Selfhosted

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.

There have been users spamming CSAM content in [email protected] causing it to federate to other instances. If your instance is subscribed to this community, you should take action to rectify it immediately. I recommend performing a hard delete via command line on the server.

I deleted every image from the past 24 hours personally, using the following command: sudo find /srv/lemmy/example.com/volumes/pictrs/files -type f -ctime -1 -exec shred {} \;

Note: Your local jurisdiction may impose a duty to report or other obligations. Check with these, but always prioritize ensuring that the content does not continue to be served.

Update

Apparently the Lemmy Shitpost community is shut down as of now.

If the source deletes the post. Won’t that remove it from all the instances ?

I'm not subscribed to that community, but I guess I'm glad Pictrs doesn't work for me, since I am using the Yunohost version of Lemmy. The creators of the Yunohost package couldn't get it to work. I haven't really missed it honestly.

Can you run lemmy without pictrs? What behavior is different?

Could someone please ELI5 that script. I'm all for keeping things clean, but old enough to remember the days of console based trolling.

Looks fairly sane, finds every file in the given directory that was created in the last 24 hours and deletes them. Personally if you are dealing with CSAM I'd be using shred instead of just rm

sudo

As root

find /srv/lemmy/example.com/volumes/pictrs/files

Find files in /srv/lemmy... that:

-type f

Are plain files (not directories, symlinks, etc; includes images)

-ctime -1

And were created within an amount of time (probably last day, haven't used this flag in a while)

-exec rm {} \\;

For each matching file found execute rm on it (delete it).

sudo find /srv/lemmy/example.com/volumes/pictrs/files -type f -ctime -1 -exec rm {} \;

  • sudo: run as root
  • find /srv/lemmy/example.com/volumes/pictrs/files -type f: find files (f) in directory
  • -ctime -1: which have been created in the last day
  • -exec rm {} ; execute the command rm (remove) on each of them

I am using the Lemmy easy deploy would this command works?

[–] [email protected] 8 points 1 year ago

You'll need to find where the actual container files are being stored. I'm unfortunately not familiar with Lemmy Easy Deploy, but you should have a folder that has some files/folders like docker-compose.yml, volumes, lemmy.hjson.

The important one is the volumes/pictrs/files folder, take the full path of that folder and replace it with the /srv/lemmy/example.com... path from the original post, and then that command should work.

There was a weird JSON error I was getting in the last few minutes. I'm not sure if this is at all related.
