Open source container-based virtualization for Linux.
OpenVZ allows multiple secure, isolated Linux containers (also known as virtual private servers or virtual environments) to run on a single physical server. This technology enhances server utilization and ensures that applications do not conflict with each other.

tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet. tinc is Free Software and licensed under the GNU General Public License version 2 or later. Because the VPN appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This allows VPN sites to share information with each other over the Internet without exposing any information to others.
A ssl/ssh multiplexer.
Applicative Protocol Multiplexer (e.g. share SSH and HTTPS on the same port).
sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.
Probes for HTTP, TLS/SSL (including SNI and ALPN), SSH, OpenVPN, tinc, XMPP, SOCKS5, are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to SSH from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.

Stealth tunneling through HTTP(S) proxies.
This is proxytunnel, a program that connects stdin and stdout to an origin server somewhere in the Internet through an industry standard HTTPS proxy. I originally wrote this program to be used as an extension to SSH, to be able to SSH to my box at home. In this file, I will describe the use with SSH. If you want to use it with some other application, feel free, and let me know!

Fuzzowski-based OPCUA fuzzer.
Fuzzing should never be conducted on production equipment or systems. This testing technique can cause unexpected behavior, system crashes, data corruption, or security vulnerabilities. Always perform fuzzing in a controlled, isolated environment to ensure the safety and stability of production systems.
FuzzySully is an OPC UA fuzzer built upon Fuzzowski. It is a specialized testing tool designed to identify vulnerabilities and bugs in OPC UA (Open Platform Communications Unified Architecture) implementations. These fuzzers typically operate by generating and sending a large number of malformed or unexpected messages to an OPC UA server or client, with the goal of triggering unexpected behavior or crashes.
