To get postgresql running on ubuntu to listen for external connections I did this…

  1. From a terminal window run "sudo gedit" and type your password when prompted.  Gedit opens and you edit the conf files using it.
  2. Edit the file at /etc/postgresql/8.3/main/postgresql.conf and change listen_addresses='*'. This will enable TCPIP connections to the server.
  3. Edit the file at /etc/postgresql/8.3/main/pg_hba.conf and add the following line(s) host    all         all          trust
  4. This will allow tcpip connections (host) on any database (all) for any user (all) for CIDR-address 192.168.0 - any 16 high-level bits (  and authenticates anyone that can connect to the server-no pass (trust) See for details
  5. Add any additional ip address ranges you need to that file
  6. From a new terminal window restart postgresql by typing the following command from a new terminal window... sudo /etc/init.d/postgresql-8.4 restart and type your password...if you setup the configuration correctly you should get an [OK] from the terminal.
I was also worried I would have to learn how to open up an ubuntu firewall but that was not needed. This article helped me... Seth
