GoRESTCmd

GoRESTCmd is a straightforward web application that enables remote execution of shell commands through HTTP API requests. This web service offers multiple API endpoints for executing, monitoring the status, and retrieving output from executed commands.

Features

• Execute shell commands remotely via HTTP API
• Retrieve the command output (stdout and stderr)
• Check the status of executed commands
• Limit concurrent command executions
• API key authentication

Configuration

Create a config.json file in the root of the project with the following contents:

api_key: "your-api-key",
concurrent_limit: 5,
port: 8080,
server_tls: false
server_cert_path: server.cert
server_key_path: server.key
allowed_commands: ["echo", "ping", "ls", "mkdir"]

Replace your-api-key with the actual API key you want to use. You can also adjust the concurrent_limit and port settings.
