RHEL 6.5.
I have a capture of UDP packets, generated this way:
tcpdump -nnXs 0 -i eth1 udp port 26477 and dst 233.86.230.111 -w ITCH.pcap
I've moved this file over to a dev VM, and want to replay it through my server for debugging. My server does not (yet) have the capability to read pcaps directly, so I want to rebroadcast this via UDP.
However, I want the packets to both be sent and recieved on the same box. That's because this VM is on the production network, and I don't want to flood the network. I'm fine replaying these packets through the loopback interface (in fact, that's preferred). I can configure my server to read from any mcast group/port, off of any interface.
Is there any way I can replay these packets so that they don't leave the local machine, and read them in my server?
tcpreplay won't work apparently because the packets won't be seen on the sending box.
