Yes indeed. Us greybeards were tunneling ssh through DNS using a Perl-based hacking tool thrown together by Dan Kaminsky in 2004 called “OzymanDNS”. DNS tunneling is now ubiquitously used for data exfiltration and consequently all major DNS platforms have methods to detect it.
Mind you, this was before the age of WiFi on airplanes. But within other gated networks, it used to work quite well. I recall getting tens of Kbps.
- rft 2y agoSo that was the name of it! I only had vague recollections of me setting up PuTTY with a proxycommand involving some kind of compiled to .exe Perl script. Worked out in the end with a free VPS and train station wifi. As usual, I spent far longer setting this up than actually using it, but it was one of the many small things that got me started on my career path. Thank you for the trip down memory lane!
