I've got a spawn prison, right? The right kind, one block width and two block height made by modcrete, so theres no space for anyone new to escape without me letting them out. I've never actually witnessed anyone escaping, and as far as I know that kind of prison is inescapable >_> right? Well, every morning I wake up to a new truckload of grief. I've never seen anyone get in or out or delete the modcrete, and only two people are admin, my girlfriend and me. And one of her creations was destroyed which she spent quite a while on, so I doubt shes the one doing it.
In short, have people figured out a way to escape every kind of spawn prison? Are people cheating their way to being admin? If it keeps up I'm going to have to make my server private, which defeats the purpose of having a server for people to build in =\
It's been happening for about a week now. If it were a one-off, I'd consider maybe its a mistake, but each night I check and double check that its locked and it still happens. I can't lose sleep monitoring the server at night to see how its happening, but it's either some kind of glitch/hack or something to do with grievers making themselves OP. That guy who said he hacked the client sounds plausible.
Client hacks aren't old news. Server update could fix it I suppose. Checking to see if the client ever passes over a tile that's got a block and kick them. Only problem is if they get a lag strike and get kicked for no good reason.
Because certain players frequent the server and come in to build stuff sometimes, which I usually let them in to do before I go to sleep. I don't want to have to shut down my server just to stop a bunch of jerk-offs from wrecking it, the whole grief ordeal is really starting to ruin the game experience for me. Without a reliable way to protect your server (besides making it private, which kind of defeats the point) its not really worth building anything since its just going to be destroyed almost immediately.
With certain hacked clients, that prison is incredibly easy to break out of. All they need to do is place a "ghost block" at their feet and respawn, which will pop them out of the prison. A lot of griefers have this, and a person I know, that uses his hacked client for good, explained a lot of it to me. He created a spawn prison that's actually very complex and should trap 98% of griefers.
Since opcrete is actually serverside, it's hard to replicate with a client hack, although it can be done. The most a script-kiddie could do with the generic hacked client is to "ghost block" their way out of the prison and through other opcrete barriers. The ghost block only shows up to them, and the server doesn't recognize it, so the other players see nothing, can delete nothing, and can build off nothing. This is how people "fly." They create a series of "spawns" on these blocks that only they can see, and the blocks get deleted as the hacker moves.
It's all rather complicated and clever, but it's still a bother to deal with sometimes.
Actually it wouldn't even take that much to get out of an admincrete box. You can just edit the login packet the server sends to you to change your admin level to 100; Then you can break admin blocks and the official server will do nothing but shrug it off.
Otherwise, yeah, the client and server can let people teleport anywhere they want in the map and there is nothing you can do about it. Server can't even tell the difference between a teleport and normal movement.
