QUESTION:How do I change the default broadcast "All your 802.11b are belong to us." in Filename: Netstumbler.exe Version: 0.3.23 Filesize: 65.54 Kb ?

Answer:
1.Backup the executable first.

2.Using a hexeditor such as Ultraedit open the file in HEX mode and do an ASCII search for "All your 802.11b are belong to us." (without the quotes) and replace with something that fits such as "Resistance is futile. We are Borg."

3.Save new file and use.

QUESTION: How do I change my Windows MAC address?

1. back up your registry

2.Search for your driver in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro
l\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}

and search through the XXXX subkeys to find your NIC, then search for the value "NetworkAddress", if that value isn't present, which it may not be you may add in a string value and type in the value data "xxxxxxxxxxxx " with x being a MAC address for your vendor... if you put in a random mac that isn't bound to your vendor, you may end up with the card not binding.... after you are done editing the registry..

3. type IPCONFIG /ALL to see if it bound.

Q: If I run NetStumbler and my client manager at the same time, does one interfere with the other?

Yes. Most if not all Client Managers will conflict with NetStumbler's operation. It is best to disable the CM with running NetStumbler.

Asked by hkelley. Answered by Thorn

Q: Does scan speed have an effect on maintaining a connection in the background?

Yes, assuming you are connected to the same AP. While scanning, NS is sending some packets (i.e. the beacon request) to an AP. The faster this scan is performed, the more packets are being sent out in a given time. Due to the fact that the AP is receiving more packets, this is taking up some of the available bandwidth from that AP. Hence the connection is somewhat compromised.

QUESTION:Is it NMEA, NEMA, NEMO, ENMA?
ANSWER:NMEA

Quote:

The National Marine Electronics Association (NMEA) is the unifying force behind the entire marine electronics industry, bringing together all aspects of the industry for the betterment of all in our business.
http://www.nmea.org/

--------------------------------------------------------------------------------
NMEA 0183
--------------------------------------------------------------------------------

NMEA is a standard protocol, use by GPS receivers to transmit data. NMEA output is EIA-422A but for most purposes you can consider it RS-232 compatible. Use 4800 bps, 8 data bits, no parity and one stop bit (8N1). NMEA 0183 sentences are all ASCII. Each sentence begins with a dollarsign ($) and ends with a carriage return linefeed (). Data is comma delimited. All commas must be included as they act as markers. Some GPS do not send some of the fields. A checksum is optionally added (in a few cases it is manatory). Following the $ is the address field aaccc. aa is the device id. GP is used to identify GPS data. Transmission of the device ID is usually optional. ccc is the sentence formatter, otherwise known as the sentence name.
Here are the most important sentences ( for more infos read the text-file NMEA-FAQ ) :

Thorn · 06-03-2002

Q: I want to have a high powered AP (or Mobile.) What are the legal limits to adding a Radio Frequency amplifier?

A: The unlicensed use, legal limits for 802.11b are 30dB (1 Watt) effective radiated power for a Point-to-MultiPoint (PtMP) transmission, and 36dB (4 Watts) for a Point-to-Point (PtP). Effective radiated power is the output seen at the antenna.

To calculated the power output, take the final output from the devices, such as the AP or AP and amp, subtract any line losses from the coax and connectors, and add the gain of the antenna. To illustrate: Assuming for argument's sake a 1 Watt (30dB) amp, a 2dB line loss and a 5dB omni. (30 - 2) + 5 = 33 dB (2 Watts) output. Clearly illegal for anything but a PtP setup. To be legal with this antenna combination, you would need to have no more that a 27 dB (.5 Watt) amp. (27 - 2) + 5 = 30.

BTW, these power limits are for general public unlicensed use for 802.11b. Amatuer (ham) also use the 2.4Ghz area, and the hams have different power output limitations. However, hams can't use this for any business purposes.

Attached to the next message is a small text chart which shows the releationship of MilliWatts and Watts, to decibels.

SUBJECT: NetStumbler - General
Q: Does my (card brandname/chipset) work with NetStumbler?
A: Network Stumbler 0.3.23 works with cards using the HERMES chipset:
Lucent Technologies WaveLAN/IEEE (Agere ORiNOCO); Dell TrueMobile 1150 Series (PCMCIA and mini-PCI); Avaya Wireless PC Card; Toshiba Wireless LAN Card (PCMCIA and built-in); Compaq WL110; Cabletron/Enterasys Roamabout; Elsa Airlancer MC-11; ARtem ComCard 11Mbps; IBM High Rate Wireless LAN PC Card; 1stWave 1ST-PC-DSS11IS, DSS11IG, DSS11ES, DSS11EG; Sony Vaio PCG-R600 (Uses Orinoco MiniPCI)

Network Stumbler 0.3.23 DOES NOT work with cards using the Prism chipset:
3Com; Cisco; Compaq WL100; Dell TrueMobile 1100 Series; D-Link; IBM built-in cards; Intel; Intermec; Linksys; Symbol; SMC; Some Sony built-in cards??; Any 802.11a cards.

Just been stumbling on a nice new Sony Vaio PCG-R600 and i can confirm it works perfectly with Netstumbler under WinXP. I belive all the new Viao's use the same Orinoco MiniPCI card and should work with netstumbler.

Question Can I stop my PC from communicating with an AP that I have stumbled across?

Answer "Yup, turning off TCP/IP (and any other network protocols which might reach out) will stop the card from sending out those protocols. You don't have to delete the protocol. Just make sure it isn't enabled on the card while you're Stumbling. That way you can enable it later, when you need it. "Answer provided by Thorn. Thank you.
