Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on SuSE systems. It describes how to build a custom kernel using the latest unmodified kernel sources from http://www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

This tutorial describes how to install a Linux print server with CUPS. It also covers the installation and configuration of printer drivers on the print server as well as the printer setup on a Windows 2000 client.

This tutorial shows how to set up a Ubuntu 6.10 server (Edgy Eft) as a firewall and gateway for small/medium networks. The article covers the installation/configuration of services such as Shorewall, NAT, caching nameserver, DHCP server, VPN server, Webmin, Munin, Apache, Squirrelmail, Postfix, Courier IMAP and POP3, SpamAssassin, ClamAV, and many more.

This tutorial shows how to set up network-address-translation (NAT) on a Linux system with iptables rules so that the system can act as a gateway and provide internet access to multiple hosts on a local network using a single public IP address. This is achieved by rewriting the source and/or destination addresses of IP packets as they pass through the NAT system.

ASSP stands for Anti-Spam SMTP Proxy. The ASSP server project is an Open Source platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify spam. In short ASSP is the most kickass solution that is both free and works great. It reduced spam to an absolute minimum for me.

Racoon Roadwarrior is a client that uses unknown, dynamically assigned IP addresses to connect to a VPN gateway (in this case also firewall). This is one of the most interesting and today most needed scenarios in business environment. This tutorial shows how to configure Racoon Roadwarrior.

BixData is a system, application, and network monitoring tool which allows you to easily monitor nearly every aspect of your servers. The newly released version 2.6 is the only application that has the ability to control both Xen and VMware virtual machines. You can control both VM Hosts (the computer that's running the VM software) and VM Guests (the virtual machines running on the hosts).

Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Fedora systems. It describes how to build a custom kernel using the latest unmodified kernel sources from http://www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

This article describes how to prepare a CentOS 4.4 server for OpenVZ virtual machines. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers.

Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Ubuntu systems. It describes how to build a custom kernel using the latest unmodified kernel sources from http://www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

This guide describes how to install and use xen-tools, xen-shell, and Argo on a Debian system. All three packages provide useful tools for the administration of virtual Xen machines. Xen-tools is a collection of Perl scripts that allow you to easily create, update, and delete Xen guest domains. The xen-shell provides a command-line interface to owners of Xen domains so that they can manage their Xen domains without the help of the server administrator. And with Argo, you can control Xen domains through a web interface or through a menu on the command line.

This tutorial provides step-by-step instructions on how to install the free VMware Server (version 1.0.1) on a Debian Sarge 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. In this article we use Debian Sarge (3.1) as the host operating system.

This is a detailed description about how to set up a Ubuntu 6.10 (Edgy Eft) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.

This is a detailed description about how to set up a Fedora Core 6 based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.

Templates make life easier when you use them for letters, documents, brochures, etc. but they really make life easier when you use them for labels. This article is about how to use the OpenOffice.org templates, in particular the WorldLabel templates, to print the labels you need. It shows how to download them, install them, use them as they are, and how to customize them with graphics and other features. It also shows how to use the OpenOffice.org label wizard; you can use the label wizard each time, or save the template you create in the same template repository with your WorldLabel templates.

This tutorial provides step-by-step instructions about how to install Xen (version 3.0.3) on a Debian Sarge (3.1) system. It shows how to compile Xen, dom0 and domU kernels from the sources as well as how to install Xen from precompiled binaries. Creating guest domains from images is also covered by this article.

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.

This is a detailed description about how to set up a Mandriva 2007 Free Edition based server that offers all services needed by ISPs and hosters (Apache web server (SSL-capable), Postfix mail server (with SMTP-AUTH and TLS), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.).

This is a detailed description about how to set up a CentOS 4.4 based server that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.). This tutorial is written for the 32-bit version of CentOS 4.4, but should apply to the 64-bit version with very little modifications as well.

This tutorial describes how to set up MySQL master-master replication. We need to replicate MySQL servers to achieve high-availability (HA). In my case I need two masters that are synchronized with each other so that if one of them drops down, other could take over and no data is lost. Similarly when the first one goes up again, it will still be used as slave for the live one.
