Routing mail messages to your mailserver efficiently

Post date: May 12, 2006, 12:05 Category: Network Views: 3878 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: 5050 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.

screen: Keep Your Processes Running Despite A Dropped Connection

Post date: December 12, 2006, 20:12 Category: System Views: 3433 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.

Monitoring your hardware's temperature

Post date: January 5, 2006, 09:01 Category: Software Views: 3304 Comments
Tutorial quote: Sometimes it is useful to know the temperature of your hardware, to prevent it from frying. This information can easily be found, if your hardware provides the sensors needed, and we have the necessary software.

Most computers come with temperature sensors, which can be used to prevent your hardware from excessive heat. The most important thing to watch is, of course, your CPU temperature. This is where lm-sensors comes in.

VLC is also multiplatform in the most extreme sense of the word; it can run on Windows, OSX, Linux and PocketPC / WinCE handhelds along with other systems. VLC works great as a streaming server and video transcoder too.

shred - Securely delete files in Linux

Post date: January 24, 2010, 06:01 Category: Security Views: 5121 Comments
Tutorial quote: In case you want to delete some confidential data from your computer just to make sure that it is no longer accessible to anyone, then do not delete the file using the regular rm command because there will still remain a chance that someone might use a software to recover your deleted data before the specific storage area is overwritten by new data. The proper way to permanently dispose of such data in Linux is the shred command.
