OnionCat can provide access to using UDP and IPv6 over Tor without the extra openssh openvpn layers. Onion to onion sets an average range of RTT due to hopcount and speed of light. Software layers add on top of that. Those widely deploying onioncat / onionvpn should be aware of some caveats and good future oppurtunities... - Users have to compile and run them, they may not be as available platform wide as openvpn / ssh. That's minor since joint effort with those projects can be started to port, document, and publish them [and their binaries again], etc. - They're IPv6 only, that's minor, expected and ok since everyone has local IPv6 stacks and apps now and IPv6 is the way forward. [The encapsulated IPv4 mode is a hack, use IPv6 instead.] - Doesn't yet work with v3 onion services automagically. Tor may require an address resolution / translation layer to do that, which would probably also end up handling hostnames naming layer as a bonus. This is a big oppurtunity for anyone who wants to design it :) - Tor is thinking to kill off v2 onion services despite all the uses and users of IPv6 and UDP via onioncat / onionvpn. There is a trac ticket somewhere to continue v2 onion services in perpetuity, with various levels of support, up to and including fork of tor client and or network. Continuation is a fine middle ground. A few of the related tickets... https://trac.torproject.org/projects/tor/ticket/23079 https://trac.torproject.org/projects/tor/ticket/6001 https://trac.torproject.org/projects/tor/ticket/25955 There are some communities using bittorrent, voice comms, and other applications for many years, entirely within onionland, via onioncat, onionvpn, udp, ipv6. So the tech works pretty good :) See also... https://www.onioncat.org/ https://github.com/rahra/onioncat https://github.com/david415/onionvpn https://www.youtube.com/watch?v=Zj4hSx6cW80 https://itsecx.fhstp.ac.at/wp-content/uploads/2014/11/FischerOnionCat.pdf search: the lists for "onioncat", there are detailed posts that could be collated for reference by those working on things. -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
