Board FRAM - Board Farm Remote Access Management

FEATURES

• FRAM provides access to a single board from a remote location:

  • Board control
    • Power
  • Reset
  • Optional accessory switch
  • Optional wake-up key and/or Wake-on-LAN
  • Board monitoring
  • Serial console
    • Power consumption
  • Board management
  • Kernel and DTB upload
  • Automatic board user environment setup
  • Multi-User access locking
  • Restricted administration mode

• FRAM needs no special tools on the client, just ssh (cfr. gitolite)

  ssh <board>@<remote> <command> ...

• FRAM provides a convenience wrapper, to simplify access to remote boards in multiple farms:

  fram <nickname> <command> ...

• FRAM can be made to work with any backend that you use to control your board farm.

• FRAM has a builtin help command.

DESIGN DECISIONS

• Each development board has its own UNIX user (cfr. Android apps).

• Authentication is provided by SSH

  ~/.ssh/authorized_keys should contain only lines of the form:

  restrict,pty,command="/path/to/fram-server $user" ssh-rsa $key $keyid

• Separation between remote access and board farm infrastructure: Actual board control operations are performed by shell functions, scripts, and/or external tools, to be provided by you.

• KISS, easy to review for correctness and security.

• Simple configuration file
