When attempting to inventory a RedHat Enterprise Linux 5 Server with a non-root account, the following error occurs:

System.Exception: sudo: sorry, you must have a tty to run sudo

RedHat Enterprise Linux 5 Server has a new requiretty flag within the /etc/sudoers file.  To resolve this error, users will need to turn off the requiretty flag by completing the following steps:

  1. Edit the /etc/sudoers file. You will see a line like this:

    Defaults     requiretty
  2. Change the above so that it is commented out as follows:

    #Defaults     requiretty
  3. Save the changes to the /etc/sudoers file
