Connecting from a MacOS host

SSH (with shared internet)

  • Connect the OreSat Linux card to host using a USB cable

  • Go to System Settings => Network and wait for the BeagleBone connection to come up

  • Go to System Settings => General => Sharing, click on the i next to Internet Sharing, check the checkbox next to BeagleBone, and then check the checkbox for Internet Sharing

  • Open a terminal and watch ifconfig

    $ watch -n 1 ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
  ...
en0: flags=8822<BROADCAST,SMART,SIMPLEX,MULTICAST> mtu 1500
  ...
en7: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1486
  ether 60:64:05:f9:0d:06

  status: active
bridge100: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1486

  • Once the bridge show up note the IP address and stop the watch (control-C). In the example ifconfig above, the address for the bridge would be 192.168.2.1.

  • Go back to System Settings => Network and edit BeagleBone and change it to Using DHCP with manual address and set the address to the address found from ifconfig.

  • SSH onto the card. Password is temppwd. Replace oresat-dev in the following command with the image hostname as needed.

    $ ssh debian@oresat-dev.local

  • Make sure shared internet is working

    $ ping www.google.com
