Enabling remote access to Talend Remote Engine using SSH (optional)

By default, only the localhost machine has SSH access to Talend Remote Engine. To enable remote access from other machines, edit the configuration file and set secure access credentials.

Procedure

  1. Open the <RemoteEngineInstallationDirectory>/etc/org.apache.karaf.shell.cfg file.
    By default, the sshHost value is set to localhost.
  2. Change the sshPort value to 0.0.0.0, then save your changes.

Results

You can now connect to Talend Remote Engine from other machines using SSH.

Changing the auto-generated default SSH password

By default, an SSH password is automatically created for the default Remote Engine user during installation. You can manually change this password as needed.

About this task

Even if the installer generates a strong SSH password, change it in specific situations, such as connecting to the Karaf console or extracting a Karaf dump through RE-helper. For further information about this password generation with installer, see Installing the Remote Engine automatically.

If you manually installed Talend Remote Engine using the archive instead of the installer, tadmin is used as the default SSH password. For security reason, you must change it.

Procedure

  1. Open the <RemoteEngineInstallationDirectory>/etc/users.properties file in a text editor.
  2. Locate the line for the default user. The default format is: 
    <default-user> = <password>,<roles-or-groups>
    For example: 
    tadmin = tadmin,_g_:admingroup
  3. Replace <password> with a new strong password.
  4. Save the file.
    If the engine is running when you make this change, the password is automatically encrypted after saving. Otherwise, the encryption occurs when the engine starts. For example: 
    tadmin = {CRYPT}6BA00DCABFDDDE0F9A96B4CA68C13DBEE23597E5925656680C501889C4A554604201B37069754392{CRYPT},_g_:admingroup

Results

The default password is updated. Use it for tasks like connecting to the Karaf console or extracting Karaf dumps.
