What does the postgres log say ? ... work through each of the 8 points that mapserever helpfully spits out and post the results back if you can't find an answer.

Hi list,
I am starting with mapserver, but have a very important error and I have
no idea how to put it to work. I doesn't even know if I did it before
but here is the problem:
I am trying to access a postgis layer with the mapserver 4.4.2 and via
browser the return of server was:
msDrawMap(): Image handling error. Failed to draw layer named 'bairros'.
msPOSTGISLayerOpen(): Query error. couldnt make connection to DB with
connect string 'user=postgres password=post dbname=dbpotgis
host=192.168.0.15 port=5432'.
Error reported was 'could not create socket: Permission denied '.
This error occured when trying to make a connection to the specified
postgresql server.
Most commonly this is caused by
(1) incorrect connection string
(2) you didnt specify a 'user=...' in your connection string
(3) the postmaster (postgresql server) isnt running
(4) you are not allowing TCP/IP connection to the postmaster
(5) your postmaster is not running on the correct port - if its not on
5432 you must specify a 'port=...'
(6) the security on your system does not allow the webserver (usually
user 'nobody') to make socket connections to the postmaster
(7) you forgot to specify a 'host=...' if the postmaster is on a
different machine
(8) you made a typo
I hope someone could help me. Nobody did before.
Sincerely
Ezequias
