controls
Statement
Syntax
controls { [ inet ip_addr port ip_port allow { address_match_list; }; ] [ unix path_name perm number owner number group number; ] };
Definition and Usage
The
controls
statement declares control channels to be used by system administrators to affect the operation of the local name server. These control channels are used by thendc
utility to send commands to and retrieve non-DNS results from a name server.A
unix
control channel is a FIFO in the file system, and access to it is controlled by normal file system permissions. It is created bynamed
with the specified file mode bits (see thechmod
(1) manual page), user and group owner. Note that, unlikechmod
, the mode bits specified forperm
will normally have a leading 0 so the number is interpreted as octal. Also note that the user and group ownership specified asowner
andgroup
must be given as numbers, not names. It is recommended that the permissions be restricted to administrative personnel only, or else any user on the system might be able to manage the local name server.An
inet
control channel is a TCP/IP socket accessible to the Internet, created at the specified ip_port on the specified ip_addr. Modern telnet clients are capable of speaking directly to these sockets, and the control protocol is ARPAnet-style text. It is recommended that 127.0.0.1 be the only ip_addr used, and this only if you trust all non-privileged users on the local host to manage your name server.
