Closing a player socket / forcing it to time out

[J15t98J]

So.

 

I'm currently writing a Bukkit plugin which allows moderators to ban someone with a slightly different command, so that instead of seeing a ban message when they log in, the server closes / times out the socket they are connecting on, so they just see a connection error and don't suspect anything.

 

However, Bukkit's API doesn't have the ability to close sockets / force them to time out, as far as I can tell. Is there a way to accomplish this with Forge, and if so, how? I know it's a slightly odd request, any help appreciated

this might be useful for the ban hammer mod I'm planning on making.

Any idea on how to do it? I have everything else set up - custom YAML config files, event listeners etc. I just need a way to fake a realistic connection error

sorry. I don't. but I wish i did

What I would try to do (probably won't work) is make it so that it checks to see if the player is on a special ban list (that you create, e.g. specialban.txt or whatever) and if the player is on that list, then don't connect, display the connection error GUI or something similar.

THis could help me with my one other mod I am making call AdditionalCraftServerSecurity  that has a banned mod list and disconnects the play with out them needing my mod on there end.

Mew, I've already got that set up, and just need a way to kick the player without it saying "Disconnected by Server" at the top. Also, displaying the connection error GUI is client side, so I'd have to send a packet (if there is one); otherwise I would have to mod the client, which I don't want to do

I can try and find it I think there is one for internal server error that you some times get on servers.

[J15t98J]

Unfortunately, there isn't, as far as I can see.

[Chibill]

Maybe send it invaled Titleentity data with an existing packet and crash the client?

Or use the serverauth packet to tell it it is not authorized

[J15t98J]

I don't really want to crash the client. What error would the serverauth packet produce?

[Chibill]

I don't know but that is what is used to authariz that player is logged in / online mode.
