there's most likely a firewall in between that drops packages ...

Hello,

did your DB-Server accept connections via TCP/IP, can you connect via psql?

Things to check:

- Is Postgres actually running on the server machine?

- Is it accepting TCP/IP connections on port 5432? - Check
listen_addresses in postgresql.conf

- Is there a firewall somewhere between client and server?

- Can you connect manually to the server using psql?

How exactly are you access Postgres? - psql, pgAdmin, or some other means?

Also, a *lot* more detail would help.... operating systems, Postgres
version, PHP version, whether you're connection on a LAN or over the
Internet, etc etc etc.

Hi Arachna,

[Please keep replies on-list; reply-all should do the job. Thanks!]

Is it possible that your Postgres server is listening on a different
port? If you can, could you post your postgresql.conf?

Also, are you maybe using a firewall locally on your Windows machine
which is blocking PHP?

Hallo,

did yours server listens on other addresses than localhost (I mean the
parameter listen_addresses in your postgresql.conf)?

Kind regards

Sven

Hallo,

ok, do you use the same db-user for pgAdmin3 and your php-script? 

I host pgsql servers on both machines.

the pph code is like this

'

$conn=pg_connect("host=10.162.19.3 port=5432 dbname=postgres user=postgres password=postgresql");

'
