tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on dummy0, link-type EN10MB (Ethernet), capture size 262144 bytes

What does ./tcpdump -D print? Perhaps the dummy0 device isn't the only device and also isn't a device on which any network traffic is being received or sent; ./tcpdump -D should show all the devices on which you can capture.
