• Chisel: A fast TCP/UDP tunnel over HTTP
  4 projects | news.ycombinator.com | 4 Apr 2024

  Using Proxytunnel [1] to do specifically this, in an environment where a packet inspecting proxy prevents SSH traffic.

  It supports connecting over HTTPs, so the traffic doesn't look fishy with the setup of: SSH Client -> HTTPs Encryption -> Corporate Packet Sniffing Proxy -> Your Server -> HTTPs Decryption -> SSHD Server

  Looking forward to explore chisel as well.

• Amazon's Older Kindles Will Start to Lose Their Internet Access in December

  It seems safe to post this too now that it's closing.

  It was also possible to SSH from the Kindle, over its 3G connection.

  So the SIM card could be kept in the Kindle, to be used as originally intended. But also (in an emergency) to use a few KB of data anywhere in the world for SSH.

  I was very careful to use <1 MB of data - as this use case isn't quite what the Kindle was designed for, probably. :-)

  From memory, broad steps were:

  - Root (jailbreak) the Kindle, and sideload "USB Networking" (to allow tethering - i.e., connect the Kindle to a computer via USB, and the computer would share the Kindle's Internet connection)

  - Read the magic key (which the HTTP proxy required) - it was sitting in a plaintext file within /var/local/ so could be easily read after rooting the Kindle

  - Run an SSH server on the HTTPS port (TCP/443), then use proxytunnel to connect via the HTTP proxy server - https://github.com/proxytunnel/proxytunnel (proxytunnel has an option to pass an arbitrary HTTP header containing the magic key)
