your web browser. Although most people use remote desktop tools only when absolutely
necessary, we believe that Guacamole must be aimed at becoming a primary means of accessing
desktops, and the interface is thus intended to be as seamless and unobtrusive as
possible.</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="home-screen"></a>Home screen</h2></div></div></div><p>Once you have successfully logged in, you will be taken to either the Guacamole home
screen, where all available connections are listed, or directly to a connection, if you
only have access to one connection.</p><p>The home screen will contain a list of all connections to which you have access, along
with thumbnails of any recently used or active connections. If you have access to a
large number of connections and wish to quickly locate a specific connection, you can
also enter search terms within the "Filter" field to filter the list of connections by
name.</p><div class="informalfigure"><div class="screenshot"><div class="mediaobject"><img src="images/guacamole-home-screen.png" width="450" /><div class="caption"><p>The Guacamole home screen. The user menu and several recently-used
connections are visible, along with one active connection.</p></div></div></div></div><p>Clicking on any connection will open that connection within the current window or tab,
but multiple connections can be used simultaneously. You can easily navigate back to the
home screen without disconnecting by using your browsers back button or the "Home"
button in the Guacamole menu. Each connection you use will remain active until
explicitly disconnected, or until you navigate away from Guacamole entirely. Active
connections can be seen as thumbnails updating in real-time on the home screen.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="user-menu"></a>User menu</h3></div></div></div><p>With the exception of the client screen discussed below, all Guacamole screens
contain a menu in the upper-right corner called the "user menu". This menu displays
your username and contains several options which depend on your user's level of
access:</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">Home</span></dt><dd><p>Navigates back to the home screen, if you are not already there. If

with some basic instructions:</p><div class="blockquote"><blockquote class="blockquote"><p>Text copied/cut within Guacamole will appear here. Changes to the text below will
affect the remote clipboard.</p></blockquote></div><p>The text area functions as an interface between the remote clipboard and the local
clipboard. Text from the local clipboard can be pasted into the text area, causing that
text to be sent to the clipboard of the remote desktop. Similarly, if you copy or cut
text within the remote desktop, you will see that text within the text area, and can
manually copy it into the local clipboard if desired.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="client-user-menu"></a>Disconnecting and navigation</h2></div></div></div><p>When you are done using the current connection, or you wish to navigate elsewhere

that allows you to explicitly close the current connection only. Clicking "Logout"
will also implicitly disconnect all active connections, including the current
connection.</p><p>Navigating back to the home screen or to the settings screen will not disconnect
you: your connection will continue running in the background while you change
settings or initiate another connection, and you can resume any active connection by
clicking on it within the home screen.</p></div></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="client-share-menu"></a>Sharing the connection</h2></div></div></div><p>If the Guacamole server is configured to allow connection sharing, and you have been
granted permission to share the current connection, an additional "Share" menu will
appear next to your username in the Guacamole menu. Clicking on this menu opens a list
of options for sharing the current connection.</p><div class="informalfigure"><div class="mediaobject"><img src="images/guac-menu-share.png" width="540" /></div></div><p>Clicking any of the options within the "Share" menu will immediately generate a unique
share link which can be distributed to anyone, even to users which do not otherwise have
accounts within the same Guacamole system.</p><div class="informalfigure"><div class="mediaobject"><img src="images/guac-menu-share-link.png" width="540" /></div></div><p>When the link is visited, that user will be given temporary access to your connection,
restricted according to the sharing option chosen. This access, and the validity of the
link overall, lasts only until you disconnect. Once the connection is closed, the link
ceases to be valid, and any users sharing the connection with you will be
disconnected.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="file-transfer"></a>Transferring files</h2></div></div></div><a id="idm46420847395568" class="indexterm"></a><p>You can transfer files back and forth between your local computer and the remote
desktop if it is supported by the underlying protocol and enabled on the connection.
Currently, Guacamole supports file transfer for VNC, RDP, and SSH, using either the
native file transfer support of the protocol or SFTP.</p><p>Files can be transferred to the remote computer by dragging and dropping the files
into your browser window, or through using the file browser located in the Guacamole
menu.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="file-browser"></a>Using the file browser</h3></div></div></div><p>If file transfer is enabled on the connection, you will see one or more filesystem
devices listed within the Guacamole menu. Clicking on one of the filesystems opens a
file browser which lists the files and directories within that filesystem.</p><div class="mediaobject"><img src="images/file-browser.png" width="270" /><div class="caption"><p>The file browser within the Guacamole menu.</p></div></div><p>Double-clicking on any directory will change the current location of the file
browser to that directory, updating the list of files shown as well as the
"breadcrumbs" at the top of the file browser. Clicking on any of the directory names
listed in the breadcrumbs will bring you back to that directory, and clicking on the
drive icon on the far left will bring you all the way back to the root level.</p><p>Downloads are initiated by double-clicking on any file shown, while uploads are
initiated by clicking the "Upload Files" button. Clicking "Upload Files" will open a
file browsing dialog where you can choose one or more files from your local
computer, ultimately uploading the selected files to the directory currently
displayed within the file browser.</p><p>The state of all file uploads can be observed within the notification dialog that
appears once an upload begins, and can be cleared once completed by clicking the
"Clear" button. Downloads are tracked through your browser's own download
notification system.</p><div class="mediaobject"><img src="images/file-transfers.png" width="270" /><div class="caption"><p>In-progress and completed file transfers.</p></div></div><p>When you are done browsing the filesystem and transferring files, click "Back" to
return to the Guacamole menu.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="rdp-virtual-drive"></a>The RDP virtual drive</h3></div></div></div><p>RDP provides its own native support for file transfer called "drive redirection"
or "RDPDR". Guacamole provides support for this mechanism by emulating a virtual
drive. Typically, this virtual drive will appear as a network drive within the RDP
session. Files uploaded and downloaded will be preserved within this drive, even
after disconnecting.</p><div class="mediaobject"><img src="images/guacamole-drive.png" width="450" /><div class="caption"><p>The Guacamole drive within a Windows RDP session.</p></div></div><p>Files can be downloaded from this drive using the file browser in the Guacamole
menu or using the special "Download" folder within the virtual drive. All files
dropped into this folder will automatically begin uploading to the client, and thus
downloading through the browser.</p><div class="mediaobject"><img src="images/guacamole-drive-download.png" width="450" /><div class="caption"><p>The Guacamole drive's "Download" folder.</p></div></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="guacctl"></a><span class="command"><strong>guacctl</strong></span> / <span class="command"><strong>guacget</strong></span></h3></div></div></div><p><a id="idm46420847371648" class="indexterm"></a><a id="idm46420847370784" class="indexterm"></a><a id="idm46420847369920" class="indexterm"></a><a id="idm46420847368608" class="indexterm"></a>In addition to traditional drag-and-drop and the file browser,
Guacamole's SSH support can be used with the <span class="command"><strong>guacctl</strong></span> utility. The
<span class="command"><strong>guacctl</strong></span> utility is a simple shell script <a class="link" href="https://raw.githubusercontent.com/apache/guacamole-server/master/bin/guacctl" target="_top">included with Guacamole</a> which allows you to use and configure file
transfer directly from the command line within the SSH session:</p><div class="informalexample"><pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>guacctl</code></strong>
<code class="computeroutput">guacctl 0.8.0, Guacamole SSH session control utility.
Usage: guacctl [OPTION] [FILE]...

<code class="prompt">$</code> <strong class="userinput"><code>guacctl -d <em class="replaceable"><code>FILENAME</code></em></code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>guacctl -s <em class="replaceable"><code>DIRECTORY</code></em></code></strong>
$</pre></div><p>For convenience, you may also create a symbolic link or alias to
<span class="command"><strong>guacctl</strong></span> called <span class="command"><strong>guacget</strong></span>. When run as
<span class="command"><strong>guacget</strong></span>, the utility behaves as if the
<code class="option">--download</code> option were supplied and initiates a download for
each file specified on the command line.</p></div></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="using-the-osk"></a>On-screen keyboard</h2></div></div></div><p>Certain key combinations are impossible to press within a web application like
Guacamole because they are reserved by the operating system (<span class="keycap"><strong>Ctrl</strong></span>+<span class="keycap"><strong>Alt</strong></span>+<span class="keycap"><strong>Del</strong></span> or <span class="keycap"><strong>Alt</strong></span>+<span class="keycap"><strong>Tab</strong></span>, for example) or by the web browser. If you press one of these reserved
combinations, the effect will be observed locally, not remotely, and the remote desktop
will receive only some of the keys.</p><p>Guacamole provides its own, built-in on-screen keyboard which allows keys to be sent
to the remote desktop without affecting the local system. If the device you're using
does not have certain keys which the remote desktop depends on, such as the arrow keys
or <span class="keycap"><strong>Ctrl</strong></span>, you can use the on-screen keyboard for this, too. You can show
the on-screen keyboard by selecting the "On-screen keyboard" option from the
menu.</p><p>Clicking (or tapping) the buttons of the on-screen keyboard has the same effect as
pressing the same buttons on a real keyboard, except that the operating system and
browser will not intercept these keypresses; they will only be sent to the remote
desktop.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="scaling-display"></a>Scaling the display</h2></div></div></div><p><a id="idm46420847771680" class="indexterm"></a>Guacamole will default to shrinking or expanding the remote display to fit
the browser window exactly, but this is not necessarily ideal. If the remote display is
much larger than your local display, the screen may be impossible to see or interact
with. This is especially true for mobile phones, whose screens need to be small enough
to fit in the average hand.</p><p>You can scale the display on touch devices by using the familiar pinch gesture. Place
two fingers on the screen and bring them closer together to zoom out or further apart to
zoom in.</p><p>If your device lacks a touch screen, you can also control the zoom level through the
menu. The controls for zooming in and out are located at the bottom of the menu. The
current zoom level is displayed between two "-" and "+" buttons which control the zoom
level in 10% increments.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="touch-devices"></a>Mobile or touch devices</h2></div></div></div><p>Guacamole is designed to work equally well across all HTML5 browsers, including those
of mobile devices. It will automatically handle input from a touch screen or a
traditional mouse (or both, if you happen to have such a gifted computer), and provides
alternative input methods for devices which lack a physical keyboard.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="touch-mouse"></a>Mouse emulation</h3></div></div></div><p><a id="idm46420847765920" class="indexterm"></a>In the case that your device has a touchscreen and lacks a mouse,
Guacamole will emulate a mouse for the sake of interacting with remote desktops that
expect mouse input. By default, Guacamole uses "absolute" mouse emulation. This
means that the mouse pointer is positioned at the location of each tap on the
screen.</p><p>In both absolute and relative modes, you can click-and-drag by tapping the screen
and then quickly placing your finger back down. This gesture only causes the mouse
button to press down, but does not release it again until you lift your finger back
up.</p><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="absolute-mouse-emulation"></a>Absolute mode (touchscreen)</h4></div></div></div><p>Absolute mouse emulation is the default as it tends to be what people expect
when using a touch device to interact with applications designed for mouse
input.</p><p>Each tap on the screen is translated into a left-click at that position.
Right-clicking is accomplished through pressing and holding your finger on the
screen. If parts of the remote display are off-screen, you can drag your finger
around the screen to pan the off-screen parts back into view.</p><p>Although absolute mouse emulation works generally well, a finger makes for a
very inaccurate pointing device. To address this, Guacamole also provides
"relative" mouse emulation. Relative mouse emulation provides a way to deal with
the need for accurate pointer control, when a true pointer device is not
present.</p><div class="informalfigure"><div class="mediaobject"><img src="images/touchscreen.png" width="135" /></div></div></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="relative-mouse-emulation"></a>Relative mode (touchpad)</h4></div></div></div><p>Guacamole's relative mouse emulation behaves similarly to the touchpad present
on most modern laptops. You drag your finger across the display to move the
mouse pointer, and tap the display to left-click. The pointer moves relative to
the motion of your finger. Right-clicking is accomplished with a two-finger tap,
and middle-clicking with a three-finger tap. The mouse scroll wheel can be
operated by dragging two fingers up or down.</p><p>Because the relative mouse emulation reserves so many gestures for the
different mouse buttons and actions, common touch gestures like panning and
pinch-to-zoom will not work while relative mouse emulation is enabled. Instead,
the screen will automatically pan to keep the mouse pointer in view, and you can
zoom through the buttons in the menu.</p><div class="informalfigure"><div class="mediaobject"><img src="images/touchpad.png" width="135" /></div></div></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="text-input"></a>Typing without a physical keyboard</h3></div></div></div><p>Many mobile devices lack a physical keyboard entirely, and instead provide their
own on-screen keyboards. As these are not true keyboards per se and do not produce
key presses, Guacamole's text input mode is required for typing on these
platforms.</p><p>"Text input" allows input of keystrokes based on the input of text. Choosing "Text
input" tells Guacamole to infer keystrokes by tracking text entered, rather than
relying on actual key presses. Guacamole will instead determine the combination of
keypresses necessary to produce the same pattern of input, including
deletions.</p><p><a id="idm46420847750064" class="indexterm"></a>If you wish to type via an IME (input method editor), such as those
required for Chinese, Japanese, or Korean, text input mode is required for this as
well. Such IMEs function through the explicit insertion of text and do not send
traditional key presses. Using text input mode within Guacamole thus allows you to
use a locally-installed IME, without requiring the IME to be installed on the remote
desktop.</p></div></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="preferences"></a>Changing preferences</h2></div></div></div><p>User preferences can be changed within the settings screen. These preferences are
stored locally within the browser, so if you use multiple computers to access Guacamole,
you can have different settings for each location. The settings screen allows users to
change the language of the Guacamole interface, to change the default input method used
by Guacamole connections, and to change the default mouse emulation mode for if a touch
device is used. If you have sufficient permissions, you may also change your password,
or administer the system.</p><div class="informalfigure"><div class="screenshot"><div class="mediaobject"><img src="images/guacamole-preferences.png" width="540" /><div class="caption"><p>Guacamole preferences screen.</p></div></div></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="display-language"></a>Display language</h3></div></div></div><p>The Guacamole interface is currently available in English, Dutch, French, German,
Italian, and Russian. By default, Guacamole will attempt to determine the
appropriate display language by checking the language preferences of the browser in
use. If this fails, or the browser is using a language not yet available within
Guacamole, English will be used as a fallback.</p><p>If you wish to override the current display language, you can do so by selecting a
different language within the "Display language" field. The change will take effect
immediately.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="changing-password"></a>Changing your password</h3></div></div></div><p>System administrators can restrict the ability of individual users to change their
own passwords, so this section may not always be available. If your account
<span class="emphasis"><em>does</em></span> have permission, the preferences screen will contain a
"Change Password" section.</p><p>To change your password, you must provide your current password, enter the desired
new password, and click "Update Password". You will remain logged in, and the change
will affect any future login attempt.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="default-input-settings"></a>Default input settings</h3></div></div></div><p>Guacamole provides multiple keyboard input methods and multiple mouse emulation
modes. Many of these settings are specifically useful for touch devices, while
others are aimed mainly at traditional desktop use. By default, Guacamole will use
the keyboard and mouse modes most commonly preferred by users, but you can change
these defaults if they do not fit your tastes or your current device.</p><p>The choices available mirror those within the Guacamole menu discussed earlier in
this chapter, and changing these settings will affect the default values selected
within the Guacamole menu of future connections.</p></div></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="adhoc-connections.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="users-guide.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="administration.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 14. Ad-hoc Connections </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 16. Administration</td></tr></table></div>
