Since we have been discussing ways for people with limited Internet access to make use of Tor, I decided to run a service on one of my hosts that provides a free gateway to Tor via OzymanDNS. I posted a web page about it here: http://afs.eecs.harvard.edu/~goodell/blossom/tor-via-dns.html Please check it out and send me comments. Here is the overview: Thanks to a nifty tool from Dan Kaminsky called OzymanDNS, we have successfully constructed a gateway to the Tor network that allows an arbitrary host to establish a secure connection to the Tor network even if its upstream ISP filters all traffic except DNS requests. We provide access to this gateway as a free service. This means that if you and your laptop find yourselves in an environment that forbids you from communicating with the Internet except to send and receive DNS data, then you can still access network resources visible via the Tor network. Performance is limited to a maximum of about 1.7 kB/s, which is comparable to the speed of a 14.4 kbps modem. Thanks, Geoff [bcc]
