problems with a postgres connection script

Hi I have this script which has problems connecting to the postgres backend. Postgres is running and PHP can see. I have IMP (webmail) working with Postgres on that server OK. This is the output I get on the apache error log: [Tue Nov 7 19:18:22 2000] [error] PHP Warning: Unable to connect to PostgreSQL server: connectDBStart() -- unknown hostname: ultra31, in /space/http/html/pruebas/cargar.php on line 2 [Tue Nov 7 19:18:22 2000] [error] PHP Warning: Supplied argument is not a valid PostgreSQL link resource in /space/http/html/pruebas/cargar.php on line 4 Any ideas? -- "And I'm happy, because you make me feel good, about me." - Melvin Udall ----------------------------------------------------------------- Martín Marqués email: martin@math.unl.edu.ar Santa Fe - Argentina http://math.unl.edu.ar/~martin/ Administrador de sistemas en math.unl.edu.ar -----------------------------------------------------------------
