Running ISPConfig On Port 80 Using Apache's Reverse Proxy Feature (Debian Etch)
This article shows how you can configure a Debian Etch system that has the webhosting control panel ISPConfig installed so that ISPConfig can be accessed on port 80. By default ISPConfig uses port 81 which is a non-standard port and is blocked by some firewalls and ISPs. By using Apache's mod_proxy module, we can avoid this problem. It lets us create a reverse proxy that can fetch the pages from ISPConfig on port 81.
The Perfect Server - Mandriva 2007 Spring Free (Mandriva 2007.1)
This is a detailed description about how to set up a Mandriva 2007 Spring Free 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 Mandriva 2007 Spring, but should apply to the 64-bit version with very little modifications as well.
How to secure VNC remote access with two-factor authentication
VNC is the most popular remote access solution today. However, it was developed to provide remote access, not to provide secure remote access. Administrators have to add security to VNC by tunneling it through an encrpyted channel such as SSH and adding a layer of authentication. In this article, we will show you how to combine the NoMachine NX server to encrpyt VNC and remote X session combined with two-factor authentication from WiKID Systems to create a secure, fast remote access solution.
Beryl, Compiz, And Metisse - The 3D Desktop on Mandriva Linux 2007 Spring
After having included the AIGLX, Xgl and Compiz 3D desktop technologies in Mandriva Linux 2007, Mandriva has added all the latest 3D desktop updates in Mandriva Linux 2007 Spring, like Metisse and Beryl.
QoS And Traffic Shaping For VoIP Users Using iproute2 And Asterisk
The quality of my VoIP phone calls suffered whenever I was downloading or uploading anything. This was irritating, especially for those calling me (I heard them better than they heard me). So I poked at Iproute2 and other howtos, especially with regard to VoIP traffic, but I couldn't find anything that worked well. After some playing around, I've found settings that were right for me: consistant VoIP quality, regardless of any activities on the wire.
How To Install VMware Server On A CentOS 5.0 Desktop
This tutorial provides step-by-step instructions on how to install VMware Server on a CentOS 5.0 desktop 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. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).
Secure Websites Using SSL And Certificates
This how-to will guide you through the entire process of setting up a secure website using SSL and digital certificates. This guide assumes that you have already a fully functional (and configured) server running Apache, BIND, and OpenSSL. Just as a side note, this guide was written based on a Fedora Core 6 distribution, but should be the same for most other distros out there.
The Perfect Desktop - Ubuntu Studio 7.04
Ubuntu Studio is a special Linux distribution tailored to the needs of audio, video, and graphic enthusiasts or professionals. Because Ubuntu Studio is based on Ubuntu, you are not limited to this area, but can install any application that is available for Ubuntu, thus turning Ubuntu Studio in a normal desktop for everyday use. This tutorial shows how you can turn Ubuntu Studio 7.04 into a full-fledged replacement for a Windows desktop. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.
A Guide to Virtualization on Mandriva Linux 2007 Spring
Have you ever wished you had another computer handy? Maybe you want to try a new operating system out. Maybe you want to test something experimental without potentially breaking your own system. Maybe you need to run some software that only runs in a different operating system. Mandriva Linux 2007 Spring comes with a range of virtualization options that can help.
Server Monitoring With munin And monit On Debian Etch
In this article I will describe how you can monitor your Debian Etch server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that let you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
