I am pretty new to everything that is database management, remote connection etc... And I need this for a university project.
I have a local postgreSQL database on my Windows computer, which I access through localhost. What I want to do now is connect to this database using my laptop (which is in the same WLAN, don't know if that helps).
I changed the file pg_hba.conf, and added host all all 0.0.0.0/0 md5 and host all all ::0/0 md5. Also in the postgresql.conf file, there is one line listen_addresses = '*' which was the default, but as I understand it it is what it needs to be so a non-localhost can connect to the database.
How can I do this? On my laptop I tried running psql and for the server I put the IPv4 address of my PC(where the local database is stored), but it doesn't connect (Connection timed out)
Need access to the Odoo postgresql DB (via pgAdmin 4). Even with the changes made to pg_hba.conf it won't connect.
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all [Our Networks IP]/32 md5
host postgres odoo [Our Networks IP]/32 trust
host SLWK_PRE-PROD_DB odoo [Our Networks IP]/32 md5
# IPv6 local connections:
host all all ::1/128 md5
Is my format wrong or am I missing something else? I've tried connecting via bash as a super user and it won't let me query stuff either.
I've already tried editing the pg_hba.config with different settings but no avail.
When trying to connect via pgAdmin 4 the following error appears:
FATAL: no pg_hba.conf entry for host "[Our Networks IP]", user "odoo", database "postgres", SSL on
FATAL: no pg_hba.conf entry for host "[Our Networks IP]", user "odoo", database "postgres", SSL off
Probably, you need to restart PostgreSQL? You need to reload its configuration after making any changes to apply them.
The easiest way to do it is to restart PostgreSQL service:
service postgresql restart
You can also use pg_ctl:
sudo su postgres
pg_ctl reload
Or you can do inside PostgreSQL itself:
psql -U postgres
postgres=> SELECT pg_reload_conf();
Solved the issue by putting the AWS EC2 instance IP in the pg_hba.conf in the Unix-domain socket fields. Was putting my configuration in the TCP/IP part of the pg_hba.conf.
I cannot connect to my postgresql instance remotely on port 5432. Connection times out. I cannot connect remotely using psql, pgAdmin or telnet. I feel like I have everything configured correctly. Postgresql has been restarted several times with these settings. Remote connection works fine.
What could I be missing?
netstat:
postgressql.conf
pg_hba.conf:

in short you have to the following steps
1. Add the following line to the pg_hba.conf server. This will allow connection from “192.168.xxx.xx” ip-address (This is the client ip)
# vi /var/lib/pgsql/data/pg_hba.conf
host all all 192.168.xxx.xx/xx trust
Change the Listen Address in postgresql.conf
# grep listen /var/lib/pgsql/data/postgresql.conf
listen_addresses = '*'
Test the Remote Connection
You just need to change the method md5 to trust and and enter the address as 0.0.0.0/0.
Open the config file
vi /var/lib/pgsql/data/pg_hba.conf
Insert the following line
host all all 0.0.0.0/0 trust
Maybe it will work.
I use a Windows 10 machine with Virtualbox 5.0.16 in which Ubuntu 15.10 is running. The network adapter is a Bridged one with the name set to Intel(R) Dual Band Wireless-AS 3165. The promiscuous-Mode is set to allow all VMs and the host and the underlying checkbox is checked (cable connected).
In this Ubuntu, I run a PostgreSQL 9.4.5 instance in which I configured both the postgresql.conf and pg_hba.conf files.
In the postgresql.conf file, I have well set this line:
listen_addresses = '*'
And in the pg_hba.conf, I have following lines at the bottom:
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 0.0.0.0/0 md5
host all all ::1/128 md5
host all all ::/0 md5
host all all 192.168.1.13 md5
host all all 0.0.0.0/0 md5
Currently, the ip address of my host machine is (ipconfig command and wireless) 192.168.1.13 and the guest machine is (ifconfig command) 192.168.1.4
When using pgadmin from the host machine to connect to the guest machine, I get following message: FATAL: no pg_hba.conf entry for host "192.168.1.13", user "postgres", database "postgres", SSL off
I tried to connect to my host to guest via ssh but I get a "Network error: Connection refused" message. Maybe this is a key insight of my issue?
The ping works in both directions.
Thanks to #DanielVérité.
The command show hba_file showed me the pg_hba I was actually editing was not the right one. I edited the one in /etc/postgresql/9.4/main folder while the one used by postgreSQL is /opt/PostgreSQL/9.4/data
