nc: command not found

# Description

Seeing this error: /bin/bash: line 1: nc: command not found

# Technical Information

Netstat needs to be install.

Can be done in the Dockerfile like this:

RUN apt install -y netcat

I don't see a Dockerfile in the codebase.

Check how the sandbox is started and whether a Dockerfile or other container setup exists. Reproduce the `/bin/bash: line 1: nc: command not found` error, then verify that the relevant environment provides the `nc` command and that the original command runs successfully.
