netgroup(4)                                                     netgroup(4)




 NAME    [Toc]    [Back]
      netgroup - list of network groups

 DESCRIPTION    [Toc]    [Back]
      File /etc/netgroup defines network-wide groups, and is used for
      permission checking when executing remote mounts, remote logins, and
      remote shells.  For remote mounts, the information in netgroup
      classifies machines; for remote logins and remote shells, it
      classifies users.  Each line of the netgroup file defines a group and
      has the format

           groupname  member1  member2  ...

      where memberi is either another group name, or a triple.

           (hostname, username, domainname)

      If any of these three fields are left empty, it signifies a wild card.
      Thus

           universal (,,)

      defines a group to which everyone belongs.  Field names that begin
      with something other than a letter, digit or underscore (such as -) do
      not match any value.  For example, consider the following entries.

           justmachines     (analytica,-,YOURDOMAIN)
           justpeople       (-,root,YOURDOMAIN)

      Machine analytica belongs to the group justmachines in the domain
      YOURDOMAIN, but no users belong to it.  Similarly, the user root
      belongs to the group justpeople in the domain YOURDOMAIN, but no
      machines belong to it.

      Note, the domain name field must match the current domain name (as
      returned by the domainname command), or the entry is not matched.
      Also, the user-name field is ignored for remote mounts.  Only the
      hostname and domainname are used.

      The Network Information Service (NIS) can serve network groups.  When
      so used, they are stored in the following NIS maps.

           netgroup
           netgroup.byuser
           netgroup.byhost

      Information Service.
