Welcome to another boot2root / CTF this one is called Gibson. The VM is set to grab a DHCP lease on boot. It doesn't matter what your local subnet is, as long as you keep away from the subnet. You will see why soon enough...

Once again, I'll offer some hints to you:

  • SSH can forward X11.
  • The challenge isn't over with root. The flag is not where you expect to find it.
