AsyncVNC: Asynchronous VNC for Python

AsyncVNC is a Python package which provides an asynchronous client implementation of the VNC (RFB) protocol on top of
the asyncio framework.
.. code-block::
import asyncio, asyncvnc
async def run_client():
with asyncvnc.connect('localhost', 5900, 'username', 'password') as client:
client.keyboard.write('hello world!')
asyncio.run(run_client())
Features
--------
- Full support for keyboard, mouse, video and clipboard updates.
* The frame buffer can be exported as an RGBA numpy array.
* Keyboard keys are specified by name or character.
- Compatibility with traditional VNC servers (RealVNC, TightVNC, TigerVNC, etc).
* Including unauthenticated connections.
* Including password authentication with Triple DES.
- Compatibility with the built-in macOS Remote Desktop server.
* Including username/password authentication with 2048-bit RSA keys and 128-bit AES.
* Connects to the desktop, not the login screen.
- Detection of multi-head frame buffer data using a novel algorithm.
- Support for tunneling VNC over SSH with AsyncSSH.
- Support for image data compression with zlib.
Installation
------------
This package requires Python 3.7+.
Install AsyncVNC by running::
pip install asyncvnc
Connecting to a server
----------------------
This snippet connects to a local unauthenticated VNC server, prints information, and disconnects::
import asyncio, asyncvnc
async def run_client():
async with asyncvnc.connect('localhost') as client:
print(client)
asyncio.run(run_client())
To log in to a macOS server, supply *username* and *password* arguments::
async with asyncvnc.connect('localhost', username='user123', password='h4x0r'):
...
For traditional authenticated VNC servers, the *password* argument is required but not *username*.
.. warning::
Traditional VNC authentication is woefully insecure. For best results, configure your VNC server to listen only on
``127.0.0.1``. If you need external access, use an SSH tunnel.
To tunnel VNC over SSH, use the AsyncSSH package (after which this package is modelled)::
import asyncio, asyncssh, asyncvnc
async def run_client():
async with asyncssh.connect('myserver') as conn:
async with asyncvnc.connect('localhost', opener=conn.open_connection) as client:
print(client)
asyncio.run(run_client())
Sending events
--------------
Keyboard and mouse objects provide context managers for holding down keys and buttons::
with client.keyboard.hold('Ctrl'):
...
with client.mouse.hold():
...
The keyboard has methods for pressing keys and writing text::
client.keyboard.press('Ctrl', 'c') # keys are stacked
client.keyboard.write('hi there!') # keys are queued
The mouse has methods for moving the cursor and clicking::
client.mouse.move(100, 200)
client.mouse.click()
client.mouse.right_click()
client.mouse.scroll_up()
Taking a screenshot
-------------------
To retrieve an image from the VNC server and save it as a PNG file::
import asyncio, asyncvnc
from PIL import Image
async def run_client():
async with asyncvnc.connect('localhost') as client:
# Retrieve pixels as a 3D numpy array
pixels = await client.screenshot()
# Save as PNG using PIL/pillow
image = Image.fromarray(pixels)
image.save('screenshot.png')
asyncio.run(run_client())
The macOS VNC server composites attached monitors/screens into a single frame buffer. It does not send updates for
unoccupied regions; we can use this information to detect screens::
pixels = client.video.as_rgba()
for screen in client.video.detect_screens():
screen_pixels = pixels[screen.slices]
