It is an alternative to the plain-text password files provided by mod_auth and allows you to use normal SQL syntax to create/modify delete users. You can also configure mod_auth_mysql to authenticate against an existing MySQL user table. falko Tue, 15 Nov 2011 10:31:33 GMT http://www.howtoforge.com/how-to-patch-bind-to-avoid-cache-poisoning-debian-etch Dan Kaminsky earlier this month announced a massive, multi-vendor issue with DNS that could allow attackers to compromise any name server - clients, too. These two articles explain how you can fix a BIND9 nameserver on Debian Etch and Fedora/CentOS so that it is not vulnerable anymore to DNS cache poisoning. falko Tue, 29 Jul 2008 09:55:44 GMT http://www.howtoforge.com/how-to-run-fully-virtualized-guests-hvm-with-xen-3.2-on-debian-lenny-x86_64 This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel. falko Sun, 08 Mar 2009 13:39:04 GMT http://www.howtoforge.com/how-to-run-your-own-dns-servers-primary-and-secondary-with-ispconfig-3-debian-squeeze This tutorial shows how you can run your own DNS servers (primary and secondary) with ISPConfig 3. To do this, you need two servers with two different public IP addresses and with ISPConfig 3 installed. I will use Debian Squeeze for both DNS servers here to demonstrate the base system setup process and ISPConfig 3 installation, but once you have ISPConfig 3 installed on your servers, the configuration inside ISPConfig 3 is identical, no matter what distribution you use. falko Thu, 21 Jul 2011 10:21:10 GMT http://www.howtoforge.com/how-to-save-traffic-with-lighttpds-mod_compress-debian-squeeze In this tutorial I will describe how to configure mod_compress on a Lighttpd web server (on Debian Squeeze). mod_compress allows Lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_compress, you can compress HTML, CSS, Javascript, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier. falko Thu, 07 Apr 2011 10:54:44 GMT http://www.howtoforge.com/lighttpd_1.4_mod_deflate_debian_etch In this tutorial I will describe how to install and configure mod_deflate on a lighttpd 1.4 web server on Debian Etch. mod_deflate is included by default in lighttpd 1.5, but not in 1.4 where mod_compress is used instead. The advantage of mod_deflate over mod_compress is that it can compress static and dynamic files (such as PHP files), whereas mod_compress can compress static files only. The lighttpd version coming with Debian Etch is 1.4.13, so we have to patch it to support mod_deflate. mod_deflate allows lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving falko Fri, 17 Aug 2007 09:04:21 GMT http://www.howtoforge.com/how-to-set-up-a-caching-reverse-proxy-with-squid-2.6-on-debian-etch This article explains how you can set up a caching reverse proxy with Squid 2.6 in front of your web server on Debian Etch. If you have a high-traffic dynamic web site that generates lots of database queries on each request, you can decrease the server load dramatically by caching your content for a few minutes or more (that depends on how often you update your content). falko Sun, 28 Dec 2008 10:57:37 GMT http://www.howtoforge.com/setting-up-a-loadbalanced-mysql-cluster-with-mysql5.1 This tutorial shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster). falko Tue, 17 Jun 2008 09:52:40 GMT http://www.howtoforge.com/how-to-set-up-a-usb-over-ip-server-and-client-with-debian-lenny This tutorial shows how to set up a USB-over-IP server with Debian Lenny as well as a USB-over-IP client (also running Debian Lenny). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices. falko Sun, 24 Jan 2010 01:37:55 GMT http://www.howtoforge.com/how-to-set-up-an-ssl-vhost-under-apache2-on-ubuntu-9.10-debian-lenny This article explains how you can set up an SSL vhost under Apache2 on Ubuntu 9.10 and Debian Lenny so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end. We use the mod_ssl Apache module here to provide strong cryptography for Apache2 via SSL by the help of the Open Source SSL toolkit OpenSSL. falko Thu, 21 Jan 2010 13:42:07 GMT
