ypinit
YPINIT(8) BSD System Manager's Manual YPINIT(8)
NAME
ypinit -- initialize NIS subsystem
SYNOPSIS
ypinit -c [domainname] [-l server1,...,serverN]
ypinit -m [domainname] [-l server1,...,serverN]
ypinit -s master_server [domainname] [-l server1,...,serverN]
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.
FILES
/var/yp master NIS directory; contains the template makefiles.
/var/yp/<domain> directory to store NIS maps for <domain>.
/var/yp/binding/<domain>.ypservers
list of NIS servers to bind to.
