Looking Glass allows the use of a KVM (Kernel-based Virtual Machine) configured for VGA PCI Pass-through without an attached physical monitor, keyboard or mouse. It displays the VM's rendered contents on your main monitor/GPU.

V is a systems programming language. It provides memory safety and thread safety guarantees with minimal abstraction.

Remmina is a client to use other desktops remotely. RDP, VNC, SPICE, NX, XDMCP, SSH and EXEC network protocols are supported.

TurboVNC is a high-speed version of VNC derived from TightVNC, with which it remains compatible. It contains a variant of Tight encoding that is tuned to maximize performance for image-intensive applications (such as VirtualGL, video applications, and image editors) while still providing excellent performance for other types of applications. Some of its unique features are:

• a user-facing vncserver command;

• the ability to capture keyboard keys even when not in full screen mode;

• a full screen mode that is compatible with ratpoison*

*Although due to a quirk in Java, you'll want to set the _JAVA_AWT_WM_NONREPARENTING environment variable when using it with ratpoison.

This package provides LibVNCServer and LibVNCClient. These are cross-platform C libraries that allow you to easily implement VNC server or client functionality in your program.

NeatVNC is a lightweight VNC server library, supporting authentication, SSH tunneling, and ZRLE or Tight encoding.

This is a VNC server for wlroots-based Wayland compositors. It attaches to a running Wayland session, creates virtual input devices, and exposes a single display via the RFB protocol. The Wayland session may be a headless one, so it is also possible to run wayvnc without a physical display attached.

x11vnc allows one to view and interact with real remote X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer.

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.

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.

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

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).

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

This package provides the user-space command-line tools for using and configuring WireGuard tunnels.

WireGuard is a simple and fast general-purpose VPN that securely encapsulates IP packets over UDP. It aims to be as easy to configure and deploy as SSH. VPN connections are made simply by exchanging public keys and can roam across IP addresses.

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.

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.

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.

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.

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.

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.

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

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.

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.
