Sorry to be a bother, but ...
To recap. I have an ethernet port that's wired to a HDTV tuner that converts OTA HDTV to ma4 and streams it down the cable to a program that collects and stores it. All of this is known to work under Fedora 17. No so under Fedora 19. FirewallD is stopped.
The ethernet port has a ifcfg script with
HWADDR="E8:40:F2:05:DE:1C"
BOOTPROTO=none
IPADDR="198.168.20.5"
but is otherwise as created by Anaconda.
To test the interface, one asks the tuner to say what connections it has, hdhomerun_config discover. This is the basic interface. Tracking this with Wireshark, I see:
Frame 1: 62 bytes on wire (496 bits), 62 bytes captured (496 bits) on interface 0

I interpret this as saying that I sent 20 bytes of data via the UDP protocol from 198.168.20.5 to anybody on the 198.168.20 subnet. As I received no response, presumably that's not what I wanted to do.
Is this significant? I can ping 198.168.20.5 successfully, but Wireshark does not see any packets.
Thanks.
