DNS BIND/iX

Overview of DNS BIND/iX

In this implementation of BIND 8.1.1, the conﬁguration and data ﬁles

for the DNS server are found under the /BIND/PUB directory of the

POSIX name space, though the DNS server is started by running a job

from the MPE/iX name space — JNAMED.PUB.BIND which runs program

NAMED.PUB.BIND.

The NAMED program maintains a cache of information, taken initially

from its zone ﬁles (database ﬁles) augmented by information which it

has retrieved from other DNS servers on the network.

Syslog is the standard event logging subsystem for UNIX, which has

now been implemented as Syslog/iX on MPE/iX 6.0 running in the

POSIX environment. DNS BIND/iX server logging is handled by

Syslog/iX. In order to run the DNS server, you will ﬁrst conﬁgure and

start Syslog/iX. Details on conﬁguring and running Syslog/iX can be

found in Appendix E , “Conﬁgure and Run Syslog/iX,” of this manual.

The client (resolver) code has already been implemented in earlier

releases of MPE/iX via library routines and the conﬁguration ﬁle

RESLVCNF.NET.SYS (linked to /etc/resolv.conf). RESLVCNF.NET.SYS

contains information about the domain of the client host and the IP

addresses of the local DNS servers who can be queried for information.
