Very great tool Martin!
I cannot understand exactly the way to do what I want. I've tried it in
my own personal computer at home (with only 1 NIC, vr0).

1) Sniffing the traffic in very big chunks of time/data (1GB)

$ daemonlogger -i vr0 -c 1000000000

2. Replay the traffic on the same NIC

$ daemonlogger -R daemonlogger.pcap.1196961141 -o vr0

To check the re-injection process I quit the ethernet wire and launch a
tcpdump instance at the same time I lauch the step number 2; I think the
tcpdump should show traffic, so it's completely localhost traffic.

$ tcpdump -i vr0 -v

...but no traffic is showed.

¿It means that the re-injection process is incorrect?
¿How to do it?
