Fixing open DNS servers

Ok, there seems to be a *lot* of posts and threads about this issue and I think a simple page is appropriate.

Lets start with the problem. Check the report for your domain here: http://www.dnsreport.com/tools/dnsreport.ch?domain=YOUR_DOMAIN_HERE.COM

An open DNS server is one that replies to a query about a domain it is not responsible for, to anyone who asks for it. For starters, that is just a waste of processing time, but it can be worse if it is used for flooding. See, since a DNS query is (much!) smaller in number of bytes than a DNS response, if it is spoofed it can be used to perform a DoS attack on a computer with several times the bandwidth of the perpretator.

I’ve posted a solution to my obscure cPanel guide, have a look if your interested:

GNU Radio: hacking the last frontier

Imagine a combination of hardware and software that could receive and transmit at any frequency.

Imagine you could have an FM radio that turns into a GPS receiver that turns into a RFID reader. Or a Radar. Or a Digital TV Receiver. Or a mobile phone. Or a Wi-Fi scanner. All at the click of a button.

Imagine the political, social and economic consequences.

Welcome to GNU Radio: the last frontier where hacking can be found in its true form.

Note: not for the faint of heart.

Linux: What you should have on your Ubuntu lady

This is my attempt to put together what I consider the “essentials” if you’re new to Ubuntu and/or don’t have time to scout around for all those things everyone is talking about but you haven’t got the faintest clue (like what the hell is “glxgears” and why is it *not* a benchmark and why you should still check those results!)

Quick and dirty:

EasyUbuntu 2.3 (for “breezy” a.k.a. 5.10):

Easy Ubuntu allow you to:

* Add extra repositories for installing a lot of additional software.
* Install multimedia codecs for reading all videos, musics and DVDs.
* Activate the “audio preview” feature in Nautilus.
* Install the most needed Firefox plugins: Flash, Java, Real, videos. Adds Microsoft fonts, GNOME’s Firefox buttons, officials Firefox icons.
* Install archiving support for RAR and ACE.
* Install the most used peer-to-peer softwares: aMule (a clone of eMule) and Azureus (for Bittorent).
* Install the Skype voice-over-IP software. (Warning: at this time Skype is not packaged for Breezy so install don’t work)
* MSN: Install AMSN cvs with webcam support.
* Num lock: Active the num lock at system startup.
* Replace the GNOME foot logo with Ubuntu’s logo.
* Install the NVIDIA or ATI driver for 3D support.

Follow instructions on how to make it run under linux.

Essentials:

nwnmouse (enables hardware mouse acceleration under linux)

if you happen to have an ATI card and you find your memory usage going up and up and up to the point where your game starts getting very slow and/or nwn simply exits, you probably have a memory leak problem. Read this:

There’s an entire thread on ubuntuforums.com about glxgears ‘scores’ (http://www.ubuntuforums.org/showthread.php?t=39349)

On average, my ATI Radeon 9000 gets 2000 FPS with glx gears.

skyhorse@skybuntu:~$ glxgears -iacknowledgethatthistoolisnotabenchmark
10291 frames in 5.0 seconds = 2058.139 FPS
10262 frames in 5.0 seconds = 2052.398 FPS
10260 frames in 5.0 seconds = 2051.876 FPS
10220 frames in 5.0 seconds = 2043.961 FPS
