WebShell3 can be installed on any version of H-Sphere winbox. You need
to have PHP version 4.3.1 or higher. To ensure you have all required libraries,
install PHP from the zip archive, not self-extracting executable.
- Run the file from the command line. Once you see the message
"WebShell was installed successfully", you can access it from the control panel.
To uprade webshell on winbox, simply install the new version on top of the old one.
