Configuring trqauthd for client commands
trqauthd is a daemon used by TORQUE client utilities to authorize user connections to pbs_server. Once started, it remains resident. TORQUE client utilities then communicate with trqauthd on port 15005 on the loopback interface. It is multi-threaded and can handle large volumes of simultaneous requests.
Running trqauthd
trqauthd must be run as root. It must also 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:
| Script | Description |
|---|---|
| debian.trqauthd | Used for apt-based systems (debian, ubuntu are the most common variations of this) |
| suse.trqauthd | Used for suse-based systems |
| trqauthd | An example for other package managers (Redhat, Scientific, CentOS, and Fedora are some common examples) |
You should edit these scripts to be sure they will work for your site.
Inside each of the scripts are the variables 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.
Choose the script that matches your dist system and copy it to /etc/init.d. If needed, rename it to trqauthd.
To start the daemon
/etc/init.d/trqauthd start
To stop the daemon
/etc/init.d/trqauthd stop
OR
service trqauthd start/stop
If you receive an error that says "Could not open socket in trq_simple_connect. error 97" and you use a CentOS, RedHat, or Scientific Linux 6+ operating system, check your /etc/hosts file for multiple entries of a single host name pointing to the same IP address. Delete the duplicate(s), save the file, and launch trqauthd again.
