已解决 [服务器]服务器MC被人入侵

[sato]

本人是服务器小白，最近用校园网开了个原版生存服务器和舍友一起玩，但是才第二天就遭人入侵了，他先是顶了正在服务器里面的舍友的号（lzs）上服务器（登陆的ip变了），然后再是以我的op账号身份（osicy）登陆上去且我当时并不在线，然后就是各种破坏，我们花一天建好的建筑全没了。
想来请教以下各位dalao,这个服务器要怎么设置才能防止这种坏人心情、不干人事的东西来破坏服务器啊？我甚至都没想明白我的服务器是怎么被看上的？？？

以下是server的日志信息（前面是ta顶掉我舍友号以及以我的身份登陆，后面是各种破坏，discord那个网站校园网挂梯/子上不去）：

是正版服务器还是盗版服务器，能顶掉就说明UUID是一样的了

官网下的server包，但是把正版验证关了，我和舍友都没买正版

试着换spigot端然后装个登录插件？

居然还有登陆插件！我等会就试试！感谢！

盗版只能用登录插件了（官网指的是哪个服务端？spigot，bukkit还是mojang官方的香草？）建议你把存档和usercache.json挪出来换一个paper或spigot之类的核心。然后去网上对应你的服务端下载对应的插件（要注意有的服务端是没法装插件的），找到plugin文件夹把你下载的jar文件放进去，重启服务器，根据插件的说明配置配置文件就行了
但主要还是不要随便分享服务器端口就是了
