Chumby tricks

Finding your Chumby

Browsing bonjour services from the command line

I downloaded the Bonjour Browser (under OSX) and run it.

You can see the Chumby listed here in the Bonjour Browser, along with the IP Address.

HTTPD/Built in Web Server

The Chumby advertises itself via Bonjour, Apple's system for advertising services.

You can use the Bonjour bookmark that supposedly exists in Safari, but I am unable to find that. So used the tools under Finding Your Chumby to get an IP address to use.

Use the IP address you got from above, for example: http://10.0.1.11

There are limited options on the web server right now, but you get a pretty picture and you can see wireless stats.

SSH

The Chumby comes with sshd, but it is not running by default (can you imagine chumby's running all over, usually behind NAT, but sometimes exposed, with sshd enabled and a default password? It would be chaos I say as people rooted my alarm clock! Enough fear mongering!)

You need to run sshd. This should work-names and paths _might_ be slightly off, so please fix this if you get better information.

1. Pull out the USB wireless dongle

2. connect a USB hub

3. connect your USB Wireless to one port of the hub

4. Create a file called chumbydebug on a USB thumb drive (you can't format the drive with the Mac HFS (?) file system.)

The file should contain this line: /bin/sshd

5. Connect the USB drive

6. Power up the Chumby

7. ssh to the IP address found in the bonjour browser (see above under HTTPD) File:Example.jpg

I don't know the default username, or default password...

8. To See if sshd is running, from a terminal window: dns-sd -B _ssh._tcp

These instructions are untested. Please update them as appropriate.

Not Working Yet

I tried this, using the SSH port on the back of chumby, and it did not work (ssh connections refused). I tried filenames chumbydebug, debugchumby, chumby_debug, and debug_chumby; file contents "/bin/sshd", "/sbin/sshd", and "sshd"; and file formats FAT and FAT-32. I did *not* use the USB port connected to the chumby itself (as the steps above suggested), but my USB drive light did come on, so I'm assuming that the USB port in the back is functional.

Chumby via Serial

There is a serial port somewhere. Getting to it involves a special cable and 'shims' and getting voltages right-if you attach a straight serial cable you will, apparantly, blow it up.

I believe you need a RS-32 to TTL voltage converter to use the serial port. Google it.

There is also a USB port
