SSH multiple routers connected via switch

Question

I want to capture wireless packets with multiple routers using tcpdump. I can capture wireless packets with just one router but I want to capture with multiple routers simultaneously and send it to a computer.

So, to do this I need SSH to every router. and I need a switch to SSH to routers. Here is an example setup: see

I will be able to start capturing packets and change wireless frequencies simultaneously with SSH connection with every router.

But SSH requires an IP address. As far as I know unmanaged switches does not have a DHCP server. So these routers will not be assigned to an IP address.

So the question is: Can I SSH to routers connected with an unmanaged switch from a computer which connected to the same switch, or do I need a managed switch?

Answer 1

Managed vs unmanaged doesn't matter. It is usually not the job of a switch, in general, to serve DHCP. There are some switches which do serve DHCP, but the vast majority of even managed switches do not.

Instead, this is usually the job of either a router or a dedicated server. If the network doesn't have a router which could do it, then a DHCP server could be run on your own PC – several are available for Linux (e.g. dnsmasq, isc-dhcpd, kea), macOS (e.g. bootpd), and even for Windows.
