So I run Litebans on my server because it seems like a reliable plugin, but one of the commands /dupeip doesn't seem to work. It lauches the command but it shows every player that has joined the server. I want it to show just the players IP, their alts and if they're banned, online or offline. Is there any way to fix that?
Why not ask for support from the developer? you did pay for it, right?
This is one of the most active developers, so ask the developer instead.
I don't believe it's litebans anymore as I have tested other plugins that have the same command. It just shows the server IP and not the players ip, would you know how to allow the server to see players ips?
If you have any form of DDoS protection which masks IP addresses (e.g. ProxyPipe), or if your server is being forwarded packets by a proxy with NAT, then you need to figure out how to forward IP addresses with your particular setup, BungeeCord IP forwarding won't help if players have the same IP address upstream.
Btw this is a rather big security risk, I could have joined your server and completely taken over because of your settings. Like literally destroyed all your servers under bungeecoord. I won't explain how, as that is not important. But other's with not so nice intentions know this too.
