of files, directories and applications are provided.
