@ Alex: Thank you for your help. I succeed in loading without any problem my qgis project through qgis from my station hosting the postgrsql server.
But, as you say, i can't do it from another station. From other station, the error message that i put previously. Another thing. I opened my qgis project thnks to an editor. And i notice one sentence probably interesting: <datasource>dbname='world' host=localhost port=5432 user='image' password='cactus' sslmode=disable key='gid' srid=0 type=POINT table="world_capitals" (the_geom) sql=</datasource> So i tried to edit this line. I replaced host=localhost by host = ip server. In vain... Regarding your example : For instance my ip server is 192.167.40.92, why you said the host ip should be something like 192.168.1.100? For remind, i repaste below, my pg_hba.conf current settings : --------------------------- # IPv4 local connections: host all all 192.167.40.0/24 trust # IPv6 local connections: host all all ::1/128 md5 --------------------------- According to you where are the mistakes in these sentences? Thank you. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Qgis-Postgis-impossible-to-open-a-project-tp5065048p5090717.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
