IP range polling

The Administration Server polls the specified IP ranges using ICMP packets or the NBNS protocol and compiles a complete set of data on devices within those IP ranges. By default, this type of polling is disabled.

For all Linux-based hosts within a Microsoft Active Directory or Samba domain controller, specify the netbios name and workgroup parameters in the /etc/samba/smb.conf file. Otherwise, polling results may contain duplicate hosts.

Before you start network polling, make sure that the SMB protocol is enabled. Otherwise, Kaspersky Security Center cannot discover devices in the polled network. To enable the SMB protocol, follow the instructions for your operating system.

Viewing and modifying the settings for IP range polling

To view and modify the settings for polling IP range groups:

In the console tree, in the Device discovery folder, select the IP ranges subfolder.
You can proceed from the Unassigned devices folder to the Device discovery folder by clicking Poll now.
If you want, in the IP ranges subfolder click Add subnet to add an IP range for polling, and then click OK.
Click Configure polling.
The IP ranges properties window opens. If you want, you can modify the settings of IP range polling:
- Enable IP range polling
  This option is not selected by default. It is not recommended to use this type of polling if you use Windows network polling and/or Active Directory polling.
- Set polling schedule
  The default period is 420 minutes. The data received at the next polling completely replaces the old data.
  
  The following polling schedule options are available:
  - Every N days
    The polling runs regularly, with the specified interval in days, starting from the specified date and time.
    
    By default, the polling runs every day, starting from the current system date and time.
  - Every N minutes
    The polling runs regularly, with the specified interval in minutes, starting from the specified time.
    
    By default, the polling runs every five minutes, starting from the current system time.
  - By days of week
    The polling runs regularly, on the specified days of week, and at the specified time.
    
    By default, the polling runs every Friday at 6:00:00 PM.
  - Every month on specified days of selected weeks
    The polling runs regularly, on the specified days of each month, and at the specified time.
    
    By default, no days of month are selected; the default start time is 6:00:00 PM.
  - Run missed tasks
    If the Administration Server is switched off or unavailable during the time for which the poll is scheduled, the Administration Server can either start the poll immediately after it is switched on, or wait for the next time for which the poll scheduled.
    
    If this option is enabled, the Administration Server starts polling immediately after it is switched on.
    
    If this option is disabled, the Administration Server waits for the next time for which the polling is scheduled.
    
    By default, this option is enabled.

If you want to perform the poll immediately, click Poll now. This button is only available if you selected Enable IP range polling.

On the virtual Administration Server, you can view and edit the settings for IP range polling in the distribution point properties window, in the Device discovery section. Client devices discovered during the poll of IP ranges are displayed in the Domains folder of the virtual Administration Server.
