How To Set Up VMware Tools On Various Linux Distributions

Post date: October 2, 2007, 07:10 Category: Miscellaneous Views: 9026 Comments
Tutorial quote: This document explains how to set up the VMware Tools in the following guest operating systems: Ubuntu 7.04, Fedora 7, PCLinuxOS 2007 and Debian Etch. Installing VMware Tools in your guest operating systems will help maximize performance, provide mouse synchronization and copy & paste functionality. This article also shows a way of making VMware Tools start automatically when you start a guest operating system.

Create a LAN for Virtual Servers with KVM and VDE

Post date: November 11, 2008, 19:11 Category: System Views: 4621 Comments
Tutorial quote: You have one host [ hoster ] running KVM on UBUNTU with 1 network interface accessing to internet.You want to have 2 debian etch virtual servers [ guest ] ( debian01 and debian02 ) running on your hoster with network access between them and hoster in a local LAN. In this case virtual servers will not be able to access to internet, but later I will explain how to do it.

Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)

Post date: June 5, 2007, 23:06 Category: Installing Views: 3670 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

Setting Up Master-Master Replication With MySQL 5 On Debian Etch

Post date: October 25, 2007, 11:10 Category: Miscellaneous Views: 3872 Comments
Tutorial quote: Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

Automatically Scan Uploaded Files For Viruses With php-clamavlib

Post date: January 14, 2007, 21:01 Category: Security Views: 5336 Comments
Tutorial quote: This guide describes how you can automatically scan files uploaded by users through a web form on your server using PHP and ClamAV. That way you can make sure that your upload form will not be abused to distribute malware. To glue PHP and ClamAV, we install the package php5-clamavlib/php4-clamavlib which is rather undocumented at this time. That package is available for Debian Etch and Sid and also for Ubuntu Dapper Drake and Edgy Eft.

Getting started with RHEL4's built-in LVM tools

Post date: June 3, 2005, 16:06 Category: System Views: 6911 Comments
Tutorial quote: Many Unix administrators I know (you know who you are), always used to smirk when I talked about Linux. They could always point to the fact that regardless of whatever I could say, they had journaling file systems, which they could manage using various Logical Volume Management (LVM) tools, and I couldn't touch that.

Well, not any more! Not only does Red Hat offer ext3 as their default file system, but they offer great management tools to boot. As we know, ext2 had a great lifespan, but it was not an enterprise-ready file system that could handle large disk partitions, fast recovery from systems crashes, or large amounts of files. Journaling file systems give you the ability to recover almost instantly from a crash, as you do not need to run fsck after a restart. Similar to how databases recover from crashes, a journaling file system tracks changes to file system metadata and pretty much guarantees that either all or no updates have completed. Of course, these file systems also need elaborate tools to help better configure and manage them accordingly.

OpenVZ On Debian Etch For Webservers

Post date: December 26, 2006, 21:12 Category: System Views: 4131 Comments
Tutorial quote: Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch

Post date: December 18, 2007, 12:12 Category: Miscellaneous Views: 4170 Comments
Tutorial quote: When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

Benchmarking Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3785 Comments
Tutorial quote: I recently purchased a Western Digital 250GB/8M/7200RPM drive and wondered which journaling file system I should use. I currently use ext2 on my other, smaller hard drives. Upon reboot or unclean shutdown, e2fsck takes a while on drives only 40 and 60 gigabytes. Therefore I knew using a journaling file system would be my best bet. The question is: which is the best? In order to determine this I used common operations that Linux users may perform on a regular basis instead of using benchmark tools such as Bonnie or Iozone. I wanted a "real life" benchmark analysis. A quick analogy: Just because the Ethernet-Over-Power-Lines may advertise 10mbps (1.25MB/s), in real world tests, peak speed is only 5mbps (625KB/s). This is why I chose to run my own tests versus using hard drive benchmarking tools.
