Current Testbed Operational Status

The current testbed consists of 5 servers each with Ubuntu 9.04 linux operating system. Several of the nodes have a USRP1 attached. Within each USRP1 is a single RFX400 daughterboard that is able to transmit and receive from approximately 400 MHz - 500 MHz.

If another daughterboard is required for your project, please contact Dr. Timothy Newman (trnewman@…).

All CORNET nodes currently have private IP addresses, and are behind the CORNET firewall. However, the ssh port for each individual node is still directly accessible through the firewall. To access the CORNET nodes you must ssh to the CORNET gateway, 128.173.221.42, using a specific port that is unique to each CORNET node. The CORNET gateway redirects the ssh traffic to the appropriate CORNET node ssh server.

The port list is as follows:

• Node1-1: 6001 (USRP1-RFX400)
• Node1-2: 6002 (USRP1-RFX400)
• Node1-3: 6003 (USRP1-RFX400)
• Node1-4: 6004
• Node1-5: 6005

For example, to access node1-3, ssh to the IP address 128.173.221.42 using port 6003.

Accessing the network from Windows

From a windows machine, an SSH client is required in order to remotely access the CORNET nodes individually. A popular windows SSH client is  PuTTY.

Accessing the network from Linux

From a linux machine simply issue the following command

# ssh <username>@128.173.221.42 -p 600<node #>

For example, to login to CORNET node1-1 with the login name "testuser" do the following:

# ssh testuser@128.173.221.42 -p 6001

Obtaining Remote Access Login Information

To obtain a username for the CORNET nodes, please email Dr. Timothy Newman (trnewman@…).

Node Software

Each node contains the following software:

• Ubuntu Linux 9.04 Client Version
• GNU Radio 3.2.2
• OSSIE 0.74
