VBoxManage ... Could not find a registered machine name

[rripley]

I am trying to setup NAT on my Linux Guest... I created a virtual machine named "linux", running Ubuntu. Host is Windows Vista.

When I execute VBoxManage from the Guest OS, it complains it cannot find the machine name. Is there something I am missing?

rripley-laptop:~# VBoxManage setextradata "linux" "VBoxInternal/Devices/pcnet/0/LUN#0/config/guestssh/Protocol" TCP

The machine name is not on the guest. It is on the host. You need to run it from there.
