4 Modifying the configuration and it's integrity check

Errors occured attempting to create or configure the dpi (by configuing the file: /etc/dpi/fastdpi.conf) may cause the dpi fails to start, so it is highly recommended to back up the original configuration file (/etc/dpi/fastdpi.conf), edit this backup file, check it using diagnostic command, and only after that to replace the original file with newly created one and to restart dpi.

Example of recommended actions:

#create backup file cp /etc/dpi/fastdpi.conf /etc/dpi/fastdpi.conf.new #edit backup file vi /etc/dpi/fastdpi.conf.new #integrity test fastdpi -p -c /etc/dpi/fastdpi.conf.new #Result check configuration : SUCCESS means that configuration is valid #replase the original configuration file by newly created one cp /etc/dpi/fastdpi.conf.new /etc/dpi/fastdpi.conf #restart dpi service fastdpi restart
