2017 Contest Environment Information

Creating a bootable USB using the diskutil command on MacOS

  1. Download the USB image (compressed with gzip) (Checksums)
  2. Unzip the image.
  3. With USB drive not inserted, run diskutil list.
  4. Insert USB drive, and again run diskutil list to see the new drive / your USB drive. The drive will be referred to by /dev/diskN (where N is a number).
  5. Run diskutil unmountDisk /dev/diskN.
  6. Run sudo dd if=path/to/gny-2017.img of=/dev/rdiskN bs=1m. This operation takes about 10 minutes. You can press control-T in the console to send the INFO signal and see the progress about this operation.
  7. When finished, run diskutil eject /dev/diskN

Boot into the envrionment

Reboot your Mac computer, and when the start-up chime sounds, press Option. Select EFI Boot, and launch the contest image. The system should automatically login as user "contestant", but this does not always happen. If it doesn't, just hit ENTER twice when you see the login screen.

At this point, you should try bringing up the Firefox browser. It should take you to the home page http://contest-server:8017/, where you will find the usual contest webpage, including instructions for configuring a printer, if you need one. There is also a menu item (on the left) for making submissions during the contest. Ignore this for now.
