DESCRIPTION
 ypinit initializes the files and directories that are required for a NIS client or server.
If domainname isn't specified, the default domain (as returned by domainname(1)) is used.
The following options are available:
- 
-c
- 
Create a NIS client. Initializes /var/yp/binding/<domain>.ypservers to contain a list of ypservers for ypbind(8) to connect to.
- 
-l server1,...,serverN
- 
Set the list of client servers from the command line rather than prompting for them interactively.  The format is a comma separated list of server names with no spaces.
- 
-m
- 
Create a master NIS server. Generates map data from local files (/etc/master.passwd, /etc/group, etc.).
- 
-s master_server
- 
Create a slave server. Downloads the maps from master_server, which should be the active master NIS server.
To rebuild or refresh the maps for the NIS domain <domain>, change to the /var/yp/<domain> directory and run make.
