Problem connecting to Postgres from Windows

I encountered this error when I tried to connect with pgAdmin running on Windows 7 to a Postgres instance running on an Ubuntu 14.04 LTS.

Postgres error 1

It seems my ip address was not cleared to connect to the server. I had to edit on the ubunte server the /etc/postgresql/9.1/main/pg_hba.conf file.

Run

$ sudo nano /etc/postgresql/9.1/main/pg_hba.conf

Add your ip address range.

Postgres error 2

$ service postgresql restart
