[Skimmertalk] Moving a trio of RP over to a separate LAN - how to assign static fixed IP to the Red Pitaya

[Jeff Blaine]

My key question is how to assign a static IP to the RP Skimmer receiver?

The background is this...

I have 3 RP now and in a busy contest condition, the combined network 
utilization of the 1G link is pretty significant.  Not nearly the point 
where it swamps the network, but it's easily 30-50% of network capacity 
in these conditions.

The computer I use for the skim server host has 2 LAN cards built into 
the motherboard.  So I'm thinking that I could probably hang the 3 RP 
and a switch off of the 2nd LAN port which would isolate all that 
Skimmer chatter to the 2nd LAN port and keep it all from my primary 
LAN.  As all the skimmer apps (as well as HSSDR) run on that computer 
and no where else in the shack, I won't need to bridge the two Ethernet 
connections on the motherboard.

There is no gateway bound traffic and I don't want to hang a router off 
this mini-network just to provide DHCP so I'm thinking that I probably 
could make this work cleanly if I can figure out how to assign the 3 
individual RP with static fixed IP.

Appreciate any advice there.  And if any other of you fine fellows may 
have been there, done that as well.
