Locale

The locale used for the application events sent to Kaspersky Security Center.

The locale of the graphical interface and the application command line depends on the value of the LANG environment variable. If the locale that is not supported by Kaspersky Endpoint Security is specified as the value of the LANG environment variable, the graphical interface and the command line are displayed in English.

The locale in the format specified by RFC 3066.

If the Locale setting is not specified, the operating system locale is used. If the application fails to determine the operating system localization language or the operating system localization is not supported, the default value will be used – en_US.utf8.

UseFanotify

Indicates use of fanotify notifications.

True/Yes – The operating system supports fanotify notifications.

False/No – The operating system does not support fanotify notifications.

Filled out automatically during the initial setup of the application.

MachineId

The user's unique device ID.

Filled out automatically during the initial setup of the application.

CoreDumps

Enables the creation of a dump file when application failure occurs.

True/Yes (default value) – Create a dump file when the application fails.

False/No – Do not create a dump file when the application fails.

SocketPath

Path to a socket for a remote connection to, say, a graphical interface and the kesl-control utility.

Default value: /var/run/bl4control.

StartupTraces

Enables generation of trace files at application startup.

MaxInotifyInstances

Limit on the number of subscriptions to changes in files and directories for a single user.

Default value: 2048.

ExecEnvMax

The number of environment variables that the application captures from the command call.

Default value: 50.

AdditionalDNSLookup

Indicates use of a public DNS.

If there are errors accessing servers through the system DNS, the application uses a public DNS. This is needed for updating application databases and maintaining device security. The application will use the following public DNSes in this order:

  • Google Public DNS (8.8.8.8).
  • Cloudflare DNS (1.1.1.1).
  • Alibaba Cloud DNS (223.6.6.6).
  • Quad9 DNS (9.9.9.9).
  • CleanBrowsing (185.228.168.168).

The application's requests may contain domain addresses and the user's external IP address, since the application establishes a TCP/UDP connection with the DNS server. This information is necessary, for example, to check the certificate of a web resource when interacting via HTTPS. If the application is using a public DNS server, data processing rules are governed by the Privacy Policy of the corresponding service. If you need to block the application from using a public DNS server, contact Technical Support for a private patch.

True/Yes – Use a public DNS to access Kaspersky servers.

False/No (default value) – Do not use a public DNS to access Kaspersky servers.

The [Network] section contains the following settings:

WtpFwMark

A mark in the iptables rules for forwarding traffic to the application for processing by Web Threat Protection tasks. You may need to change this mark if a device with the application runs other software that uses the ninth bit of the TCP packet mask, and a conflict occurs.

A decimal value or hexadecimal number with the prefix 0x.

Default value: 0x100.

NtpFwMark

A mark in the iptables rules for forwarding traffic to the application for processing by Network Threat Protection tasks.

You may need to change this mark if a device with the application runs other software that uses the ninth bit of the TCP packet mask, and a conflict occurs.

A decimal value or hexadecimal number with the prefix 0x.

Default value: 0x200.

BypassFwMark

A mark used to indicate packets created or scanned by the application, so that the application does not scan them again.

A decimal value or hexadecimal number with the prefix 0x.

Default value: 0x400.

BypassNFlogMark

A mark used to indicate packages created or scanned by the application to prevent them from being logged by the iptable utility.

A decimal value or hexadecimal number with the prefix 0x.

Default value: 0x800.

ProxyRouteTable

Number of the routing table.

Default value: 101.
