Post date: July 5, 2005, 06:07 Category: Network Views: 3841 Comments
Tutorial quote: Given the sheer importance of name servers in providing Domain Name System (DNS) resolution -- a process used by every Web-facing application to translate domain names into IP addresses and vice versa -- not many people put much thought into the available software alternatives for pulling off this feat. One compelling application is NSD, an alternative to the widely deployed BIND name server.

Routing mail messages to your mailserver efficiently

Post date: May 12, 2006, 12:05 Category: Network Views: 4020 Comments
Tutorial quote: If you control satellite systems which need to relay their mail through a centralized host for sending then you have several choices. Perhaps the simplest software to use is the nullmailer program.

In the past we've looked at setting up exim, postfix, and sendmail forwarding but if you're not expecting to send much mail, and you don't need much processing then running a full mailserver is probably overkill.

The nullmailer package is very simple to configure and install.

Emulating an OS with qemu

Post date: May 22, 2005, 08:05 Category: Emulation Views: 5190 Comments
Tutorial quote: When you want to emulate a PC with a complete operating system on your computer, the most heard answer would be VMWare. Sure, for Linux, there is wine, but that package is targeted to handle only window$ and not all programs are supported. No, I'm talking about simulating a complete OS on a virtual PC with virtual hardware.

Although VMware does an almost perfect job at it, it isn't free software. Time to see what the Open Source community has to offer. That's when I stumbled upon qemu. Let's have a look at the possibilities.

Post date: December 12, 2006, 20:12 Category: System Views: 3574 Comments
Tutorial quote: 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.
