Christian, You didn't include the layer definition for the layer that you want to serve as a WMS, so I can't tell if you have a projection block that is reprojecting your data to 4326 from the spatial reference system that it is in.
When I look at the ogrinfo output, it looks like your data is in UTM, or some SRS that uses meters or feet as the units. In your map file, you have set the units to meters, but the extent looks like you are trying to use decimal degrees. You are also stating that your output SRS is 4326 or geographic. I would suggest getting a simple mode=map request working before you try to get a WMS request working. Try commenting out all of the projection information, use the extent values from ogrinfo in your MAP EXTENT. (149532.733262 4061858.514502 246384.733262 4145546.514502) Set the layer STATUS to DEFAULT. Your URL should look something like: http://192.168.1.16:6969/cgi-bin/mapserv?&MAP=/srv/maps/DGIS.map&mode=map I am not sure if you have additional problems, but definitely have a problem with projections and the extent values in your map file. After you get this stripped down version working, you will need to know what spatial reference system your data is in, so you can define a projection block in your layer. This defines the input/native projection for that data, the projection block at the top of the map file defines the output projection for the entire map. If this still gives you problems, you could simplify it even further by creating a layer with one of your geotiffs as the data. This eliminates issues related to the tile index.

I think it is a problem with projections, but I don't know how I should fix it... Anyway I'm not sure that this is the problem, so I give more info about my issue.
