domainname(1M) domainname(1M)
NAME
domainname - get/set name of current secure RPC domain
SYNOPSIS
domainname [ newname ]
DESCRIPTION
The domainname command is used on secure RPC machines. With no
argument, the name of the machine's secure RPC domain is written to
standard output.
root privileges are required to use the domainname command with an
argument. In this form, the command sets the name of the secure RPC
domain to newname. newname may be up to 255 characters long.
domainname is normally run by the network administrator on all
machines using secure RPC to set the name of the secure RPC domain.
To use secure RPC, machines must have a secure RPC domain name.
NOTES
Secure RPC domain names are not related to and should not be confused
with RFS domains.
The RPC package expects the newname argument to be a valid filename
for the underlying file system in use on the networked machines using
secure RPC. For example, machines based on the s5 file system should
not have domain names longer than 14 characters in length or problems
may occur when using secure RPC.
The secure RPC domain name set by domainname will not be remembered
across reboots. To give a machine a "permanent" name, set the
SRPCDOMAIN tunable in /etc/master.d/kernel to the secure RPC domain
name.
