Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
    • 5. ๐Ÿ‡ฌ๐Ÿ‡ง Language/ัะทั‹ะบ/Sprache
  • This is primarily an English-speaking community. ๐Ÿ‡ฌ๐Ÿ‡ง๐Ÿ‡ฆ๐Ÿ‡บ๐Ÿ‡บ๐Ÿ‡ธ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
    • ย 

    Please report posts and comments that break these rules!

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

    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.

    The TLDR is here : https://www.digitalocean.com/community/tutorials/recommended-security-measures-to-protect-your-servers

    You wonโ€™t be protected from a dedicated, knowledgeable attacker until you do the rest of what the other poster said, and then some,

    You're right I didn't even get to ACME and PKI or TOTP
