| The controller viveks-unsup.cs is housed in the WiNGS lab, room #3360 All access to the nodes go through the controller. To gain acces to the nodes the user should ssh to the controllder, and then ssh to the nodes. The controller should not be shutdown for any reason. However, if it has to rebooted, please follow these instructions given below to bring the testbed online. | The controller viveks-unsup.cs is housed in the WiNGS lab, room #3360 All access to the nodes go through the controller.

| Most of the nodes are Soekris, model 4826 . They are placed on the office rooms in the 3rd, 4th, 5th, 6th and 7th floors of the building. Both the main tower, and the condor tower house these nodes. Placing of nodes and configuring is a tedious process that has to go through CSL. See below for contact information. We use Power Over Ethernet (POE) to for power control of these nodes. They are connected to 5 POE switches | Most of the nodes are Soekris, model 4826 .

| - | Port Mapping | + | ==== Port Mapping ==== |
| Mapping of nodes to particular ports can be found in /usr/sbin/poe_control Please do not change this mapping unless the nodes are specifically moved from one location to another. Then still you should consult Vivek or Shravanme before you change anything. | Mapping of nodes to particular ports can be found in /usr/sbin/poe_control Please do not change this mapping unless the nodes are specifically moved from one location to another.

| Any user should try to use the existing setup, and try to work with that, unless, creating a new image is necessary. By default, the node should use the os named expt_client (see inside /tftpboot/). We dont have space to allow everyone to create their own images for experimentation. As I said earlier you can decide which node boots to which OS by changing entries in /etc/bootptab. | Any user should try to use the existing setup, and try to work with that, unless, creating a new image is necessary.
