Post subject:  Frontend can't connect to database
I have R5A10 installed on my backend and am trying to set up a frontend using 0.17. When running mythfrontend I get a message that says "Myth could not connect to the database." and in the console I get:

2005-03-21 13:53:37.392 Unable to connect to database!
2005-03-21 13:53:37.392 No error type from QSqlError? Strange...
couldn't open db

I can however connect to the database using

mysql -h ipaddress -u mythtv -p mythconverg

from the box I am trying to use as my front end without any problems.

Any ideas?

I forget, is R5A10 before or after the upgrade to 0.16? If before, you can't mix different versions of the FE and BE , they changed the protocol...

According to the Sytem Status page on the backend box the version is 0.17.20050131-1

Did you make sure you placed the proper IP address to your master BE in mythtv-setup? look at your mysql.txt files too and make sure they're correct (just do a locate mysql.txt and it will show you where they are).

Double checked the IPs in mythtv-setup both where 192.168.1.100 in the general tab. All mysql.txt files where set to 192.168.1.100 except the one in /etc/mythtv . I changed that one restarted the backend with /etc/init.d/mythtv-backend restart . Still get the same error.

Just tried running the frontend off the cd on the box I am trying to install the frontend on and it worked, well I had to manualy load the snd_emu10k1 module then it worked. This is the same cd that the backend was installed from.

Whoops! Finger fumble... Make that the upgrade to 0.17, however that's clearly not the problem if both are running 0.17.

I upgraded the backend to R5A12 in hopes it would fix my problem and it still can not connect. Any one have any ideas what to try next?

Wish I would have noticed them before. Can any one tell me how to load the drivers? The frontend is a Mandrake 10.1 box.

Got it to work. Needed to download and install libqt3-mysql rpm

This probably would have been resolved much quickier if you stated that the frontend was on Mandrake. Details people, details.
