This article describes a method for remotely accessing virtual servers. The aim is to be able to have multiple clients access one or more virtual servers across one or more physical hosts as if everyone was on the same LAN. It is also necessary to do this without compromising on security and without ANY extra configuration for the virtual servers.
We will achieve this using Qemu and Openvpn.

An SSL portal isn't as secure as a real VPN (virtual private network) such as OpenVPN, but it's easier to set up and is good for specific functions. The Untangle gateway makes setting up and managing an SSL-based Web portal fast and easy; Eric Geier shows how.

I get this question often from many: How does one use a Virtual Private Network in Linux?

Ask any knowledgeable mobile user, and she will tell you that the best way to securely access the Internet in public places is through a VPN (virtual private network) connection.

OpenSSH version 4.3 introduced a new feature: the ability to create on-the-fly "Virtual Private Networks" via the tunnel driver (the so-called "tun" driver). This allows you to create a network interface that bridges two physically disparate network segments in different locations.

One of the biggest obstacles to personal email management is lack of user demand for Virtual Personal Email Server (VPES) software.

"...This article will document a simple, single PKI infrastructure to manage all your users and their VPN connections with support for both OpenSWAN and OpenVPN..."

This image represents a basic network plan for a small company. The goal of this article is to use this image to help describe basic concepts of networks and how they typically constructed as well as why they are designed the way they are. Of course there are many variations to this basic design.

Virtual machines are virtually taking over the world. By itself a virtual machine is just a container that describes various resources such as memory, disk space, processor, and network card, and allocates them from a physical machine. As with a physical machine, it's the software bits (the operating system and applications) that make a virtual machine usable.
