# Extras
|
||||
|
||||
Some extra steps and recommendations when using lazymc:
|
||||
|
||||
Before you use this in production, always ensure starting and stopping the
|
||||
server works as expected by connecting to it once. Watch `lazymc`s output while
|
||||
it starts and stops. If stopping results in errors, fix this first to prevent
|
||||
corrupting world/user data.
|
||||
|
||||
Follow this repository with the _Watch_ button on the top right to be notified
|
||||
of new releases.
|
||||
|
||||
## Recommended
|
||||
|
||||
- [Protocol version](./protocol-version.md):
|
||||
_set correct Minecraft protocol version for the best client compatability_
|
||||
- [Proxy IP](./proxy-ip.md):
|
||||
_fix incorrect client IPs on Minecraft server, notify server of correct IP with `PROXY` header_
|
||||
|
||||
## Tips
|
||||
|
||||
- [bash with start command](./command_bash.md):
|
||||
_how to properly use a bash script as server start command_
|
||||
|
||||
## Experimental features
|
||||
|
||||
- [Join method: lobby](./join-method-lobby.md):
|

# Protocol version
|
||||
|
||||
The Minecraft protocol uses a version number to distinguish between different
|
||||
protocol versions. Each new Minecraft version having a change in its protocol
|
||||
gets a new protocol version.
|
||||
|
||||
## List of versions
|
||||
|
||||
- https://wiki.vg/Protocol_version_numbers#Versions_after_the_Netty_rewrite
|
||||
|
||||
## Configuration
|
||||
|
||||
In `lazymc` you may configure what protocol version to use:
|
||||
|
||||
[`lazymc.toml`](../res/lazymc.toml):
|
||||
|
||||
```bash
|
||||
# -- snip --
|
||||
|
||||
[public]
|
||||
# Server version & protocol hint.
|
||||
# Sent to clients until actual server version is known.
|
||||
# See: https://git.io/J1Fvx
|
||||
version = "1.17.1"
|
||||
protocol = 756
|
||||
|
||||
# -- snip --
|
||||
```
|
||||
|
||||
It is highly recommended to set these to match that of your server version to
|
||||
allow the best compatibility with clients.
|
||||
|
||||
- Set `public.protocol` to the number matching that of your server version
|
||||
(see [this](#list-of-versions) list)
|
||||
- Set `public.version` to any string you like. Shows up in read in clients that
|
||||
have an incompatibel protocol version number
|
||||
|
||||
These are used as hint. `lazymc` will automatically use the protocol version of
|
||||
your Minecraft server once it has started at least once.

# Proxy IP
|
||||
|
||||
lazymc acts as a proxy most of the time. Because of this the Minecraft server
|
||||
will think all clients connect from the same IP, being the IP lazymc proxies
|
||||
from.
|
||||
|
||||
This breaks IP banning (`/ban-ip`, amongst other IP related things). This may be
|
||||
a problematic issue for your server.
|
||||
|
||||
Luckily, this can be fixed with the [proxy header](#proxy-header). lazymc has
|
||||
support for this, and can be used with a companion plugin on your server.
|
||||
|
||||
## Proxy header
|
||||
|
||||
The `PROXY` header may be used to notify the Minecraft server of the real client
|
||||
IP.
|
||||
|
||||
When a new connection is opened to the Minecraft server, the Minecraft server
|
||||
will read the `PROXY` header with client-IP information. Once read, it will set
|
||||
the correct client IP internally and will resume communicating with the client
|
||||
normally.
|
||||
|
||||
To enable this with lazymc you must do two things:
|
||||
- [Modify the lazymc configuration](#configuration)
|
||||
- [Install a companion plugin](#server-plugin)
|
||||
|
||||
## Configuration
|
||||
|
||||
To use the `PROXY` header with your Minecraft server, set `server.send_proxy_v2`
|
||||
to `true`.
|
||||
|
||||
[`lazymc.toml`](../res/lazymc.toml):
|
||||
|
||||
```toml
|
||||
# -- snip --
|
||||
|
||||
[server]
|
||||
send_proxy_v2 = true
|
||||
|
||||
# -- snip --
|
||||
```
|
||||
|
||||
Other related properties, you probably won't need to touch, include:
|
||||
|
||||
- `server.send_proxy_v2`: set to `true` to enable `PROXY` header for Minecraft server
|
||||
- `join.forward.send_proxy_v2`: set to `true` to enable `PROXY` header forwarded server, if `forward` join method is used
|
||||
- `rcon.send_proxy_v2`: set to `true` to enable `PROXY` header for RCON connections for Minecraft server
|
||||
|
||||
## Server plugin
|
||||
|
||||
Install one of these plugins as companion on your server to enable support for
|
||||
the `PROXY` header. This requires Minecraft server software supporting plugins,
|
||||
the vanilla Minecraft server does not support this.
|
||||
|
||||
If lazymc connects to a Spigot compatible server, use any of:
|
||||
|
||||
- https://github.com/riku6460/SpigotProxy ([JAR](https://github.com/riku6460/SpigotProxy/releases/latest))
|
||||
- https://github.com/timvisee/spigot-proxy
|
||||
|
||||
If lazymc connects to a BungeeCord server, use any of:
|
||||
|
||||
- https://github.com/MinelinkNetwork/BungeeProxy
|
||||
|
||||
## Warning: connection failures
|
||||
|
||||
Use of the `PROXY` header must be enabled or disabled on both lazymc and your
|
||||
Minecraft server using a companion plugin.
|
||||
|
||||
If either of the two is missing or misconfigured, it will result in connection
|
||||
failures due to a missing or unrecognized header.
|
||||
|
||||
## Warning: fake IP
|
||||
|
||||
When enabling the `PROXY` header on your Minecraft server, malicious parties may
|
||||
send this header to fake their real IP.
|
||||
|
||||
To solve this, make sure the Minecraft server is only publicly reachable through
|
||||
lazymc. This can be done by setting the Minecraft server IP to a local address
|
||||
only, or by setting up firewall rules.
