      @travisdh1 yes.

      Makes it difficult to see weather there are peering-point issues between you and the mirror sites.

      edit: Yes, I've seen networks block distribution mirror sites before. So much fun trying to get those fixed.

        But on the very same network, just a different host nothing is blocked. I could of course look at the firewall to see if something was changed. But if changes were to be made, I think I would've been made aware.

        And every mirror is blocked. It's as though this device itself is blocked.

          Try ping -4 google.com
          It’s probably using ipv6 instead of ipv4

            Will test that in a moment. The restore is going.

              No change.

              And the backup from yesterday has no change either. Grr. . . I don't want to rebuild this VM. . . going further back.

              It isn't mission critical either, just irritating.

                Are you using NetworkManager? If so, turn that shit off.

                  Try adding 127.0.0.1 to /etc/resolv.conf

                      No change with adding the loopback.

                        @DustinB3403 : The fact that you can ping the gateway/router by name and IP makes me suspect it's the firewall.
                        AFAIK, there is nothing on a linux box that would allow it to distinguish between LAN and WAN when performing lookups.

                          the firewall, OR the default gateway is messed up. Check the routes on the VM.

                            @scottalanmiller I have 1 route on the VM, and its a mirror image of the route on the working VM, with the exception of the device name, and IP.

                                @DustinB3403 : Yes, but that doesn't mean the firewall doesn't have a rule (or is a Sonicwall -- see my old post) to block outbound on WAN from that IP.

                                  Double check mac address so you don't have two VMs with the same. That and conflicting ip addresses can cause some strange effects.

                                    Clear arp caches and Mac address tables on your gateway or firewall sounds like a Mac address conflict at the gateway

                                      Just for dirt, try changing the ip assigned to the problem machine and re-initializing the MAC address on the virtual NIC... feels like the edge device is blocking internet access or it's being blackholed on the way out... has anyone been testing content filters or other security solutions on the network?

                                            Different VM networks defined on the VM for the host?
