1. Find a way to start a simple HTTP server inside Pwnbox or your local VM using “npm”. Submit the command that starts the web server on port 8080 (use the short argument to specify the port number).

First of all, npm is a package manager of NodeJS. When you click on the hint (HTB Academy) it says:

In short, it is not required to install npm in this case (it assumes that it is already installed). Or if not use the command:

sudo apt install node-http-server

Once installed, check it’s manual page, then run the command and specify the port with -p flag.

Answer: http-server -p 8080

2. Find a way to start a simple HTTP server inside Pwnbox or your local VM using “php”. Submit the command that starts the web server on the localhost (127.0.0.1) on port 8080.

We can see the manual page, of php.

According to this manual page, we can start a webserver with syntax php -S addr:port.

So the required IP and port is 127.0.0.1 and port is 8080.

Answer: php -S 127.0.0.1:8080
