The maps are created from local source files using the .Xr yp_mkdb 8 utility. The utility will prompt the user for a list of servers that support the specified domain; this list is used to populate the ypservers map. .Pp On a slave server, .Nm creates the .Pa /var/yp/$DOMAINNAME , populates it with copies of the NIS maps from the master. The maps are obtained from the master using the .Xr ypxfr 8 utility. The .Nm utility obtains the list of maps to transfer in one of two ways: if the system is configured as an NIS client and is bound to the master server, .Nm is able to use the .Xr ypwhich 1 utility to obtain a list of maps exported by the master server. If the system is not configured as a client of the NIS master, .Nm uses a hardcoded list of maps, some of which may or may not actually exist on the master. The system administrator can edit the .Nm script and modify the map list if necessary. Otherwise, individual maps can be transferred manually from the master using .Xr ypxfr 8 . .Sh OPTIONS The .Nm utility supports the following options: .Bl -tag -width indent .It Fl m Op Ar domainname Set up a master server. By default, .Nm sets up a server for the system default domain. The user can override this default by specifying .Ar domainname explicitly. Maps are constructed from scratch using local files as templates using the .Xr yp_mkdb 8 utility. .It Fl s Ar master_server Op Ar domainname Set up a slave server using .Ar master_name as the master. Maps are copied from .Ar master_server to the slave using .Xr ypxfr 8 . By default, .Nm sets up a server for the system default domain. The user can override this default by specifying .Ar domainname explicitly. .It Fl u Op Ar domainname Update the ypservers map on the master server. When a new slave server is added to a domain, its hostname must be added to the ypservers map so that .Xr yppush 8 can propagate updates on the master to all of the slaves. .El .Sh FILES .Bl -tag -width /var/yp/master.passwd -compact .It Pa /etc/bootparams Bootparams source file .It Pa /etc/ethers Ethers data source file .It Pa /etc/eui64 EUI64 data source file .It Pa /etc/group Group source file .It Pa /etc/hosts Hostname/IP address source file .It Pa /etc/netid RPC netid source file .It Pa /etc/networks Networks source file .It Pa /etc/protocols Protocols source file .It Pa /etc/publickey RPC public key/secret key source file .It Pa /etc/services Services data source file .It Pa /etc/shells Shells source file .It Pa /var/yp/master.passwd Passwd database source file .It Pa /var/yp/netgroup Netgroup data source file .It Pa /var/yp/ypservers Ypservers source file (generated by .Nm ) .El .Sh SEE ALSO .Xr mknetid 8 , .Xr revnetgroup 8 , .Xr yp 8 , .Xr yp_mkdb 8 , .Xr yppush 8 , .Xr ypserv 8 , .Xr ypxfr 8 .Sh HISTORY This version of .Nm is based on the .Nm script in .Ox .
