Comment on [PSA] Watch for the antiyanks troll and consider adjusting your rate limits
Sal@mander.xyz 2 days agoThanks!
I was able to crash the instance for a few minutes, but I think I have a better idea of where the problem is. Ths $emote_addr variable seems to work just the same.
In the rate limit options there is a limit for ‘‘Message’’. Common sense tells me that this means ‘direct message’, but setting this to a low number is quite bad. While testing I eventually set it to ‘1 per minute’ and the instance became unresponsive until I modified the settings in the database manually. If I give a high number to this setting then I can adjust the other settings without problem.

“Message” bucket is kind of a general purpose bucket that covers a lot of different endpoints. I had to ask the lemmy devs what they were back when I was adding a config section in Tesseract for the rate limits.
These may be a little out of date, but I believe they’re still largely correct:

So, ultimately my problem was that I was trying to set all of the limits to what I thought were “reasonable” values simultaneously, and misunderstood what ‘Message’ meant, and so I ended up breaking things with my changes without the reason being obvious to me. I looked into the source code and I can see now that indeed ‘Messages’ refer to API calls and not direct messages, and that there is no ‘Direct Message’ rate limit.
If I let ‘Messages’ stay high I can adjust the other values to reasonable values and everything works fine.
Thanks a lot for your help!! I am surprised and happy it actually worked out and I understand a little more 😁

Hi I think I set the messages too low as well and now no.lastname.nz is down, pointers on how to fix with no frontend?

If you have DB access, the values are in the
local_site_rate_limittable. You’ll probably have to restart Lemmy’s API container to pick up any changes if you edit the values in the DB.Sal@mander.xyz 2 days ago
Sorry, I went to sleep. Glad you were able to sort it out 😄
