xubuntu

Register a new VM​

  • Note the hardware compatability. If you have a heterogeneous esxi environment with older versions, make sure you pick a version that will be supported by all hosts.

  • storage should be on the BASEVM datastore

Install the Virtual Machine​

Some considerations

  • The Base VM needs to be useable by range-users. For this reason it include a sudo account with a well known password
  • This account can be tweaked after the fact with ansible.
  • For purpose of this lab we will use the username range-user. The password is up to you but for purpose of the demo, I'll be using r@ng32022
  • After rebooting, disconnect the CDROM from your vm by changing it from Datastore ISO to Host device

Run the helper script for xubuntu, ubuntu desktop or sever​

Some of you are like, why aren't you using templates? The answer is that you cant create a linked clone from a template. Linked clones are used for speed and have a significantly lower impact on storage (If you turn off automatic updates)

  • Turn off ipv6 on this VM, it was interferring with dns resolution

  • Make sure to look at the desktop script. You can also find a script for servers that does not bother to install chrome and uses the non desktop version of vmware tools.

    • Chrome and Chrome remote desktop is preinstalled so that students can use this box as a means to go directly into their environment from the internet.
    • VMWare Tools is installed
    • SSH Server is installed
    • SSH Certs are reconfigured
    • the MachineID is truncated, if you don't do this duplicate DHCP ip address occur

    wget https://raw.githubusercontent.com/gmcyber/RangeControl/main/src/scripts/base-vms/ubuntu-desktop.sh
    chmod +x ubuntu-desktop.sh
    sudo ./ubuntu-desktop.sh
    rm ubuntu-desktop.sh
    shutdown -h now

    Take a powered off snapshot called Base​

    • Never turn this VM on again if you are planning to use if for linked clones. Modifying this VM will make any existing clones linked from it unusable.
