feat(WIP): Try noports wish application

[XavierChanth]

- What I did

• Created a TUI bubbletea application to be served over SSH
• Allows to run 3 commands:
  • Display a welcome message
  • Run ip addr / ifconfig (-f flag to use ifconfig instead of ip addr)
  • Run nmap to scan all ports for the given host passed in (-h flag)

Update (June 13th, 2024): This was blocked by the C daemon, so we could statically link it into the go program. This is now ready to move forward, but I (@XavierChanth) don't currently have the bandwidth to continue working on it.

- How to verify it

Forgot to finish the welcome message, I will also explain all this code in the files changed tab before EOD

@XavierChanth how do I run this? I've already tried the obvious go get && go run main.go but that just gets me:

# command-line-arguments
./main.go:59:4: undefined: AppMiddleware

What's your thinking on tests? And how we're going to host this?

I've written the main package across multiple files, so you have to run via go run .

I'm not sure what to do about tests yet, most of the functions should be pure enough to unit test, and I think I could emulate some end2end tests. For the time being, I was thinking I setup a trial container to test against, and give the team access for testing and feedback. Ideally we release this with the APKAM installer, so I'm about on track.

Also, when I write the tests I can refactor the other files so that they are different, isolated packages and that way running go run main.go will work as expected.

Started dockerizing, this file explains how the usage is intended: https://github.com/atsign-foundation/noports/blob/try-noports-wish/packages/go/trynoports/docker.md

I designed the go application to spawn a go routine which runs sshnpd as a child process. This works fine, but SRV seems to crash... I think it has trouble binding sockets (see logs below)

FYI. The only dart:io classes used in srv are Process, Socket, InternetAddress.

At the moment the application crashes with:

The stuff indented under Msg= are the logs from sshnpd, which are relogged through the go program's logger.

This should be progressable at this point, but we don't have as much demand for it compared to the amount of effort it would be to embed the C version of sshnpd into this program. Closing for now
