Hardening in Vcenter – Inactivity Timeout


If you open a vcenter application and forget to close the application, unauthorized person can able to change or view the configuration in Vcenter. Hence it requires session timeout if the Vcenter is not in use.


To configure the session time out in Vcenter, you need to locate the file VpxClient.exe.config. This file is available in the following path

32bit – %PROGRAMFILES%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher

64bit – %PROGRAMFILES(x86)%\VMware\Infrastructure\Virtual Infrastructure  Client\Launcher

Edit the file using text editor like Notepad, Wordpad etc…

Insert and type the text in between as given below.


“<!– ignore sertificate validation problems:

    <ignorecert />”





Save the file and close. Here X represent the time in minute.

The example screenshot of the inactivity timeout given below.



Also type the -inactivity timeout X,  by right click the VSphere client icon available in Desktop and select the shortcut option. Go to target, you will see the path of the VPXClient . At the end of the line type the –inactivity timeout X. please see the below diagram.
