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
