netgroup(4)                                           netgroup(4)



     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:

                (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 these two
          files:

               /etc/yp/domainname/netgroup.dir
               /etc/yp/domainname/netgroup.pag

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

     FILES
          /etc/netgroup
          /etc/yp/domainname/netgroup.dir
          /etc/yp/domainname/netgroup.pag
