sorry here is the actual script command
#build/MoonGen examples/icmp-arp-responder.lua 0 10.3.3.249
MoonGen was run on DPDK box with ip address 10.3.3.9 on dpdk0 interface
here is the tcpdump I run at the target server that has ip 10.3.3.249:
09:50:36.300333 arp who-has 10.3.3.249 (ff:ff:ff:ff:ff:ff) tell 10.3.3.249
09:50:36.302757 arp reply 10.3.3.249 is-at e8:ea:6a:06:1b:1b
why the arp request source ip is 10.3.3.249, not 10.3.3.9
it seems pingResponder in icmp-arp-responder.lua isn't properly running?

This script needs two cores: one for the master core and one for the slave. (This could be optimized by replacing launchLua() with a direct call, but it doesn't really matter).
No idea why your NICs NUMA association shows up as "-1", it shouldn't do that. Which Linux distribution are you using?
A bad NUMA mapping could indeed cause RX to fail on some systems. Other scripts works because they don't try to receive packets.

DPDK interfaces do not have IP addresses.
