  • Story Type: Tutorial; Groups: Linux
This document describes how to attach modems to a Linux box and allow it to receive calls to connect users to the network. It is like being your own ISP (Internet Service Provider). If your Linux box is connected to the Internet, then the users will also be connected to the Internet. Your Linux box becomes a router. This is also known as RAS (Remote Access Services) in the Microsoft world. In the Linux world it is called PPP (Point to Point Protocol).

  • Story Type: Tutorial; Groups: Linux
This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.

Automatically Scan Uploaded Files For Viruses With php-clamavlib

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.

Normally Linux systems can only read from Windows NTFS partitions, but not write to them which can be very annoying if you have to work with Linux and Windows systems. This is where ntfs-3g comes into play. ntfs-3g is an open source, freely available NTFS driver for Linux with read and write support. This tutorial shows how to install and use ntfs-3g on an Ubuntu Edgy Eft desktop to read from and write to Windows NTFS drives and partitions. It covers the usage of internal NTFS partitions (e.g. in a dual-boot environment) and of external USB NTFS drives.

OpenVZ On Debian Etch For Webservers

  • HowtoForge; By Cies Breijs (Posted by falko on Dec 26, 2006 6:32 AM EDT)
  • Story Type: Tutorial; Groups: Debian
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.

How To Compile A Kernel - The Debian (Sarge) Way

Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Debian Sarge 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.

Setting Up A PXE Install Server For Multiple Linux Distributions With Ubuntu Edgy Eft

  • HowtoForge; By Falko Timme (Posted by falko on Dec 19, 2006 9:41 PM EDT)
  • Story Type: Tutorial; Groups: Ubuntu
This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 6.10 (Edgy Eft). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions: Ubuntu Edgy/Dapper, Debian Etch/Sarge, Fedora Core 6, CentOS 4.4, OpenSuSE 10.2, and Mandriva 2007.

The Perfect Setup - OpenSuSE 10.2

  • HowtoForge; By Falko Timme (Posted by falko on Dec 17, 2006 5:16 PM EDT)
  • Story Type: Tutorial; Groups: SUSE
This is a detailed description about how to set up an OpenSuSE 10.2 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 server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc.).

screen: Keep Your Processes Running Despite A Dropped Connection

  • HowtoForge; By Falko Timme (Posted by falko on Dec 12, 2006 11:56 AM EDT)
  • Story Type: Tutorial; Groups: Linux
I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose.

Key-Based SSH Logins With PuTTY

  • HowtoForge; By Falko Timme (Posted by falko on Dec 10, 2006 7:49 AM EDT)
  • Story Type: Tutorial; Groups: Linux
This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure.

Postfix with dkfilter (DomainKeys Implementation)

  • HowtoForge; By Sohail Riaz (Posted by falko on Dec 7, 2006 3:49 PM EDT)

It implements DomainKeys message signing and verification. It comprises two separate filters, an outbound filter for signing outgoing email on port 587, and an inbound filter for verifying signatures of incoming email on port 25. This document shows step-by-step how to install dkfilter for Postfix to deploy DomainKeys signing and verification.

Installing Popular Applications On Your Ubuntu Desktop With Automatix2

  • HowtoForge; By Falko Timme (Posted by falko on Dec 5, 2006 11:10 AM EDT)
  • Story Type: Tutorial; Groups: Ubuntu
Although Ubuntu comes with lots of applications that can be installed on your desktop, there are still some applications that are available only from third-party repositories. Finding all these repositories and installing these applications manually is very time-consuming, but fortunately some people have created a script called Automatix2 (which is the successor to Automatix) which automates the task for you. It comes with a graphical interface so that you can run it from your desktop, and this tutorial describes how you do it.
