How To Install A Debian Based Distro On An EasySpeedy Server
The following tutorial is a detailed description of how to install a Debian based distro (Debian Etch in this example) on an EasySpeedy server. EasySpeedy offers dedicated server hosting with the ability for customers to perform remote recovery and maintenance over ssh. This is exactly what we need to install our debian based distro from scratch, using debootstrap.
How To Install VMware Server On A Fedora Core 6 Desktop
This tutorial provides step-by-step instructions on how to install VMware Server on a Fedora Core 6 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).
Installing The Aptana AJAX Development Environment On Ubuntu
Useful Commands For The Linux Command Line
This short guide shows some important commands for your daily work on the Linux command line.
MyDNS with MyDNSConfig Control Panel and DNSMasq on Ubuntu 6.10
In this tutorial I will describe how to install and configure MyDNS and MyDNSConfig. MyDNS is a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. The advantage is that MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted. A secondary nameserver can be easily set up by installing a second instance of MyDNS that accesses the same database or, to be more redundant, uses the MySQL master / slave replication features to replicate the data to the secondary nameserver.
How To Install Zimbra Collaboration Suite (ZCS) On Ubuntu
This guide shows how to install the Zimbra Collaboration Suite (ZCS) on Ubuntu 6.10 (Edgy Eft) and 6.06 (Dapper Drake) server systems. Zimbra is a full-featured, open source collaboration suite - email, group calendaring, contacts, and web document management and authoring. It has a feature-rich AJAX web interface and is compatible with clients such as Microsoft Outlook, Apple Mail, and Novell Evolution so that mail, contacts, and calendar items can be synchronised from these to the ZCS server. It can also be synchronized to many mobile devices. ZCS makes use of many existing open source projects such as Postfix, MySQL, and OpenLDAP.
Creating a dd/dcfldd Image Using Automated Image & Restore (AIR)
Automated Image & Restore (AIR) is an open source application that provides a GUI front end to the dd/dcfldd (Dataset Definition (dd)) command. AIR is designed to easily create forensic disk/partition images. It supports MD5/SHAx hashes, SCSI tape drives, imaging over a TCP/IP network, splitting images, and detailed session logging. To date, the AIR utility has only been developed for use on Linux distributions. In its simplest form, AIR provides a convenient interface to execute the dd set of commands. It eliminates the risk of "fat fingering" an error in the shell terminal and ultimately makes using the dd command more user-friendly for those who are not as experienced. Please note that using the AIR front end still requires some basic knowledge of how the dd (or dcfldd) commands work.
The Perfect Desktop - Part 3: Ubuntu 6.10 Edgy Eft
With the release of Microsoft's new Windows operating system (Vista), more and more people are looking for alternatives to Windows for various reasons. This tutorial is the third in a series of articles where I will show people who are willing to switch to Linux how they can set up a Linux desktop (Ubuntu 6.10 Edgy Eft in this article) that fully replaces their Windows desktop, i.e. that has all software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that runs also on older hardware, and the best thing is: all software comes free of charge.
Setting the SUID/SGID bits: Giving a program YOUR permissions when it runs
Normally, when a program runs under Linux, it inherits the permissions of the user who is running it, thus if I run a program under my account, the program runs with the same permissions that I would have if that program were me. Thus, if I cannot open a certain file, the program I am running also cannot open the file in question. If I set the SUID or SGID bit for a file, this causes any persons or processes that run the file to have access to system resources as though they are the owner of the file.
