Then type "sh runs". 59 61 * Go back to GENI Desktop Tab/Window 60 * Make sure the information window is open. 61 * Mouse over the link connecting nodes A and B, and write down the IP address of B. 62 * Make sure the information window is open. 63 * Mouse over the link connecting nodes A and B, and write down the IP address of B. 62 64 * Highlight node A 63 65 * Click on "SSH" 64 66 * Click on "Open Browser SSH" 65 67 * edit file "runc" and replace "IPaddr" with the IP address of B. 66 * Type "sh runc" 68 * Type "sh runc" 67 69 * Go back to GENI Desktop Tab/Window. Observe the traffic window. 68 * You can go to the tab/window for A and type "sh runc" mulitple times. See what happens in the traffic window. 70 * You can go to the tab/window for A and type "sh runc" mulitple times. See what happens in the traffic window. 69 71 70 * Part III: Finish 71 * Teardown experiment 72 === Part III: Finish === 73 * Teardown experiment 72 74 73 75 74 == II.
