Ross,<br>
Thank You for your report about canonical addressing in the Python Bindings.<br>
<br>
I created ticket #13593 upon your finding at<br>
<a href="https://code.mythtv.org/trac/ticket/13593" rel="noreferrer" target="_blank">https://code.mythtv.org/trac/ticket/13593</a><br>
<br>
Could you please apply the proposed patch in this ticket and<br>
restore the database to the canonical IP addressing scheme, like<br>
<br>
| BackendServerAddr | <a href="http://myth.betterworld.us" rel="noreferrer" target="_blank">myth.betterworld.us</a> | barley |<br>
<br>
and run the attached test file?<br>
<br>
The attached test file does not alter yourt MythTv system in any way.<br>
<br>
The file should report instead of an IP address '10.0.0.XXX'<br>
the canonical address of your MythTV system<br>
and report something like<br>
<br>
$ python3 test_canonical_address.py<br>
host : myserver<br>
Master-Backend IP: 10.0.0.XXX<br>
Hash1 : f78f3ddee497d3e8<br>
Hash2 : f78f3ddee497d3e8<br>
host-ip1 : 10.0.0.XXX<br>
BackendServerPort1 : 6543<br>
host-ip2 : 10.0.0.XXX<br>
BackendServerPort2 : 6543<br>
host-ip3 : 10.0.0.XXX<br>
BackendServerPort3 : 6543<br>
<br>
Roland<br>
