.sh 1 "Building a System with a Name Server"
.pp
BIND is composed of two parts. 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''.

.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may be out of date with respect to the one shipped with \s-1BIND\s+1, and that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.
