NAMEnetgroup — list of network groups DESCRIPTIONFile /etc/netgroup 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 netgroup classifies machines; for remote logins and remote shells, it classifies users. Each line of the netgroup 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. (hostname, username, domainname) If any of these three fields is left empty, it signifies a wildcard. Thus universal (,,) 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. justmachines (analytica,-,YOURDOMAIN) justpeople (-,root,YOURDOMAIN) Machine analytica belongs to the group justmachines in the domain YOURDOMAIN, but no users belong to it. Similarly, the user root belongs to the group justpeople in the domain YOURDOMAIN, but no machines belong to it. Note, the domainname field must match the current domain name (as returned by the domainname command), or the entry is not matched. Also, the username 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: netgroup netgroup.byuser netgroup.byhost Refer to ypserv(1M) and ypfiles(4) for an overview of Network Information Service.
