Sneaky Server
by adryd
Sneaky Server is a server-side Fabric and Quilt management mod that hides server details from internet scanners and limits connection spam.
What it does
When a scanner such as Copenheimer ServerSeeker, Shodan or similar tools queries the server, Sneaky Server anonymises the response, so the server appears only with information about players who have previously joined. Server owners can turn on options that stop unauthorised players from seeing the server ping data, and a true setting sends the ping data only to known players, while a false setting sends it to unknown players but omits the user list.
Other options protect the server further. Logging of failed offline-mode logins can be disabled, and so can logs for clients that close a connection or for the server closing one. A rate limit allows clients to create new connections only up to a set count over a window, with a default of 7 connections over 15 seconds, and connections beyond that limit are closed. Legacy ping for very old clients can be disabled, and connections from banned IPs can be closed before they reach login logic.
The mod runs on the server only, so players join without installing anything. It is published for Fabric and Quilt across 13 release versions, 1.19.4 – 1.21.10, and is open source under the MIT License. Snapshot builds are also published. It is incompatible with BungeeCord and Velocity.
Key features
Anonymised server ping
Responses to server scanners show only information about players who have previously joined the server.
Logging controls
Logs of failed offline-mode logins and of closed connections can each be switched off in the config.
Connection rate limit
A configurable limit on new connections per time window closes connections from clients that exceed it.
Banned IP filtering
Connections from banned IPs are closed before login logic runs, which reduces the load they cause.

⚠️ Versions 1.0.11 to 1.0.13 have an oversight allowing unwhitelisted or banned players to still see MOTD and player list. This only affects servers with whitelist on. I made a mistake in adding players to the allowed list too early in the signin process. It's unlikely that this was abused on a wide scale as it still…
