Minecraft 1.20.1, 1.16.5用Connectivity MOD

Lightweight mod which solves several connection problems like Login-Timeouts, DecoderException, Packet size limits, Ghostblock issues, Payload too large and more. It also offers commands to analyze network traffic and a bunch of debugging utilities, advanced error logging, packet logging etc. Requires Cupboard dependency to be installed in newer versions

• Login timeout
• Play timeout
• Detailed Network statistics
• Fix packet size exceptions during login/play
• Log data of too large packet to show sources
• Log warnings about too large data beeing sent
• Malformed/Malicious traffic protection

The mod is not required on both sides, but offers useful functionality for both sides.

Randompatches (in)compatibility:

Set this in the randompatches.toml config file so random patches does not crash when started alongside connectivity: mixin_blacklist = ["ServerPlayNetHandlerKeepAlive"] Connectivity has some overlap with randompatches and happens to apply first, which makes random patches crash.

Timeoutout/XL packets mod is incompatible/not needed alongside this

If you enjoy this mod consider supporting the development, any support is greatly appreciated.

The development is an unpaid free-time activity, so any support helps being able to spend more time on it. You can support me on Patreon or just spreading the word around.

Network stats and Commands: Commands for network stats show the traffic rate aswell as which packet is causing it. kb is short for kilobyte

Statistics are refreshed once per minute and save a history of up to 5 minutes. All commands have an optional minute count you can give it to display(1-5, 5 is default when no argument is given)

Normally most traffic is caused by chunk packets, modded packets should rarely exceed those. Client side command to show outgoing traffic: /connectivity packetsClient

Server commands:

List traffic rate of all players: /connectivity packetsAllPlayers

List packets by type send to a specific player(example is player Dev): /connectivity packetsPlayer Dev

List all packets sent out by the server by packet type. /connectivity packetsSummary

Print the largest packet of a type to the latest.log, e.g. the packet called MovePacket: /connectivity printpacket MovePacket
