Configuring file listener security for Talend JobServer

Last updated: 9/10/2026
Configure file listener security in Talend JobServer to prevent triggers in Talend Administration Center from accessing sensitive system directories.

About this task

In Talend Administration Center, you can set triggers that "listen" on events such as creation or deletion of files in specific folders. The file listener security prevents triggers from monitoring the specified folders.

By default, the following paths for system data are blocked for security reasons:

  • /etc
  • /proc
  • /dev
  • /root
  • /lib
  • /boot
  • /sys
  • /var

If a trigger is configured in Talend Administration Center to monitor any path starting with a blocked path, Talend JobServer rejects the corresponding listener creation request.

Procedure

  1. Open the <jobserver-installation>/conf/TalendJobServer.properties file.
  2. Locate the FILE_LISTENER_BLOCKED_PATHS property.

    This property defines all absolute paths that Talend JobServer blocks from file listener access. Paths are separated by commas.

    # Absolute paths blocked for usage with file listeners for security reasons.
# Remove a path if you really want to listen to a file located at a path starting with a string specified here.
# Replace with "/" if you want to disable all file listeners
org.talend.remote.jobserver.commons.config.JobServerConfiguration.FILE_LISTENER_BLOCKED_PATHS=/etc,/proc,/dev,/root,/lib,/boot,/sys,/var
    To block triggers from monitoring any folder, replace the entire property value with a single forward slash, for example, 
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.FILE_LISTENER_BLOCKED_PATHS=/
    This configuration effectively deactivates all file triggers.
  3. Save the properties file.
  4. Restart Talend JobServer to apply the changes.

Results

After the file listener security is configured, Talend Administration Center can create file listeners only for paths that are not blocked on the Talend JobServer.
