Here is the problem : System : Fedora Core 5 Application server : Apache (comes with Fedora base installation) 1. I could not connect to postgresql in php code whicih uses pear packet DB. Here is the error code : DB Error: connect failed [nativecode=Unable to connect to PostgreSQL server: could not connect to server: Permission denied Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?] ** pgsql://postgres:bbmprens@xxxxxxxxx/prens 2. By the way I can connect that db from an other machine which the system is Windows XP and program is default PgAdmin. 2. Alsa I can connect and use from a windows machine with the sama php code that connects to the dbms which works on the Fedora Core 5. 3. The user and password are tested by using pgsql command, in command prompt. Thanks...
