Syntax

named [PARAMETER ...]

Parameters

-4

Use IPv4 only even if the host machine is capable of IPv6. -4 and -6 are mutually exclusive.

-6

Use IPv6 only even if the host machine is capable of IPv4. -4 and -6 are mutually exclusive.

-t DIRECTORY

chroot() to DIRECTORY after processing the command line arguments, but before reading the configuration file.

WARNING:

This option should be used in conjunction with the -u option, as chrooting a process running as root doesn't enhance security on most systems; the way chroot() is defined allows a process with root privileges to escape a chroot jail.

-u USER

setuid() to USER after completing privileged operations, such as creating sockets that listen on privileged ports.
