[Opensim-users] The very last error

Sat Nov 11 04:45:54 UTC 2017

Note that osgrid opensim.ini does say
...
    ;; if not defined - llRequestURL/llRequestSecureURL are disabled
	; UNCOMMENT AND SET THIS TO YOUR EXTERNAL OR LOCAL ADDRESS TO ENABLE AS NEEDED
    ;ExternalHostNameForLSL = 127.0.0.1
...
	So basicly the same, they are just not using for now the ${Const...  macros, that our master example uses.

Hi,
	In relation to ExternalHostNameForLSL the main difference relative to 0.8.2 is that you do need to set it in Opensim.ini
	If absent, 0.8.2 did used a machine name obtained from the operating system, that did not work in many cases (like localhost on old example didn't).
	The default in 0.9 does set it to the same external host name of the region main http server, now defined at top of page.
	The use of Const|BaseHostname prevents having it set on Opensim.default.ini, as usual for defaults, so it must be uncommented on Opensim.ini, to be active.
	The port will be the main http server port, or the one defined with "https_port" (see Opensim.defaults.ini) in case of a secure connection (as in 0.8.2).
	So for unsecure ulrs your network configuration should also work with 0.9 default, you only need to check the ssl port forwarding if using ssl (again as 0.8.2)
	The option does allow a different hostname, but it also does need to route to the region where the script is running.
	- Port 12046 is SL specific.
	I don't know osgrid settings, and it is possible they consider better to have it disabled by default, for their user base (since it did not work with 0.8.2 defaults for most of those)
	Hope this helps,
Ubit.

Ubit,

Thanks for this information.  Today I upgraded my test region to the latest release that OSgrid puts out which was November 8th, 2017.  Oddly enough they have changed this setting in OpenSim.ini to be:

;# {ExternalHostNameForLSL} {} {Hostname to use for HTTP-IN URLs. This should be reachable from the internet.} {} ;; Hostname to use in llRequestURL/llRequestSecureURL ;; if not defined - default machine name is being used ;; (on Windows this mean NETBIOS name - useably only inside local network) ; ExternalHostNameForLSL = "127.0.0.1"

Apparently they want this feature to be disabled.

I actually use this function on a seldom used object that transfers NPC images between my server and in-world.  I have not tried that particular object for well over a year not so would not have noticed it may not be working.

Strangely enough when looking up the llRequestURL function it says nothing about any configuration parameter needed.  I suspect that is because in SL no user is able to change configuration parameters in the servers.

It is not clear to me how this function could actually work since in my case all my servers are behind my router which is where my host name points to Using port forwarding it directs the inbound requests to the proper computer/server.

The wiki states: Requests one HTTP:// url for use by this script. The http_request event is triggered with the result of the request. HTTP-in uses port 12046.

I don't even forward that port to any server.  How could one server handle the requests for scripts running in different servers behind the same gateway?

With this function disabled, how does this even work?  I must confess I had to be running release 0.8 the last time I used this object.

Tom

Hi
In OpenSim.ini.example (version 0.9 release and above) You can see the line:

ExternalHostNameForLSL = ${Const|BaseHostname}

Uncommented, so the feature is enabled by default.
The fact you don't have it on Opensim.ini, may mean you did reuse 0.8x version...
On the update you should use the new configuration files, changing what you need comparing to old ones (yes a pain i know :( ) So please compare the files and fix (also the other relevant .ini files), or you may have other problems you just did not detected.
BaseHostname for example is now defined at top of the OpenSim.ini in section [Const] (You may change that to other url, guess not in your case)

Regards,
Ubit

I understand it is not an ERROR for the program to operate.

I would prefer not to get into a discussion of what is or is not an error and simply find out what needs to get fixed.

Open sim is obviously checking something and finds it missing.  If I missed something it is my ERROR, if opensim is checking something that should not be checked for then it is an issue for a mantis report.  I suspect it is something I have not configured because it is labeled LSL so probably I ignored it.  Once I got rid of the hundreds of other WARN messages, this last one kind of stood out.

I correct my one sentence of "This is the error." to be "This is the message."  Since the WARN may be telling me of "my ERROR" my post title is correct.

A warning is NOT an error. It is simply letting you  know that a particular function is not available, as it has not been configured.
