Merhaba,<\/p>\n

Bu yaz\u0131m\u0131zda sizlere Linux i\u015fletim sistemlerinde IP banlama<\/strong> i\u015fleminin nas\u0131l yap\u0131laca\u011f\u0131n\u0131 ve banlanan bir IP adresinin nas\u0131l kald\u0131r\u0131laca\u011f\u0131n\u0131<\/strong> ad\u0131m ad\u0131m anlataca\u011f\u0131z.
Sunucu y\u00f6netimi yaparken, zaman zaman k\u00f6t\u00fc niyetli trafi\u011fi veya sald\u0131r\u0131 giri\u015fimlerini engellemek i\u00e7in belirli IP adreslerini yasaklaman\u0131z (banlaman\u0131z) gerekebilir.
Linux\u2019ta bu i\u015flem olduk\u00e7a kolayd\u0131r ve iptables<\/strong> arac\u0131 sayesinde birka\u00e7 basit komutla yap\u0131labilir.<\/p>\n

Linux IP Banlama (Engelleme) \u0130\u015flemi<\/h3>\n

Linux sistemlerde iptables<\/strong> kuruluysa, a\u015fa\u011f\u0131daki komutu kullanarak istedi\u011finiz IP adresini engelleyebilirsiniz:<\/p>\n

\n
iptables -A INPUT -s BANLANACAK_IP -j DROP\r\n<\/code><\/pre>\n<\/div>\n
A\u00e7\u0131klama:<\/strong><\/p>\n

    Bu komut, 192.168.1.100<\/code><\/strong> IP adresinden gelen t\u00fcm ba\u011flant\u0131 isteklerini engeller.<\/p>\n
    Bu y\u00f6ntem \u00f6zellikle SSH sald\u0131r\u0131lar\u0131, spam g\u00f6nderimleri veya belirli IP\u2019lerden gelen yo\u011fun istekleri kesmek i\u00e7in olduk\u00e7a etkilidir.<\/p>\n
