This is what I get for TTFM (Trusting The Fine Manual). I did Google and RTFM. Page 6 of the PDF document at the manufacturer's website... http://www.silicondust.com/hdhomerun/hdhomerun_tech.pdf lists the output from a "get help" command ***FOR CURRENT MODELS***. It includes, amongst other items...
/sys/ipaddr dhcp|"<ip> <mask> <gw> <dns>"
On my machine, "get help" produces...
Supported configuration options: /ir/target <protocol>://<ip>:<port> /lineup/location <countrycode>:<postcode> /sys/copyright /sys/debug /sys/features /sys/hwmodel /sys/model /sys/restart <resource> /sys/version /tuner<n>/channel <modulation>:<freq|ch> /tuner<n>/channelmap <channelmap> /tuner<n>/debug /tuner<n>/filter "0x<nnnn>-0x<nnnn> [...]" /tuner<n>/lockkey /tuner<n>/program <program number> /tuner<n>/streaminfo /tuner<n>/status /tuner<n>/target <ip>:<port>
There is no mention of "/sys/ipaddr" ***ON MY MACHINE***. I also remember various people asking on the HDHomerun support forum years ago about IP addresses, and hearing that this model did not have any other addressing options. One correction on the date of my machine. See https://www.youtube.com/watch?v=JXmi-6nVhCM which discusses the exact same model I have. I bought mine in 2010, but the reviewer notes that it won some award at CES2008. Consider it a 2008 model.
Due to the documentation, and lack of mention of DHCP in "get help", I assumed it wouldn't work. However, just for ####s and giggles, I enabled the DHCP server on my router, set the DHCP address pool to 192.168.123.241-to-192.168.123.247, and expanded my local LAN subnet from a /29 to a /28 like so...
config_eth0=" 192.168.123.251/28 broadcast 192.168.123.255" routes_eth0=" default via 192.168.123.254 metric 20 192.168.123.240/28 via 192.168.123.254 metric 0"
Notice the lack of a 'modules=( "!iproute2" )' line. I installed the latest firmware update from the manufacturer's website... (hdhomerun_atsc_firmware_20141124.bin). Lo and behold, it actually works, coming up at 192.168.123.241. This is notwithstanding the documentation and "get help" output, which both say nothing about DHCP. Maybe this was a feature that was backported into a firmware update. Anyhow, I apologize for wasting peoples' time.
Hey we learned something too. I think the idea always was that it should use dhcp. Newer models started allowing static IP, but they all do dhcp. dhcp is complicated though and sometimes compatibility issues happen. When dhcp does not fail, it is very common to default to a link local address of 169.254.x.x, which is certainly what windows does, and apparently also what the HDHR does. -- Len Sorensen
