 <title>The &infocenter;</title>
 
 <para>
 The &infocenter; provides you with a centralized and convenient
 overview of your system and desktop environment.
 </para>
 
 <para>
 The information center is made up of multiple modules.  Each module is a
 separate application, but the information center organizes all of these
 programs into a convenient location.
 </para>
 
 <para>
 This next section details the use of the information center itself.  For
 information on individual modules, please see <link linkend="module">Default
 &infocenter; Modules</link>.

 <sect1 id="kcm_memory">
 <title>Memory Information Module</title>
 
 <para>This module displays the current memory usage.  It is updated
 constantly, and can be very useful for pinpointing bottlenecks when certain
 applications  are executed.</para>
 
 <sect2 id="memory-intro">
 <title>Memory Types</title>
 
 <para>The first thing you must understand, is there are two types of
 <quote>memory</quote>, available to the operating system and the programs
 that run within  it.</para>
 
 <para>The first type, is called physical memory.  This is the memory located
 within the memory chips, within your computer.  This is the
 <acronym>RAM</acronym> (for Random Access Memory) you bought when you
 purchased your  computer.</para>
 
 <para>The second type of memory, is called virtual or swap memory.  This
 block of memory, is actually space on the hard drive.  The operating
 system reserves a space on the hard drive for <quote>swap space</quote>.
 The operating system can use this virtual memory (or swap space), if it
 runs out of physical memory.  The reason this is called
 <quote>swap</quote> memory, is the operating system takes some data that
 it doesn't think you will want for a while, and saves that to disk in
 this reserved space.  The operating system then loads the new data you
 need right now.  It has <quote>swapped</quote> the not needed data, for
 the data you need right now.  Virtual or swap memory is not as fast as
 physical memory, so operating systems try to keep data (especially often
 used data), in the physical memory.</para>
 
 <para>The total memory, is the combined total of physical memory and
 virtual memory.</para>
 
 </sect2>
 
 <sect2 id="memory-use">
 <title>Memory Information Module</title>
 
 <para>This window is divided into a top and bottom section</para>
 
 <para>The top section shows you the total physical memory, total free
  physical memory, shared memory, and buffered memory.</para>
 
 <para>All four values are represented as the total number of bytes, and
  as the number of megabytes (1 megabyte = slightly more than 1,000,000
  bytes)</para>
 
 <para>The bottom section shows you three graphs:  </para>
 
 <itemizedlist>
 <listitem><para><guilabel>Total Memory</guilabel> (this is the combination of physical and  virtual memory).</para></listitem>
 <listitem><para><guilabel>Physical Memory</guilabel></para></listitem>
 <listitem><para>Virtual memory, or <guilabel>Swap Space</guilabel>.</para></listitem>
 </itemizedlist>
 
 <para>The grey areas are free, and the blue and green areas are used.</para>
 <tip><para>The exact values of each type of memory are not critical, and
  they change regularly.  When you evaluate this page, look at
  trends.</para>
 
 <para>Does your computer have plenty of free space (grey areas)?  If
  not, you can increase the swap size or increase the physical
  memory.</para>
 
 <para>Also, if your computer seems sluggish: is your physical memory
  full, and does the hard drive always seem to be running?  This suggests
  that you do not have enough physical memory, and your computer is
  relying on the slower virtual memory for commonly used data. Increasing
  your physical memory will improve the responsiveness of your
  computer.</para></tip>

 <para>This page displays information about the Interrupt Request
 Lines in use, and the devices that use them.</para>
 
 <para>An <acronym>IRQ</acronym> is a hardware line used in a
 <acronym>PC</acronym> by (<acronym>ISA</acronym> bus) devices like
 keyboards, modems, sound cards, &etc;, to send interrupt signals to the
 processor to tell it that the device is ready to send or accept data.
 Unfortunately, there are  only sixteen <acronym>IRQ</acronym>'s (0-15)
 available in the i386 (<acronym>PC</acronym>) architecture for sharing among
 the various <acronym>ISA</acronym> devices.</para>
 
 <para>Many hardware problems are the result of <acronym>IRQ</acronym>
 conflicts, when two devices try to use the same <acronym>IRQ</acronym>, or
 software is misconfigured to use a different <acronym>IRQ</acronym> from the
 one a device is actually configured for.</para>

 direct connection that allows devices to transfer data to and from
 memory without going through the processor. Typically, i386-architecture
 systems (<acronym>PC</acronym>'s) have eight <acronym>DMA</acronym>
 channels (0-7).</para>

 <para>This page displays information about the I/O ports.</para>
 
 <para>I/O Ports are memory addresses used by the processor for direct
 communication with a device that has sent an
 interrupt signal to the processor.</para>
 
 <para>The exchange of commands or data between the processor and the device
 takes place through the I/O port address of the device, which is a
  hexadecimal
 number.  No two devices can share the same I/O port.  Many devices use
  multiple
 I/O port addresses, which are expressed as a range of hexadecimal
 numbers.</para>

 <title>&Samba; Status Information Module</title>
 
 <para>The &Samba; and &NFS; Status Monitor is a front end
 to the programs <command>smbstatus</command> and
 <command>showmount</command>.  Smbstatus reports on current &Samba;
 connections, and is part of the suite of &Samba; tools, which implements
 the &SMB; (Server Message Block) protocol, also called
 the NetBIOS or LanManager protocol.</para>
 
 <para>This protocol can be used to provide printer sharing or drive
 sharing services on a network including machines running the various
 flavors of &Microsoft; &Windows;.</para>
 
 <para><command>showmount</command> is part of the &NFS;
 software package. &NFS; stands for Network File System
 and is the traditional &UNIX; way to share folders over the
 network. In this case the output of <command>showmount</command>
 <option>-a localhost</option> is parsed. On some systems showmount is in
 <filename class="directory">/usr/sbin</filename>, check if you have
 showmount in your <envar>PATH</envar>.</para>
 
 <sect3 id="smb-exports">
 <title>Exports</title>
 
 <para>On this page you can see a big list which shows the currently
 active connections to &Samba; shares and &NFS; exports of
 your machine.  The first column shows you whether the resource is a &Samba;
 (&SMB;) share or a &NFS; export. The
 second column contains the name of the share, the third the name of the
 remote host, which accesses this share. The remaining columns have only
 a meaning for &Samba;-shares.</para>
 
 <para>The fourth column contains the User <abbrev>ID</abbrev> of the
 user, who accesses this share. Note that this does not have to be equal
 to the &UNIX; user <abbrev>ID</abbrev> of this user. The same applies
 for the next column, which displays the group <abbrev>ID</abbrev> of the
 user.</para>
 
 <para>Each connection to one of your shares is handled by a single
 process (<command>smbd</command>), the next column shows the process
 <abbrev>ID</abbrev> (<acronym>pid</acronym>) of this
 <command>smbd</command>. If you kill this process the connected user
 will be disconnected. If the remote user works from &Windows;, as soon
 as this process is killed a new one will be created, so he will almost
 not notice it.</para>
 
 <para>The last column shows how many files this user has currently open.

 <para> Here you see which &Samba;- and &NFS;-shares from
 other hosts are mounted on your local system. The first column shows
 whether it is a &Samba;- or &NFS;-share, the second column
 displays the name of the share, and the third shows where it is
 mounted.</para>

 <para>This page presents the contents of your local &Samba; log file in a
 nice way. If you open this page, the list will be empty.  You have to
 press the <guibutton>Update</guibutton> button, then the &Samba; log file
 will be read and the results displayed. Check whether the &Samba; log file
 on your system is really at the location as specified in the input
 line. If it is somewhere else or if it has another name, correct
 it. After changing the file name you have to press
 <guibutton>Update</guibutton> again.</para>
 
 <para>&Samba; logs its actions according to the log level (see
 <filename>smb.conf</filename>).  If loglevel = 1, &Samba; logs only when
 somebody connects to your machine and when this connection is closed
 again. If log level = 2, it logs also if somebody opens a file and if he
 closes the file again.  If the log level is higher than 2, yet more
 stuff is logged.</para>
 
 <para>If you are interested in who accesses your machine, and which
 files are accessed, you should set the log level to 2 and regularly
 create a new &Samba; log file (&eg; set up a <command>cron</command> task
 which once a week moves your current &Samba; log file into another
 folder or something like that). Otherwise your &Samba; log file may
 become very big.</para>
 
 <para>With the four checkboxes below the big list you can decide, which
 events are displayed in the list. You have to press

 how often every single user opened each file.</para>
 
 <para>In the input lines <guilabel>Service/File</guilabel> and
 <guilabel>Host/User</guilabel> you can use the wildcards
 <literal>*</literal> and <literal>?</literal> in the same way you use
 them at the command line.  Regular expressions are not
 recognized.</para>
