Re: Yikes!

Okay! The root disk image is fux0r3d it has a kernel, but nothing else, and it kernel panics on boot. So, we'll need to re-image it. I suggest we also make a duplicate backup machine running the same image.

Is there an image? Hopefully?

Hi all,

so yeah it looks like the central linux box is not booting up. We've had such a problem before but i went there, literally just rebooted and it sprang to life again so I have no idea what happened there.

Brian, there should be a keyboard and a screen already in the cube sitting on the central platform.

Try plugging those in and seeing if you can boot up the box. 

If it turns out the box has truly died (which i doubt, frankly) we'll need to order or find another box.

Lee gave me a black MacBook that is sitting on my dresser in my room that we could use although it will take a little software fiddling to get it to work since the /usb/ttyUSB devices are called something else.

I think just making symlinks to /usb/ttyUDBx where x = 1..13 will work. I can do all that remotely though, i just need a running box. The IP needs to be set statically to 10.0.40.85 if i remember correctly.

As for power to the LEDs i believe that is all in goo shape.  However if it does turns out there are dead powersupplies then the temporary fix is easy:

Currently each dimduino is only connected to a single computer powersupply (ATX style). THe reason is that the other, aluminum cased water-proof supplies were giving a dirty signal and were causing USB disconnections. However they do work in principle so if you neded to replace one of the ATXes just plug in a nearby aluminum supply - they are all still in there, just disconnected.

I'll try and check my mail as frequently as I can to help with any issues. Once the central machine comes back online i can prolly do most of the software work from here.

Thanks!

Oh, and the main computer is sitting at AND, I have a date, but if someone is feeling really ambitious and wants to come over and magically fix it all, I won't complain. But, I at least need to know how to make a new cube image.

Where's the source repo again?

Thanks for the diagnosis!

Chris set up the machine originally - sadly don't think there's an image
or a duplicated box.

I think we need is a clean Ubuntu install and then we can just
re-checkout the code. I can deal with the scripting part etc once it's
back at PacSci and accessible from the intrewebs.
So I guess the course of action is:
a) reinstall Ubuntu
b) set it to static IP 10.0.40.85
c) install a user "cube" and make him be sudoable. Password was
"PowerOfLove" for both accounts
d) in user cube's home dir do
hg clone https://mike...@code.google.com/p/grooviks-cube/

Follow instructions in grooviks-cube/webserver/README to test-
run the server

YOu may hae to install some missing packages here (e.g. hg and probably
django and whatnot, more info in the README )

e) make a script in /etc/rc.2/ to autostart

./manage.py runserver 0.0.0.0:8080"
hookbox -d -r bakonv8 -p 2974 --cbhost=127.0.0.1 --cbport=8080"
./groovikhookbox.py"

in their respective directories (see README)

z) make an image so next time we dont have to do all this again. Sorry
for dropping the ball on this - that was dumb of me.
(actually wait b4 making the image until we know everything is back to
working order)

Thanks for you guys' help!

Okay the cubes fixed. two notable errata  it runs on port 80 not port 8080 and the netmask seems to be whack 16 not whack 24

Thank you Brian - you're our hero!!

YOu mean its reinstalled and installed physically back at PacSci ?
I still can't log into it remotely .. maybe there's a firewall issue ?
I'll email Michael (the sysadmin at pacsci) to see if he changed something.
