      I just tested access from a TACC VM and  http://linux.mirrors.es.net/ubuntu was reachable. If you’re still having problems, then we need to learn about the specific information from your VM and docker image creation. Please let us know if you still need help on this.

            I created a FABRIC ticket on Jira – FIP-2180

            If you received an email from this ticket, please “reply to” the email to confirm that we can use it for further communication. If you did not receive an email from the ticket FIP-2180, please notify here on this thread.

              That’s not the output that I’m looking for.

              The issue that you are reporting has similarities with some previous cases. I just confirmed the status of WASH FPGA for the specific CMAC status. If you want to run your experiment with the WASH, it’s available now and you can check how traffic will work. If it’s  working case, then I can perform the same intervention on KANS FPGA. In case, you consider using WASH for testing this, you will be able to fit a VM with 4-8 cores and 100GB disk size (available memory is plenty).

                Network services are verified to be working across the sites.

                FPGA itself can be the concern. Can you share the output of
                command = 'cd esnet-smartnic-fw/sn-stack/ && docker compose exec smartnic-fw sn-cli cmac status' ?

                  As an update,

                  according to our tests and observations since reporting the issue to the hosting site, this issue did not repeat itself and we conclude that it’s resolved.

                    This problem is caused by some issues within the hosting site’s and/or its upstream provider’s IPv6 routing, specific for the EDUKY node. Work is in progress to address this issue, but we don’t have a time yet for a resolution.

                    FABRIC provides the following VM images that have docker (and openvswitch) installed in them
                    – docker_ubuntu_20
                    – docker_ubuntu_22
                    – docker_ubuntu_24
                    – docker_rocky_8

                     

                    On the other hand, the issue may present itself for some other specific servers. As a workaround, the following may help for a temporary solution.

                    Get the IPv4 address of the server
                    get.docker.com –> 108.157.150.23
                    download.docker.com –> 108.157.150.36

                    Adjust NAT64 addresses wrt FABRIC’s NAT64 gateway prefix
                    get.docker.com –> 2600:2701:5000:5001::6c9d:9617
                    download.docker.com –> 2600:2701:5000:5001::6c9d:9624

                    Add to /etc/hosts

                    echo “2600:2701:5000:5001::6c9d:9617 get.docker.com” >> /etc/hosts
                    echo “2600:2701:5000:5001::6c9d:9624 download.docker.com” >> /etc/hosts

                    Then, you should be able to reach these sites (routed to their IPv4 addresses through FABRIC’s NAT64)

                                Dear Experimenters,

                                FABRIC-CLEM is back online. VMs are accessible, their PCI devices are re-attached, however IP addresses may need to be re-assigned by the experimenters.

                                We have an issue on the dataplane that is interrupting traffic for L2STS and Layer3 services. We will post updates.

                                  Hello Yuanjun.

                                  I don’t have the details of your slice request, but from the STAR status page on the portal, host resources for hosts that have the RTX6000 GPUs (star-w1 and star-w2) have one GPU available. Host star-w2 has a very little amount of RAM. I checked slice creation on both hosts with their available GPUs and it works well. Just, for the VM that would be placed on star-w2, I selected very small amount of RAM and CPU to fit in it.
