Service Management

Subscriber management is performed using the utility fdpi_ctrl.

We recommend using Named profiles, which will simplify service management.

Command Syntax

General command format:

fdpi_ctrl command --service service_id [IP_list] [LOGIN_list]

Command parameter breakdown:

Parameter Description, possible values, and format Note
command Values:
1. load — load data
2. del — delete. For --service, the service_id must be specified
3. list — show information for the specified IP_list or all information if the argument all is specified.
In the list and del commands, instead of an IP/LOGIN list, you can specify all, which applies the command to all.
service_id Numeric ID corresponding to a service from the list.
IP_list Values:
1. --file — file with IP list
2. --ip — single IP, format: 192.168.0.1
3. --ip_range — IP range (inclusive), format: 192.168.0.1-192.168.0.5
4. --cidr — IP with port, format: 192.168.0.0/30, 5.200.43.0/24~ (CIDR range with excluded boundary addresses)
The CIDR range can exclude boundary addresses (gateway and broadcast addresses under classless addressing) by adding the ~ symbol at the end of the CIDR definition, e.g., --cidr 5.200.43.0/24~.
LOGIN_list Values:
1. --file — file with login list
2. --login — single login, format: USER1, "FIRST_NAME LAST_NAME" (option to use login with escaped special characters)
"USER1" — example of using login in double quotes
'USER2' — example of using login in single quotes
A line starting with # is a comment.

List of Services

When enabling blocking services (4, 16, 49), only TCP traffic is blocked. To block UDP traffic as well, you need to enable the udp_block parameter.

Examples

  1. Enable service:
    fdpi_ctrl load --service 9 --ip 192.168.0.1
    # or
    fdpi_ctrl load --service 9 --login USER1
  2. Disable service:
    fdpi_ctrl del --service 9 --ip 192.168.0.1
  3. Get list with the connected service:
    fdpi_ctrl list all --service 9
  4. Get information for a specific IP:
    fdpi_ctrl list --service 9 --ip 192.168.0.1
  5. When specifying the IP list, you can simultaneously specify several options: --file, --ip, --ip_range, --cidr:
    fdpi_ctrl list --service 9 --ip 192.168.0.1 --ip 192.168.0.2 --file fip_1.txt --ip_range 192.168.0.3-192.168.0.6 --login USER1

    The operation will apply to all specified elements where no error occurred.
    :!: If an error occurs, changes are not rolled back!

  6. Enabling services with named profiles:
    fdpi_ctrl load --service 4 --profile.name blocked --login Test

TCP and UDP Protocol Blocking Configuration

The parameter udp_block is responsible for blocking the UDP protocol. If the udp_block parameter is present in the DPI configuration file /etc/dpi/fastdpi.conf, both TCP and UDP will be blocked; if absent, only TCP will be blocked.

To start blocking UDP protocols (e.g., QUIC), add the udp_block parameter with a value of 2 or 3 (start blocking after two or three passed packets). These values are set because sometimes a large number of individual packets pass, which are not accounted for in the traffic but can put a heavy load on DPI.

udp_block=3

Adding the parameter does not require a DPI restart; a simple reload is sufficient:

service fastdpi reload
