Bungeecord like forwarding of IP and UUID

[zaikindenis]

Could you add the ip_forward option like on bungeecord for IP and UUID forwarding to craftbukkit ?

Hi, infrared already has UUID forwarding as it lets the backend server do authentication.
Infrared also has proxyprotocol and Real_ip support to pass through players ips.

[zaikindenis]

"proxyProtocol": false,
"realIp": true,

tcpdump connect packet -> test.example.com///IP:PORT///1639306316c..

this works on sheme: infrared ( "realIp": true)->BungeeCord(ip_forward=true)->craftbukkit

but not work if: infrared ( "realIp": true)->craftbukkit

BungeeCord ip_forward use other pakets to send to craftbukkit real ip and uuid

[lhridder]

Have you actually installed the RealIP plugin to retrieve these addresses? Otherwise everybody could spoof their ip

I see, thats actually interesting. They must have implemented some kind of protocol between BungeeCord and Craftbukkit let me see if there is any documentation on it.

https://github.com/ME1312/VanillaCord

this project is patching the vanilla kernel
and the kernel works on the same protocol as BungeeCord->craftbukkit

[zaikindenis]

not work: infrared ( "realIp": true)->spigot (bungeecord: true)

work fine: infrared ( "realIp": true)->BungeeCord(ip_forward=true)->spigot (bungeecord: true)
connect packet: test1.example.com///(IP):(PORT)///(timestamp)(ZERO byte)(IP)(ZERO byte)(UUID)(ZERO byte)(DATA)dd02
(UUID)= 32 byte user ID
(DATA) = [{"name":"textures","value":"ewogICJ0aW1lc3RhbXAiID.....iePxn5d","signature":"qL7L3BADz........."}] - present on official game

if you rewrite your code on function UpgradeToIPForward
s := strings.Split(clientAddr.String(), ":") addr = fmt.Sprintf("%s///%s///%d\x00%s\x0012345678911234567892123456789312", addrWithForge[0], clientAddr.String(), timestamp.Unix(), s[0])
work fine, but 12345678911234567892123456789312 = static UUID for test.
how to get orignal UUID and DATA it I didn’t understand

[haveachin]

Wait, what? RealIP is only for the TCPShield Plugin called RealIP. What exactly would be the setup that you want to work?
infrared -> spigot or infrared -> bungeecord -> spigot?

Is this the protocol change that Spigot is looking for to have native IP (+UUID+Skin data) pass thru?
(ZERO byte)(IP)(ZERO byte)(UUID)(ZERO byte)(DATA)dd02

[zaikindenis]

I want it to work infrared -> spigot

infrared -> bungeecord -> spigot, allready work

[lhridder]

then you can install the realip plugin version 2.4 or use proxyProtocol with https://github.com/riku6460/SpigotProxy

[zaikindenis]

VanillaCord has the same protocol like spigot but no plugins are available.

that's why I wanted to suggest that you implement forwarding IP + UUID + Skin data

[lhridder]

UUIDs and Skins already gets forwarded as infrared is not a man in the middle proxy like bungeecord which handles the authentication part itself

So I am using AMP by cubecoders and the realIP is not being passed. I see there is a mention of a plugin. Is this a need to pass the client public IP to the server or is this a 3rd party online service? I dont want to use a online service just forward the IP from infrared to my minecraft instance.

Hello. Proxy protocol works by appending some data including the IP of the player to the server. As this is change is different to standard Minecraft server protocol, the server sees it as a malformed packet and basically drops it. For proxy protocol to work, a plugin is required as it reads the connection packet and is able to understand the proxy protocol data that has been appended to the connection packet.
