This document is a step by step guide for configuring Ubuntu 7.10 as a Samba Domain Controller with an LDAP backend (OpenLDAP). The point is to configure a server that can be comparable, from a central authentication point of view, to a Windows Server 2003 Domain Controller. The end result will be a server with an LDAP directory for storing user, group, and computer accounts. A Windows XP Professional SP2 workstation will be able to join the domain once properly configured. Please note that you do not have a fully comparable Windows domain controller at this time. Do not kid yourself, this guide only gets you a server with LDAP authentication. Of course this can be expanded to include slave servers to spread out authentication over multiple networks. Please also note that it took me approximately two and a half weeks to compile this information and get it working. The same functionality can be had in Windows in less than four hours (and this includes operating system installation). In my humble opinion the open source community will need to work on this side of Linux in order for it to be a true alternative to Windows.

If you have a server with more than 4GB RAM and want to install a 32bit Debian Etch on it (following this tutorial: Debian Etch And Xen From The Debian Repository), you'd expect the Xen-PAE kernel to see all your RAM because the Xen-PAE kernel supports up to 64GB RAM. In fact, it recognizes only about 3.3GB RAM due to a bug in the GRUB bootloader. This article explains how you can fix GRUB so that all your RAM gets recognized. I do not issue any guarantee that this will work for you!

Pound is a reverse-proxy load balancing server. It accepts requests from HTTP / HTTPS clients and distributes them to one or more Web servers. The HTTPS requests are decrypted and passed to the back-ends as plain HTTP. It will act as: a) Server load balancer b) Reverse proxy server c) Apache reverse proxy etc d) It can detects when a backend server fails or recovers, and bases its load balancing decisions on this information: if a backend server fails, it will not receive requests until it recovers e) It can decrypts https requests to http ones f) Rejects incorrect requests h) It can be used in a chroot environment (security feature)

This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch). I was asked to design a secure, scalable, portable solution for a small company. While the guide references many 'servers', the company only had 4 physical machines, Xen was used to virtualize the entire solution. That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.

Vmware server comes with the nifty vmware-cmd utility. It allows an administrator to perform various operations on a virtual machine from Linux command line / shell prompt such as: => Stop / Start VM => Get VM status => Setup variables => Powerdown VM and much more

This document describes how to integrate ASSP (Anti-Spam SMTP Proxy) with embedded ClamAV into a mail server based on Postfix featuring virtual users and domains, i.e. users and domains that are in a MySQL database.

This tutorial provides step-by-step instructions about how to create a highly available VMware Server environment on a Debian Etch system. With this tutorial, you will be able to create Virtual Machines that will be available on multiple systems with failover/failback capabilities.

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.

Applications using the LAMP (Linux®, Apache, MySQL, PHP/Perl) architecture are constantly being developed and deployed. But often the server administrator has little control over the application itself because it's written by someone else. This series of three articles discusses many of the server configuration items that can make or break an application's performance. This second article focuses on steps you can take to optimize Apache and PHP. Linux, Apache, MySQL, and PHP (or Perl) form the basis of the LAMP architecture for Web applications. Many open source packages based on LAMP components are available to solve a variety of problems. As the load on an application increases, the bottlenecks in the underlying infrastructure become more apparent in the form of slow response to user requests. The previous article showed you how to tune the Linux system and covered the basics of LAMP and performance measurement. This article focuses on the Web server components, Apache and PHP.

In this article I describe how to install and setup the Cacti in a ISPConfig Server. There aren't many differences from installing in other ISP Managers or standalone Apache installations. I tried many others solutions, but Cacti is very simple and fast to implement.

eBox management tool will effectively and easily help you managing the advanced services for your corporate network. Designed with extensibility in mind it offers, among others, these modules: Firewall, Transparent proxy, Content filter, NTP Server, Users and groups, Mail server

This tutorial shows how to set up a Debian Etch (Debian 4.0) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Debian Etch, but should apply to the 64-bit version with very little modifications as well.

Jon Peck: How to Configure an $80 File Server in 45 Minutes

What if there was a way to publish an application on the Linux desktop via a remote connection protocol like Remote Desktop Protocol? I know that this sounds an awful lot like Citrix and, in fact, what I am proposing is similar. However, Citrix is expensive and seems to be overkill for just a few network/security administrators' laptops or desktops. This recipe consists of a laptop/desktop running Linux in a GUI with VMware Server, a Windows XP VM and a product called 2X Application Server for Windows Terminal Services. Once you are done, you will have a Windows XP VM running as a service and loaded with any applications that you may need.

This is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there's nothing to do. On the client side mounting the filesystem is as easy as logging into the server with ssh. The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful. There were some limitations of that codebase, so I rewrote it. Features of this implementation are: * Based on FUSE (the best userspace filesystem framework for linux ;-) * Multithreading: more than one request can be on it's way to the server * Allowing large reads (max 64k) * Caching directory contents

This tutorial shows how to install and configure the Zenoss network monitoring tool on a Ubuntu 6.06 system. Zenoss is a free open-source tool that allows you to monitor servers, applications, networks, power, etc. regarding their configuration, availability, performance, and so on. It can also alert you by email if it finds inappropriate actions.

Free email server software with 9 users, 1 domain license (requires only a simple 1 minute registration). Email and messaging represent a must have for all companies, regardless their size or location, when we talk about business functions.

This article shows how to run a file-, print-, HTTP proxy- DHCP-, and time server for small and medium enterprises (SME) on one single Debian Sarge system. It is very easy to set up, and management is done with an easy-to-use web interface called eBox so once the system is set up, you can forget about the command line. eBox was developed to administrate advanced services for corporate networks, and it was created for Debian Sarge.

Ce document me sert de mémo pour installer et configurer « Linux Terminal Server (LTSP 4.2) » sur une Debian Testing. Ce système permet de recycler de vieux ordinateurs en terminaux graphiques. Pour cela, il faut un ordinateur assez puissant (qui fera office de serveur) et avec suffisamment de mémoire vive pour pouvoir gérer les terminaux. Les terminaux peuvent être, par exemple, des pentium 166 avec 32 Mo de mémoire vive et sans disque dur.
