Description

gds_ctl.py can be used to start or stop GDS if gds.conf is configured.

Parameter Description

start
Enable the GDS configured in gds.conf.
stop
Stop the running instance started by the configuration file in the GDS that can be disabled by the current users.
stop all
Stop all the running instances in the GDS that can be disabled by the current users.
stop [ ip: ] port
