Name
       netgroup - list of network groups

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

       groupname member1,...,member_n

       Each  member  is either another group name or a combination of the host
       name, user name, and domain name.

       Any of the three fields can be empty,  in  which	 case  a  wildcard  is
       assumed.	 For example, to define a group to which everyone belongs, the
       following entry could appear in the file:
       universal (,,)

       Field names that begin with something other than a  letter,  digit,  or
       underscore (such as ``-'') work in the opposite way.  For example:
       justmachines   (analytica,-,suez)
       justpeople     (-,babbage,suez)

       The  machine  analytica belongs to the group justmachines in the domain
       suez, but no users belong to it.	 Similarly, the user  babbage  belongs
       to  the	group justpeople in the domain suez, but no machines belong to
       it.

       Network groups are part of the Yellow Pages data base and are  accessed
       through these files:

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

       These files can be created from using

Files

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