標題: 怎么防止惡意掃描
查看服務器日志發現大量掃描/forum.php?mod=attachment開頭的URL，光這個掃描記錄好長好長下拉都拉不完，問題訪問的ip很少有重復的，很多的ip

雖然都被攔截了但也大量消耗資源引起網站卡頓延遲

怎么設置論壇未登錄用戶嘗試訪問附件下載路徑 /forum.php?mod=attachment&aid=
開頭自動封禁ip N小時
截取的片段：

寶塔有免費的防火墻 開啟UA攔截 禁止海外【最好是從域名解析那邊禁止海外】

早封禁國外一年多了，都是國內的
我在研究看是用nginx實現還是利用dz自帶功能修改代碼實現

這是被爬了吧

無所謂了
已經把日志中的所有IP利用ai全部提取出來，不管是掃描器或者是爬蟲，只要帶mod=attachment路徑的，直接拎出來甩手全部扔進防火墻ip黑名單了，即便是爬蟲也是不遵守robots.txt協議無視User-agent: *

另外現在的大環境已經不靠SEO了

你在這里問這個問題就是多余

已經解決
source/module/forum/forum_attachment.php
增加判斷邏輯代碼
source/function/function_core.php
文件增加
添加全局函數，用于自動封禁 IP 并記錄日志，配合nginx設置，完成

回應你說的多余問題
另外我問的不是discuz問題么，為什么叫多余？
如果是經常解答問題的開發者這么說我無話可說 欣然接受，但你也是平等身份這么說不合適吧(Brain-dead)??

能否詳說下，我之前也遇到了，靠防火墻撐著，但攔截還是不夠徹底
