      Have you setup any routes for the ping to work ?

        Hi,

        I looked at logs on one of the failed nodes and found that the last command before the node failed was

        “sudo /usr/sbin/ldconfig /home/ubuntu/openssl/build/lib64/”

        This command results in the breaking of the sshd daemon running on the machine, thus causing you to loose your ssh connection. A reboot would fix the ssh because the library you built is not loaded.

          The docker images have been updated at all of the racks with the fixes requested.

              Yes i understand that. But as i mentioned in my post https://learn.fabric-testbed.net/forums/topic/kali-machine-failing-on-post_boot_config/#post-8105 . You will have to do those modifications to get it to work.

                Hello Nirmala,

                I believe you missed providing some details regarding the above setup. Guessing from the output you pasted above I think you are trying to install frr using instructions from https://deb.frrouting.org/ . The error you posted above is because that package does not have a release for Kali Linux. All the repos point to Debian or Ubuntu. When you run teh setup commands mentioned on the FRR webpage , it creates a apt repo file in /etc/apt/sources.list.d/frr.list. The name of the OS in that file is shown as “kali-rolling” .

                I am guessing Kali Linux is based off debian 12 (bookworm) . So if you replace the word kali-rolling with bookworm, you apt commands to install the packages should work.

                  Hello Nirmala,

                  We have corrected the image at the WASH site and are updating all other sites with the corrected image. This process should be done by EOD today. You can start using WASH in the meantime

                    Hello Nirmala,

                    I believe we have a faulty disk image for Kali. Please bear with us while we get this resolved. It may be a few days before we get back to you.

                          Aha. The cuplrit is the group ownsership on your home folder. This must have been changed somehow.

                          drwxrwx— 12 ubuntu root 4096 Dec 2 18:17 /home/ubuntu

                           

                          run the command

                          sudo chown -R ubuntu:ubuntu  /home/ubuntu

                           

                          That should fix the issue.

                              Can you please post the output of
                              ls -lad /home/ubuntu

                              ls -la /home/ubuntu/.ssh

                               

                              The can see from the ssh log that the ownership of home directory is the issue

                                Can you please grab the logs using

                                sudo journalctl -r -u ssh >/tmp/ssh.log

                                 

                                and then email help@fabric-testbed.net with the ssh.log file attached .If pullout the file is not possible then just run

                                sudo journalctl -r -u ssh

                                and copy the few recent lines that will help us debug the issue.

                                  One likely cause is if the disk is full. Please check that too.
