I'm having another minor problem with running tcpreplay in an infinite loop.
I want to write a wrapper for tcpreplay that uses a time specification
rather than the number of loops. My idea was to run tcpreplay on an
infinite loop then send the CTRL-C signal to end it. However, even when I
run tcpreplay directly, and press CTRL-C, the loops continues. Here is
exactly what I am running on the command prompt:
sudo ./tcpreplay --topspeed --loop=0 --intf1=eth0 capture.pcap
Thanks
