I am working on an Arch Linux machine with an ethernet interface
eth1. I have created the interface
ifconfig and given it a dummy hardware address (
00:01:02:03:04:05). When I send a UDP packet to a server application running on a remote server machine, I get back the right response. But then I see an ICMP Destination Unreachable going out from the
eth1:0 interface ip address. How can I mute this ICMP message? I have tried different mac addresses and set up an arp cache on both client and server machines without success.
Appreciate any help and thanks in advance.
