v11 v12 2 2 3 3 4 === '''NOTE:''' We are in the process of moving the preliminary testbed over to the actual 48 node testbed system. For this reason, you may encounter a varying degree of connection problems with the preliminary nodes. This is also the reason there are currently only 3 available, as the others have been migrated over. The full testbed will be available within the next 2 months. === 5 6 7 8 The current testbed consists of 3 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. 9 10 If another daughterboard is required for your project, please contact Dr. Timothy Newman (trnewman@vt.edu). 4 === '''NOTE:''' The preliminary testbed has not been completely SHUTDOWN. A limited portion of the regular testbed is now open. === 11 5 12 6 All CORNET nodes currently have private IP addresses, and are behind the CORNET firewall. However, the 13 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, ''128.173.221.4 2'', 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.7 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. 14 8 15 9 The port list is as follows: 16 10 17 * (OFFLINE) '''Node1-1''': 6001 (USRP1-RFX400) 18 * '''Node1-2''': 6002 (USRP1-RFX400) 19 * '''Node1-3''': 6003 (USRP1-RFX400) 11 * '''Node1-1''': 7001 12 * '''Node1-2''': 7002 13 * '''Node1-3''': 7003 14 * '''Node1-4''': 7004 15 * '''Node1-5''': 7005 16 * '''Node1-6''': 7006 17 * '''Node1-7''': 7007 18 * '''Node1-8''': 7008 19 * '''Node1-9''': 7009 20 * '''Node1-10''': 7010 21 * '''Node1-11''': 7011 22 * '''Node1-12''': 7012 23 * '''Node2-1''': 7013 24 * '''Node2-2''': 7014 25 * '''Node2-3''': 7015 26 * '''Node2-4''': 7016 27 * '''Node2-5''': 7017 28 * '''Node2-6''': 7018 29 * '''Node2-7''': 7019 30 * '''Node2-8''': 7020 31 * '''Node2-9''': 7021 32 * '''Node2-10''': 7022 33 * '''Node2-11''': 7023 34 * '''Node2-12''': 7024 35 * '''Node3-1''': 7025 36 * '''Node3-2''': 7026 37 * '''Node3-3''': 7027 38 * '''Node3-4''': 7028 39 * '''Node3-5''': 7029 40 * '''Node3-6''': 7030 41 * '''Node3-7''': 7031 42 * '''Node3-8''': 7032 43 * '''Node3-9''': 7033 44 * '''Node3-10''': 7034 45 * '''Node3-11''': 7035 46 * '''Node3-12''': 7036 47 * '''Node4-1''': 7037 48 * '''Node4-2''': 7038 49 * '''Node4-3''': 7039 50 * '''Node4-4''': 7040 51 * '''Node4-5''': 7041 52 * '''Node4-6''': 7042 53 * '''Node4-7''': 7043 54 * '''Node4-8''': 7044 55 * '''Node4-9''': 7045 56 * '''Node4-10''': 7046 57 * '''Node4-11''': 7047 58 * '''Node4-12''': 7048 20 59 21 For example, to access node1-3, ssh to the IP address ''128.173.221.4 2'' using port 6003.60 For example, to access node1-3, ssh to the IP address ''128.173.221.40'' using port 7003. 22 61 23 62 === Accessing the network from Windows === … … 25 64 26 65 === Accessing the network from Linux === 27 From a linux machine simply issue the following command where the port is 6000 + the node # you want to log into.66 From a linux machine simply issue the following command where the port is 7000 + the node # you want to log into. 28 67 29 68 {{{ 30 # ssh <username>@128.173.221.42 -p <6000 + node#>69 # ssh -X <username>@128.173.221.40 -p <7000 + node#> 31 70 }}} 71 72 Note: the -X allows X11 forwarding for running X11 applications remotely. 32 73 33 74 For example, to login to CORNET node1-2 with the login name "testuser" do the following: 34 75 35 76 {{{ 36 # ssh testuser@128.173.221.42 -p 600277 # ssh -X testuser@128.173.221.40 -p 7002 37 78 }}} 38 79 … … 40 81 41 82 {{{ 42 # ssh testuser@128.173.221.4 2 -p 600383 # ssh testuser@128.173.221.40 -p 7003 43 84 }}} 44 85 … … 50 91 51 92 * Ubuntu Linux 9.04 Client Version 52 * GNU Radio 3. 2.293 * GNU Radio 3.3.0 53 94 54 95
