One is the user interface called the \fIresolver\fP which consists of a group of routines that reside in the C library \fI/lib/libc.a\fP. Second is the actual server called \fInamed\fP. This is a daemon that runs in the background and services queries on a given network port. The standard port for UDP and TCP is specified in \fI/etc/services\fP. .sh 2 "Resolver Routines in libc" .pp When building your 4.3BSD system you may either build the C library to use the name server resolver routines or use the host table lookup routines to do host name and address resolution. The default resolver for 4.3BSD uses the name server. Newer BSD systems include both name server and host table functionality with preference given to the name server if there is one or if there is a \fI/etc/resolv.conf\fP file. .pp Building the C library to use the name server changes the way \fIgethostbyname\fP\|(3N), \fIgethostbyaddr\fP\|(3N), and \fIsethostent\fP\|(3N) do their functions. The name server renders \fIgethostent\fP\|(3N) obsolete, since it has no concept of a next line in the database. These library calls are built with the resolver routines needed to query the name server. .pp The \fIresolver\fP contains functions that build query packets and exchange them with name servers. .pp Before building the 4.3BSD C library, set the variable \fIHOSTLOOKUP\fP equal to \fInamed\fP in \fI/usr/src/lib/libc/Makefile\fP. You then make and install the C library and compiler and then compile the rest of the 4.3BSD system. For more information see section 6.6 of ``Installing and Operating 4.3BSD on the VAX\(dd''. .(f \(ddVAX is a Trademark of Digital Equipment Corporation .)f .pp If your operating system isn't VAX\(dd 4.3BSD, it is probably the case that your vendor has included \fIresolver\fP support in the supplied C Library. You should consult your vendor's documentation to find out what has to be done to enable \fIresolver\fP support. Note that your vendor's \fIresolver\fP may be out of date with respect to the one shipped with \s-1BIND\s+1, and that you might want to build \s-1BIND\s+1's resolver library and install it, and its include files, into your system's compile/link path so that your own network applications will be able to use the newer features.
