leash: A Browser-Based Shell Solution

leash is a web application designed to provide users with shell access without the need for root privileges, SSH, or Telnet, leveraging only PHP-based hosting. This tool empowers users by allowing shell command execution through simple PHP server configurations, making it an accessible solution for web developers and system administrators alike.

Key Features

• Multiple Command Support: Execute various commands, including MySQL and SQLite commands, enhancing database interactions directly from the browser.
• Interpreters: Access a Python interpreter and a JavaScript interpreter, allowing dynamic script execution within the web environment.
• Jargon and Document Access: Utilize the jargon command to fetch definitions from a jargon file, and leverage RFC commands to read relevant RFC documents
• Editing Tools: Use the ymacs editor and vi editor to manage code and text efficiently, supporting familiarity for users accustomed to traditional command-line editors.
• Advanced Functionality:
  • Tab Completion: Streamline command inputs with intelligent tab completion.
  • File Upload: Drag and drop files with HTML5 capability, enabling uploads that exceed the typical PHP limits.
  • Interactive Views: View HTML pages as plaintext in the terminal, facilitating content browsing directly within the shell environment.
• Session Management: Record commands in a hash for easy reruns after refreshing.
• Repository Browsing: Browse GitHub repositories with basic command support for file manipulation.
• User Access Control: Configure guest and sudo options for varied access levels, enhancing security and user management.

System Requirements

• Requires PHP version 5.5 or higher with enabled modules: curl, mbstring, json, and zip.
• To fully leverage leash’s capabilities, ensure the availability of one of the following functions: exec, system, shell_exec, or CGI with Perl/Python.
• For database commands, appropriate MySQL or SQLite installations and PHP modules are necessary.
• Optional installation of the programm unbuffer will enhance non-interactive shell experiences to simulate a real terminal.
