Is there a way to Integrate IP Ban into Minecraft Server logs ?

[sakura-ryoko]

Hello,
I have a Minecraft Server, and I would like to add it's log files to an available list for IP's to Ban for failed login attempts.

Has anyone done this successfully yet?

Thanks.

I looked in my server logs and I don't see any IP info....

This is an example of the Minecraft log file from my system

[2024-05-04 16:01:41] [2024-05-04 16:01:41:290 INFO] Player Spawned: da99Beast xuid: 253############9, pfid: dd77$$$$$$$$$$b9

Do you have IP info in one of your log files?

Yes, I removed the username and replaced it with "***"

Ahh...You are running the Java version, I am running Bedrock Edition.
