Questions

  • Is the XO connected to Link-local or a mesh?
  • Is it connected to an MPP?
  • Is it connected to the internet?
  • Is it connected to a jabber server?
  • What is the ip?

Layer 2

The wireless configuration of the network can be examined using the iwconfig eth0 command. We get MAC layer information such as

  1. ESSID
    • olpc-mesh : Indicates a mesh with or without internet connectivity
  2. Mode
    • Managed : It is an Access Point(AP) configuration
    • Ad-hoc : It is a mesh configuration(no infrastracture)
  3. Frequency
    • 2.412 : Channel 1
    • 2.437 : Channel 6
    • 2.462 : Channel 11
    • Channels 1,6, 11 can be used to join a Link-local mesh
    • Channels 1, 6, 11 can also be a Schoolserver mesh (ch 1 is almost always on at OLPC offices)
    • At OLPC offices, '802.11 Media lab' AP operates on Channels 6 and 11
  4. Cell/AP Mac
    • Access Point : The AP's MAC
    • Cell : A virtual 02:xx:xx:... MAC address assigned by the some mesh points. It indicates mesh configuration
