NAME
ypfiles − Network Information Service Version 2, formerly knows as YP
DESCRIPTION
The NIS network information service uses a distributed, replicated database of dbm files (in ASCII form) contained in the /var/yp directory hierarchy on each NIS server. NIS has been replaced by NIS+, the new version of the Network Information Service. See nis+(1). This release only supports the client functionality of NIS, (see ypclnt(3NSL)). The client functions are either supported by the ypserv process running on a machine with an earlier version of SunOS or by the NIS+ server in "YP-compatibility" mode, (see rpc.nisd(1M)).
A dbm database served by the NIS server is called an NIS map. An NIS domain is a subdirectory of /var/yp containing a set of NIS maps on each NIS server.
Standard nicknames are defined in the file /var/yp/nicknames. These names can be used in place of the full map name in the ypmatch and ypcat commands. The command ypcat -x can be used to display the current set of nicknames. The command ypwhich -m can be used to display all the available maps. Each line of the nickname file contains two fields separated by white space. The first field is the nickname and the second field is the name of the map that it expands to. The nickname cannot contain a ".".

NOTES
The NIS+
server, rpc.nisd, when run in "YP-compatibility
mode", can support NIS clients only for the standard
NIS maps listed below, provided that it has been set up to
serve the corresponding NIS+ tables using
nissetup(1M) and nisaddent(1M). The NIS+
server should serve the directory with the same name (case
sensitive) as the domainname of the NIS client. NIS+ servers
use secure RPC to verify client credentials but the NIS
clients do not authenticate their requests using secure RPC.
Therefore, NIS clients can look up the information stored by
the NIS+ server only if the information has "read"
access for an unauthenticated client (i.e. one with
"nobody" NIS+ credentials).
