      Tejas,

      From the screenshots you attached, it looks like your diskspace is full. You might also consider removing unused files. That might be related to the problem you’re having, second screenshot reveals that problem.

      Best regards,
      Mert

        Hello Tejas,

        You can try again. It might be due to the hosting cloud platforms scaling in progress at that time.

        Best regards,
        Mert

          For some reason all your VMs management network interfaces are offline. If you share the notebook with us, we can understand if something in the flow might be causing an issue.

            Can you send the slice ID?

              Dear Experimenters,

              Network problem is resolved. FABRIC-TOKY is available for experiments.

                Problem with the SSH bastion keys is resolved. All of the new keys are added to the bastion hosts. Please, try your logins and let us know it you have any problems.

                  We are still working on a resolution for this issue. Bastion key for the user id ‘jbalcas_0000188368″ could not be ingested into the bastion hosts yet (along with others posted on this thread). Once the issue is resolved, all bastion keys will be pushed in to the bastion hosts. Updates will be posted.

                      Dear Experimenters,

                      Maintenance is completed, FABRIC testbed is open for the experiments. A detailed message about the changes will be released.

                          Dear Experimenters,

                          As previously communicated over this thread as well as announcement emails, we will perform a general maintenance on the FABRIC Testbed this week. We will start deleting all slices by 11pm EST. Updates will be posted to this thread.

                            Arash,

                            I created a ticket for this. We can use the ticket for the steps for your experiment. You should receive emails from FIP-1522

                              IPv6 address of the specific mirror site is causing errors, they don’t have an operational web service on that IPv6 address, therefore IPv4 address of the service should be used. On an IPv6-based FABRIC node, this can be possible by putting an entry for the NAT64 converted address. Specifically as follows (this is against FABRIC’s NAT64 service, similar address should be possible against nat64.net’s space):

                              echo "2600:2701:5000:5001::ac5d:9e3c mirrors.jevincanders.net" >> /etc/hosts 
                              
                              

                              Another problem came out a “non-free” package within kali-linux-everything, sources.list had to be modified. I’m adding below the complete set of steps. Also I added your ssh public slice/sliver key to the VM, so that you should be able to login with the following if needed for review.

                              ssh -F <path to SSH config file> -i <path to private sliver key> debian@2001:5e8:ff00:ffff:f816:3eff:fe43:4688

                                VM management networks of the FABRIC nodes (used for ssh’ing into the VMs and for external connectivity to the public internet) are either IPv4 or IPv6.  I’m not sure how/if this information can be found out, so I’m just adding below a list.

                                • Sites with IPv4 management network: TACC (will be changed to IPv6 in July), UCSD, FIU, SRI, BRIST, TOKY
                                • Sites with IPv6 management network: STAR, MAX, MICH, MASS, UTAH, NCSA, WASH, DALL, SALT, GPN, CLEM, GATECH, LOSA, NEWY, KANS, ATLA, SEAT, PRIN, INDI, PSC, RUTG, CERN, AMST, HAWI, EDUKY

                                  I’m not sure specifically what errors you were getting, I will outline some info from my test slice.

                                  On my trial (on an IPv6-based FABRIC node (PSC)), one mirror (mirrors.jevincanders.net) was causing download problems (their IPv6 address seemed not working). There may be some workarounds with pointing the IPv4 address of the mirror site to a NAT64 address in /etc/hosts. In order to overcome this problem, using an IPv4-based FABRIC node (eg. FIU) can be convenient. I could not find out if Debian 10 or Debian 11 should have been used for this conversion, I tried with Debian 11 on FABRIC-FIU and it worked fine with some issues. (I used kali-linux-default instead of kali-linux-everything, there was a conflict about a package that I did not have time to check further)
