Background: 15 years of experience in software and apparently spoiled because it was already set up correctly.
Been practicing doing my own servers, published a test site and 24 hours later, root was compromised.
Rolled back to the backup before I made it public and now I have a security checklist.
Why would a Swedish ISP care? I’ve run servers from home since I first connected up in … 1996. I’ve had a lot of different ISPs during that time, although nowadays I always choose Bahnhof because of them fighting the good fights.
They probably don’t, unless I got compromised and bad traffic came from their network, but I was paranoid, and wanted to avoid the possibility.
