iodine, icmptx, ozymandns,…
After a first round of looking around what exists (ICMPTX, NSTX, ozymandns, tcp-over-dns, iodine or openvpn) I figured out that iodine seemed to have the best cards to get working. It seems that over the last 2-3 years commercial providers have become aware of DNS-loopholes and are now using more and more deep-packet inspection and similar techniques to obstruct you. Despite the rise of affordable wireless broadband there are still a lot of commercial wifi-spots around. But finding them, figuring out how they work and doing real-life tests with your tunnel schemes isn’t easy.
Openvpn
Tried it over port 53, it works, but I couldn’t find a hotspot that didn’t cut that off: ergo not useable for me.
Iodine
Installed it first from debian repositories, I’m still struggling to debug it. There is no firewall and still somewhow my crafted packets don´t get in my tcpdump filters. I need to sit down and rethink this over on a quuiet moment.
Ozymandns
His page was unavailable when I checked it. Project dead?
