Description

For some reasons, I wanted to share my computer screen to other computers in the same local network (LAN or WLAN). I could not find an easy way to do it. So, I created this small screen sharing tool in Python.

In short, the computer to share screen runs this Python script that captures screenshots periodically and hosts screenshots as a web service. Other computers then browse the screenshots with any web browser.

Requirements (what I have in my own computer)

• Fedora 26 + Gnome3 running on Xorg

• Python 2.7

• Know issue: This tool does not work with Wayland because of a security reason. You must use Xorg (by selecting Xorg on login).

Installation and Run

1. pip install Flask-Bootstrap pyscreenshot

2. In a directory, run "git clone https://gitlab.com/qijungu/screenshare.git". You will have a new directory "screenshare" with code inside.

3. The command to run is "python screenshare.py [port]". Default port is 18331. Example commands are below.

   # host screenshots on port 18331
   python screenshare.py

   # host screenshots on port 80
   python screenshare.py 80

4. On other computers, open a web browser and browse "http://serverip:port".

   For example, if the server ip is 192.168.0.101 and the service port is 18331, then the URL to browse is "http://192.168.0.101:18331".
