HP-UX IP Address and Client Management Administrator's Guide (October 2009)
listen-on [port ip_port] {address_match_list};
The listen-on option specifies the interfaces and ports from which the server answers queries.
You can specify an optional port and an address_match_list in the listen-on option. The
server listens on all interfaces allowed by the address_match_list.
If you do not specify a port, port 53 is used. If you do not specify the listen-on option, the
server listens on port 53 on all interfaces. You can specify multiple listen-on statements.
An example listen-on option is as follows:
listen-on { 5.6.7.8; };
listen-on port 1234 { 11.2.3.4; 1.2/16; };
Zone Transfer Options
Table 1-8 describes the zone transfer options.
Table 1-8 Zone Transfer Options
DescriptionOption
This option defines a global list of IP addresses of name servers to
which NOTIFY messages are sent, in addition to the servers listed in
the zone's NS records when a fresh copy of the zone is loaded.
also-notify { ( ip_addr [ port
ip_port ] ; )... };
This option specifies an alternate transfer source IPv4 address, if the
transfer source address listed in transfer-source option fails and if
the use-alt-transfer-source option is set.
alt-transfer-source ( ip4_addr |
* ) [ port ip_port ];
This option specifies an alternate transfer source IPv6 address, if the
transfer source address listed in transfer-source-v6 fails and if
use-alt-transfer-source is set.
alt-transfer-source-v6 (ip6_addr|*
) [ port ip_port ];
Specifies the time period after which inbound zone transfers
(named-xfer processes) must be terminated. The default value is
120 minutes (2 hours).
max-transfer-time-in number;
This option terminates inbound zone transfers making no progress
in the specified period. The default value is 60 minutes.
max-transfer-idle-in;
This option terminates outbound zone transfers running longer than
the specified time. The default value is 120 minutes.
max-transfer-time-out;
This option terminates outbound zone transfers making no progress
in the specified period. The default value is 60 minutes.
max-transfer-idle-out;
The server supports two zone transfer methods: one-answer and
many-answers. The first method uses one DNS message for every
resource record transferred. The second method packs many resource
records into one message. many-answers is more efficient than
one-answer, but is only compatible with BIND 8.1.2 and patched
versions of BIND 4.9.7. The default is one-answer.
You can override a transfer-format statement with a server
statement on a per-server basis.
transfer-format (one-answer |
many-answers );
This option specifies the maximum number of inbound zone transfers
that can run concurrently. The default value is 10. Increasing the value
of the transfer-in option speeds up the coverage of slave zones.
It also increases the load on the local system.
transfer-in number;
This option specifies the maximum number of outbound zone transfer
that run concurrently.
transfers-out number;
