## HOWTO: Start `ssh`/login to your Chumby

i.e. how to get a "shell".

  1. Start the Control Panel by hitting the button on the top of your Chumby.
  1. Select "Settings".
  1. Select "Chumby Info".
  1. Select the hidden π (pi) symbol in the top right of the screen.
  1. Note the IP address of the Chumby.
  1. Select "SSHD".
  1. From another computer, `ssh` into your Chumby as root:

        $ ssh -l root 192.168.2.4

info](http://wiki.chumby.com/mediawiki/index.php/Chumby_tricks#Open_a_secure_shell_console_on_the_chumby)

To start `ssh` at boot, `ssh` in to your Chumby as above, then

    $ touch /psp/start_sshd
  
(Remove this file to disable this behaviour.)

You can also initiate `sshd` by connecting a USB flash drive with an empty
file called `start_sshd` in the root directory ([more
info](http://wiki.chumby.com/mediawiki/index.php/Chumby_tricks#Launching_sshd_at_startup)).

(A USB drive will appear at `/mnt/usb`.)

## FAQ: What's the "fbcgi" option in the "hidden" preferences?

This apparently [enables access to the fram buffer (`/dev/fb` content) via
CGI](http://wiki.chumby.com/mediawiki/index.php/Chumby_tricks#Hidden_screen_in_Control_Panel).

(See above for how to enable the hidden preferences.)

## HOWTO: Run CGI scripts on the Chumby's webserver

The Chumby starts a small webserver at startup which can be accessed at its
IP address.  (See Control Panel | Settings | Chumby Info for the IP address.)

CGI scripts that have been placed in `/psp/cgi-bin` are accessible at
`http://a.b.c.d/cgi-bin/custom/foo.cgi`.  For example,

    $ cat /psp/cgi-bin/hello.cgi
    #!/bin/sh
    
    echo "Content-Type: text/plain"
    echo
    echo "Hello, World!"

    $ ifconfig rausb0 | fgrep inet
    inet addr:192.168.2.4  Bcast:192.168.2.255  Mask:255.255.255.0

Then, from your computer, go to <http://192.168.2.4/cgi-bin/custom/hello.cgi>.

## HOWTO: Run arbitrary Flash files on your Chumby

`ssh` in to your Chumby (for more information, see elsewhere in this
document) and then either `wget` the SWF, `scp` it from another computer, or
copy it onto a USB flash drive.  Then, run it with:

    $ chumbyflashplayer.x -z -i foo.swf

## FAQ: How can I use my chumby as a BitTorrent client?

`ssh` in, as above, then:

    $ trap '' 1
    $ chumbytorrent mytorrent.torrent
