问题
I get the following error when attempting to connect to the Postgres instance on my server.
Access to database denied The server doesn't grant access to the database: the server reports FATAL: no pg_hba.conf entry for host "fe80::2d93:af94:879c:4fa%12", user "postgres", database "postgres", SSL off
I have tried the three obvious solutions found HERE. Namely I attempted Syed Aslam solution found in that^ link.
I tested that I was restarting the service correctly by removing some config to break my local pgAdmin III connection. I have checked if my firewall was blocking the connection by temporarily turning it off.
Can anyone help me figure out why I am getting this error?
Postgres 9.4.1
pgadmin III version 1.20
Windows Server 2012 (host)
Windows 7 (trying to connect from this to the host)
回答1:
It turns out that I had an IPv4 as the IP address in my entry for the pg_hba.conf. After changing it to an IPv6 version like this:
IPv4 = 0.0.0.0/0 IPv6 = ::/0
It all worked as I would have expected. The comment from user_0 and the documentation found HERE cleared it up for me.
Obviously the answer works in reverse if you're using an IPv6 when you should be using an IPv4.
