Access to public DNS servers

If access to Kaspersky servers by using the system DNS is not possible, Kaspersky Security Center Linux can use the following public DNS servers, in the following order:

1. Google Public DNS (8.8.8.8)
2. Cloudflare DNS (1.1.1.1)
3. Alibaba Cloud DNS (223.6.6.6)
4. Quad9 DNS (9.9.9.9)
5. CleanBrowsing (185.228.168.168)

Requests to these DNS servers may contain domain addresses and the public IP address of the Administration Server, because the application establishes a TCP/UDP connection to the DNS server. If Kaspersky Security Center Linux is using a public DNS server, data processing is governed by the privacy policy of the relevant service.

To configure the use of public DNS by using the klscflag utility:

1. Run the command line, and then change your current directory to the directory with the klscflag utility. The klscflag utility is located in the directory where the Administration Server is installed. The default installation path is /opt/kaspersky/ksc64/sbin.
2. To disable the use of public DNS, run the following command under the root account:

   klscflag -fset -pv ".core/.independent" -s Transport -n ForceUseSystemDNS -t d -v 1

3. To enable the use of public DNS, run the following command under the root account:

   klscflag -fset -pv ".core/.independent" -s Transport -n ForceUseSystemDNS -t d -v 0
