You might check these two things.
1.  You can edit the postgresql.conf file (not sure where that is on your 
system).
 https://www.postgresql.org/ docs/9.2/static/runtime- config-connection.html
 Uncomment or add the line listen_addresses='*'. You can
 tailor that to be more specific, but try this first.
 
2.  The file pg_hba.conf also controls access.  Look at this:
      https://www.postgresql.org/ docs/9.3/static/auth-pg-hba- conf.html

Be sure to restart the server after you make changes to these files.

Hope this helps,

jdbc postgres driver to access it from a windows client but this is not 
working. If I test the driver on the server it tells me that the connection is 
refused and I should check that the machine is accepting TCP requests.
I have opened the standard port that postgres uses
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5432 -j ACCEPT
iptables -L returnsACCEPT tcp  --  anywhere anywhere    
state NEW tcp dpt:postgres 

this is where I don't know what to check next. A few things that might be 
relevant. If I "ps -eaf | grep post" I see four postgres processes running 
under my username (not postgres), so I think there is a server working. There 
is also a "system" postgresql (version 9.2) which I have connected to 
previously a long time ago. This connection no longer works either and I don't 
really care about that but could be an interfering factor.
If anyone has suggestions about what to check next or solve this I'd be grateful

thanks,Neil

The server itself must be told to allow remote connections.
You might check these two things.
1.  You can edit the postgresql.conf file (not sure where that is on your
system).

https://www.postgresql.org/docs/9.2/static/runtime-config-connection.html
 Uncomment or add the line listen_addresses='*'. You can
 tailor that to be more specific, but try this first.

2.  The file pg_hba.conf also controls access.  Look at this:
  https://www.postgresql.org/docs/9.3/static/auth-pg-hba-conf.html

Be sure to restart the server after you make changes to these files.
