mediactl

autostart on RPI

See this for a description of how to start chromium via .xinit

note about apt and git

In /etc/apt/apt.conf.d/proxy.conf there is a proxy connection setup:

# "socks5h" means proxy with DNS resolving ability
Acquire {
  HTTP::proxy "socks5h://127.0.0.1:8080";
  HTTPS::proxy "socks5h://127.0.0.1:8080";
}

So we can then ssh into the machine with a tunnel

ssh -R 127.0.0.1:8080 mediactl
