the public and private keys from files in the working directory. In most cases, the key name
must be the server’s host name.
• port
This option specifies the port number.
The sortlist Statement
The response to a DNS query consists of multiple resource records forming a resource record
set. The name server replies to a query with a resource record set in an indeterminate order. The
client resolver code must rearrange the resource records appropriately on the local network
depending upon a particular preference.
You can use the sortlist statement to specify the preference of an IP address over other IP
addresses. The sortlist statement contains the address_match_list option, which is a list
of addresses that specify the preference. Each top-level statement in the sortlist statement
must be an explicit addresses_match_list with one or two elements. The first element, which
can be an IP address, IP prefix, acl name, or a nested address_match_list, is checked against
the source address of the query until a match is found.
When the source address of the query is matched, if the top-level statement contains only one
element, the actual element that matches the source address is used to select the address in the
response to move to the beginning of the response. Each top-level statement element is assigned
a distance, and the address in the response with the minimum distance is moved to the beginning
of the response. For more information on the sortlist statement, type man 1M named.conf
at the HP-UX prompt.
The server Statement
The server statement in the /etc/named.conf file defines the remote name server
characteristics. For example, if a name server is giving incorrect data, you can label the name
server to prevent further queries to it.
The server supports the following types of zone transfer methods, which you can define in the
transfer-format phrase in the server statement.
• transfer-format one-answer;
Each resource record receives its own DNS message. This format is widely accepted but not
efficient.
• transfer-format many-answers;
Each DNS message accommodates as many resource records as possible. This format is
efficient when compared to the transfer-format one-answer option.
You can specify any of the transfer-format options for a server using the transfer-format
option within the server statement. If you do not specify the transfer-format option, the
transfer-format specified by the options statement is used.
The server statement is of the following format:
server ip_addr {
[ bogus yes_or_no ; ]
[ edns yes_or_no ; ]
[ keys { string ; [ string ; ]... }; ]
[ provide-ixfr yes_or_no ; ]
[ request-ixfr yes_or_no ; ]
[ transfer-format ( one-answer | many-answers ) ; ]
[ transfer-source ( ip4_addr | * ) [ port ip_port ] ; ]
[ transfer-source-v6 ( ip6_addr | * ) [ port ip_port ] ; ]
[ transfers number ; ]
};
