Now any time you want to connect to your remote postgres server, simply start an ssh tunnel, and connect locally using port 2222. Remember, port 2222 is the local port we defined that will pop out on the remote server as port 5432. On the client machine (the one you made the ssh tunnel from), open a new terminal and run the following command: psql -h localhost -p 2222 -U postgres If that worked, then we can test via the SSH tunnel. Note you should run this command using any user except the user postgres (the Linux user postgres should be able to connect even without the above changes). First we can test that we have a working user on the remote server by running the following command using directly on the remote server. What the two lines above do is allow any user to connect to any database on localhost, or via a local socket connection using password authentication.įor the above config changes to take effect we need to restart postgres. So, open pg_hba.conf and then add the following lines: host all all localhost md5 This can be a tricky file to find, on my Centos 6 server it is located in the directory /var/lib/pgsql/9.3/data (note you will need to change 9.3 to the version you are running). The sqlectron-core module has been merged into this package to make development easier and faster, it still using sqlectron-db-core though for the database part. To fix this we can add a couple of lines to the postgres config file: pg_hba.conf By default Postgres won’t allow this, and expects the Linux user bob, not fred, to connect. But for some you will need to ensure that PostgreSQL is configured to allow local network connections and that it will authenticate users as specified on the connection.įor example, if I connect as user fred, but the database user/role I need to use is called bob, then I need to specify user bob on the database login. On the remote server the user will connect to port 5432, the default postgres listening port.įor many setups the above tunnel is enough to allow you to work remotely, and securely. Once the above tunnel is set up you would connect to localhost on port 2222. This is the local Linux user that will make the connection locally on the remote server. Another cross-platform one is SQLECTRON, which is also free and opensource. The last bit,, is the regular user connection used to ssh to the server. GitHub - sqlectron/sqlectron-gui: A simple and lightweight SQL client desktop with cross database and platform support. SQL Operations Studio is a data management tool that enables you to work with SQL Server, Azure SQL DB and SQL DW from Windows, macOS and Linux. The localhost bit between the two port numbers is how the connection will appear on the remote server. The above will bind to port 2222 locally, and appear as port 5432 on the remote server. To set up a simple tunnel you can run something like the following on your client (e.g. I wanted to run pgAdminIII on my local machine and connect to my remote Postgres server, so I decided that using an ssh tunnel would be safer alternative than allowing postgres connections through my server firewall. To the remote server you’ve connected locally on localhost! You can then connect to the port on localhost and the magic of ssh will forward the port securely to the remote machine. your Linux desktop) to a port on the remote server. You basically forward a port from your local machine (e.g. ![]() ![]() ![]() We're still hard work to deliver you more great features and make the app issues free.Using an SSH tunnel is a great way to administer remote services without having to directly expose them to the internet. Please notice the app is in the beta stage yet. In SQL Client we made it easy to choose the right collation by giving you a list of collations already used in the current database.Īlso filtering a list is easy, just type in a few characters, doesn't matter what order and the app will give you what you need. Scrolling a huge collations list is not what we, developers, like. We did put there some small but often use features like: Small but useful things may make work more pleasant. Focus on the current project and stop worrying about reopening tables and queries the next day. You can easily switch between projects, and the app will remember and restore all your tabs for each workspace. Con Cannot view function Con Trigger edition Until version 3.5.8 you can not edit triggers, only view (since 3.5.6). Ad Cons Con Never-ending function errors Like, 'Communications link failure', 'Connection refused' (Community Edition 6.2.1). We are developers, we know how other solutions do not meet our needs so we decided to make a fast and stable app with features that make our work better. Sqlectron supports PostgreSQL, MySQL (and MariaDB), MSSQL Server, SQLite, and Cassandra. SQL Client is a fast app created to be developer-friendly.
