NAME
rfmaster - Remote File Sharing name server master file
DESCRIPTION
The rfmaster file is an ASCII file that identifies the hosts
that are responsible for providing primary and secondary
domain name service for Remote File Sharing domains. This
file contains a series of records, each terminated by a
newline; a record may be extended over more than one line by
escaping the newline character with a backslash ("\"). The
fields in each record are separated by one or more tabs or
spaces. Each record has three fields:
name type data
The type field, which defines the meaning of the name and
data fields, has three possible values:
p The p type defines the primary domain name server.
For this type, name is the domain name and data is the
full host name of the machine that is the primary name
server. The full host name is specified as
domain.nodename. There can be only one primary name
server per domain.
s The s type defines a secondary name server for a
domain. Name and data are the same as for the p type.
The order of the s entries in the rfmaster file
determines the order in which secondary name servers
take over when the current domain name server fails.
a The a type defines a network address for a machine.
Name is the full domain name for the machine and data
is the network address of the machine. The network
address can be in plain ASCII text or it can be
preceded by a \x to be interpreted as hexadecimal
notation. (See the documentation for the particular
network you are using to determine the network
addresses you need.)

There are at least two lines in the rfmaster file per domain
name server: one p and one a line, to define the primary
and its network address. There should also be at least one
secondary name server in each domain.
This file is created and maintained on the primary domain
name server. When a machine other than the primary tries to
start Remote File Sharing, this file is read to determine
the address of the primary. If rfmaster is missing, the -p
option of rfstart must be used to identify the primary.
After that, a copy of the primary's rfmaster file is
automatically placed on the machine.
Domains not served by the primary can also be listed in the
rfmaster file. By adding primary, secondary, and address
information for other domains on a network, machines served
by the primary will be able to share resources with machines
in other domains.
A primary name server may be a primary for more than one
domain. However, the secondaries must then also be the same
for each domain served by the primary.
EXAMPLE
An example of an rfmaster file is shown below. (The network
address examples, comp1.serve and comp2.serve, are STARLAN
network addresses.)
ccs p ccs.comp1
ccs s ccs.comp2
ccs.comp2 a comp2.serve
ccs.comp1 a comp1.serve
NOTE: If a line in the rfmaster file begins with a #
character, the entire line will be treated as a comment.
