Configuring Ports

You can optionally configure the various ports that TORQUE uses for communication. Most ports can be configured multiple ways. The ports you can configure are:

pbs_server listening port
pbs_mom listening port
port pbs_server uses to communicate to the pbs_mom
port pbs_mom uses to communicate to the pbs_server
port client commands use to communicate to the pbs_server
port trqauthd uses to communicate to the pbs_server

If you are running pbspro on the same system, be aware that it uses the same environment variables and /etc/services entries.

Configuring the pbs_server Listening Port

To configure the port the pbs_server listens on, follow any of these steps:

Set an environment variable called PBS_BATCH_SERVICE_PORT to the port desired.
Edit the /etc/services file and set pbs port_num/tcp.
Start pbs_server with the -p option.

$ pbs_server -p port_num

Edit the $PBS_HOME/server_name file and change server_name to server_name:<port_num>
Start pbs_server with the -H option.

$ pbs_server -H server_name:port_num

Configuring the pbs_mom Listening Port

To configure the port the pbs_mom listens on, follow any of these steps:

Set an environment variable called PBS_MOM_SERVICE_PORT to the port desired.
Edit the /etc/services file and set pbs_mom port_num/tcp.
Start pbs_mom with the -M option.

$ pbs_mom -M port_num

Edit the nodes file entry for that list: add mom_service_port=port_num.

Configuring the Port pbs_server Uses to Communicate with pbs_mom

To configure the port the pbs_server uses to communicate with pbs_mom, follow any of these steps:

Set an environment variable called PBS_MOM_SERVICE_PORT to the port desired.
Edit the /etc/services file and set pbs_mom port_num/tcp.
Start pbs_mom with the -M option.

$ pbs_server -M port_num

Configuring the Port pbs_mom Uses to Communicate with pbs_server

To configure the port the pbs_mom uses to communicate with pbs_server, follow any of these steps:

Set an environment variable called PBS_BATCH_SERVICE_PORT to the port desired.
Edit the /etc/services file and set pbs port_num/tcp.
Start pbs_mom with the -S option.

$ pbs_mom -p port_num

Edit the nodes file entry for that list: add mom_service_port=port_num.

Configuring the Port Client Commands Use to Communicate with pbs_server

To configure the port client commands use to communicate with pbs_server, follow any of these steps:

Edit the /etc/services file and set pbs port_num/tcp.

Edit the $PBS_HOME/server_name file and change server_name to server_name:<port_num>

Configuring the Port trqauthd Uses to Communicate with pbs_server

To configure the port trqauthd uses to communicate with pbs_server, follow any of these steps:

Edit the $PBS_HOME/server_name file and change server_name to server_name:<port_num>
