DNS BIND/iX and Syslog/iX

DNS BIND, which stands for Berkeley Internet Name Domain, is an

implementation of the Domain Name System (DNS) and is the most

common use of the Domain Name System (DNS). Now, the complete

implementation of DNS BIND/iX runs on an MPE/iX shell operation

system on MPE/iX release 6.0. Initially, DNS BIND/iX was written for

UNIX; however, the latest version of DNS BIND/iX 8.1.1 runs on

MPE/iX systems.

Overview of DNS BIND/iX

BIND DNS/iX is a domain name system which consists of a

client-server mechanism. The name servers comprise the server half of

the DNS’s client-server mechanism. The name server is the NM

program NAMED which maintains information about some part of the

DNS called a zone and has capabilities to retrieve information

regarding other zones. The clients are resolver routines provided as

NMRL libraries. The resolvers are clients that query the name servers,

interpret the responses and send the answers to the requester.

BIND DNS/iX makes your domain names visible to the internet as well

as handling client requests to resolve domain names within your

domain and external domains. Prior to DNS BIND/iX, the HP3000

users had to rely on other machines or other operating system to host

their organization DNS information. Now, you can host it on HP3000

systems.

Overview of Syslog/iX

Syslog is the standard event logging system for Syslog/iX UNIX, now

the Syslog/iX can run on the MPE/iX shell operating system on MPE/iX

release 6.0. With the features of Syslog/iX available on MPE/iX

systems, the event messages can be logged to ﬁles, terminal devices, or

even forward to other syslog systems. Syslog/iX can accept data from

the local system via an AF_UNIX socket or from any system on the

network via an AF_INET UDP socket on port 514. DNS BIND/iX uses

Syslog/iX as the event logging subsystem.
