== Current Testbed Operational Status ==


=== '''NOTE:'''  The preliminary testbed has not been completely SHUTDOWN.  A limited portion of the regular testbed is now open. ===

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, ''128.173.221.40'', 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.

For information on the physical locations of the RF portion of the node, see here: [wiki:CORNET/NetworkTopography CORNET Node Location and Status Information][[BR]]

The port list is as follows:

 * '''Node1-1''': 7001 
 * '''Node1-2''': 7002 
 * '''Node1-3''': 7003

 * '''Node1-10''': 7010 
 * '''Node1-11''': 7011 
 * '''Node1-12''': 7012
 * '''Node2-1''': 7013 
 * '''Node2-2''': 7014

For example, to access node1-3, ssh to the IP address ''128.173.221.40'' using port 7003. 

=== 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 [http://www.chiark.greenend.org.uk/~sgtatham/putty/ PuTTY].

=== Accessing the network from Linux ===
From a linux machine simply issue the following command where the port is 7000 + the node # you want to log into.

{{{
# ssh -X <username>@128.173.221.40 -p <7000 + node#>
}}}

Note: the -X allows X11 forwarding for running X11 applications remotely.  

For example, to login to CORNET node1-2 with the login name "testuser" do the following:

{{{
# ssh -X testuser@128.173.221.40 -p 7002
}}}

To login to CORNET node1-3 with the login name "testuser" do the following:

{{{
# ssh testuser@128.173.221.40 -p 7003
}}}
 
=== Obtaining Remote Access Login Information ===
To obtain a username for the CORNET nodes, please email Dr. Timothy Newman (trnewman@vt.edu).

=== Node Software ===
Each node contains the following software:

 * Ubuntu Linux 9.04 Client Version
 * GNU Radio 3.3.0
