Make sure you typed in the correct passphrase for the ssh keys you have generated at the Geni Portal.
If you need additional assistance , please email genidesktop-admins@netlab.uky.edu




After login , i see my slices , but it says "No Resources Present" even though i have slivers reserved.

You may have the wrong Aggregate managers selected, or they system automatically picked some for you which are not correct. You need to manually select the Aggregate managers you have used for this slice, so that the Genidesktop knows who to communicate with in-order to get information about your slice and nodes. Follow the arrows to set the AMs appropriately. Then select the slice using the checkbox and perform the "Update Status" operation again on that slice.

My Slice status says "MIXED". What should I do ?

Your slice may have had resources from more than one aggregate. When you had used the Genidesktop to "Initialize/Instrumentize" your slice, you may not have had all your Aggregate Managers selected in the AM list selection. But there is hope of recovery. Perform the following operations to bring the state of the slice to a recognized state.

  1. Find the AMs at which you believe your resources are reserved.
  2. In the Genidesktop mouse over the word "MIXED". You should see something like
            {"GN0": "CREATED","GN1":"INITIALIZATION_COMPLETE"}
    
            Assume for this example, that GN0 belongs to KY-IG and GN1 belongs to Utah PG.
    
    This indicates that the "Initialization" operation was performed on the nodes that match the AM to which the node "GN1" belongs. The ranking of the states are :
        0 - CREATED   (least)
        1 - INITIALIZATION_IN_PROGRESS
        2 - INITIALIZATION_COMPLETE
        3 - INSTALLATION_IN_PROGRESS
        4 - INSTALLATION_COMPLETE
        5 - INSTRUMENTIZE_IN_PROGRESS
        6 - INSTRUMENTIZE_COMPLETE  (highest)
    
    
    If your slice details (when you mouse over) has any of the _IN_PROGRESS states, then this may not be recoverable and you may have to delete the slice and start over.
  3. Change the AM selection for this slice to the one with the least state. In our example from (2) GN0 is in the CREATED state which is the least. So we set the AM to KY-IG using the method mentioned here
  4. Perform the "Update Status" operation on the slice. And then perform the "Initialize/Instrumentize" operation to bring the nodes at KY-IG (as per my example) to the "INITIALIZED" state (which is the state my nodes at Utah PG are in)
  5. Change the AM selection for this slice again to set both the AMs this time.
  6. Perform the "Update Status" operation on the slice. You should a valid status this time . If the problem persists please email genidesktop-admins@netlab.uky.edu for help





My Slice status says "ERROR". What should I do ?

Bring your mouse over the work "ERROR" and see what the tool-tip message says.

  • If you see a message "Hostname does not exist", it means that the rack at which you have created your resources has a slow or misconfigured DNS. The hostnames records for you nodes has not been propagated to other DNS servers. You may have to wait a while and then try to perform the "Update Status" Operation. We have seen certain Instageni racks taking around 30 mins for the DNS hostnames to work.
  • If you see a message "Hostname is not responding (timeout or socket error)", it means that the mentioned host/node has a problem with network connectivity or the ssh daemon is no running. Things may not work until the Control Framework errors are fixed. Please contact the GENI Help folks.
  • If you see a message "Authentication for hostname at port", it means that the mentioned host/node has a problem the ssh daemon. It just could be that your slice is not yet in a ready state of just became "Ready" within the last minute or two. If this error persists even after 5 minutes of your slice being in a READY state, try to login to this problematic node using your desktop and the ssh program.
    If you succeed then it could be an error on our part : please email genidesktop-admins@netlab.uky.edu for help
    If you fail then it could be an error on our Control Framework : please email GENI Mailing lists for help





My SSH windows and graphs don't show up/work

Did you see a pop up tab/window in your browser before you were taken to the Genidesktop page with the graph and SSH menus. If not, then that could be the problem. These services run on the GN Node under apache's web server that runs using a self-signed certificate. This has to be accepted by you when presented in the browser.
