NAME
remote-viewer - a simple remote desktop client
SYNOPSIS
remote-viewer [OPTIONS] -- [URI]
DESCRIPTION
remote-viewer is a simple remote display client. The supported protocols are SPICE and VNC.
Starting remote-viewer without URI will open a simple dialog with an entry and a list of previously
successfully accessed URI.
The URI can also point to a connection settings file, see the CONNECTION FILE section for a description
of the format.
OPTIONS
The following options are accepted when running "remote-viewer":
-h, --help
Display command line help summary
-V, --version
Display program version number
-v, --verbose
Display information about the connection
-z PCT, --zoom=PCT
Zoom level of the display window in percentage. Range 10-400.
-f, --full-screen
Start with the windows maximized to fullscreen.
If supported, the remote display will be reconfigured to match the physical client monitor
configuration, by enabling or disabling extra monitors as necessary. This is currently implemented by
the Spice backend only.
To specify which client monitors are used in fullscreen mode, see the CONFIGURATION section below.
-t TITLE, --title TITLE
Set the window title to TITLE
--spice-controller
Use the SPICE controller to initialize the connection with the SPICE server. This option is used by
the SPICE browser addons to allow web page to start a client.
--debug
Print debugging information
-H HOTKEYS, --hotkeys HOTKEYS
Set global hotkey bindings. By default, keyboard shortcuts only work when the guest display widget
does not have focus. Any actions specified in HOTKEYS will be effective even when the guest display
widget has input focus. The format for HOTKEYS is
<action1>=<key1>[+<key2>][,<action2>=<key3>[+<key4>]]. Key-names are case-insensitive. Valid actions
are: toggle-fullscreen, release-cursor, secure-attention, smartcard-insert and smartcard-remove. The
"secure-attention" action sends a secure attention sequence (Ctrl+Alt+Del) to the guest. Examples:
--hotkeys=toggle-fullscreen=shift+f11,release-cursor=shift+f12
--hotkeys=release-cursor=ctrl+alt
Note that hotkeys for which no binding is given are disabled. Although the hotkeys specified here are
handled by the client, it is still possible to send these key combinations to the guest via a menu
item.
-k, --kiosk
Start in kiosk mode. In this mode, the application will start in fullscreen with minimal UI. It will
prevent the user from quitting or performing any interaction outside of usage of the remote desktop
session.
Note that it can't offer a complete secure solution by itself. Your kiosk system must have additional
configuration and security settings to lock down the OS. In particular, you must configure or disable
the window manager, limit the session capabilities, use some restart/watchdog mechanism, disable VT
switching etc.
--kiosk-quit <never|on-disconnect>
By default, when kiosk mode is enabled, virt-viewer will remain open when the connection to the
remote server is terminated. By setting kiosk-quit option to "on-disconnect" value, virt-viewer will
quit instead.
HOTKEY
A key binding combination is described by a series of key strings separated by '+' that must be pressed
together in order to activate the associated action.
It must be composed of modifiers (shift, ctrl or alt) and a non-modifier key. For example, "shift+f11".
CONNECTION FILE
remote-viewer connection file is of INI file format, with a mandatory [virt-viewer] group and "type" key.
Example
Opening a file with the following content will start remote-viewer in fullscreen and connect to the host
"betsiboka" using the SPICE protocol:
[virt-viewer]
type=spice
host=betsiboka
port=5900
fullscreen=1
Key list
"version" (string)
If remote-viewer version number isn't greater or equal to the required version, an error is raised
with the expected version.
The version format accepted is a list of integers separated by '.'. It can be followed by a dash '-'
and an additional build number with the same format.
Version comparison is done by comparing each integer from the list one by one. If any of the
component is not a number, the version comparison will fail and consider that the 2 versions are
considered to be the same.
"versions" (osid:version list)
This is a list of osid:version couples separated by ';'. osid is an arbitrary string, version is a
version number in the same format as in the 'version' field. A given couple indicates that remote-
viewer builds matching the given 'osid' (fedora22, debian7, ...) must be at least version 'version'.
For consistency, it's recommended to use libosinfo OS shortids as the osid.
"newer-version-url" (string)
If specified, this field is an URL which will be displayed to the user when a version check fails.
"type" (string, mandatory)
The session type, either "spice", "vnc" or "ovirt".
"host" (string, mandatory)
The server host to connect to.
"port" (integer)
The server port to connect to.
"tls-port" (integer)
The server TLS/SSL port to connect to.
"username" (string)
The username for the session authentication.
"password" (string)
The password for the session authentication.
"disable-channels" (string list)
The list of session channels to disable.
The current SPICE channels are: main, display, inputs, cursor, playback, record, smartcard, usbredir.
"tls-ciphers" (string)
Set the cipher list to use for the secure connection, in textual OpenSSL cipher list format. (see
ciphers(1))
"title" (string)
String to present in the window title.
"fullscreen" (boolean)
Opens the client windows in fullscreen.
"ca" (string)
CA certificate in PEM format (using "\n" to separate the lines). This will be used to verify the SSL
certificate used for SPICE TLS sessions.
"host-subject" (string)
Verify the certificate subject matches with the given subject.
"toggle-fullscreen" (hotkey string)
Key binding for entering and leaving fullscreen mode. (see HOTKEY for description of expected string)
"release-cursor" (hotkey string)
Key binding for releasing cursor grab. (see HOTKEY for description of expected string)
"smartcard-insert" (hotkey string)
Key binding for inserting emulated smartcard. (see HOTKEY for description of expected string)
"smartcard-remove" (hotkey string)
Key binding for removing emulated smartcard. (see HOTKEY for description of expected string)
"color-depth" (integer)
Set the color depth of the guest display (16 or 32).
"disable-effects" (string list)
A list of desktop effects to disable in the remote guest.
The effects that can be disabled with SPICE are: wallpaper, font-smooth, animation or all.
"enable-smartcard" (boolean)
Set to 1 to enable client smartcard redirection.
"enable-usbredir" (boolean)
Set to 1 to enable client USB device redirection.
"enable-usb-autoshare" (boolean)
Set to 1 to enable client USB devices auto-sharing.
"usb-filter" (string)
Set a string specifying a filter to use to determine which USB devices to autoconnect when plugged
in, a filter consists of one or more rules. Where each rule has the form of:
"class,vendor,product,version,allow"
Use -1 for class/vendor/product/version to accept any value.
And the rules themselves are concatenated like this:
"rule1|rule2|rule3"
"secure-channels" (string list)
The list of session channels to secure.
The current SPICE channels are: main, display, inputs, cursor, playback, record, smartcard, usbredir.
"delete-this-file" (boolean)
Set to 1 for the client to remove this connection file (if it can't, it will fail silently)
"proxy" (string)
A proxy URL to tunnel the connection through.
At the time of writing this documentation, the only supported proxy method with Spice is HTTP
CONNECT.
For example, to tunnel connection through foobar host HTTP proxy on port 8080, use the value
"http://foobar:8080".
oVirt Support
The connection file can also carry some oVirt-specific options when oVirt support is compiled in. These
options are used to interact with oVirt REST API. This is currently only used in order to show a menu
allowing to change the CD image being used by the virtual machine from remote-viewer user interface.
These options go in an optional [ovirt] group.
"host" (string, mandatory)
The oVirt instance to connect to. This corresponds to the hostname one would connect to access the
oVirt user or admin portal.
"vm-guid" (string, mandatory)
GUID of the oVirt virtual machine to connect to.
"jsessionid" (string)
Value to set the 'jsessionid' cookie to. With oVirt 3.6, setting this authentication cookie to a
valid value will allow to interact with the oVirt REST API without being asked for credentials.
"sso-token" (string)
Value to set the 'Authorization' header to. With oVirt 4.0 or newer, setting this authentication
header to a valid value will allow to interact with the oVirt REST API without being asked for
credentials.
"ca" (string)
CA certificate in PEM format (using "\n" to separate the lines). This will be used to validate the
certificate used for the oVirt REST https session remote-viewer will establish.
CONFIGURATION
A small number of configuration options can be controlled by editing the settings file located in the
user configuration directory:
<USER-CONFIG-DIR>/virt-viewer/settings
This file is a text file in INI format, with application options in the [virt-viewer] group and per-guest
options in a group identified by the guest's UUID. The application options should not be edited manually.
There is also a special [fallback] group which specifies options for all guests that don't have an
explicit group.
For each guest, the initial fullscreen monitor configuration can be specified by using the monitor-
mapping key. This configuration only takes effect when the -f/--full-screen option is specified.
The value of this key is a list of mappings between a guest display and a client monitor. Each mapping is
separated by a semicolon character, and the mappings have the format
<GUEST-DISPLAY-ID>:<CLIENT-MONITOR-ID>.
For example, to map guest displays 1 and 2 to client monitors 2 and 3 for the guest with a UUID of
e4591275-d9d3-4a44-a18b-ef2fbc8ac3e2, use:
[e4591275-d9d3-4a44-a18b-ef2fbc8ac3e2]
monitor-mapping=1:2;2:3
The monitor-mapping must contain ids of all displays from 1 to the last desired display id, e.g.
"monitor-mapping=3:3" is invalid because mappings for displays 1 and 2 are not specified.
EXAMPLES
To connect to SPICE server on host "makai" with port 5900
remote-viewer spice://makai:5900
To connect to VNC server on host "tsingy" with port 5900
remote-viewer vnc://tsingy:5900
To connect to a virtual machine named "toliara" on an oVirt server at example.org
remote-viewer ovirt://[username@]example.org/toliara
