| | 6 | All CORNET nodes currently have private IP addresses, and are behind the CORNET firewall. However, the |
| | 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. |

| | 62 | For example, to access node1-3, ssh to the IP address ''128.173.221.40'' using port 7003. |
| | 63 | |
| | 64 | === Accessing the network from Windows === |
| | 65 | 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]. |
| | 66 | |
| | 67 | === Accessing the network from Linux === |
| | 68 | From a linux machine simply issue the following command where the port is 7000 + the node # you want to log into. |
| | 69 | |
| | 70 | {{{ |
| | 71 | # ssh -X <username>@128.173.221.40 -p <7000 + node#> |
| | 72 | }}} |
| | 73 | |
| | 74 | Note: the -X allows X11 forwarding for running X11 applications remotely. |
| | 75 | |
| | 76 | For example, to login to CORNET node1-2 with the login name "testuser" do the following: |
| | 77 | |
| | 78 | {{{ |
| | 79 | # ssh -X testuser@128.173.221.40 -p 7002 |
| | 80 | }}} |
| | 81 | |
| | 82 | To login to CORNET node1-3 with the login name "testuser" do the following: |
| | 83 | |
| | 84 | {{{ |
| | 85 | # ssh testuser@128.173.221.40 -p 7003 |
| | 86 | }}} |
| | 87 | |
| | 88 | === Obtaining Remote Access Login Information === |
| | 89 | To obtain a username for the CORNET nodes, please email Dr. Timothy Newman (trnewman@vt.edu). |
| | 90 | |
| | 91 | === Node Software === |
| | 92 | Each node contains the following software: |
| | 93 | |
| | 94 | * Ubuntu Linux 9.04 Client Version |
| | 95 | * GNU Radio 3.3.0 |
| | 96 | |
| | 97 | |
