defaultdomain

DEFAULTDOMAIN(5)					     Linux Programmer's Manual						  DEFAULTDOMAIN(5)

NAME

       defaultdomain - file which contains the NIS/YP domain name

DESCRIPTION

       /etc/defaultdomain is used by the boot scripts to set the NIS/YP domain name for a system as returned by the getdomainname(2) function. The
       file contains one line with the name of the domain.

       Unlike DNS hostnames and domain names, the NIS domain name is case-sensitive! The NIS domain name must not be the same as  the  DNS  domain
       name, but for some services like NIS+ it should be the same.

       Even if the domain name is often called NIS/YP domain name, it is also used from other protocols, not only NIS/YP.

FILES

       /etc/defaultdomain /etc/init.d/boot.localnet

SEE ALSO

       domainname(1), init.d(7), init(8), nisdomainname(1), ypdomainname(1), ypbind(8), ypserv(8), ypwhich(1)
