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.
