You want to connect to your postgresql server but you do not get access to the system although the server is listening on port 5432.
In the case your server is listening to the default port and you do not get access, you will have to make changes to your pg_hba.conf file.
On debain you can find this file in a postgres dependent path. e.g.
For information about how to make postgres listen on your network card, which is not the default, you can search in the knowledge base on "Howto make shure postgres will listen on the network".
In your pg_hba.conf file you will find the following:
# "local" is for Unix domain socket connections only
local all all ident sameuser
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
I you want to listen from a full class network 192.168.123.0 with subnet mask 255.255.255.0 you can add the following line:
host all all 192.168.123.0/24 trust
If you restart your postgres server, you will be able to connect from the network.
Restarting can be done with:
invoke-rc.d postgresql-8.3 restart
