GENI Desktop: "SSH Error hostname does not exist" but I can ssh using the same hostname without issue

[Derek Christopher O'neill]

My slice is doneillExp1. GENI desktop is telling me that the hostname for my GEMINI global node at Illinois (pcvm2-3.instageni.illinois.edu) does not exist yet I'm able to ssh into it using that hostname just fine. Does anyone have any idea what can be going on here?

[Derek Christopher O'neill]

Nevermind, after refreshing for the seventh time that problem has resolved itself but now I'm getting a failed to initialize error on the same slice.

Hi Derek,
   From what i see, the DNS for the illinios rack seems to be flaky. It resolves the name for the GN node for 5 min and then just stops resolving. I had seen this behaviour before at the Northwestern rack too but for a different reason.

So my advice here is to avoid the Northwester and Illinois rack for the time being until i get this issue resolved with the Racks admins.

cheers,

Hi Derek,
 There seems to be a problem on the nodes at the illinois rack.
Can you please add  the following string on a new line in "/root/.ssh/authorized_keys" to all the illinios rack nodes in your slice.

ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAtel3SoMV/Uk9dKMqrFiWHCibL8nl69Dxgqu3+HimQFmpvVk/mGEx7DwfuEP4uZS1cGPtkd81OoBhKaWclUwDngKrP7+Ljm4MZlV40sV7N/FUUKm47VHArDXsR5p2cLWgEdUMnEk88KTqPA+MOQunLZmqaJgDHyXQ0ptsLJqc84BDFmCwHbAn+wbcnK+DTpBhgX1Tzy/HO+yOI+iLR5eRDQ4DRBZzNJS177Cz9m3WHmteM0zPhxm3lerflXukkXzaHPlM3s5fpqQxuRYiwh41a1kzKqzgmnfyurR4URKB1qJT26KarFMG32GhODDvovmoikT8qDuByNZPqFIH0igidQ== www-data@portal

This way i can login and check what went wrong.

Hi Derek,
 I had tried your experment just too wher ethe problem was. It looks like the DNS at illinois takes about 30 minutes to stabilize. Once i tried  30 minutes after the experiment went ready, the instrumentation worked fine. I am taking this issue up the dev folks, but thought I'd let you know how things went

Thanks, should be done.

Hi Derek,

   What you have is a mixed state that has never been tested before. I could suggest you a hack but am not sure it will work. So the safest way is to delete this slice and start a fresh.

Thanks for all of your help. Right now on GENI desktop my slice status is mixed so I can't initialize or instrumentize it. It says the status of my GPOlab GN is Initialization_Complete but the Illinois GN is status Created.
