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 memberi 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(8).
