In the pg_hba.conf file, I have the following entry: host db1 client1 192.168.150.234/32 md5 Now the problem is: The client having IP 192.168.150.234 is trying to use phpPgAdmin, but is unable to connect. The corresponding config.inc.php has this entry: $conf['servers'][0]['desc'] = 'PostgreSQL'; $conf['servers'][0]['host'] = '192.168.150.234'; $conf['servers'][0]['port'] = 5432; $conf['servers'][0]['defaultdb'] = 'db'; ---------------------------------------------------- If the entry is: host db1 client1 192.168.150.234/0 md5 Then, any client (client with any IP address) can log in as no MASK specified.
