DSVPN is a Dead Simple VPN, designed to address the most common use case for using a VPN. Runs on TCP. Works pretty much everywhere, including on public WiFi where only TCP/443 is open or reliable. Uses only modern cryptography, with formally verified implementations. Small and constant memory footprint. Doesn't perform any heap memory allocations. Small (~25 KB), with an equally small and readable code base. No external dependencies. Works out of the box. No lousy documentation to read. No...

OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.

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...

NXLog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept it is similar to syslog-ng or rsyslog but is not limited to unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP or TLS/SSL . It supports platform specific sources such as the Windows Eventlog, Linux kernel logs, Android logs, local syslog etc. Writing and reading logs to/from databases is also supported....

pfck is a perl script that reads the state table of pf and reports back flows based on a supplied port number. pfck is very handy in ddos attacks to identify who's hitting a host or network on a particular port service, and who they are specifically hitting.

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.

Authpfng is a new authentication back-end to allow people to sign in to the network administrated by an OpenBSD pf-firewall. Login can be done by ssh, web-based and smb. You can assign traffic quotas and QoS per-user or after a certain bandwidth usage.

Impost is a network security auditing tool designed to analyze the forensics behind protocol exploitation.

Shoki is a free, open source network intrusion detection system. The fundamental design goals are simplicity and modularity, and the focus is on traffic analysis rather than content inspection.

Packet Filter (PF) is OpenBSD\'s firewall and traffic shaper. This is a port of this excellent software to FreeBSD.

my-swatch pretends to be an implementation of msyslog and swatch together. What it pretends to accomplish is put all together, to log events to a remote database (like msyslog) and to awake triggers (like swatch).

SIDEN is a distributed network discovery tool used for intrusion detection research purposes. It simulates coordinated/distributed network probes against a network. The traffic generated can then be analyzed to improve Intrusion Detection Systems.
