I was standing in front of a problem while I built a NFS Storage Server. It is necessary for me to have redundancy in every point of view. I solved all redundancy issues I had by using server hardware with redundant power supplies, a Raid 1+ 0 Raid array and two UPS’s one for each power supply. The only thing left in my mind was what about a network failure? Well just use the two Gig NIC’s and hook each of them up to its own switch. Great idea but how do I get them acting as one unit speak one single IP? NIC Bonding was my solution. After a couple of hours researching on the Internet stumbled upon the build in solution by using ifenslave.

Here is how I did it:

In order to get fault tolerance we are going to bond the NICs. We need to compile a little program that will

Security is based on three characteristics: prevention, protection and detection. Grsecurity is a patch for Linux kernel that allows you to increase each of these points.

This howto was performed on a Debian Lenny system. Thus some tools are Debian specific. However, tasks can be performed with other distro specific tools or even with universal tools (make).

Everything will done with root privileges. However, you can perform them with a limited account thanks to sudo and fake-kpkg tools.

To compile the kernel, you need to install some specific packages:

rom1:/root# aptitude install patch bin86 kernel-package build-essential

If you like to configure your kernel in graphical console mode (make menuconf

FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on an Ubuntu 8.10 server.

I do not issue any guarantee that this will work for you!

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

Because we must run all the steps from this tutorial with root privileges, we can either prepend all commands in this tutorial

This tutorial provides step-by-step instructions on how to install VMware Server 2 on a Mandriva 2009.0 desktop system. 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).

Also, with VMware Server you can let your old Windows desktop (that you previously converted into a VMware virtual machine with VMware Converter, as d
