| Post subject: | Backend Slave |
I am trying to get a master backend/frontend to work with a slave backend/front end. I followed the scant instructions here: [url]http://www.mythtv.org/docs/mythtv-HOWTO-9.html#ss9.3[url] I tried googling for a better tutorial/faq but couldn't find one. I keep getting the error message: Connection to master backend server timed out when I try to view live tv. I have verified over and over the IP Addresses. I have my computer on static DHCP. Is there something I am missing or is there a good tutorial for slave/master setups? Thanks. |

Can you ping the master from the slave? Did you configure MySQL on the master to listen and allow netowrk connections?http://mysettopbox.tv/doc.html#frontend |

Ping is working fine. I can connect to the master backend's MySQL from my Windows box with Control Center and view all tables. |

The IP fields in mythtv-setup on the master backend should both be the MBE's IP. On the SBE it should be it's IP and the MBE's IP. Is this so? Are both running the same version of mythtv? |

The Setup: Master Backend IP: 192.168.0.101 Slave IP: 192.168.0.102 Master Setup: System IP: 192.168.0.101 Master Backend IP: 192.168.0.101 Slave Setup: System IP: 192.168.0.102 Master Backend IP: 192.168.0.101 Both are KnoppMyth R4. I don't have R4 V2 yet  .

Now that R4 V2 has been released, I decided to try this again. My first try worked. The slave would connect to the master fine! However, the slave was getting its video from the master. So I edited /usr/share/mythtv/mysql.txt to be: Code: DBHostName=192.168.0.101 DBUserName=mythtv DBPassword=q2dUSRDq DBName=mythconverg # Set the following 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 (or futz with the DB) every time. # TWO HOSTS MUST NOT USE THE SAME VALUE # LocalHostName=mythtv-upstairs I get the following error when I run mythfrontend: Code: Unable to connect to database:
Driver error was [1/-1]: 0MYSQL3: Unable to connect Database error was: '192.168.0.102' (Using password: YES) couldn't open db By the way, the MythTV documentation says this file is at /usr/local/share/mythtv/mysql.txt but it is at /usr/share/mythtv/mysql.txt on KnoppMyth. |

I forgot to mention that I can connect to MySQL on 192.168.0.101 (master backend) from my Windows box through Control Center. |

On a slave backend, I don't think you edit mysql.txt. |

Myth TV's documention says that you are supposed to http://www.mythtv.org/docs/mythtv-HOWTO-9.html#ss9.3. No matter what, the slave was getting the live video from the master instead of from itself. Is this normal?[/list] |

From my understand, yes it is normal. If you are watching live TV and have a tuner in the slave, then it should use that before using one on the master. |

Ok, I finally figured out what was wrong. I should have known better  . Anyway, I was editing mysql.txt with Windows. The new line characters in Windows text files are different than Linux.
Anyway, its working now! I checked out whether the slave should stream its own video. It will not do this by default. It is normal for a slave to start live streaming based on the card id. I couldn't find the way to change this. There is a way and once I find it, I will post it here. |

One more tip. KnoppMyth is using "q2dUSRDq" as the password for the mythtv MySQL user. This is different than in previous versions that used "mythtv". Keep this in mind as you make your mysql.txt file. |

"q2dUSRDq" is only used on the MBE itself. To connect over the network "mythtv" is the password. |
