NAME

       netgroup - list of network groups

DESCRIPTION

       File  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 classifies machines; for remote logins and remote shells, it classifies users.

       Each line of the file defines a group.  The items on a line may be separated by a combination of one or more spaces or tabs.  The line  has
       the format

	      groupname member1 member2 ...

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

       If any of these three fields is left empty, it signifies a wildcard.  Thus

       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.

       Machine belongs to the group in the domain but no users belong to it.  Similarly, the user belongs to  the  group  in  the  domain  but	no
       machines belong to it.

       Note,  the  domainname field must match the current domain name (as returned by the 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 it does, the groups are stored in the following NIS maps:

NAME

       netgroup - List of network groups

DESCRIPTION

       The netgroup 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 netgroup file is used to classify machines; for remote logins and remote shells, it is used to  clas-
       sify users.  Each line of the netgroup file defines a group and has the following format:

       groupname member_1 ... member_n

       Each member can be either another group name or a combination of the host name, user name, and domain name in the following format:

       (hostname, username, domainname)

       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 netgroup 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 NIS database 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 /etc/netgroup using makedbm(8).
