VBoxHeadless - Running Virtual Machines With VirtualBox 3.0 On A Headless Ubuntu 9.04 Server

Post date: July 19, 2009, 11:07 Category: Installing Views: 2716 Comments
Tutorial quote: This guide explains how you can run virtual machines with Sun VirtualBox 3.0 (released on June 30, 2009) on a headless Ubuntu 9.04 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Port Knocking

Post date: April 16, 2005, 10:04 Category: Network Views: 3610 Comments
Tutorial quote: Firewall administrators are challenged to balance flexibility and security when designing a comprehensive rule set. A firewall should provide protection against malfeasants, while allowing trusted users to connect. Unfortunately, it is not always possible to filter out the bad guys, because filtering on the basis of IP addresses and ports does not distinguish connecting users. Bad guys can and do come from trusted IP addresses. Open ports remain a necessary vulnerability: they allow connections to applications but also may turn into open doors for attack. This article presents a new security system, termed port knocking, in which trusted users manipulate firewall rules by transmitting information across closed ports.

VMware Server 2.0.2-x On Ubuntu Server 10.04 With VMware Remote Console Plug-in

Post date: August 24, 2010, 16:08 Category: Installing Views: 4792 Comments
Tutorial quote: Today I will tell you how to set up a new Ubuntu 10.04 server which runs VMware server 2.0.2-x and the VMware Remote Console Plug-in. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).
