     NAME
          netgroup - list of network groups

     DESCRIPTION
          netgroup defines network-wide groups,  which  are  used  for
          permission checking when doing remote mounts, remote logins,
          and remote shells.  Each line of the netgroup file defines a
          group and has the format

             groupname member1 member2 ...

          where member1 is either another group name or  a  triple  of
          the form

               (hostname, username, domainname)

          Any of three fields can be empty, in which case it signifies
          a wild card.  Thus

             universal (,,)

          defines a group to which everyone belongs.

          Network groups are accessed through the yellow  pages.   The
          database  actually  used  by the yellow pages are in the two
          files

               /etc/yp/domainname/netg.dir
               /etc/yp/domainname/netg.pag

          These  files  can  be  created  from   /etc/netgroup   using
          makedbm(1M).
