Setup di Discourse: presuppone che nc sia installato

Contribuisci Bug

Ran through the install using discourse-setup (I don’t think I ever have yet, so no time like the present!) and the following error showed up:

Checking your domain name . . .
WARNING:: This server does not appear to be accessible at dotest.example.net:443.

A connection to http://dotest.example.net (port 80) also fails.

This suggests that dotest.example.net resolves to the wrong IP address
or that traffic is not being routed to your server.

Google: "open ports YOUR CLOUD SERVICE" for information for resolving this problem.

You should probably answer "n" at the next prompt and disable Let's Encrypt.

This test might not work for all situations,
so if you can access Discourse at http://dotest.example.net, you might try anyway.

I believe this happened as nc isn’t installed so it couldn’t properly run the test. We should ensure nc is available before erroring out on this check.

I totally believe that I assumed that nc was installed and that on some OSs it’s not.

The messages do suggest that it could be wrong. Did Let’s Encrypt work?

What OS is this? What cloud service?

Fresh debian-9 on DO.

Everything else worked A-OK and it’s up and running great! :+1:

Hmm. Then the question becomes, does discourse-doctor install nc just for one test that might not be necessary, or just say, “well, you don’t have nc, so you’re on your own to see that you have ports open and mapped correctly.”?

I don’t like installing software if it’s not necessary. I think I’ll change the message to recommend installing nc if they want it.

@codinghorror? @mpalmer want to weigh in?

Wasn’t this addressed in a different way by @supermathie?

I’m all for this :+1:

I addressed the problem where Discourse’s email test rake task didn’t properly pick up the STARTTLS option. This is separate.

In that case either stop the script and tell them to re-run with nc installed, or print a warning that the check was skipped because nc was not installed?

I was going to let the script continue with the warning, adding the bit about nc. As it is, it does work, it just suggests that it probably won’t.

Possiamo chiuderla come risolta, @pfaffman?

Beh, sono passati 6 mesi. Non ho aggiunto un messaggio del tipo “non hai nc, quindi non posso testare le tue porte”, ma nessuno si è lamentato. Forse il linguaggio:

     Google: "open ports YOUR CLOUD SERVICE" per informazioni su come risolvere questo problema.
    
     Dovresti probabilmente rispondere "n" al prossimo prompt e disabilitare Let's Encrypt.
    
     Questo test potrebbe non funzionare in tutte le situazioni,
     quindi se riesci ad accedere a Discourse all'indirizzo http://$HOST, potresti provare lo stesso.

è sufficiente. Non è mai stato un :bug:, ma piuttosto un fastidio per chi aveva abbastanza competenza da amministratore di sistema da non voler usare Ubuntu. Funziona come previsto su Ubuntu (non ho controllato altre distribuzioni). Sono incline a non toccare questa faccenda.
