Adding a jumpuser on XVM

There is a script called add_jumpuser. You will need:

Username for the user
IP of the machine (see below for allocation)
ED25519 pubkey from the user

Once you have all of this, just run on XVM (note the single quotes around the ssh pubkey):

/root/scripts/add_jumpuser.sh USERNAME RPI_IP 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIE29EOVCl0/WjknAoEEEZSPUyCWQKNoXX2HCC123456 some1@host'

IP allocation

1-9: XPUB main servers
10-99: shared machines used by the whole course (for admin or lessons or multi-user projects/libraries/etc)
100-254: personal and/or grad projects machines
