Post subject:  Newbie bad shutdown question:
I had a bad shutdown, and now I get this error:

"could not connect to the master backend server -- is it running? Is the IP address set for it in the setup program correct?"

I know there's got to be some relatively easy fix, but being a newbie I have no iea what it is.

Any help here would be MUCH appreciated.

(BTW when it IS working its great!)

Essentially heres the situation: The computer locked up during a paused tv show and then the restart button on the case got pushed which manually disconnects power and restarts it. Obviously it didn't go through proper shutdown procedures.


Please Help: Thanks.

From the GUI hitting Alt-3 should restart the backend. This is equivalent to running /etc/init.d/mythtv-backend restart as root.

I have just gone through an install of r5e50 and I'm seeing this same message:

Could not connect to the master backend server -- is it running? Is the IP address set for it in the setup program correct?

I've tried Alt-3 but nothing seems to happen.

I'm not being silly here, but could sparky and bLatch list their capture cards please. I have a theory involving R5E50 + PVRx50 + other capture card(s).

Thanks

Actually the backend restart problem is well understood. The script that starts it is getting fooled by an out of date status file. On a clean shutdown this file is removed, however, if the shutdown is messy and the old file is not removed it can make the script think that the mythbackend daemon is already running.

sparky.watson - what do the following commands show:
Code:
pgrep -fl mythbackend
ls -l /var/run/mythtv/mythbackend.pid && cat /var/run/mythtv/mythbackend.pid

Well, actually, since I had this problem, I grabbed a copy of R5D1 and installed that.

I'll try R5E50 again tomorrow evening.

Alright, reinstalled using R5E50, have not gotten the "Could not connect..." message. Still have a problem with the remote (Silver), no response. It was working under R5D1 last night. During the this install and the previous time I installed R5E50, I got this:

Which Hauppauge remote do you have?
...
c. Silver remote (A415-HPG)
...
Stopping lirc daemon: lircmd lircd.
Starting lirc daemon: lircd.
You can re-run this script anytime.
As root:/usr/local/bin/lirc-reconfig.sh
irexec: could not open config files /root/.lircrc and /etc/lircrc
irexec: No such file or directory

Neither of those files exist currently. I have re-run lirc-reconfig.sh, get the Stopping/Starting messages and that is it. Neither before nor after a reboot does the remote work.

Also, I cannot watch TV. Under R5D1, it looked fine. After installing R5E50, I was able to get a really bad picture (looked like 2 channels were interlaced) but after poking and proding, I just get a blank screen and then back to the menu. I did run TCL_M2523_SOMETHING_E_fix.sh but has not helped.

I dunno if you still need this but I'm using a PVR-350 capture card, and Alt-3 fixed it right up for me.

(key to other newbie's like me Alt-3 really means alt+F3...)

like I said dunno if that info is still needed

Sparky - did you fix the DEVICE setting in /etc/lirc/hardware.conf to point to /dev/lirc0?

For the picture thing try changing the capture resolution.

See the Upgrade Hints posting for more. Even if you did a scratch install the known changes and know issues sections contain a lot of valuable info. http://mysettopbox.tv/phpBB2/viewtopic.php?t=13108 Both of these are covered there.

I have now set DEVICE="/dev/lirc0" in /etc/lirc/hardware.conf and after a reboot, still no remote. When I do an ls -l /dev/lirc*, the only thing listed is /dev/lircd

Sound wasn't working, found:
Run: alsaconf
Add: "include /etc/modprobe.d" to /etc/modprobe.conf
Reboot
Now, I've got sound.

As for capture resolution, where do I change that? I found resolution settings under Recording Profiles. Is that the right place even for "Live" TV? Picture now looks decent but freezes after about 1 minute, becomes non-responsive. I can still putty into the box from WinXP... Still working on this.

Is there something other than a reboot that can be done at this point?[/quote]
