libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, creating guests, P2V, V2V, performing backups, cloning VMs, building VMs, formatting disks, resizing disks, and much more.

Spike, the RISC-V ISA Simulator, implements a functional model of one or more RISC-V harts.

This package contains a set of tools to assist administrators and developers in managing the database.

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

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

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.

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

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.

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.

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.

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.

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.

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.

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

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

sshoot provides a command-line interface to manage multiple sshuttle virtual private networks. It supports flexible profiles with configuration options for most of sshuttle’s features.

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.

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.

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.

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.

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.

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.

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