Getting started with remote with the thin client 

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. In the Remote Development wizard, click Connect via SSH.

   

   note

   You can also click Connect to Remote Host with a Link and enter a link that you previously generated to connect either to a Code With Me session or to a remote server.

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).

   • User name: 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 CLion, 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. CLion 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 CLion 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. For more information, refer to 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 CLion 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 CLion is located in the following folder on the remote server: ~/.cache/JetBrains/RemoteDev/dist. However, you can change it and install CLion into a custom location with the following steps:

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

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

Add the path to your project on the remote host.

Click Download and Start IDE.

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.

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 .

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 Instance 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.

Connect to remote IDE

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

2. Ensure you have an SSH connection to the remote machine and the CLion IDE on it.

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

   See 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 receive in the terminal 3 links:

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

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

     tip

     Check "ssh -L" for detailed information.

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

     When opening 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 Gateway app 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.

     When opening in your local browser, it launches the local Gateway app directly without a welcome page.

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

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

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

   CLion downloads JetBrains Client of the required version and opens the remote project in it.

Connect via Space

1. Launch JetBrains Gateway.

2. On the JetBrains Gateway starting page, select JetBrains Space and click Connect to Space.

3. Log in to JetBrains Space with your credentials.

   

4. Click Continue in Browser and make sure you are connected.

   

   Click Allow to get back to JetBrains Gateway.

5. In JetBrains Gateway, click Browse Dev Environments.

   

6. In Space, configure the dev environment you want to use.

7. Find the project you want to open remotely and click Open in IDE.

8. In the dialog that opens, in the Select IDE drop-down, select CLion with Gateway, configure other options if you need, and click Create.

9. On the page that opens, click Open JetBrains Gateway.

   

   JetBrains Gateway launches, downloads all the necessary backend components, and opens JetBrains Client with your project where you can work further.

Install a plugin via the command line

If you manually configure CLion on the remote server, use the following steps to add plugins:

1. From the JetBrains Marketplace page, find a page of the required plugin, select the Versions tab, and click any version to copy pluginId (short name such as org.rust.lang) of the plugin you want to install.

2. Open the remote server go to the CLion instance where your project resides, and for which you want to download and install a third-party plugin.

   By default, the downloaded CLion instances are located in the following directory:

   ~/.cache/JetBrains/RemoteDev/dist

3. Add the following command:

   bin/remote-dev-server.sh installPlugins PROJECT_PATH pluginId

   (where PROJECT_PATH is a path to your remote project and pluginId is an ID you got from the JetBrains Marketplace page.)

   After the installation, unpack the downloaded plugin's archive.

   By default, the installed plugin is placed into the following folder on the backend:

   ~/.cache/JetBrains/RemoteDev-IU/PROJECT_PATH/plugins/

4. Continue with launching JetBrains Gateway and opening the remote project with the remotely installed plugin.

Install a plugin via UI

If you use JetBrains Gateway to download CLion to a remote server, use the following steps to install plugins.

1. Open a remote project in JetBrains Client.

2. Press Ctrl+Alt+S to open the IDE settings and select Plugins On Host.

3. Download the needed plugin the same way as you would in a regular CLion project.

   For more information on regular plugin installation, refer to Plugins.

4. After you download and enable the plugin, click OK to save the changes.

   The plugin is installed remotely. However, keep in mind that the plugin is installed per project.

Add an SDK to the opened project

When you first open a project, CLion displays a notification suggesting to add the project SDK.

1. Open the remote session.

2. From the main menu, select File | Project Structure.

3. In the Project Structure dialog, select Project, and from the available options, configure the project's SDK.

4. Click OK to save the changes. CLion downloads the configured SDK to the remote server. The next time you open your project, the downloaded SDK will be used automatically in the remote session.

Add VM options

You can adjust VM options for the remote project, especially if you want to increase the -Xmx memory size when working with a larger project. You need to perform those actions and save your changes on the remote server.

1. From the main menu, select Help | Edit Custom VM Options (On Host).

2. Edit the clion64.vmoptions file.

   For example, change the -Xmx2048 option to -Xmx3072.

   For more detailed information on VM options, refer to Advanced configuration.

3. Restart your IDE on the remote server to see the changes.

Close the Remote Development session

• Click to close the remote session window.

  You are returned to the JetBrains Gateway welcome screen where you can use the Recent SSH projects page to reconnect to your remote session or stop the running instance.

  note

  When you close the project locally, it doesn't get automatically closed on the remote host.

Create multiple connections

You can create multiple connections to the same remote host and the same version of the IDE. You can also have connections with different IDE versions and remote hosts.

1. Connect and open a remote session.

2. Since JetBrains Gateway is constantly active once you have connected to the remote server, you can click its icon to open the JetBrains Gateway welcome screen and configure other connections.

   If you connect to the same IDE version, then JetBrains Client will be opened as an instance of the same process. If you connect to a different remote host or IDE version, a different remote session will be launched.

   note

   You cannot connect to the same server from different computers. For example, if you share a remote server with your team and want to work on the same project, either wait until the server is free or request the Code With Me link from the connected party to join the remote session.
