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 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 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

--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 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".

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¶

"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 seperate the lines), for verification purposes.

"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)

"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.

For example, to tunnel connection through foobar host HTTP proxy on port 8080, use the value "http://foobar:8080".

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
