NAME
netgroup - List of network groups
DESCRIPTION
The netgroup file defines network-wide groups, used for permission
checking when performing remote mounts. For remote mounts, the
information in netgroup is used to classify machines. Each line of the
netgroup file defines a group and has the following format:
groupname member1 member2 ...
The membern parameter is either another group name, or a three-field entry
as follows:
(hostname, username, domainname)
An empty field in any of the three fields signifies a wild card. Thus the
following example defines a group to which everyone belongs:
universal (,,)
Field names beginning with something other than a letter, digit, or
underscore (_) work in the opposite way, as in the following examples:
justmachines (analytic,-,mkt)
justpeople (-,babbage,mkt)
The machine analytic belongs to the group justmachines in the domain mkt,
but no users belong to this group. Similarly, the user babbage belongs to
the group justpeople in the domain mkt, but no machines belong to this
group.
Network groups are contained in the Network Information Service (NIS)
database, and are accessed through the following files:
⊕ /etc/yp/domainname/netgroup.dir
⊕ /etc/yp/domainname/netgroup.pag
⊕ /etc/yp/domainname/netgrp.usr.dir
⊕ /etc/yp/domainname/netgrp.usr.pag
⊕ /etc/yp/domainname/netgrp.hst.dir
⊕ /etc/yp/domainname/netgrp.hst.pag
These files are created by NIS from /etc/netgroup using the makedbm
command.
