Hi Tyler.
Very good article indeed. I am already running a router on arch linux myself on an APU1D4 and custom intel motherboard with dnsmasq,unbound and shorewall.
I came across your article while searching for a way to visualize network data.
I tried the instructions on elasti.co but I am unable to set it up and getting nowhere.
Would it be possible for you to post how you set it up on arch linux? The second machine where I want to send netflow data is also running arch.
Than you.
