Is your ISP interfering with your BitTorrent connections? Cutting off your VOIP calls? Undermining the principles of network neutrality? In order to answer those questions, concerned Internet users need tools to test their Internet connections and gather evidence about ISP interference practices. After all, if it weren't for the testing efforts of Rob Topolski, the Associated Press, and EFF, Comcast would still be stone-walling about their now-infamous BitTorrent blocking efforts.
Developed by the Electronic Frontier Foundation, Switzerland is an open source software tool for testing the integrity of data communications over networks, ISPs and firewalls. It will spot IP packets which are forged or modified between clients, inform you, and give you copies of the modified packets.
Over the last several years, EFF has strongly opposed the use of closed, unverifiable voting technologies, bringing litigation to investigate faulty machines and challenge bad practices as well as backing legislation that would move us towards more trustworthy elections. For 2008, EFF is making a new contribution to help keep track of election issues, technology-related or otherwise.
In the 2008 Primary season, EFF successfully tested a beta version of Total Election Awareness (or "TEA"), a web-based application designed to help election monitoring efforts collect and analyze election-related incidents in real time.
Pcapdiff is a tool developed by the EFF to compare two packet captures and identify potentially forged, dropped, or mangled packets. Two technically-inclined friends can set up packet captures (e.g. tcpdump or Wireshark) on their own computers and produce network traffic between their two computers over the Internet. Later, they can run pcapdiff on the two packet capture files to identify suspicious packets for further investigation. See Detecting packet injection: a guide to observing packet spoofing by ISPs and EFF's Test Your ISP Project for more background.
