By default PostgreSQL is configured to be bound to “localhost”.
As we can see above port 5432 is bound to 127.0.0.1. It means any
attempt to connect to the postgresql server from outside the machine will be refused.
We can try hitting the port 5432 by using telnet.
In order to fix this issue we need to find postgresql.conf. In
different systems it is located at different place. I usually search for
Open postgresql.conf file and replace line
Now restart postgresql server.
Here we can see that “Local Address” for port 5432 has changed to 0.0.0.0.
Let’s try to connect to remote postgresql server using “psql”.
In order to fix it, open pg_hba.conf and add following entry at the
The second entry is for IPv6 network.
Do not get confused by “md5” option mentioned above. All it means is
that a password needs to be provided. If you want client to allow
collection without providing any password then change “md5” to “trust”
and that will allow connection unconditionally.
Restart postgresql server.
You should be able to see list of databases.
Now we are able to connect to postgresql server remotely.
Please note that in the real world you should be using extra layer of
security by using “iptables”.
