Both copies refused to run unless /usr/sbin/tcpdump existed. Debian and Ubuntu install it as /usr/bin/tcpdump, so the rogue DHCP detector never ran there and the probe reported its tcpdump check as failed. Resolve tcpdump through PATH and the standard system directories with CommandUtils::find_executable, run the resolved path, and match that path when the capture process is killed at the end.
