So, whilst trying to get my server configured for email using the two similar recipes laid out here and here, I decided to do over, again. This time…
- I discovered a bug in Amazon Web Services, or an easy to misconfigure option. I firewall blocked ports 80 and 443, the two ports necessary to host a website.
- I found a way to introduce files in to nextcloud without having to upload again (put them in place, set the owner and permissions, run a command).
- I opened my mail ports to the world early in my set up of the mail server and, half way through, when I was encouraged to go through log files, I saw page upon page of failed log in attempts from hackers. I closed the ports and I believe they continued, which is why I reloaded again.
Bring on the paranoia!
Oh well.
