The Electronic Frontier Foundation (EFF) has come to the aid of Comcast customers after it was reported that the ISP was forging specific data packets, in a bid to discourage users from using Peer-to-Peer or P2P services like BitTorrent.
The EFF yesterday released software that'll help users detect these deliberate traffic tampering. Several ISPs world-wide use various techniques like blocking traffic over specific ports to discourage users from using the file sharing networks. "Protocol-specific discrimination gives ISPs a tremendous amount of power over the kinds of new applications and services that can be deployed by innovators and competitors. To the extent that practices like those employed by Comcast change the "end-to-end" architecture of the Internet, those practices jeopardize the Internet's vibrant innovation economy," explains the EFF press release.
EFF's "Test Your ISP" Project collects EFF's white papers, software tools, blog entries, and other materials relating to Comcast's discrimination. There's an in-depth whitepaper with technical details on the Comcast forgery "efforts". Also of interest is the hands-on whitepaper on detecting packet injections.
