FIX "mythtv has died" message

Basically you need to downgrade pluto-dcecommon as follows:

wget http://deb.linuxmce.org/ubuntu/dists/lucid/beta2/binary-i386/pluto-dcecommon_2.0.0.45.12062726126_i386.deb
sudo dpkg -i pluto-dcecommon_2.0.0.45.12062726126_i386.deb
reboot

Set DB password to make mythfilldatabase running

Grant all previliges to mythtv user and set password as shown in /home/mythtv/.mythtv/mysql.txt

Make sure “DBHostName” is set to “localhost” in /etc/mythtv/config.xml

Example:

<Configuration>
  <UPnP>
    <MythFrontend>
      <DefaultBackend>
        <!--
Set the <LocalHostName> hostname override below only if you want to use
something other than the machine's real hostname for identifying settings
in the database.  This is useful if your hostname changes often, as
otherwise you'll need to reconfigure mythtv every time.

NO TWO HOSTS MAY USE THE SAME VALUE
-->
        <DBHostName>localhost</DBHostName>
        <DBUserName>mythtv</DBUserName>
        <DBPassword>mythtv</DBPassword>
        <DBName>mythconverg</DBName>
        <DBPort>0</DBPort>
      </DefaultBackend>
    </MythFrontend>
    <UDN>
      <MediaRenderer>698eda30-c349-4ae9-bc7c-ed00eca7043e</MediaRenderer>
    </UDN>
  </UPnP>
</Configuration>

mythweb

mythweb white page

If you get a white page on mythweb, a possible reason is wrong settings for mysql connection.

Make sure you set the right mysql values in /etc/apache2/sites-enabled/mythweb.conf

setenv db_server        "localhost"
setenv db_name          "mythconverg"
setenv db_login         "mythtv"
setenv db_password      "PASSWORD"

Can't save settings

Maybe you can't save channel settings. This happens because of apache and suhosin settings. Check your apache log

tail -f /var/log/apache2/error.log

If you get an error like this:

.. PHP Warning:  Unknown: Input variables exceeded 5000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0, referer: http://dcerouter/mythweb/settings/tv/channels

Increase the values in /etc/php5/apache2/php.ini as follows

max_input_vars = 15000;
[suhosin]
suhosin.post.max_vars = 15000
suhosin.request.max_vars = 15000

The value to set depends on the number of channels listed

Asterisk

ISSUE

/var/log/asterisk/full shows following warning:

[Jun 19 20:41:02] WARNING[16548] chan_sip.c: Got 423 Interval too brief for service 083339277431@tel.t-online.de, minimum is 240 seconds

FIX

mysql -u root asterisk -e "INSERT INTO ast_config (cat_metric ,var_metric ,commented ,filename ,category ,var_name ,var_val) VALUES ('0', '21', '0', 'sip.conf', 'general', 'defaultexpiry', '240');"

Adds the defaultexpiry value to the asterisk DB. For “Deutsche Telekom” the should be < 240

CUPS and Airprint

Someone wrote a nice python script to generate a *.service file for avahi

Install required packages

sudo apt-get install git-core python python-cups

Download script using git

git clone https://github.com/tjfontaine/airprint-generate.git

go to the downloaded folder, Execute command to generate *.service file of existing printers

cd airport-generate/
python airprint-generate.py

Copy *.service files to /etc/avahi/services/

cp *.service /etc/avahi/services/

Edit /etc/cups/cupsd.conf

sudo nano -w /etc/cups/cupsd.conf

Add this line

# CUPS AIRPRINT
ServerAlias *

edit /etc/cups/printers.conf and comment out “AllowUser” line. This allows every computer in the network to print! It was required for Airprint to work because of permission problems

#AllowUser USER

restart cups

sudo service cups restart
