@Paul Previously I was mainly following the instruction from the URL you just listed: https://learn.fabric-testbed.net/knowledge-base/logging-into-fabric-vms/ . Also, I have been trying to figure out the difference between that link and configure_enviroment.ipynb in jupyter-examples-rel1.3.3. It would be great if you can offer me some insight into the difference between them. Meanwhile, I apologize for not mentioning that there was one time that I can actually ssh into the node. Are you sure that I absolutely need to delete all the key pairs etc and start from scratch?
@Paul I have tried both methods and here are the issues that I am running into. I ran the configure_enviroment and when I try to ssh into a host, it reports that “Warning: Identity file /home/fabric/.ssh/fabric_bastion not accessible: No such file or directory. yyuan76_0000024961@bastion-1.fabric-testbed.net: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).” I checked the link you recommended for me and configure_enviroment.ipynb and I believe that none of them involve in creating files in the ~/ssh directory. Should it be concerning
@Paul I have run through the Hello,FABRIC example and it yields the same error where I can create a slice but cannot ssh into the nodes. I suspect it has something to do with the keys because the error message is “Permission denied (publickey,gssapi-keyex,gssapi-with-mic).kex_exchange_identification: Connection closed by remote host”. Regarding the key, I have created the key this August at the earliest and should not expire.
@YaxueGuo Hello, Yaxue, I deeply appreciate your insight regarding the token. However, it still does not work properly even when I switched to a new browser.
Here is a general question: what do I need to do to make sure the sliced jupyter notebook created is not dead?
It ends up showing me that I have 4 dead slices (I probably iterate that notebook 4 times) with the name I gave. What would you do in this case?
May I ask what’s the difference between the instruction of https://learn.fabric-testbed.net/knowledge-base/logging-into-fabric-vms/ and configure_enviroment.ipynb?
Hello,
So you are saying that I should create a slice using the “create slice” notebook under start_here.ipynb even if I can create a slice in Fabric Portal web UI because I cannot know the IP address of the slices I was creating. Am I correct?
So after a couple of times trying to ssh, I got the exit message as shown in Follow_Up#1 and Follow_Up#3. Is there something I should be making changes about? The second problem happens when I do the troubleshooting section of this link: https://learn.fabric-testbed.net/knowledge-base/logging-into-fabric-vms/ . My error report is shown in Follow_Up#2.
I don’t know what’s happening but in incognito mode, it is still receiving “400 : Bad Request. OAuth state missing from cookies”
So I have cleared any cookies and still get “400 : Bad Request. OAuth state missing from cookies” message.
