Bind 9 Administrator Reference Manual

Chapter 6. BIND 9 Conﬁguration Reference

version

The version the server should report via a query of name version.bind in class CHAOS. The

default is the real version number of this server.

directory

The working directory of the server. Any non-absolute pathnames in the conﬁguration ﬁle will be

taken as relative to this directory. The default location for most server output ﬁles (e.g. named.run)

is this directory. If a directory is not speciﬁed, the working directory defaults to ‘.’, the directory

from which the server was started. The directory speciﬁed should be an absolute path.

named-xfer

This option is obsolete. It was used in BIND 8 to specify the pathname to the named-xfer program.

In BIND 9, no separate named-xfer program is needed; its functionality is built into the name

server.

tkey-domain

The domain appended to the names of all shared keys generated with TKEY. When a client

requests a TKEY exchange, it may or may not specify the desired name for the key. If present, the

name of the shared key will be "client specified part" + "tkey-domain". Otherwise, the

name of the shared key will be "random hex digits" + "tkey-domain". In most cases, the

domainname should be the server’s domain name.

tkey-dhkey

The Difﬁe-Hellman key used by the server to generate shared keys with clients using the

Difﬁe-Hellman mode of TKEY. The server must be able to load the public and private keys from

ﬁles in the working directory. In most cases, the keyname should be the server’s host name.

dump-ﬁle

The pathname of the ﬁle the server dumps the database to when instructed to do so with rndc

dumpdb. If not speciﬁed, the default is named_dump.db.

memstatistics-ﬁle

The pathname of the ﬁle the server writes memory usage statistics to on exit. If not speciﬁed, the

default is named.memstats.

Note: Not yet implemented in BIND 9.
