To execute fdpi_ctrl utility remotely one has to make the following actions:

To enable listening for the network control interface in DPI configuration file /etc/dpi/fastdpi.conf:

ctrl_dev=eth0

To open the access to the port configured by ctrl_port in firewall settings /etc/sysconfig/iptables and to limit an access to DPI host from the control server only:

-A INPUT -m state --state NEW -m tcp -s 192.168.0.2 -p tcp --dport 2900 -j ACCEPT

To copy fdpi_ctrl utility to the control server and start it with an argument -r host:port:

fdpi_ctrl load --service 6 --login test -r 192.168.0.1:2900

Please take care to update fdpi_ctrl on the control server on each DPI update.
