netgroup

netgroup(5yp)															     netgroup(5yp)

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/netgroup
       /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
