I apologize in advance if this is a stupid question, but I really don't have a good background knowledge about networking. I did try to google all this stuff, but I simply couldn't find anything specific to my needs, or maybe I am just searching the wrong way because my lack of knowledge.

Anyhow, I am trying to network boot a Raspberry Pi 3 as part of a project at college. I managed to do it on my home network (Raspberry Pi 3 as client and a Raspberry Pi 2 was used as the server), but now the problem is that I can't do that at college because of the network restrictions. I need to find another way.

I have an old router at home and I was wondering can I do all that stuff with the router connected to power and with 2 Ethernet cables so that 2 Raspberries can communicate over that 'offline' router. Is that even possible and if it is, could you please point me in the right direction? As I mentioned before, I couldn't find anything useful so either I am searching for wrong things or it is not possible the way I thought it might be.

Thank you.

Run a dhcpd like dnsmasq, and optionally avahi/bonjour/rendezvous/bleh (mDNS) on your laptop, and connect the PIs to your laptop via a switch. Set the hostnames of your PIs to foo.local and bar.local, they'll be easy to interact with.

  • thanks, will try that...but it worked the way I thought it might :) The only problem is that it worked on my home router even when it's only connected to the power and not on my old router. Don't know why is that.

  • Either set static IPs or run dnsmasq. Check that the old router serves DHCP leases.
