Schoolserver Testing

These are the tests performed to validate proper operation of the XS Schoolserver software.

Connectivity

The schoolserver provides basic network connectivity to laptops connected to a school mesh.

Basic Mesh Connectivity

This test verifies that laptops on a school mesh are provided with basic connectivity to the schoolserver, over the wireless mesh network.

These actions should be repeated on each of the three mesh channel.

Setup:

1. Setup a school server with three active antennas.

Actions:

1. Using an XO laptop, associate with one mesh channel. The mesh channel used by a laptop can be selected by clicking on a mesh channel in the neighborhood view.

Verify:

1. Switch to a text terminal
2. Verify that an IP address has been assigned by typing ifconfig eth0. The address assigned should be in the range 172.18.16.0 to 172.18.63.255.
3. Verify that the laptop can communicate with the school server using ping:

ping 172.18.0.1

Domain Name System

This test verifies that laptops on a school mesh can properly resolve DNS names.

Setup:

1. Setup a school server with one to three active antennas. The school server should be connected to the Internet through its WAN connection.

Actions:

1. Associate a laptop with a mesh channel.

Verify:

1. Switch to a text terminal
2. Verify that DNS has been configured properly by checking /etc/resolv.conf to see that a DNS server has been assigned. It should look like (the actual domain listed after search may be different):

; generated by /sbin/dhclient-script
search random.xs.laptop.org
nameserver 172.16.0.1

1. Check that DNS on the schoolserver is operating properly using ping (additional service names defined in School Service Names should also be tested):

ping schoolserver
ping school
ping www
ping time
ping presence

1. Finally, check that DNS properly resolves non-local names:

ping wiki.laptop.org
