Chapter 6. BIND 9 Conﬁguration Reference

transfer-source

transfer-source determines which local address will be bound to IPv4 TCP connections used to

fetch zones transferred inbound by the server. It also determines the source IPv4 address, and

optionally the UDP port, used for the refresh queries and forwarded dynamic updates. If not set, it

defaults to a system controlled value which will usually be the address of the interface "closest to"

the remote end. This address must appear in the remote end’s allow-transfer option for the zone

being transferred, if one is speciﬁed. This statement sets the transfer-source for all zones, but can

be overridden on a per-view or per-zone basis by including a transfer-source statement within the

view or zone block in the conﬁguration ﬁle.

transfer-source-v6

The same as transfer-source, except zone transfers are performed using IPv6.

notify-source

notify-source determines which local source address, and optionally UDP port, will be used to send

NOTIFY messages. This address must appear in the slave server’s masters zone clause or in an

allow-notify clause. This statement sets the notify-source for all zones, but can be overridden on a

per-zone / per-view basis by including a notify-source statement within the zone or view block in

the conﬁguration ﬁle.

notify-source-v6

Like notify-source, but applies to notify messages sent to IPv6 addresses.

6.2.14.7. Operating System Resource Limits

The server’s usage of many system resources can be limited. Scaled values are allowed when specifying

resource limits. For example, 1G can be used instead of 1073741824 to specify a limit of one gigabyte.

unlimited requests unlimited use, or the maximum available amount. default uses the limit that was in

force when the server was started. See the description of size_spec in Section 6.1.

The following options set operating system resource limits for the name server process. Some operating

systems don’t support some or any of the limits. On such systems, a warning will be issued if the

unsupported limit is used.

coresize

The maximum size of a core dump. The default is default.
