It is very easy to set up WebShell.
First you need to make sure python 2.3 or later and OpenSSL are installed on your system. You will also have to install the pyOpenSSL python extensions to OpenSSL.
Next you need to generate a server certificate. From the WebShell directory enter this command to quickly generate a certificate:
./make_certificate.sh
Now issue this command to run the server:
./webshell.py
To make sure that everything went well, check this URL in your browser: https://127.0.0.1:8022
You can change WebShell's background by overwriting the background.jpg file. You can also change the display colors in webshell.css. Restart the server afterwards to make your changes effective.
Voilà, enjoy WebShell.
