[mapguide-users] Troubleshooting WMS display problem

[Jo Cook]

Dear All,

I have a MGOS 2 server, serving a WMS feed (of the Sheboygan Sample
dataset), sitting on an internal network. I have an MGOS 2.1 server, sitting
in a DMZ, with access to the internal MGOS server. Both servers are running
on Windows 2003 server. The internal server is using the bundled apache 2
web server and the DMZ server is running with IIS. 

My problem is that the MGOS server in the DMZ can correctly display a WMS
layer from a different WMS server (Geoserver) over the internet, but cannot
display the WMS from the internal MGOS server. 

What I have done:
1) Followed the instructions on configuring a wms feature source using xml
files and mapagent. This correctly creates a WMS data connection, and I
create a layer from it. The data connection reports no errors, and I can see
the coordinate system of the data.

2) I have checked that my coordinate systems are all consistent throughout.

3) I have checked the logs on the internal MGOS server and it appears (with
my limited experience) to be logging attempts to access the data, and
reports success. There are no errors in the error log for either server.

4) When I create a map, and try and set the display extents, it defaults to
-180, -90, 90, 180, so I set these as the bounds that are reported in the
properties of the original layer on the internal MGOS server.

5) I have also tried this with a second data source, and the same thing
happens...

I cannot get command line access to the servers to run MGOS in debug mode, 
and at present I don't have access to the MGOS server in the DMZ other than
through the web interface and Mapguide Maestro.

I am aware that this might be more of a networking issue than a Mapguide
issue, but since I can see requests on the internal server that relate to
the web server, I am assuming routing is happening correctly. I am also
wondering if it's because the internal MGOS server is running version 2
rather than 2.1. 

Any tips on debugging this, or indeed fixing it, would be very much
appreciated!

Thanks

Jo
