netgroup



PURPOSE

Provides list of network groups.

DESCRIPTION

The netgroup facility defines network wide groups, used for permission checking
when doing remote mounts, remote logins and remote shells.  For remote mounts,
the information in netgroup is used to classify machines; for remote logins and
remote shells, it is used to classify users.  Each line of the netgroup file
defines a group and has the following format:

  groupname member1 member2...

where member1 is either another group name or:

  (hostname, username, domainname)

Any of these three fields may be empty, in which case it signifies a wildcard.
For example:

  biggroup (, ,)

defines a group to which everyone belongs.

A gateway machine should be listed under all possible names by which it may be
recognized.

  ying (gateway, ,) (gateway-rlt, ,)

Field names that begin with something other than a letter, digit or underscore
(such as a hyphen) work in the opposite fashion.  For example, consider the
following entries:

  groupa (sitea,-,la)
  groupb (-,george,la)

The machine sitea belongs to the group groupa in the domain la, but no users
belong to it.  Similarly, the user george belongs to the group groupb in the
domain la, but no machines belong to it.

The domainname field refers to the domain n where the entry is valid, not the
name containing the trusted host.
