Hello ! This was a problem with my hosts file :-(
I am very sorry. The two - called "identical" - written programs differs in accessing the db server by name. The machine - a VM - was restored from scratch and contained a mismatch between hosts and postgres config. The message from Npgsql - connection refused - was really right :-( My fault! A BIG SORRY! br++mabra _______________________________________________ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
