start -> run -> regedit
make a backup, if you want.
goto:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}

look through the list of subkeys (0000, 0001, etc)
DriverDesc keyword will tell you which network adapter. For example, “NVIDIA nForce Networking Controller”
when you find it, right click and add -> new -> string value

new keyword:

Value Name: = NetworkAddress
Value Data: = your new MAC, with no space or : For example, 0019DB71C830

then type:

ipconfig /release
ipconfig /renew
ipconfig /all   (to verify the new mac took)

Now your a l33t Winblows H4|<3r. If you want to go back to your hardware MAC, remove the NetworkAddress key and restart the interface.

FYI, in gnu/linux follow these simple steps to change your MAC address

ifconfig eth0 hw ether 00:19:DB:71:C8:30

if you get this error

SIOCSIFHWADDR: Device or resource busy - you may need to down the interface

do this

ifconfig eth0 down

and try to change the MAC again.

Here is a list of free wireless spots in Santa Fe. I’m sure I will miss some or make errors, please let me know.

* Santa Fe Baking Company (one of the first and best wireless spots in town, lots of seating and ample power, food and kitchen smell can be harsh)
* Pyramid Cafe (VERY fast internet, Amazing Mediterranean food)
* Second Street Brewery (very solid reliable connection, inside or out. great beer too!)
* Counter Culture Cafe (the qwest connection goes down a lot, the ap is too far from the seating area, but great place to hang, eat and work)
* Teahouse (The best selection of teas and generally good internet, very relaxing place. great food too)
* Aztec Cafe (small but friendly environment, good coffee and sandwiches)
* Blue Corn (the bar downtown has it, ask the bar tender for password (indiapaleale). The southside is open AP and I think the essid is jaguar)
* Flying Star Cafe (the wireless is always slow, food is overpriced and not very good. They use sputnik as a captive portal, its annoying to ask users to sign up for internet. I login with user: free pass: wireless)
* Santa Fe Brewing Company (its awesome they provide internet so far out of town)
* Backroad Pizza (south side location has it, not sure about the 2nd street location)
* Cafe Dominics (Fast net and decent food)

I wanted to share some notes on patching the Linux Libre kernel with realtime capabilities. The Linux-Libre project pulls out all the un-free bits from standard Linux. Contrary to popular belief, Linux has many non-free parts, small binary or obfuscated pieces of code for various hardware. I have a Lenovo T61 laptop. I removed the Intel wireless pci express card and put in a Atheros AR5008 wifi card using ath9k completely free wireless driver. Now my system (as far as I can tell:-) is completely free.

I make music and the realtime patch makes the latency of my system and soundcard very low. This is a unique advantage that the gnu/linux operating system gives its users. I highly recommend a realtime patch for anyone working with audio and video on gnu/linux.

Start by getting the rt patch http://www.kernel.org/pub/linux/kernel/projects/rt/ for the kernel version you want to compile.
Then get the corresponding Linux-Libre version http://www.linux-libre.fsfla.org/pub/linux-libre/releases/

tar xfvj linux-2.6.29.6-libre1.tar.bz2
cd linux-2.6.29.6
bzcat ../patch-2.6.29.6-rt23.bz2 | patch -p1

Now Linux is patched with realtime
now its time for

make menuconfig

from the RT How to:
* enable CONFIG_PREEMPT_RT
* activated the High-Resolution-Timer Option (Attention, the amount of supported platforms by the HR timer is still very limited. Right now the option is only supported on x86 systems, PowerPC and ARM Support are however in queue.)
* disabled all Power Management Options like ACPI or APM (not all ACPI functions are “bad”, but you will have to check very carefully to find out which function will affect your real time system. Thus it’s better to simply disable them all if you don’t need them. APM, however, is a no-go.) NOTE: Since rt patch 2.6.18-rt6 you will probably have to activate ACPI option to activate high resolution timer. Since the TSC timer on PC platforms, as used in the previous versions, are now marked as unsuitable for hrt mode due to many lacks of functionalities and reliabilties, you will need i.E. pm_timer as provided by ACPI to use as clock source. To activate the pm_timer, you can just activate the ACPI_SUPPORT in menuconfig and deactivate all other sub modules like “fan”, “processor” or “button”. If you have an old pc, which lacks ACPI support, you migh have problems using the high resolution timer.

I personally have not removed my power management options, as I use a laptop and want these features. I don’t notice any problems but have not tried it without them to know what I’m missing.

then compile the kernel, the debian way

fakeroot make-kpkg kernel_image

sudo dpkg -i linux-image-2.6.29.6-libre1-lapkah_2.6.29.6-libre1-lapkah-10.00.Custom_i386.deb

Here is my latest config and the debian package for libre realtime for lenovo t61

~ May your kernel build and your modules have your back ~

Moonlight is a Free implementation of Microsoft Silverlight. Its a Mono project, http://www.mono-project.com/Moonlight. I have read rumors that 2.0 will have support for Netflix. I went to install the 2.0 dev (currently 1.99.5). Logged into netflix and was denied. I was confused because moonlights dev website says that 1.99.5 is complete except for bug testing and a security audit. I did more reading and found that its not a limitation of moonlight at all, its the DRM (Digital Restrictions Management) that Netflix licenses from Microsoft called Play Ready. This is why we can’t watch Netflix with Moonlight. Another case where the end user suffers at the hands of DRM. The industry again is trying to control the user and hope no one cares. So what, if people save the movie streams from Netflix, you can copy as many dvd’s as you want when they show up in the mail! What happened to Fair Use? The move to hosted content is highly desireable by these industries. Now they can tell you what, how and when. Since its hosted on their servers, you can’t do a thing about it (other than not use it). Ugghh. I am disappointed…

A while ago Second Street Brewery asked for a good stable public wireless internet connection. Of course, the solution was obvious, openwrt on a linksys wrt54gl. The office, point of sale and public networks all share the same gateway. The problem was segregating the public wireless network from the private office lan. Sam (http://thepromisedlan.org) and I set out to setup a firewall to protect them. This is what we came up with:

check if the following is in /etc/config/firewall otherwise, add it

config include
option path /etc/firewall.user

and in /etc/firewall.user we put:

#Insert this into the chain, so 10.1.10.0/24 (office) can connect to public 192.168.10.0/24.
#This rule gets repeated by the setup script /etc/init.d/firewall.
iptables -I FORWARD 1 -m state --state RELATED,ESTABLISHED -j ACCEPT

#block all traffic from 192.168.10.0/24 (lan) to any possible private network address (10.*.*.*, 172.16-32.*.*, 192.168.*.*)
iptables -I FORWARD 2 -d 192.168.0.0/16 -j DROP
iptables -I FORWARD 2 -d 172.16.0.0/12 -j DROP
iptables -I FORWARD 2 -d 10.0.0.0/8 -j DROP

If you would like to have remote administration on the openwrt so you can access the luci web interface and ssh from the wan side of the router, you can change /etc/config/firewall wan zone to allow it. !!WARNING!! If you are directly connected to the internet, this will expose your open ports to the world. You should take precautions to secure them before changing this firewall rule.

config 'zone'
option 'name' 'wan'
option 'input' 'REJECT' #<- change this to ACCEPT
option 'output' 'ACCEPT'
option 'forward' 'REJECT'
option 'masq' '1'
