Why Am I Seeing the Message Indicating That the Port Is Used by a One-Click Password Reset Plug-in?

Symptom

When you attempt to run an application on an ECS, the system displays a message indicating that the required port is used by a one-click password reset plug-in.

Possible Causes

If an ECS works in AUTO mode, when its one-click password reset plug-in starts, the plug-in randomly use a port, which may be a service port.

The one-click password reset plug-in has been upgraded to work in PIPE mode by default.

  • Newly created ECSs run in PIPE mode by default, and their one-click password reset plug-ins will not use service ports.
  • Existing ECSs still work in AUTO mode, in which the plug-ins randomly select idle ports with the smallest port numbers ranging from 31000 to 32999.

Method 1 (Recommended): Modifying the wrapper Files of the One-Click Password Reset Plug-in for the PIPE Mode

In the wrapper files, change AUTO (SOCKET) to PIPE. After the change, the plug-in will not use service ports.

  1. Open CloudResetPwdAgent configuration files.
    • Linux

      /CloudrResetPwdAgent/conf/wrapper.conf and /CloudResetPwdUpdateAgent/conf/wrapper.conf

    • Windows

      C:\CloudResetPwdUpdateAgent\conf\wrapper.conf and C:\CloudResetPwdUpdateAgent\conf\wrapper.conf

  2. Add the following data to the end of the files:

    wrapper.backend.type=PIPE

  3. Restart CloudResetPwdUpdateAgent.
    • Linux

      /CloudResetPwdUpdateAgent/bin/cloudResetPwdUpdateAgent.script restart

    • Windows
      1. Press Win+R to start the Run text box.
      2. Enter services.msc and click OK.

      3. Right-click cloud reset password update agent and choose Restart from the shortcut menu.

Method 2: Modifying the Configuration to Change the Port Range

Modify the CloudResetPwdAgent configuration to change the default port range (31000–32999) for the password reset plug-in so that the service port is out of the port range.

For example, to change the port range for the password reset plug-in to 40000–42000, perform the following operations:

  1. Open CloudResetPwdAgent configuration files.
    • Linux

      /CloudrResetPwdAgent/conf/wrapper.conf and /CloudResetPwdUpdateAgent/conf/wrapper.conf

    • Windows

      C:\CloudResetPwdUpdateAgent\conf\wrapper.conf and C:\CloudResetPwdUpdateAgent\conf\wrapper.conf

  2. Add the following data to the configuration files:

    wrapper.port.min=40000

    wrapper.port.max=41000

    wrapper.jvm.port.min=41001

    wrapper.jvm.port.max=42000

  3. Restart CloudResetPwdUpdateAgent.
    • Linux

      /CloudResetPwdUpdateAgent/bin/cloudResetPwdUpdateAgent.script restart

    • Windows
      1. Press Win+R to start the Run text box.
      2. Enter services.msc and click OK.
