HTTP Web Terminal for WARP VM

[mrzzy]

Motivation

One of the original aims of WARP VM is provide access to a development environment from a sandboxed & firewall-ed organization laptop for accessing the internet. Despite implementing HTTPS access in #20, access to WARP VM from the organization laptop is still blocked by a TCP reset.

While the exact reason of the TCP reset cannot be determined with having access to the organisation's firewall, we could experiment in accessing via plaintext HTTP, based on the hypothesis that traffic would have a lower likelihood to be blocked if it can be inspected by the firewall.

Proposal

Add HTTP Web Terminal for WARP VM:

• create systemd service ttyd-http to serve a plaintext HTTP terminal.
  • run TTYD to listen for requests on port 7682 on boot.
  • add iptables rules to redirect HTTP (port 80) traffic to TTYD (port 7682).
