named-xfer − pull BIND/Hesiod zones from another server

Syntax

/usr/etc/named-xfer −z zone_to_transfer −f db_file −s serial_no [ −d debug_level ] [ −l debug_log_file ] [ −t trace_file ] [ −p port ] [ −n ] [ −a auth_type.auth_ver ] servers... 

Description

The named transfer daemon, /usr/etc/named-xfer, is a server that is usually run by the named daemon, /usr/etc/named, but it can also be run manually with the given arguments.  The named transfer daemon runs on a BIND/Hesiod secondary server and pulls BIND/Hesiod zones from a primary server. This daemon is not run by default, nor can it be started up from inetd(8c).

Options

−z zone_to_transferThis option is required to pull a zone.  The zone_to_transfer argument specifies the name of the BIND/Hesiod zone that the named-xfer daemon will transfer, for example, dec.com.

−f db_fileThis option is  required to pull a zone.  The db_file argument specifies the name of the file into which the pulled zone information is placed. 

−s serial_noThis option is required to pull a zone.  The serial_no argument should be set to the current serial number of the SOA record for the zone zone_to_transfer.  If serial_no is set to 0, the zone is always pulled. 

−d debug_levelThe debug_level argument sets the debug level and determines the amount of debug information to be displayed. 

−l debug_log_fileThe debug_log_file argument specifies the file that will contain any debug messages from the zone pull. 

−t trace_fileThe trace_file argument specifies the file that will contain a trace from the zone pull. 

−p portThe port argument specifies the port that will be used instead of the default nameserver port listed in /etc/services.

−nThis option must be used when the named daemon is running in the network safe mode.  It indicates that the zone pull must be authenticated.

−a  auth_type.auth_ver
This option must be used if the named daemon is running in the network safe mode.  The auth_type argument indicates what type of authentication to use and the auth_ver argument indicates what version of the authentication type to use.  Currently, the auth_type must be "kerberos" and the auth_ver must be "one". 

servers...The servers argument is a list of Internet addresses from which to pull a zone.  If the first host cannot be ddreached, the named transfer daemon will try to pull the zone from the next host listed.
