  \frametitle{Optus Configuration Management}
  \begin{itemize}
  \item We use all free software
	\begin{itemize}
		\item except for Radiator and Netapps
	\end{itemize}
	\item We have about 800,000 ISP customers
        \item We support about 500 servers
        \item With from 5 to 12 people
        \item How do we do it?
  \end{itemize}
\end{frame}

\begin{frame}
   \frametitle{Conform}
	\begin{itemize}
	\item With Central configuration
        \item \ldots\, and \texttt{conform}.
	\item Configuration stored entirely in three files as a Perl hash!
	\item Specify configuration entirely in the \texttt{machines} file
        \item Software stored in CVS \ldots
	\item and as RPMs in our \texttt{apt} repository
        \item build servers provision installation with Kickstart
\end{itemize}
\end{frame}

\begin{frame}
	\frametitle{Replace a box}
     	\begin{itemize}
	\item Machines file entry specifies configuration already
	\item Machine has new disk --- kickstart it (uses PXE)
        \item Run \texttt{conform} on the box.
        \item All the required RPMs, CVS modules are installed
        \item All configuration is done completely
   	\item Even the firewall is configured for the applications
	\end{itemize}
\end{frame}


\begin{frame}
  \frametitle{Main Points}
  \begin{itemize}
  \item No configuration is done locally
  \item This is system administration done by programming
  \end{itemize}
\end{frame}
