  \begin{itemize}
  \item Especially important are the two online books:

    \item \url{http://au1.samba.org/samba/docs/man/Samba3-HOWTO/}, and

\section{NFS}
\label{sec:nfs}


\subsection{About NFS}
\label{sec:about-nfs}


\begin{frame}
  \frametitle{NFS}%
  \framesubtitle{About}%
  \begin{itemize}
  \item ``Network File System''
  \item Extremely widely used protocol for sharing files between Unix
    machines
  \item Built over RPC
  \item Almost always uses UDP
  \item Unlike alternatives, the NFS protocol is
    \textbf{stateless}---the server can reboot and the client carries
    on
  \item NFSv2 is very simple; v3 is an evolution of v2; v4 is complex
    (and stateful)
  \end{itemize}
\end{frame}

\subsection{NFS on client}
\label{sec:mount}


\begin{frame}[fragile]
  \frametitle{NFS}%
  \framesubtitle{Client-side usage}%
\begin{semiverbatim}
mount -o \textit{options} \textit{server}:/path /mnt_point
\small
# typical /etc/fstab line - see nfs(5)
server:/exports/home /home nfs rw,intr,rsize=8192,wsize=8192
\end{semiverbatim}
  Some options:
  \begin{description}
  \item[rsize/wsize] Read/write size
  \item[intr] Allow signals to interrupt timed-out operations
  \item[soft] Don't retry indefinitely
  \end{description}
\end{frame}

\subsection{NFS: server configuration}
\label{sec:nfs-server-config}


\begin{frame}[fragile]
  \frametitle{NFS}%
  \framesubtitle{Server-side configuration}%
  \texttt{/etc/exports} controls what gets exported to where
\begin{semiverbatim}
# /etc/exports.  See exports(5)
/home   10.0.128.0/24(rw,no_root_squash)
/cdrom  *(ro,all_squash)
\end{semiverbatim}
Information is actually communicated to mountd and kernel NFS server
via \textbf{exportfs}(8)
\par
\textbf{Note:} No whitespace is allowed between client and client
options
\par
(\textbf{showmount}(8) will query this information from a server)
\end{frame}

\section{Samba}
\label{sec:samba}

\subsection{About Samba}
\label{sec:about-samba}


\begin{frame}[fragile]
\frametitle{Samba}%
\framesubtitle{About}%
\begin{itemize}
\item Implementation of Windows networking protocols (SMB/CIFS, NMB)
  for Unix
\item Samba version 3 (just released) gives PDC/BDC functionality, NT4
  domain member support, much improved printing, etc
\item Full suite of tools, including smbd and nmbd daemons, but also
  client tools: smbclient, rpcclient, net, smbstatus, nmblookup,
  smbtar, smbspool, etc
\end{itemize}
\end{frame}

\section{\texttt{smb.conf}}
\label{sec:smb.conf}


\begin{frame}[fragile]
  \frametitle{Samba}%
  \framesubtitle{\texttt{smb.conf}}%
  Configured through \texttt{/etc/samba/smb.conf}
  \par
  \texttt{win.ini}-esque sections describing shares
\begin{semiverbatim}
[public]
comment = Public files
path = /home/ftp/pub
read only = yes
guest ok = yes
\end{semiverbatim}
  Various \%X string substitutions available (see smb.conf(5))
\end{frame}

\subsection{smb.conf sections}
\label{sec:smb.conf-sections}

\begin{frame}
  \frametitle{Samba}%
  \framesubtitle{\texttt{smb.conf} -- Special sections}%
  \begin{description}
  \item[\texttt{[global]}] Global configuration
  \item[\texttt{[homes]}] Triggers creation of automatic user home
    directory shares
  \item[\texttt{[printers]}] Triggers creation of printer shares for
    each system printer
  \end{description}
\end{frame}

\subsection{Web configuration with swat}
\label{sec:swat}

\begin{frame}
  \frametitle{Samba}%
  \framesubtitle{SWAT}%
  \begin{itemize}
  \item ``Samba Web Administration Tool''
  \item Usual install is \url{http://localhost:901/}
  \item Easy to use, links to relevant documentation, etc.
  \item Rewrites \texttt{smb.conf}, loses comments, reorders and
    destroys hand crafted directives such as \texttt{include}
  \end{itemize}
\end{frame}
