Alright, let’s get this out of the way right now—Hacking the Cable Modemis not a Hacksbook. If you pick this book up thinking you want to squeeze a littleextra out of the cable modem the Comcast guy just installed, put thebook down and walk away. Hacking the Cable Modem is aimed at people whoare willing to get into the guts of their cable modem and override therestrictions put in place by the cable companies. The sample chaptershould give you a decent idea of the book’s target audience; it’sentitled “Building a Console Cable.”

If you’re still here after my clarification and still interested intaking a whack at your cable modem, then you’re in the right place.Before going too deep into what the book offers, though, I want tomention two caveats. First, I did not attempt any of these hacks. Ididn’t expect the book to be as in-depth as it turned out to be, and Iwasn’t comfortable with the concept of modifying my leased cable modem.Second, most of the techniques discussed in the book are examined from aWindows-centric viewpoint. With some research, you could probablyreplicate some of the techniques on OS X, but others might requiretemporarily switching over to Windows.

The book’s 23 chapters basically fit into three different sections:background, basics of hacking, and hacking specific modems. Thebackground section covers the evolution of the cable modem. This startswith the earliest days of cable Internet access, when pretty much everytype of cable modem used a different technique for connecting the userto the Internet. As a result, users pretty much needed to use anISP-provided cable to ensure a reliable connection to the Internet. Thehistory continues through the development and evolution of the DOCSISstandard, which established the protocols for ISP and cable modemproducers and opened up a variety of modem options for end-users.

The background section also covers the history of cable modem hacking.This includes the birth of these practices and the author’s extensiveexperience with hacking cable modems. Personally, I found most of thismaterial a bit dry, though I can understand why some people would wantto have this information, particularly those people interested inmodifying the guts of their cable modems.

Jumping ahead, the book ends with four chapters on hacking specificcable modems. Consider this the “cheat-sheet” section of the book. Ifyou desired, you could use the book as a buying guide for your nextcable modem purchase. You probably don’t want to perform these hacks ona leased cable modem, so you may as well buy a modem for which you’vegot instructions.

One of the dangers of referencing particular products is that thematerial can rapidly become dated as companies update their productlines. Hacking the Cable Modem’s middle section, related to the basicsof hacking, helps to alleviate this concern. Over the course of 13chapters, DerEngel delves into information and techniques necessary tounderstand cable modem hacking. Most of the information is presentedwithin the context of hacking a Motorola SURFboard, but DerEngelprovides enough information that a motivated hacker can adapt theinformation to another cable modem. The only concern I have aboutobsolescence is whether changes to the DOCSIS standards may invalidatesome of the information in the book.

Although Hacking the Cable Modem was not the book I hoped, I still foundit to be an interesting reference. If you own a cable modem and areinterested in breaking out the soldering iron, I definitely recommendchecking out the book. It’s a little dense at times and you definitelyneed to understand what you are doing, but the book definitely feelslike a comprehensive reference on getting the most out of your cablemodem.

Steps:

Cable Modem Mac Address Hack Free

1. Get cable modem's MAC address - You can either look at the back of the modem to get this MAC Address or you can logon to your cable modem with your browser, http://192.168.100.1/ . This is internal HTML pages stored within your DOCsis cable modem (SB5100, SB4100 and SB3100) that gives you even more vital information on configuration unless it is turned off by your ISP. This feature might be totally turned off by your ISP.
2. Get your ISP's TFTP server IP address.
3. Get name and path of the configuration file or Image file stored in the ISP's TFTP server - For getting this vital information you have to do an SNMP walk over your modem. For doing this you can use any one of the tools below. There's a program called QUERY.EXE from Weird Solutions which is a BOOTP packet request program that will tell you everything you need to know, without all these extra steps. It will display the Image Filename, TFTP server address, which is really all you need to get started. To use this BOOTP QUERY tool, you need the MAC address of your cable modemYou can download this from http://www.weird-solutions.com/_bin/bootpq.exe or Solarwinds SNMP program, http://www3.solarwinds.net/downloads/SolarWinds-EE-V7-Eval.exe or DOCSIS Diagnosis Utility, http://homepage.ntlworld.com/robin.d.h.walker/docsdiag/docsdiag.zipor SNMPWALK Tool from http://www.bradford-sw.com/board/board.cgi?id=BSI_Tools&action=download&gul=13
