NAME
getzone - get dns zone from server DESCRIPTION
getzone transfers a user-specified dns zone from a zone server and displays it in csv1 format on the standard output. This program is here for compatibility with older setups that use getzone to get zone files; newer setups may wish to consider using the fetchzone tool to obtain csv2-compatible zone files. USAGE
getzone zone_name zone_server_IP [query_class] OPTIONS
zone_name Name of the dns zone to be transferred. zone_server_IP IP address of dns server query_class Optional argument which can change the query class from 1 (the default) to 255. This may be needed for some versions of Bind. EXAMPLES
To obtain the zone example.com from the server 192.168.9.8: getzone example.com 192.168.9.8 To obtain the zone example.org from the server 10.9.8.78 using a query class of 255: getzone example.com 10.9.8.78 255 SEE ALSO
