Very strange EWA issue

[mattyb]

This is actually a follow up issue to this post:

http://forums.nextpvr.com/showthread.php?t=40898

I now have very intermittent access to the EWA through the localhost:port/gbpvr/guide address. If I set to the port to 7647 it will work for 2-3 days, then it'll shut me out - ie. I get an "Internet Explorer can't find this page" error. So then I'll change my port to 8081, and that'll work for another few days and then I'll get shut out again.... then I'll change it to 8082 and the same thing happens.... then 8083 etc etc. The interesting thing is that after 8083 I can put it back to 7647 and it'll work again, then I can go through the sequence again and get the same results.

It's like something is overwriting my port access in this range after a period of time. I don't know what it is for the life of me.

Any suggestions??

A stab in the dark...

Have you tried using the IP address

Code:

http://IPAddress:port/gbpvr/guide

or maybe

Code:

http://IPAddress:port/gbpvr/guide2.aspx

There is something running on your host machine that is monitoring port access and then blocking it.....that is all I can think of.

I noted in the other thread about Firefox having a built in port blocker....you indicated above that you got an IE message.....are you using IE or the IE Tab plugin for Firefox?

[mattyb]

UJB: I'm using IE.

ACTCMS: I'll try your suggestion the next time I get blocked... prob won't be long.

[UncleJohnsBand]

What kind of firewall software are you using? Standard Windows, McAfee, Norton, something else?

[mattyb]

Standard windows firewall - and it's turned off.

Is there any to detect what might be blocking the port access?

I tried the netstat.exe utility included with windows but I couldn't find anything blocking 7647, 8081, 8082 or 8083. Though I'm not very experienced with this type of problem so wasn't entirely sure what I was looking for.

Thanks.

I just thought of something.....when you change the port the GBPVR config app restarts the recording service.....I wonder if your service is simply crapping out or if the web server within the service is getting hung up.

Next time it happens look at your running services and see if gbpvrrecordingservice is running....if not start it. If it is, restart it. Then see what happens.

I restart my gbpvrrecordingservice daily at like 8:30 a.m. since I was experiencing periodic crap outs myself.

Let me know.

[mattyb]

That worked. Though I seemed to get a few error messages when attempting to stop and restart the service. The error was along the lines of, "The service could not be stopped/started. The system did not return an error...."

But when I browsed to the previously "broken" port 7647 - it worked as normal.

So is there a way to automatically stop and restart the service once a day? How do you have that set up?

Thanks!!

I created a batch file called gbpvr-recycle.bat that contains the following:

Code:

taskkill /IM GBPVRRecordingService.exe /T /F
wait 5
net start "gb-pvr recording service"
exit

The first line uses the command utility that is built into Windows to force the recording service to stop. /IM indicates the image name of the service to kill /T is to stop all associated child processes and /F is to force it to stop.

The next line uses a utility I found a long time ago (attached) that simply waits x seconds....I set mine to 5 to allow the recording service to end. Just stick the wait.exe file in your windows\system32 folder.

The next line is the line that restarts the recording service itself.

The next line exits out of the batch file.

I setup a scheduled task to run the batch file each day at 8:30 a.m.

This should work for you.

Excellent. Thanks UJB.

I've implemented the batch file and it ran this morning without a hitch. I think this could be it. I'll continue to monitor over the next while - if you don't hear from me take it as good news!

Appreciate all your help.
