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: 4832 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).

Installing Oracle VM VirtualBox on Ubuntu

Post date: October 10, 2010, 05:10 Category: Software Views: 5054 Comments
Tutorial quote: What does that mean? For one thing, VirtualBox installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. Secondly, VirtualBox extends the capabilities of your existing computer so that VirtualBox can run multiple operating systems (inside multiple virtual machines) at the same time. So, for example, you can run Windows and Linux on your Mac, run Windows Server 2008 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like -- the only practical limits are disk space and memory.

Using iptables to rate-limit incoming connections

Post date: December 16, 2005, 22:12 Category: Network Views: 4083 Comments
Tutorial quote: There are times when you have to allow arbitary incoming connections, when you are travelling for example.

In these situations you can open up your system to allow incoming connections and be the target of a dictionary attack - literally a machine trying to connect and login over and over again using usernames and passwords from a dictionary.

In this situation you can create a collection of firewalling rules which will deny access from remote clients who attempt to connect "too many" times.

Rebuilding the OpenBSD kernel

Post date: April 24, 2005, 20:04 Category: System Views: 4917 Comments
Tutorial quote: Users who want their OpenBSD machine to perform specific functions or need additional device drivers might want to customize their kernel. In other OS's, like some types of Linux, it is very popular to rebuild the kernel because the default is so bloated. For most users, the default OpenBSD kernel is sufficient; however, you should still apply kernel patches, which will require rebuilding and installing a fresh kernel.
