    EtherBoot is an all-in-one application for interfacing a cable modem to your computer via use of a console cable. This software will automatically halt the startup process of SB3100, SB4100, and SB4200 series cable modems, and then allow you to boot a firmware file from your computer into the cable modem's memory.

Using this software is ideal for changing firmware (such as installing SIGMA) or revising a dead cable from a bad firmware update. This is the software that is included with the RS-232 v2 board.

Current version: 1.5

Availability: Members Only

    FIP is an application that decompresses and compresses firmware for the SB4xxx series cable modem. This application is useful when disassembling firmware, or when it is necessary to decompress a firmware image, patch it with a firmware mod and then compress it again. Because this application is very important, there is also a Linux version available.

Current version: 1.6

Availability: Public

File size: 121,496 bytes.

OneStep: ZUP

OneStep is the software that took cable modem hacking mainstream. This famous application accomplishes the task of uncapping by incorporating all of the tedious steps into one easy to use program. By making uncapping easier, OneStep introduced cable modem hacking to individuals who may not have been able to accomplish it otherwise (and created many security concerns for service providers in the process). This application does require the Java runtime environment.

Current version: 1.5

Availability: Public

File size: 346,543 bytes.

DiFile Thief

DiFile Thief is a packet sniffer that captures DHCP packets with boot filenames (also known as a config file). The purpose of this application is to discover all of the config files used on your local service provider. This application does require the WinPcap driver installed (www.winpcap.org).

Current version: BETA 2

Availability: Public

File size: 19,361 bytes.

DiFileCPE is an all purpose config file editor and viewer. Using this application, you can drag-and-drop a config file into the main window and it will automatically display the contents of the config file for you to view. This application is most useful when you want to know the download and upload speeds of a config file, or the SNMP community string.

TFTPD is a multi-threaded (allows multiple simultaneous transfers) TFTP server. This software is required when transferring files (such as firmware or configs) from your computer to your cable modem.

Current version: 116

Availability: Public

File size: 14,223 bytes.

Boot Server

The purpose of this software is to host a firmware image for a cable modem to boot from. Generally, you will need to decompress a firmware image using FIP, add a ELF header (using the ELF utility below) and then rename the file to vxWorks.st. This application requires the VB6 runtime library.

Current version: 1.02

Availability: Public

File size: 19,553 bytes.
