A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

History shows command I didn't run on my VPS (lemmy.ml)

Hey guys, I saw this in my VPS when checking history:

    1  chmod +x /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
    2  cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
    3  vi /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f

here is the content of the script:

# cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
swapoff /dev/vda2;mkswap /dev/vda2;swapon /dev/vda2;resize2fs /dev/vda1;yum -y update;systemctl disable guestfs-firstboot;reboot

This is a new server I provisioned on my VPS in racknerd. The command looks safe, but I'm wondering if these commands were executed on its own? Or someone has logged in to my VPS? This is also not normal, isn't it?

EDIT:

confirmed, commands are still in history after reinstalling OS. As others have said, maybe the image builder ran commands and forgot to clear history
