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.
  • 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, no politics, no trolling or ragebaiting.
  • 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. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • 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.
  • 6. (NEW!) Regarding public figuresWe all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
  • Keep discussions polite and free of disparagement.
  • We are never in possession of all of the facts. Defamatory comments will not be tolerated.
  • Discussions that get too heated will be locked and offending comments removed.
  • Β 

    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.

    Best ping is 127.0.0.1

    It always resolves!

    [–] possiblylinux127@lemmy.zip 13 points 18 hours ago (1 children)

    Fun fact 127.0.0.1-127.255.255.254 is all localhost

    [–] Randelung@lemmy.world 7 points 6 hours ago* (last edited 6 hours ago) (2 children)

    Pretty insane that around 0.4% of all IPv4 addresses are wasted.

    [–] MystikIncarnate@lemmy.ca 4 points 3 hours ago

    Wayyyyyy more than that is wasted.

    Apple (and others) used to have an A class. I think they gave some of it back to the pool.

    Try pinging 127.1 - it is the same, but shorter.

    Just another tipp from someone who learned TCP/IP from reading the sources over three decades ago...

    [–] dwt@feddit.org 2 points 10 hours ago (1 children)

    That resolves to 0.0.0.0 - rarely useful

    [–] Hawke@lemmy.world 2 points 3 hours ago

    But it’s shorter!

    [–] shalafi@lemmy.world 10 points 22 hours ago (1 children)
    [–] Treczoks@lemmy.world 2 points 17 hours ago

    It's all in the documentation. But people don't read anymore.

    [–] DahGangalang@infosec.pub 1 points 16 hours ago* (last edited 16 hours ago)

    Can you explain how/why its the same?

    My instinct says its actually trying to reach 127.1.0.0 (which is still local host), but that's an educated guess at best.
