Are you sure the BE is running as root? Are you using systemd? What is in<br>
your service file?<br>
<br>
</blockquote>
<br>
Sorry - sent email to Mark by accident:<br>
<br>
Systemd? Yes<br>
<br>
[root@mythmaster ~]# pstree -p | grep system<br>
systemd(1)-+-ModemManager(578)<wbr>-+-{ModemManager}(604)<br>
|-systemd-journal(366)<br>
|-systemd-logind(584)<br>
|-systemd-udevd(397)<br>
<br>
<br>
Not sure how to find out if BE is running as root. If you mean under the<br>
mythbackend.service file - ( vi /usr/lib/systemd/system/mythba<wbr>ckend.service)<br>
-- then I tried both here:<br>
# systemd changes execution from the calling user (possibly root) to this<br>
user<br>
# if you have permissions problems or obscure errors try logging in as<br>
mythtv<br>
User=mythtv<br>
#User=root<br>
<br>
I had commented out "user=mythtv" and put root instead - but that didn't<br>
change anything.<br>
<br>
What's in it - what was default i believe:<br>

<br>
The normal way to run mythbackend is to have it run as the mythtv<br>
user. I have never run it as root, but it may not be intended to run<br>
that way and it could cause complications. You do have to have a<br>
mythtv user on the system for that to work, but it does not have to be<br>
a login enabled user. The default is to also have a mythtv group (to<br>
which the mythtv user and any user that runs mythfrontend must<br>
belong). Then you put all the things that mythbackend needs in the<br>
/home/mythtv/.mythtv directory, such as config.xml and the channels<br>
directory with all the channel icon files. If you want to have just<br>
one config.xml file, then you can put that in /etc/mythtv and ln -s to<br>
it from all the /home/<username>/.mythtv directories.<br>
<br>
This is what a good config.xml file looks like (copied from my test PC<br>
which was installed as a 0.28 system a few months ago):<br>
<br>
<Configuration><br>
<Database><br>
<PingHost>1</PingHost><br>
<Host>10.0.2.12</Host><br>
<UserName>mythtv</UserName><br>
<Password>********</Password><br>
<DatabaseName>mythconverg</Dat<wbr>abaseName><br>
<Port>3306</Port><br>
</Database><br>
<WakeOnLAN><br>
<Enabled>0</Enabled><br>
<SQLReconnectWaitTime>0</SQLRe<wbr>connectWaitTime><br>
<SQLConnectRetry>5</SQLConnect<wbr>Retry><br>
<Command>echo 'WOLsqlServerCommand not set'</Command><br>
</WakeOnLAN><br>
</Configuration><br>
<br>
There are some other things that can be added to the config.xml file<br>
by mythfrontend, but those settings are what is wanted by mythbackend.<br>
Fill in the correct names, addresses and password for your system. You<br>
may or may not need the pinghost option set on - I have it on because<br>
I am connecting via the external IP address for the PC, not localhost,<br>
so I do not want mythbackend to try to connect until that address is<br>
pingable.<br>
<br>
There are different older formats for config.xml that also seem to<br>
still work, but I believe the above is the current format.<br>
<br>

I beg to differ. This is mine:<br>

That LocalHostName entry is important. /Some/ of the checking that reads the file uses the hostname (jade) for the 'Hostname' entries in the database and /some/ of the checking uses the fully qualified domain name [FQDN] (<a href="http://jade.example.com" rel="noreferrer" target="_blank">jade.example.com</a>).<br>
<br>
(I forgot during a recent upgrade and ended up with the backend using one and the frontend using the other. Hilarity ensued? Er, no.)<br>
<br>
It is best to make certain that the system knows what the host is called by specifying a LocalHostName entry. It doesn't matter what it is; you can use the hostname, the FQDN or anything else that is unique on your system.<br></blockquote><div><br></div><div>Is there a way to do this?

<br>
Oh, and in mythtv-setup, make certain that the backend has the *same* IP address for backend and master backend entries. Putting hostnames or FQDNs there can cause other problems.<span class="HOEnZb"><font color="#888888"><br>
