    change ssh port without realizing iptables is set to block every port except 22, 80 and 443, on a dedicated server without ipmi.

    Second biggest: install ubuntu on a server

    Couple of weeks ago, I was setting up couple of new nodes. After setting everything up, I have realized that I got right OS on the wrong server and the right server got wrong reload. From that day, Only 1 kvm session per monitor.

    @dmmcintyre3 said: change ssh port

    I never understood that move... I mean, random bots trying random passwords will never break a real pass. If they are on you, changing ssh port wouldnt matter, they will find it, unless you allow only certain hosts, and if you do that, why would you change the port in the first place, etc.
    IMO, that move is not necessary, at least it does more harm than good.

  • @maounique it allows you to detect port scans and block it, instead of letting them get past the first, easy hurdle.

  • MaouniqueMaounique Host Rep, Veteran

    If we are to got hat far... Key only and it is solved. Or block all except your ip. Preferably the IP of some VPS you have.
    It is enough I have to remember 100 passes, remembering ports too would be too much...
    But I guess to each his own :)

    @Maounique who needs to memorize when you have Excel?

    Believe me, I have 10+ tabs in each browser, 3 browsers open, 10 terminals, I certainly dont need another browser tab :)
    Not to mention when I am away with my crappy laptop.

    Confusing my local shell with my remote shell, and accidentally wiping /var/www on a production server instead of my local development stack.

    I was really happy that I'm paranoid about backups, at that moment.

    Sounds like you guys need a molly-guard. sudo apt-get install molly-guard should just about do it it, I think.

    @Maounique think you got it rough?

    My whole system is begging for mercy.

  • The worst thing I did was chown www-data:www-data in /var instead of /var/www

    For some reason nothing worked correctly after that

  • years ago

    UPDATE tbl_userfunctions SET myfunction ="function(){......code ... code .. code}"

    without WHERE id_function -

    auto commit and good night

  • Solus reinstall on wrong server (not the test one, but one in use) was nice. No fuckups unless a beer/glass red wine or 5 tho..

  • Shutdown a production server instead of the local dev system. Worse, it was an AWS instance with local storage only, so once it shutdown, EC2 deleted the hard disk. Fortunately, databases were on a different instance, but a couple of very stressful hours to get all the apps and config re-installed!

  • Many years ago I made the mistake of getting 2 SSH connections open and RM'd the wrong /home/xxx directory.

    along with no backups!

    Certainly have learnt from that mistake, atleast it was my own box :)

  • Installing fedora on it.

    Never again.

    It will come a time, my friend, no worries... :)

    3 old ladies were talking about memory loss that comes with age:

    • I am forgetting a lot, my dears, yesterday I forgot the cat locked in the balcony for the whole day...
    • That is nothing, I forgot the refrigerator door open for the whole day...
    • Knock on wood, I never had such problems, says the third while she keeps knocking. After a while:
    • Hey, dont you hear that knocking ? Maybe there is someone at the door !

  • Didn't make any backups, then I reinstalled the OS. I was supposed to do it with another VPS but meh, fail.

    I will try not to haha

  • a bit off-topic, but the mistake I recall is to have bought VPS for 1 year, and to finally conclude after 2 months that there are low end VPS which outperform my costly full-year VPS, and is about 3 times cheaper. I did only use the VPS for backup purpose. Since that time, I've fallen in love with LEB/LET and will trust only price + remarks and appraisals of LEB/LET members.
