Hi, /usr/temp/ has 7777 rights and it is good enough for the MS_ERRORFILE... Short history of my trials: - half a year ago tried to set up ogroutput with no success - read a message about using "temppath" in the mapfile and added that parameter - SHPZIP and CSV outpur started to work and I was happy - but in the same evening the "Failed to open result file" errors came back - never again had a new success with that Linux server - not a single success with several Windows computers - last week tried the new MS4W 3.0.4beta1 on Windows - succeeded to make ogroutput to work for a while - was suspicious and restarted Apache and started to get "Failed to open result" file errors again It can of course be that I am just repeating my own errors but weird is that I have received valid CSV an SHAPEZIP outputs but only for a while. -Jukka Rahkonen-_______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
