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.

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.

xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661). L2TP allows you to tunnel PPP over UDP.

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.

Bitmask, by LEAP, is an application to provide easy and secure encrypted communication with a VPN. It allows you to select from a variety of trusted service provider all from one app. Current providers include Riseup Networks and The Calyx Institute, where the former is default.

Openfortivpn is a client for PPP+SSL VPN tunnel services. It spawns a pppd process and operates the communication between the gateway and this process. It is compatible with Fortinet VPNs.

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.

This is a helper script to allow you to interactively login to a GlobalProtect VPN that uses SAML authentication, so that you can subsequently connect with OpenConnect.

n2n is a light VPN software which makes it easy to create virtual networks bypassing intermediate firewalls.

vpnc is a VPN client compatible with Cisco's EasyVPN equipment. It supports IPSec (ESP) with Mode Configuration and Xauth. It supports only shared-secret IPSec authentication with Xauth, AES (256, 192, 128), 3DES, 1DES, MD5, SHA1, DH1/2/5 and IP tunneling. It runs entirely in userspace. Only "Universal TUN/TAP device driver support" is needed in the kernel.

OpenVPN implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls.

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

User-level SOCKS and port forwarding proxy for OpenConnect based on LwIP. When using ocproxy, OpenConnect only handles network activity that the user specifically asks to proxy, so the VPN interface no longer "hijacks" all network traffic on the host.

This is the official command-line interface for ProtonVPN, a secure point-to-point virtual private networking (VPN) service with a gratis tier. It can automatically find and connect to the fastest servers or use Tor over VPN. The gratis tier offers unlimited bandwidth for up to 10 devices.

Tinc is a VPN that uses tunnelling and encryption to create a secure private network between hosts on the internet.

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).

The GNU Virtual Private Ethernet creates a virtual network with multiple nodes using a variety of transport protocols. It works by creating encrypted host-to-host tunnels between multiple endpoints.

OpenConnect is a client for Cisco's AnyConnect SSL VPN, which is supported by the ASA5500 Series, by IOS 12.4(9)T or later on Cisco SR500, 870, 880, 1800, 2800, 3800, 7200 Series and Cisco 7301 Routers, and probably others.

vkd3d is a library for translating Direct3D 12 to Vulkan.

Utility libraries for Vulkan developers.

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.

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.

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.
