Unable to connect PostgreSQL to remote database using pgAdmin

I installed PostgreSQL on my local server (Ubuntu) with IP 192.168.1.10. Now, I'm trying to access the database from my client machine (Ubuntu) with IP 192.168.1.11 with pgAdmin.

I know I have to make changes in postgresql.conf and pg_hba.conf to allow the client to connect. Could you please guide me?

pgadmin postgresql

In linux terminal try this:

  • sudo service postgresql start : to start the server
  • sudo service postgresql stop : to stop thee server
  • sudo service postgresql status : to check server status

I didn't have to change my prostgresql.conf file but, i did have to do the following based on my psql via command line was connecting and pgAdmin not connecting on RDS with AWS.

I did have my RDS set to Publicly Accessible. I made sure my ACL and security groups were wide open and still problem so, I did the following: sudo find . -name *.conf then sudo nano ./data/pg_hba.conf then added to top of directives in pg_hba.conf file host all all 0.0.0.0/0 md5 and pgAdmin automatically logged me in.

This also worked in pg_hba.conf file host all all md5 without any IP address and this also worked with my IP address host all all <myip>/32 md5

As a side note, my RDS was in my default VPC. I had an identical RDS instance in my non-default VPC with identical security group, ACL and security group settings to my default VPC and I could not get it to work. Not sure why but, that's for another day.

Connecting to PostgreSQL via SSH Tunneling

In the event that you don't want to open port 5432 to any traffic, or you don't want to configure PostgreSQL to listen to any remote traffic, you can use SSH Tunneling to make a remote connection to the PostgreSQL instance. Here's how:

  1. Open PuTTY. If you already have a session set up to connect to the EC2 instance, load that, but don't connect to it just yet. If you don't have such a session, see this post.
  2. Go to Connection > SSH > Tunnels
  3. Enter 5433 in the Source Port field.
  4. Enter 127.0.0.1:5432 in the Destination field.
  5. Click the "Add" button.
  6. Go back to Session, and save your session, then click "Open" to connect.
  7. This opens a terminal window. Once you're connected, you can leave that alone.
  8. Open pgAdmin and add a connection.
  9. Enter localhost in the Host field and 5433 in the Port field. Specify a Name for the connection, and the username and password. Click OK when you're done.

Check your firewall. When you disable it, then you can connect. If you want/can't disable the firewall, add a rule for your remote connection.
