NAME
rfmaster - Remote File Sharing name server master file
DESCRIPTION
Each transport provider used by Remote File Sharing has an associated
rfmaster file that identifies the primary and secondary name servers
for that transport provider. The rfmaster file ASCII 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. These values can appear in upper
case or lower case:
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 or \X to be
interpreted as hexadecimal notation. (See the documentation
for the particular network you are using to determine the
network addresses you need. In particular, see chapters 2,
10-12 of the Network User's and Administrator's Guide.)
If a line in the rfmaster file begins with a # character, the entire
line is treated as a comment.
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.
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 the associated rfmaster for a transport provider is
missing, use rfstart -p to identify the primary for that transport

provider. 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. There is an rfmaster file for each transport
provider.

An example of an rfmaster file is shown below. (The network address
examples, comp1.serve and comp2.serve, are TCP/IP network addresses.)
