Agents not working

how did @hansmuff achieve it here

This is not an area I know much about but missing loopback and getting one configured somehow has been raised many times in past 2 years or so and there are probably other forum posts relating to that

He created a VIMAGE jail which is an experimental type of jail that has its own dedicated network stack. You can think of it like a VM, but it doesn’t have any performance penalties. VIMAGE has a lot of issues that are being worked on right now. It should be quite stable/reliable in FreeBSD 11.0. I hope to see it no longer considered experimental soon.
