sshuttle creates an encrypted virtual private network (VPN) connection to any remote server to which you have secure shell (SSH) access. The only requirement is a suitable version of Python on the server; administrative privileges are required only on the client. Unlike most VPNs, sshuttle forwards entire sessions, not packets, using kernel transparent proxying. This makes it faster and more reliable than SSH's own tunneling and port forwarding features. It can forward both TCP and UDP traffic, including DNS domain name queries.

StrongSwan is an IPsec implementation originally based upon the FreeS/WAN project. It contains support for IKEv1, IKEv2, MOBIKE, IPv6, NAT-T and more.

BadVPN is a collection of virtual private network (VPN) tools. It includes:

1. NCD programming language.

   NCD (Network Configuration Daemon) is a daemon and programming/scripting language for configuration of network interfaces and other aspects of the operating system.

2. Tun2socks network-layer proxifier.

   The tun2socks program socksifes TCP connections at the network layer. It implements a TUN device which accepts all incoming TCP connections (regardless of destination IP), and forwards the connections through a SOCKS server.

3. Peer-to-peer VPN.

   The peer-to-peer VPN implements a Layer 2 (Ethernet) network between the peers (VPN nodes).

This package contains an out-of-tree kernel patch and a loadable module adding WireGuard to Linux kernel versions 3.10 through 5.5. WireGuard was added to Linux 5.6.

This set of scripts configures routing and name services when invoked by the VPNC or OpenConnect Cisco Virtual Private Network (VPN) clients.

The default vpnc-script automatically configures most common connections, and provides hooks for performing custom actions at various stages of the connection or disconnection process.

Alternative scripts are provided for more complicated set-ups, or to serve as an example for writing your own. For example, vpnc-script-sshd contains the entire VPN in a network namespace accessible only through SSH.

vpn-slice is a replacement for vpnc-script used by openconnect and vpnc. Instead of trying to copy the behavior of standard corporate VPN clients, which normally reroute all your network traffic through the VPN, vpn-slice tries to minimize your contact with an intrusive VPN. This is also known as a split-tunnel VPN, since it splits your traffic between the VPN tunnel and your normal network interfaces.

By default, vpn-slice only routes traffic for specific hosts or subnets through the VPN. It automatically looks up named hosts, using the VPN's DNS servers, and adds entries for them to your /etc/hosts (which it cleans up after VPN disconnection), however it does not otherwise alter your /etc/resolv.conf at all.

The SPIR-V Tools project provides an API and commands for processing SPIR-V modules. The project includes an assembler, binary module parser,disassembler, validator, and optimizer for SPIR-V.

Shaderc is a collection of tools, libraries, and tests for shader compilation.

The Vulkan Memory Allocator (VMA) library provides a simple and easy to integrate API to help users allocate memory for Vulkan buffer and image storage.

Shaderc is a collection of tools, libraries, and tests for shader compilation.

Vulkan-ValidationLayers provides the Khronos official validation layers that can assist development by enabling developers to verify their applications correctly use the Vulkan API.

Vulkan allows multiple Installable Client Drivers (ICDs) each supporting one or more devices to be used collectively. The loader is responsible for discovering available Vulkan ICDs on the system and inserting Vulkan layer libraries, including validation layers between the application and the ICD.

SPIRV-Headers is a repository containing machine-readable files from the SPIR-V Registry. This includes:

• Header files for various languages.

• JSON files describing the grammar for the SPIR-V core instruction set, and for the GLSL.std.450 extended instruction set.

• The XML registry file.

Utility libraries for Vulkan developers.

SPIRV-Cross tries hard to emit readable and clean output from the SPIR-V, aiming to emit GLSL or MSL that looks like human-written code.

The LLVM/SPIR-V Bi-Directional Translator is a library and tool for translation between LLVM IR and SPIR-V.

Vulkan-Headers contains header files and API registry for Vulkan.

vkBasalt is a Vulkan post processing layer to enhance the visual graphics of games.

Currently, the built-in effects are:

• Contrast Adaptive Sharpening

• Denoise Luma Sharpening

• Fast Approximate Anti-Aliasing

• Enhanced Subpixel Morphological Anti-Aliasing

• 3D color LookUp Table

Vulkan-Headers contains header files and API registry for Vulkan.

Vulkan-Tools provides tools and utilities that can assist development by enabling developers to verify their applications correct use of the Vulkan API.

Volk is a meta-loader for Vulkan. It allows you to dynamically load entrypoints required to use Vulkan without linking the Vulkan loader. Additionally, volk simplifies the use of Vulkan extensions by automatically loading all associated entrypoints. Finally, volk enables loading Vulkan entrypoints directly from the driver which can increase performance by skipping loader dispatch overhead.

vkd3d is a library for translating Direct3D 12 to Vulkan.

Glslang is the official reference compiler front end for the OpenGL ES and OpenGL shading languages. It implements a strict interpretation of the specifications for these languages.

w3m is a text-based web browser as well as a pager like more or less. With w3m you can browse web pages through a terminal emulator window. Moreover, w3m can be used as a text formatting tool which typesets HTML into plain text.
