Introduction
     trqauthd is a new daemon starting in TORQUE 4.0. It replaces pbs_iff which is used by 
     TORQUE client utilities to authorize user connections to pbs_server. Unlike pbs_iff 
     which is executed by the TORQUE client utilities each time the utility is run, trqauthd
     is started once and remains resident. TORQUE client utilities then communicate with 
     trqauthd on port 15005 on the loopback interface. Unlike pbs_iff trqauthd is multi-threaded
     and is able to successfully handle a greater volume of simultaneous requests than pbs_iff.

Running trqauthd

     trqauthd MUST be run as root. It must be running on any host where TORQUE client commands 
     will execute.

     By default trqauthd is installed to /usr/local/bin.

     trqauthd can be invoked directly from the command line or by the use of init.d scripts 
     which are located in the contrib/init.d directory of the TORQUE source.

     There are three init.d scripts for trqauthd in the contrib/init.d directory of the 
     TORQUE source tree. 

     debian.trqauthd
     Used for the apt based systems (debian, ubuntu are the most common variations of this)

     suse.trqauthd
     Used for the rpm based systems. (redhat, suse, scientific, centos, fedora, are some 
     common examples)

     trqauthd
     An example for other packages managers. (anything that doesn't use rpm or apt)

     Inside each of the scripts are the variable PBS_DAEMON and PBS_HOME. These two variables
     should be updated to match your torque installation. PBS_DAEMON needs to point to the
     location of trqauthd. PBS_HOME needs to match your TORQUE installation. For more information
     about PBS_HOME please see the TORQUE documentation at www.adaptivecomputing.com.

     Choose the script that matches your dist system and copy it to /etc/init.d. If needed, 
     renamed it to trqauthd

     To start the daemon type:
          /etc/init.d/trqauthd start

     To stop the daemon type:
          /etc/init.d/trqauthd stop

     You can also use the following:
          service trqauthd start/stop
