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

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) COPYRIGHT
