List the motes connected to your manager
- Switch on your manager and all your motes
- Wait for all motes to join.
On your manager, type the following commands:
> login user > sm
- You can type
sm(for “show motes”) multiple times, until all nodes are in the operational state, and no new motes are joining. List the MAC addresses of the motes attached to your manager in the following table:
Compare those MAC address to the label printed on your motes. What does the printed label represent?
Change your mote's Network Identifier
On your manager, type the follow command:
> login user > minfo
What is the network identifier of your manager (
netid)?- Ask your instructor for the netid of his/her manager
Type the following command on your mote:
mset netid <netid your instructor gave you>
- Power cycle your mote (switch it off and on)
- Make sure you see your mote appear on the instructor's manager.
- Revert your mote's netid to your manager's netid and power cycle your mote.
About Security
This trick of attaching to a different network works because there is no Access Control List (ACL) defined on the instructor's manager. In a production network, the ACL on the manager lists the motes that can join, and their join key. A different join key (or "password to connect") is used for each mote.
For maximum flexibility during this session, the instructors manager is configured so it accepts any mote.
