|

|
||||
<para>The automatic mounter daemon,
|
||||
<application>amd</application>, automatically mounts a remote
|
||||
file system whenever a file or directory within that file
|
||||
system is accessed. File systems that are inactive for a
|
||||
period of time will be automatically unmounted by
|
||||
<application>amd</application>.</para>
|
||||
|
||||
<para>This daemon provides an alternative to modifying
|
||||
<filename>/etc/fstab</filename> to list every client. It
|
||||
operates by attaching itself as an <acronym>NFS</acronym>
|
||||
server to the <filename>/host</filename> and
|
||||
<filename>/net</filename> directories. When a file is
|
||||
accessed within one of these directories,
|
||||
<application>amd</application> looks up the corresponding
|
||||
remote mount and automatically mounts it.
|
||||
<filename>/net</filename> is used to mount an exported file
|
||||
system from an <acronym>IP</acronym> address while
|
||||
<filename>/host</filename> is used to mount an export from a
|
||||
remote hostname. For instance, an attempt to access a file
|
||||
within <filename>/host/foobar/usr</filename> would tell
|
||||
<application>amd</application> to mount the
|
||||
<filename>/usr</filename> export on the host
|
||||
<systemitem>foobar</systemitem>.</para>
|
||||

||||

||||
<title>Mounting an Export with
|
||||
<application>amd</application></title>
|
||||
|
||||
<para>In this example, <command>showmount -e</command> shows
|
||||
the exported file systems that can be mounted from the
|
||||
<acronym>NFS</acronym> server,
|
||||
<systemitem>foobar</systemitem>:</para>
|
||||
|
||||
<screen>&prompt.user; <userinput>showmount -e foobar</userinput>
|
||||
Exports list on foobar:
|
||||
/usr 10.10.10.0
|
||||
/a 10.10.10.0
|
||||
&prompt.user; <userinput>cd /host/foobar/usr</userinput></screen>
|
||||
</example>
|
||||
|
||||
<para>The output from <command>showmount</command> shows
|
||||
<filename>/usr</filename> as an export. When changing
|
||||
directories to <filename>/host/foobar/usr</filename>,
|
||||
<application>amd</application> intercepts the request and
|
||||
attempts to resolve the hostname
|
||||
<systemitem>foobar</systemitem>. If successful,
|
||||
<application>amd</application> automatically mounts the
|
||||
desired export.</para>
|
||||
|
||||
<para>To enable <application>amd</application> at boot time, add
|
||||
this line to <filename>/etc/rc.conf</filename>:</para>
|
||||
|
||||
<programlisting>amd_enable="YES"</programlisting>
|
||||
|
||||
<para>To start <application>amd</application> now:</para>
|
||||
|
||||
<screen>&prompt.root; <userinput>service amd start</userinput></screen>
|
||||
|
||||
<para>Custom flags can be passed to
|
||||
<application>amd</application> from the
|
||||
<varname>amd_flags</varname> environment variable. By
|
||||
default, <varname>amd_flags</varname> is set to:</para>
|
||||
|
||||
<programlisting>amd_flags="-a /.amd_mnt -l syslog /host /etc/amd.map /net /etc/amd.map"</programlisting>
|
||||
|
||||
<para>The default options with which exports are mounted are
|
||||
defined in <filename>/etc/amd.map</filename>. Some of the
|
||||
more advanced features of <application>amd</application> are
|
||||
defined in <filename>/etc/amd.conf</filename>.</para>
