Just a question to see if this is possible. Multicast over my lan is slow enough that unicast ends up being a better option. We’re talking pushing maybe 60 Mbps. I’m sure this is something to do with the config of my Cisco switches, but unless it’s a super quick fix, that’s neither here nor there.

I’m wondering the following:

I setup a physical fog server, replicate over the images from my master server. Import all my hosts into it as well. I plug this server into a switch, and plug all my clients into that switch. I plug the switch into the network, and update my DHCP settings to point to this new, physical fog server.

clients boot. get to the join multi-task option on all clients. disconnect the switch from the network, effectively isolating it. join the task on all of them.

Image hopefully goes as fast as it can.
