Are you suspecting that your evil ISP is manipulating BitTorrent streams? You can now confirm it by using the Switzerland Network Testing Tool. The funky piece of sofware was developed by Robb Topolski, who got famous for figuring out that Comcast was actually doing what was suspected above and actually told on them.
The Electronic Freedom Foundation has democratized Topolski’s achievement via the said tool. The application is a command line open source utility that tests data communications integrity not just in networks but also in ISPs and firewalls. The tool spots IP packets that have been modified or forged and gives users a copy of those modified packets.
This is going to be a really useful tool for those who think they are getting duped by their ISPs.
