By "the loop continues" you mean tcpreplay does not exit? Can't
imagine why that is- tcpreplay has never suppressed any of the
SIGDIE/QUIT/etc signals and only uses SIGUSR1 to pause and SIGCONT to
continue. Going to need more information about your system and what's
going on (a screen cap of your terminal after the CTRL-C would help)
Anyways the way I'd do things is as root run this script:
#!/bin/bash
tcpreplay <args>
pid=`jobs -l tcpreplay | cut -d " " -f 2`
sleep XXXX
kill -9 $pid
Replace <args> with your arguments and XXXX with the number of seconds
to let tcpreplay run
