So technically DBeaver will connect to something like localhost:45678 (radnom port on localhost) instead of :5432 (default PostgreSQL server port).īut if you use URL instead of manual connection configuration then you connect to jdbc:postgresql:///postgresql. It then implicitly replaces port configured in the connection with this random port. SSH + URL-based connectionsīy defaul DBeaver opens random local port and forwards it to a target database port. when you want to use a particular local port. It is not usually required to change this configuration, but it can be useful e.g. This is when port forwarding becomes handy.īy default, it randomly chooses the local port and forwards it to the destination port set in Connection settings ⇒ Main Now you need to pass the port on which the database is listening to from that remote machine to your local machine. After the SSH connection to the remote machine is established, you now need to connect to the database on that machine. Port forwarding is used to expose some socket sitting on a remote port to your local port, allowing you to communicate with it. If the destination SSH machine is quite slow and the connection takes ages to complete, you can adjust the value of this parameter. Can be used to "ping" a remote machine to make sure that the SSH connection is still alive. Optional port forwarding configuration, see information at below.Jump servers are only available with Jsch implementation. You will need to specify 100.100.100.100 as a host in regular SSH configuration and 200.200.200.200 as a host in a gateway configuration to achieve such a "connection order": localhost → 200.200.200.200 → 100.100.100.100. You cannot access this IP directly from your machine because of your network settings or firewall, but you can access other machines with the IP address 200.200.200.200 through SSH and which is able to access the desired remote machine. Imagine you have the following situation: your database is located on remote machine with IP address 100.100.100.100 and which is accessible through SSH. Gateway has the same configuration as for regular SSH tunnel: Just like SSH configuration, you have to enable it first. Gateway host, sometimes known as jump host, is used in situations when you cannot access a particular machine directly from your local machine, but it is possible to use a gateway server. After connecting to remote machine, all commands you execute are executed on that remote machine, so by having the host set to localhost you are opening a connection to the database on this remote machine, not on your local machine, and just redirect I/O to the latter. ![]() ![]() SSH establishes a connection between two machines, authenticating each side to the other, and passing commands and output back and forth. It is often required to set the hostname to localhost in Connection settings ⇒ Main. After that, configure it for your needs, then click on Test tunnel configuration to test whether all parameters are valid or not. In order to use SSH, you have to enable it first. SSH can either be configured individually for each connection in Connection settings ⇒ SSH 1 or as a which can be selected from the drop-down menu 2 on the same page mentioned earlier: Note that you have to run the agent first before connecting to the database in DBeaver. The SSH or Secure Shell is a network communication protocol that allows two computers to communicate and encrypts the shared data.ĭBeaver supports the following SSH authentication methods:Īvailable agent authentication implementations: Sometimes the database cannot be accessed directly, in such cases you can use the SSH tunnel. Importing CA certificates from your local Java into DBeaver.Connecting to Oracle Database using JDBC OCI driver.Installing extensions - Themes, version control, etc.
