System Security
Apache / Lighttp Security
- 為了預防同一個 IP 同時間佔據太多連線,過去大家好像都用 !LimitIPConn 這個模組,不過 Apache 2.1
- 官方網站: http://dominia.org/djao/limitipconn.html - Apache 1.3 版本 - 有 debian etch 套件, 不過到了 lenny 就沒了(因為是 Apache 1.3)
- 官方網站: http://dominia.org/djao/limitipconn2.html - Apache 2.x 版本 - 非官方 Debian 套件
- <Ubuntu> Apache 2.x 安裝 limitipconn 模組防多線下載
- [參考] 那如果用 Lighttpd 呢?? 從 "lighty > limit amount of concurrent connections by client?", 寫到: In your configuration add "mod_evasive" to server.modules, e.g.:
server.modules = ( "mod_rewrite", "mod_access", "mod_auth", "mod_status", "mod_fastcgi", "mod_compress", "mod_rrdtool", "mod_accesslog", "mod_evasive" );
- Then configure the maximum number of connections per IP like this:
evasive.max-conns-per-ip = 10
