Server doesn't listen
The server doesn't accept
connections: the connection library reports
could not connect to
server: No route to host (0x00002751/10065) Is the server running on
host "
192.168.0.76" and accepting
TCP/IP connections on port 5432?
If you encounter this
message, please check if the server you're trying to contact is
actually running PostgreSQL on the given port. Test if you have network
connectivity from your client to the server host using ping or
equivalent tools. Is your network / VPN / SSH tunnel / firewall
configured correctly?
For security reasons,
PostgreSQL does not listen on all available IP addresses on the server
machine initially. In order to access the server over the network, you
need to enable listening on the address first.
For PostgreSQL servers
starting with version 8.0, this is controlled using the
"listen_addresses" parameter in the postgresql.conf file. Here, you can
enter a list of IP addresses the server should listen on, or simply use
'*' to listen on all available IP addresses. For earlier servers
(Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter
to 'true'.
You can use the
postgresql.conf editor that is built into pgAdmin III to edit the
postgresql.conf configuration file. After changing this file, you need
to restart the server process to make the setting effective.
If you double-checked your
configuration but still get this error message, it's still unlikely
that you encounter a fatal PostgreSQL misbehaviour. You probably have
some low level network connectivity problems (
e.g. firewall configuration). Please check this thoroughly before
reporting a bug to the PostgreSQL community.
