I am looking at this Q&A: How to open a port?.
The question title is about opening ports in general. The question "body" and the answer focus on port 25 and how to list open ports, but do not address the title question in general.
I keep coming back to this thread whenever i forget the command on how to open a port on a raspberry/debian, but do not find the desired answer even though the title indicates so. And with 61k views i suppose there might be others whose interest is not restricted to port 25.
There might be two solutions:
- modifying the question title (+ open new question?)
- place a second answer on how to open ports in general
I initially went for an answer: https://raspberrypi.stackexchange.com/a/111330/115531. But then i thought i better ask here on meta.
Modifying the title would have the advantage to have a cleaner question - answer fit. Downside would be that user searching for that question ("How to open port?") would still not get an answer that fast.
The question seems to be very easy to find via search engines (60k+ views). One could open another question + answer, to address the general question on how to open a port and hope it will become one of the top results?
