[postgis-users] Mapserver and Postgis

[Obe, Regina DND\MIS]

It could be that your webserver doesn't allow outbound connections on
5432 because it has a firewall in front blocking.  As Greg mentioned it
sounds like you aren't connecting at all.

Do you have root access to your webserver?

Gregory,
Many thanks but there is notthing on the  postgresql-Tue.log :-( .

I can start and stop the postgresql without problem. I use postmaster -D

way.

Another thing. How can I ping using mapserver ?
Another thing2:I can log to postgis using ssh connection (as root and 
after as postgres user).
Another thing3:There is no password to postgis ( linux )user. The 
postgis (database) user has yes a password (and I used on the map file)

I hope  you could understand my enviroment.
