How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

Post date: March 8, 2009, 13:03 Category: Installing Views: 3902 Comments
Tutorial quote: This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel.

User-Mode Linux

Post date: December 8, 2005, 13:12 Category: Software Views: 3733 Comments
Tutorial quote: One of the largest efforts involved with software engineering is testing the software to make sure that it works as designed. Testing can require several different types of system configurations and could require multiple instances of Linux. One way to create this type of environment is to use a virtual machine.

User-Mode Linux (UML) is a fully functional Linux kernel. It runs its own scheduler and virtual memory (VM) system, relying on the host kernel for hardware support. It includes virtual block, network, and serial devices to provide an environment that is almost as full-featured as a hardware-based machine. UML cannot destroy the host machine. Furthermore, the UML block devices, also called disks, can be files on the native Linux file system, so you cannot affect the native block devices. This is very useful when you're testing and debugging block operations.

Monitoring all filesystem modifications

Post date: April 12, 2005, 07:04 Category: Security Views: 3590 Comments
Tutorial quote: After loading this kernel module you can monitor all file system alterations by simply typing: cat /dev/fsysmon

It's original purpose was to feed a daemon with data but nevertheless I found it to be even more useful as a standalone project.

Configuring Apache for Maximum Performance

Post date: February 12, 2006, 09:02 Category: Optimizing Views: 3792 Comments
Tutorial quote: Apache is an open-source HTTP server implementation. It is the most popular web server on the Internet; the December 2005 Web Server Survey conducted by Netcraft [1] shows that about 70% of the web sites on Internet are using Apache.

Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU, etc. But most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on Linux systems. Of course, it is assumed that there is enough hardware resources - especially enough RAM that the server isn't swapping frequently. First two sections look into various Compile-Time and Run-Time configuration options. The Run-Time section assumes that Apache is compiled with prefork MPM. HTTP compression and caching is discussed next. Finally, using separate servers for serving static and dynamic contents is covered. Basic knowledge of compiling and configuring Apache and Linux are assumed.

DOS Emulation Under Linux

Post date: May 1, 2005, 17:05 Category: Emulation Views: 3099 Comments
Tutorial quote: Whether you need to run some legacy corporate application, or just want to play some of those old classic DOS games, it's easy to get going.

I've done this on a Slackware 9.1 Linux system with a 2.4.22 kernel, running KDE 3.1.4. The process should be very similar for most reasonably recent Linux distros.

Tunneling the hard way: using slirp, pppd and socat

Post date: January 29, 2006, 13:01 Category: Network Views: 11224 Comments
Tutorial quote: Every now and then you might come across a "bad" ISP. The one I have at home for example is dropping UDP packets ever so often when I try to play online games -- and it tends to drop random packets while I try to log onto a gameserver too which makes a certain game I like to play crash during the loading phase so it can't recover. I also heard of other ISPs blocking certain ports on external servers -- universities for example seem to like blocking p2p network ports and the school i was attending till last august blocked everything but port 80 for http -- including ftp which made even on-topic "research" a pita at times.
Usually there's three ways of working around this problem if "giving up" is not an option to you: a) change your ISP, b) use ssh to redirect ports, c) connect to an external VPN to route for you. a) can be tricky -- it's impossible if you're sharing the link with your parents and they insist on their email addresses or in the university/workplace/school scenario. b) will only work with single port/host combinations and for c) you will need a full-fledged rootbox idling around on the internet -- which tend to be expensive and "virtual servers" might not work because those often don't include tun/tap devices and/or kernel-level ppp support if you rent them and in case you rented them you probably can't fiddle around with its kernel to enable it (that was my problem at least). If any of this rings a bell to you, read on and discover method d)
