Connect and work with JetBrains Gateway

Launch JetBrains Gateway and connect to a remote server

1. Download and install the JetBrains Gateway app.

   Alternatively, you can access JetBrains Gateway from the welcome screen of your IDE through the Remote Development option.

2. Сlick New Connection under the SSH connection provider.

   

3. On the next page of the wizard, specify the SSH configuration through which you want to connect to a remote server.

   

   Alternatively, click to open the SSH Configurations dialog and configure the SSH settings.

   In the SSH Configurations dialog, add the following information:

   

   • Host: specify the address of your remote server.

   • Port: specify the SSH port, which defaults to 22.

   • Local port: specify the outgoing port.

     For example, TCP 10.101.0.1:50705->13.49.137.87:22 (ESTABLISHED).

   • Username: specify the name of a user that will be used to connect to the remote server.

   • Authentication type: select one of the following authentication methods:

     • Password: to access the host with a password. To save the password in RustRover, select the Save password checkbox.

     • Key pair (OpenSSH or PuTTY): to use SSH authentication with a key pair. To apply this authentication method, you must have a private key on the client machine and a public key on the remote server. RustRover supports private keys that are generated with the OpenSSH utility.

       Specify the path to the file where your private key is stored and type the passphrase (if any) in the corresponding fields. To have RustRover remember the passphrase, select the Save passphrase checkbox.

     • Parse config file ~/.ssh/config: select this option if you want JetBrains Gateway to use the .ssh/config file.

   • Test Connection: click this button to see whether the connection is established.

   • Connection Parameters: use this section to configure additional parameters for the connection.

   • HTTP/SOCKS Proxy: use this section to configure proxy settings.

   Click OK to save the changes and return to the Welcome to JetBrains Gateway dialog.

   Click Check Connection and Continue to check whether the connection is established.

4. On the next page, specify the RustRover version to download to the remote server. JetBrains Gateway displays a list of the IDEs versions that are available for downloading and the already installed ones.

   You can also use "Other options" for setting the alternative sources of IDE installers.

   The version of JetBrains Client downloaded to your local machine always matches the remote IDE version.

By default, the downloaded RustRover is located in the following folder on the remote server: ~/.cache/JetBrains/RemoteDev/dist. However, you can change it and install RustRover into a custom location with the following steps:

1. Click Other options and select the Customize install path option.

2. In the Install path field add the needed location for the installation.

Add the path to your project on the remote host.

Click Upload IDE and Connect.

JetBrains Gateway downloads the IDE, and opens your remote project in JetBrains Client. The connection is shown in the JetBrains Gateway window, from which you can connect to other IDEs or disable the connection. This window is hidden to tray by default.

Override -Xmx VM options

1. Launch JetBrains Gateway.

2. Follow the steps of the wizard. Click Check Connection and Continue.

3. On the page that opens, under the IDE version field, click Installation options.

4. From the drop-down list, select the Customize heap size.

5. In the Maximum heap size field, override the default heap size as needed.

   Note that this field can only contain numeric values and cannot exceed the INT_MAX value.

6. After you've done with your configurations, click Download IDE and Connect to start your project.

Open recent projects

1. In the JetBrains Gateway wizard, select SSH from the options on the left.

2. In the search field, enter the name of your project to quickly navigate to it.

   If you need to quickly access the terminal, click .

Change the backend version

• In the JetBrains Gateway wizard, click next to the name of the recent project and choose the version of the backend with which you want to open your project.

  

  If you can't locate the necessary version in the list, click Select Different IDE and choose the desired IDE version in the IDE version field.

  

Stop the running instance

1. In the JetBrains Gateway wizard, select SSH from the options on the left.

2. When your remote session is active, the Running indicator is displayed next to the project.

   Click next to the project and select Stop IDE Backend to stop the remote session for that project.

   You can also select Remove from Recent Projects to remove the project listed on the page altogether.

Uninstall the backend IDE version

1. In the JetBrains Gateway wizard, click against the name of the remote server and select Manage IDE Backends to open the list of installed IDE versions.

   

2. In the window that opens, click next to the backend IDE version you need to uninstall and click Yes to confirm the action.

1. Start a backend project in the remote IDE.

2. Select one of the connection links generated by the backend.

3. Open the link on your local machine.

Connect to a remote IDE

1. Ensure you have downloaded and installed JetBrains Gateway or you have an IDE with the JetBrains Gateway plugin on your local machine.

2. Ensure you have connected to the remote machine with RustRover via SSH.

3. In the remote server's terminal, run the following command:

   remote-dev-server.sh run /path_to_project/ --ssh-link-host host_server_address --ssh-link-user remote_side_user --ssh-link-port ssh_connection_port

   Check the following example:

   ~/ideaIU-213.3469/bin/remote-dev-server.sh run ~/spring-boot-example/ --ssh-link-host ec2-11-50-136-85.eu-north-1.compute.amazonaws.com --ssh-link-user ubuntu

   If you don't pass the parameters, the script will use the default ones: 22 for port, system user's username, and host from the hostname command.

4. If the project starts successfully, as an output, you should receive the following 3 links in the terminal:

   • Join link: tcp://127.0.0.1:5990...[ ]: contains the local address and port where the remote IDE is listening now.

     Example:

     tcp://127.0.0.1:5991#jt=71e779a1-070e-4fd3-a4e6-83c1f8cb65a5&p=IU&fp=A42F6041C2878D7A22339ECABF4A9C294F643BG05E91E3DFC06035E03DB71BF8&cb=222.4167.29&jb=17.0.4b469.53

     To use it, ensure the remote machine should be accessible by this local address. For example, for inside-Docker IDE with forwarded/open ports.

   • Http link: https://code-with-me.jetbrains.com/remoteDev...[ ]: contains information about your host-port-user, the IDE and its version.

     Example:

     https://code-with-me.jetbrains.com/remoteDev#idePath=%2Fhome%2Fubuntu%2F.cache%2FJetBrains%2FRemoteDev%2Fdist%2F3e4cd27bfbb95_ideaIU-2022.2.2&projectPath=%2Fhome%2Fubuntu%2Fdevelopment%2Fspring-petclinic&host=ec2-xx-xx-xxx-xx.eu-north-1.compute.amazonaws.com&port=22&user=ubuntu&type=ssh&deploy=false

     When opened in your local browser, it displays a welcome page and tries to call the local Gateway application with pre-filled connection settings values.

     If no JetBrains Gateway application is found on the local machine, you'll be able to download it from the welcome page.

   • Gateway link: jetbrains-gateway://connect#idePath... [ ]: also contains information about your host-port-user, IDE and its version.

     Example:

     jetbrains-gateway://connect#idePath=%2Fhome%2Fubuntu%2F.cache%2FJetBrains%2FRemoteDev%2Fdist%2F3e4cd27bfbb95_ideaIU-2022.2.2&projectPath=%2Fhome%2Fubuntu%2Fdevelopment%2Fspring-petclinic&host=ec2-xx-xx-xxx-xx.eu-north-1.compute.amazonaws.com&port=22&user=ubuntu&type=ssh&deploy=false

     When opened in your local browser, it launches the local JetBrains Gateway application directly without a welcome page.

5. Copy the generated link and paste it into your local browser allowing it to Open JetBrains Gateway.

6. All these links can be also opened in the already launched JetBrains Gateway.

   For this, on the JetBrains Gateway welcome screen, paste a link in the Connect to a Running IDE field, click Connect.

   RustRover downloads the required version of JetBrains Client and opens the remote project inside it.
