I imagine there is a setting in the config file, but I don't know how to get into it since my favorite editor is not installed(nano).

To diagnose you'll need to SSH into the roborio (user: admin, password: just hit enter).

• Does /dev/video0 exist? If not, then your camera isn't recognized by the roboRIO and mjpg-streamer won't be running. You can use 'dmesg' to look at the kernel messages and try to divine what happened. Not all cameras will be supported -- but I'm not 100% sure what ones are supported, or how to get the list (probably some linux magic)
• Is mjpg-streamer running or did it die? "ps -Af | grep mjpg" will show you
• If it's running, is it listening on the right port? "netstat -ln" can show you what ports are being listened on, 5800 should be in the list.
• If /dev/video0 exists and mjpg-streamer dies, then there's something else wrong and you'll need to run mjpg-streamer on the command line. Unfortunately, I haven't put anything in the package to do this using the settings, so it's a bit verbose...
