nginx [engine x] is a HTTP server and mail proxy server

Using NTP is a great way to keep your system clock set correctly. It works by contacting a number of servers around the world, asking them for the time and then calculating what the correct local time is from their responses.

How DNS load balancing works When the request comes to the DNS server to resolve the domain name, it gives out one of the several canonical names in a rotated order. This redirects the request to one of the several servers in a server group. Once the BIND feature of DNS resolves the domain to one of the servers, subsequent requests from the same client are sent to the same server.

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 HOWTO enables you to build a complete open source turn-key email server in a matter of hours (instead of days or weeks). In one sense it is more like one big script that requires intervention. It can be considered a howto if one reads the contents of each patch and script I provide.

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.

FileTreePanel is client-server application where client (browser) provides the user interface (UI) which displays the tree and context menu, handles drag & drop operations, etc. The filesystem that is displayed and managed by the UI is stored on a server. Therefore, we need some communication layer between client and server. Client sends a command to server, server processes this command and responds with a result. Client in turn processes the response and display results. All this communication is running in the background by Ajax (XMLHttpRequest) calls. The XMLHttpRequest is not used directly but the Ext JS - JavaScript Library ajax layer is used for this purpose. Client requests data from server with standard POST method and server is expected to respond with JSON (JavaScript Object Notation) string and appropriate HTTP headers.

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

Dans la série des VMware Server 1.xx sur Ubuntu x.xx voila la mise à jour de la procédure d'installation de VMware Server 1.02 sur Ubuntu 7.04. Et la ça ce corse un peu, car comme le souligne The_Glu dans ce billet, le noyau 2.6.20 n'aime pas VMware. Et pour "pas gacher" les "bug httpd.vmware" et "ralentissement réseaux" sont toujours présents.

RSYNC Backup front-end with Web Interface, email reports with attached summary. Simple to use; back up servers with a single line, or your entire server farm from a single machine. Custom email tags sort responses in your MUA. Supports authentication.

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.
