How to scan your Linux-Distro for Root Kits

Post date: May 19, 2006, 18:05 Category: Security Views: 3243 Comments
Tutorial quote: Do you suspect that you have a compromised system ?
Check now for root kits that the intruder may have installed !!!

So... What in the hell is a root kit ???
A root kit is a collection of programs that intruders often install after they have compromised the root account of a system.
These programs will help the intruders clean up their tracks, as well as provide access back into the system.
Root kits will sometimes leave processes running so that the intruder can come back easily and without the system administrator's knowledge !

Solution....
Scripts like chkrootkit will do the job for you automatically.

Making Web Browsing Easy For The Tiny Screen

Post date: August 9, 2005, 19:08 Category: Network Views: 2823 Comments
Tutorial quote: An avalanche of content will soon appear in the palm of your hand.

Tiny screens are showing up everywhere in PDAs and cell phones. Many are equipped with some form of network device and a browser, so it's not hard to see what's coming down the pike.

Late model PDAs, like my HP iPAQ 3715 no longer suffer from insufficient computing power, lack of memory or having to rely on pricey external 802.11b cards. The little machine is quick to boot up and can handle many daily business functions.

Even though it runs a version of Internet Explorer, jumping onto an access point and browsing web pages is fast and useful.

In this edition, I'll share my observations on things you might consider when converting LAMP (Linux, Apache, MySQL, PHP) applications or web pages, for use on the tiny screen. I'll approach the issues from an iPAQ user perspective and focus on convenience and making the user's life easy.

Tutorial quote: For desktop and laptop users who want a fast-booting operating system, getting rid of services you do not need can appear to improve performance. Obviously, if you are new to Linux, though, you probably do not know which processes you can get rid of safely nor how to stop them and keep them from restarting at boot time.

The lost art of named pipes

Post date: April 15, 2005, 21:04 Category: System Views: 2841 Comments
Tutorial quote: A "named pipe" -- also known as a FIFO (First In, First Out) or just fifo -- is an inter-process communication mechanism that makes use of the filesystem to allow two processes to communicate with each other. In particular, it allows one of these to open one end of the pipe as a reader, and the other to open it as a writer. Let's take a look at the FIFO and how you can use it.
