    Hello,

    I am trying to set up FOG with an Ubuntu 16.04 LTS Server running on a VirtualBox.

    After reading a guide I followed the instructions and all worked really well until I had to set up a static IP.

    I use the command nano /etc/network/interfaces

    But after editing the files, my Ubuntu server loses connection to the internet.

    I change from
    alt text

    to

    alt text

    The numbers are different, of course.
    The address and netmask stays the same. The gateway and dns-nameservers are found out by using ipconfig /all an my Windows PC.

    Can anyone help me, please?

      Did you happen to notice the differences in subnet between dhcp and static?

      Under dhcp you had a 10.x.x.xx subnet. That makes me think you are using a nat interface under virtualbox and not a bridged network interface.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        With your fog server configured in dhcp mode it would be interesting to compare the output of ip addr show using dhcp vs what you have configured for a static interface.

        Then once you are in static mode see if you can ping 8.8.8.8

        And lastly see if you can ping www.dell.com

        That will properly test your network connectivity.

        Also be aware if you have a virtual box VM.

        1. You must bridge the FOG server nic to the physical NIC.
        2. You install FOG after you have a static NIC defined. FOG does not like the IP address of the FOG server to change after FOG is installed.

          ip addr show
          

          for dhcp
          alt text

          for static
          alt text

          ping 8.8.8.8
          

          for a static IP address
          alt text

          ping www.dell.com
          

          alt text

          My two variants of the interfaces file look like this:
          static
          alt text
          dhcp
          alt text

              I found my mistake

              • The IP was wrong
              • the old VM snapshot had NAT instead of bridged network interface enabled

              Thank you very much for the fast support.
