This is the command remote-viewer that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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

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
