remote-viewer – a simple remote desktop client


remote-viewer [OPTIONS] — [URI]


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 FILE section
for a description of the format.


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 at
best the client physical monitor configuration on initialization,
by enabling or disabling extra monitors as necessary. This is
currently implemented by the Spice backend only.

-t TITLE, –title TITLE
Set the window title to TITLE

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.

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
=[+][,=[+]]. 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:



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.

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.

A key binding combination is described by a series of key strings
seperated 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”.

remote-viewer connection file is of INI file format, with a mandatory
[virt-viewer] group and “type” key.

Opening a file with the following content will start remote-viewer in
fullscreen and connect to the host “betsiboka” using the SPICE

[virt-viewer] type=spice

“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

Use -1 for class/vendor/product/version to accept any value.

And the rules themselves are concatenated like this:
