Since a couple of days I've been hooked to incredible a free music discovery service, Pandora

Pandora is a music discovery service designed to help you find and enjoy music that you'll love. It's powered by the Music Genome Project, the most comprehensive analysis of music ever undertaken. Just tell us one of your favorite songs or artists and we'll launch a streaming station to explore that part of the music universe.

The songs are searched from a large database & are played directly from the browser,no need to install any software or plugins !!
The best part is registration is free,offers personalised playlists.So I take my favourite music where ever I go, virtually.

Hacking the Linksys WRT54G !

Friday, November 11, 2005

If you have ever had a taste of this little piece which runs on GNU/Linux you'll never want to buy any other brand/model thereafter.

If my above statement seems exaggeration then please have a look at the various options this router can incorporate itself with due it its "Open Source" nature.

The place where I work has 13 Linksys WRT54G's deployed by myself.Each running through Linksys WAPPOE [Power over Ethernet] adapter kit which is separately installed.
Although installing & configuring & making them work as Access Points[AP's] was a walk in the park,the biggest challenge was to make these AP's work in accordance to the network infrastructure already setup.The network was segmented into a number of VLAN's[Virtual LAN's].
For any version of the Linksys WRT54G,the default firmware doesnt support VLAN,QOS,WDS & a lot more entreprise features.

With a little searching I was onto a number of Open Source firmware's which supported the "extra" features I was looking for.The Alchemy firmware was the one which caught my eye cause of the "VLAN" feature exclusively needed for this setup.

With a little caution & study of flashing firmware all the 13 AP's have been setup with VLAN support & all of them are working like a charm.
IMHO the Linksys WRT54G is a pretty ordinary router out of the box when it comes to features as compared to the other brand competitors but due to its Open Source nature there is vast amount of flexibility which comes with it that puts it in a class of its own !

Sveasoft Firmware:The Sveasoft firmware is a replacement firmware upgrade for Linksys WRT54G or WRT54GS wireless routers. Our firmware adds dozens of sophisticated features to these sub-$100 routers turning them into the equivalent of products costing hundreds or thousands of dollars.

OpenWRT:OpenWrt is a Linux distribution for wireless routers. Instead of trying to cram every possible feature into one firmware, OpenWrt provides only a minimal firmware with support for add-on packages. For users this means the ability to custom tune features, removing unwanted packages to make room for other packages and for developers this means being able to focus on packages without having to test and release an entire firmware

DD-WRT:DD-WRT is a 100% free firmware for the Linksys WRT54G/GS and the Asus WL-500 deluxe 802.11g wireless routers (which run off a minimalist Linux OS).

Sony sells Rootkits too !

Wednesday, November 02, 2005
Last week when I was testing the latest version of RootkitRevealer (RKR) I ran a scan on one of my systems and was shocked to see evidence of a rootkit. Rootkits are cloaking technologies that hide files, Registry keys, and other system objects from diagnostic and security software, and they are usually employed by malware attempting to keep their implementation hidden (see my “Unearthing Rootkits” article from thre June issue of Windows IT Pro Magazine for more information on rootkits). The RKR results window reported a hidden directory, several hidden device drivers, and a hidden application:
