war*ing

War dialing or wardialing is a method of automatically scanning telephone numbers using a modem, usually dialing every telephone number in a local area to find out where computers or fax machines are available, then attempting to access them by guessing passwords.

ToneLoc was a popular wardialing computer program for MS-DOS written in the early to mid-1990s by two programmers known by the pseudonyms Minor Threat and Mucho Maas. The name ToneLoc was short for “Tone Locator” and was a word play on the name of the rap artist known as Tone Lōc. The utility was created for the purpose of scanning for dial tones or modem carriers in order to find PBXes, long distance carriers, or other modems.

In the cracking scene of the 1980s, demon dialing was a technique by which a computer would repeatedly dial a number (usually to a crowded modem pool) in an attempt to gain access immediately after another user had hung up.

Wardriving is searching for Wi-Fi wireless networks by moving vehicle. It involves using a car or truck and a Wi-Fi-equipped computer, such as a laptop or a PDA, to detect the networks. It was also known (as of 2002) as “WiLDing” (Wireless Lan Driving, although this term never gained any popularity and is no longer used), originating in the San Francisco Bay Area with the Bay Area Wireless Users Group (BAWUG). It is similar to using a scanner for radio.

Many wardrivers use GPS devices to measure the location of the network find and log it on a website (the most popular is WiGLE). For better range, antennas are built or bought, and vary from omnidirectional to highly directional. Software for wardriving is freely available on the Internet, notably, NetStumbler for Windows, Kismet for Linux, and KisMac for Macintosh.

Wardriving was named after wardialing (popularized in the Matthew Broderick movie WarGames) because it also involves searching for computer systems with software that would use a phone modem to dial numbers sequentially and see which ones were connected to a fax machine or computer, or similar device. (Audio commentary on the Wargames DVD says that wardialing was named after the movie and the software did not openly exist before the movie.)

On the Road

On the Road: Nashville

Country music is sure big in Nashville.  It seeps into everything else.  Luckily, I grew up with country music and to some degree like a lot of it.  If you find yourself in Nashville though, the thing that stands out to me most is the might quantities of fried food that get consumed here.  Once again, lucky for me, I grew up with that too and love it.  Just can’t eat too much of it, which is hard to do here…

PS – Too many Tennessee Volunteer fans.  Don’t they have jobs or something?  Note to self: look into the unemployment rate here and see if an overabundance of fans correlates to massive job shortages.

Xsan: LUN

An Xserve RAID can be split into multiple logical units, referred to as a LUN.  Each side, or channel, of the RAID is, by default a single LUN. You can use the RAID Admin utility (located at /Applications/Server) to format each of these as multiple LUNs if you wish.  When the LUNs are formatting (which generally takes 48 hours) you will start to see them in disk utility.  Do not assign a file system to them yet if you are to use them with Xsan.  Instead you will use the cvlabel command to label each of your LUNs, which marks them as able to be used by Xsan.
