NAME
netgroup - network groups data base
SYNOPSIS
/etc/netgroup
DESCRIPTION
netgroup defines network wide groups used for access permission checking
during remote mount request processing. Each line defines a group and has the
format:
groupname
member
-
list
Each element in member-list is either another group name or a triple of the form:
(
hostname
,
username
,
domainname
)
The
hostname
entry must be fully qualified if the specified host is not in the local
domain.
The filer can also use the netgroup NIS map.
Since the filer uses netgroups only in /etc/exports (see exports), the
username
entry is ignored. The
domain_name
field refers to the domain in which the net-
group entry is valid. It must either be empty or be the local domain, otherwise
the netgroup entry is ignored. This allows a single /etc/netgroup file to be used
for filers in multiple domains.
EXAMPLE
This is a typical netgroup file:
trusted_hosts (adminhost,,) (group1,,) (group2,,) (group3,,)
untrusted_hosts (group4,,) (group5,,) (group6,,)
all_hosts trusted_hosts untrusted_hosts
With this netgroup file it might make sense to modify /etc/exports to export
/ on the filer only to
trusted
_
hosts
, but to export /home to
all
_
hosts
.
