Unable to connect to Search Server

Hello,

I have been working all day trying to solve this error without any luck. I have reinstalled and reconfigured OpenSim, WAMP, Joomla, and JOpenSim several times today without any luck. I have been through the manual from front to back trying to see if I missed something. Any help would be greatly appreciated. Thank you.

Here is what I am working with:

- Windows 7 Home Premium
- OpenSim v0.7.4 (Grid Mode)
- Joomla v2.58
- JOpenSim com_opensim v0.2.5
- jOpenSim.Profile.dll
- jOpenSim.Search.dll
- WAMPServer v2.2e (PHP v5.4.3 Appache v2.2.22 MySQL v5.5.24-32b)

Console Error Message OpenSim.exe:

02:29:26 - [jOpenSimSearch]: (3) Unable to connect to Search Server http://localhost:8888/components/com_opensim/interface.php. Exception System.Xml.XmlException: Root element is missing.
02:29:26 - [jOpenSimSearch]: initDataUpdate returned error: Unable to search at this time.

Hi jman

"Root element is missing" is many times an indication of some error and/or notice output of php during xml response. Is there anything written in your access_log and/or error_log (of the webserver jOpenSim is installed)?

You also can enable debugging for "search" in jOpenSim global config and see what is turning up in your /components/com_opensim/interface.log (specially something about "response for searchDataUpdate").

[reminder]Dont forget to disable debugging at the end and empty interface.log again[/reminder]

Thanks for the quick reply foto. Here are the results from the logs. I only enabled debug for the search. I had this working great the other day but then I accidentally screwed up my WAMP installation and had to start from scratch.

Hi jman

Dynamic domain names can allways cause some problems, but for me it looks more like either your webserver is not listening on port 8888 or this port is not enabled in your firewall.

I have port 8888 open on my router and all other firewalls disabled. Using an online port checker, it shows it as open. The same goes for the ports that opensim uses.

Using the generic opensim services pack, everything works just fine. However, I would rather use jOpenSim because of it's functionality.

If it helps any, I have OpenSim configured to use two database. Robust.ini uses a database called opensimgrid and GridCommon.ini uses a database called opensim. The website uses a database called website.

All together there are three databases.

In jOpenSim Global Config it is setup this way:

Hostname: jman2012.dnsdynamic.com
Post: 9000

OpenSim database: opensim database
OpenSim Grid database: opensimgrid database

Joomla is installed in the root directory of the webserver (www).

Everything under Settings / Addons is checked except for Money and Inworld ID.

On another note, it looks like none of the jOpenSim services are working. They are all producing errors.

When I had this running before, it was running under HyperGrid mode before I decided not to use HG and move to just using grid mode. I completely reinsalled OS, joomla, and jOpenSim when I switched over.

After many hours of messing around with my router to fix this problem without any luck, I decided to examine the jOpenSim's interface.php file that kept saying that 192.168.0.1 was being denied from accessing.

Just by luck I came across this line:



After changing that line to obtain the IP address from an external source instead of just spitting out my local IP address, all the problems went away. All I did was upload a PHP file called "myip.php" to one of my external hosted websites with the following code in it:



And I changed:



to:



I hope this may help anyone that comes across a similar problem. The only downside is that since you can't control if the external website is up or down, you will end up with a problem of not being able to obtain the IP address if it is down. In this situation, you may need to add a server status check like this:



There may be other and better ways to do this, but this helped solve my problem.

another downside is this is using fsockopen , some people dont like to enable this on their server, a alternative would be to use curl
