      @Sanjana,

      Could you please share the output of following commands:?

      cat ~/work/fabric_config/fabric_rc

      cat ~/work/fabric_config/ssh_config

      ls -ltr ~/work/fabric_config

      Thanks,

      Komal

        @Sanjana – Could you please remove this file if it exists ~/work/fabric_config/ssh_config and run the validate_and_config.ipynb  notebook again?

        Please try SSH to VMs via command line and share the error you see if it still fails.

        Thanks,

          @Sanjana – glad to hear that you were able to create a slice successfully, are you still facing errors when you SSH to the VMs?

          Thanks,

            @Sanjana,

            Could you please follow the notebook: jupyter-exanples-1.6.*/configure_and_validate.ipynb to ensure your configuration is correct? Please try creating a slice after that and let us know if you still run into errors.

             

            Thanks,

              Good morning Nagmmat,

              This looks like a config issue – specifically incorrect/missing project id. Could you please verify your config using the notebook jupyter-examples-1.6.*/configure_and_validate.ipynb?

              Please let us know if you still run into errors.

              Thanks,

              Komal

                Good morning Bruce,

                This error can be ignored. We will fix this in the next version.

                Thanks,

                  Hello Bruce,

                  This is because of an incompatible API change. If you are running JH container, please remove any entries in `/home/fabric/work/fabric_config/requirements.txt’ and restart your JH container via File -> Hub Control Panel -> Stop My Server -> Start My Server.

                  Compatible versions:

                  JH 1.5 => fabrictestbed-extensions==1.5.6

                  JH 1.6 => fabrictestbed-extensions==1.6.2

                  Thanks,

                  Komal

                    @Vaiden

                    You slice is in state ModifyError For any further modifications to your slice, you need to run the following commands:

                    slice=fablib.get_slice(name=slice_name)
                    
                    slice.modify_accept()

                    Regarding the Authentication Error. Please check if you Bastion key has expired and SSH keys are setup properly. You can use the notebook config_and_validate.ipynb to update/validate SSH keys and your config.

                    Snapshot of Slice State:

                    Slice Name: ServiceX_NDN_Proxy_tcp_4nodes Slice ID: 61c1d373-b3b6-472f-a34a-3dd6dac8c809 Project ID: 7a5adb91-c4c0-4a1c-8021-7b6c56af196f Project Name: MF

                    Also, looking at /tmp/fablib/fablib.log would provide more information for the failure cause for Authentication error.

                      Hi Manas,

                      Thank your for bearing with me. I think I finally have a fix for the issue. I have applied the patch on UCSD and STAR for now and have not been able to reproduce it there.

                      I would appreciate if you also try at these two sites and share your observation. Hopefully it works consistently now.

                      Appreciate your help!

                      Thanks,

                            Hi Robin,

                            Acheme is right. Management Network only supports SSH via bastion node and basic ICMP packets. We do not recommend conducting your experiments with Management Network.

                            Please consider modifying your experiment where you are also requesting a local network (L2Bridge or FabNetv4/FabNetv6) since all your VMs are on the same site. Setup your Segment routing using the data plane network instead of the management network. There are several examples available under Networking  in the start_here.ipynb

                            Also, I am enclosing a sample notebook, which requests the VMs and connects them with local L2 Network(IPv6). You can use this as a base and setup Segment Routing on the Data Plane interfaces. Please let us know if you have questions or run into any issues.

                            NOTE: Please rename the notebook from .jpg to .ipynb as the forum doesn’t allow attaching files with .ipynb extension.

                            Thanks,

                            Komal

                              Worked with Vaiden to clean up JH container and also shared the complete back up with him.

                              He also wasn’t able to view his slices created via account linked to older email. Applied a patch on CF to address that. He is able to list the slices now.

                              Thanks,

                                Hi Manas,

                                I noticed some of your slivers are in Closed state with the error: Last ticket update: Redeem/Ticket timeout

                                I applied a patch to address this last night. Could you please delete this slice and try again? We are monitoring the system to see if the patch addresses the issue. As of now, we do not have a consistent way to reproduce this problem. Please keep us informed if you run into this again.

                                Thanks,

                                Komal

                                  Hi Manas,

                                   

                                  I sent you updated notebook with the email. Some more improvements from the last version. Bit easier network configuration. I was able to create a slice on UCSD with this. Could you please try this and let me know how it goes?

                                  Thanks and Regards,

                                  Komal
