Linux Sunucu ping Kapatma ve Açma

Aşağıdaki komutları uygulayarak ping’i kapatabilir veya açabilirsiniz. Ping’e kapalı olması bazı güvenlik nedeni ile avantaj olarak kullanılabilmektedir.

Geçici olarak kapatmak için;

sysctl -w net.ipv4.icmp_echo_ignore_all=1

Reboot attığınızda eski haline dönecektir.

Kalıcı olarak kullanmak istiyor iseniz /etc/sysctl.conf dosyasını editleyerek ilgili komutu uygun bir yere yerleştirmeniz yeterli olacaktır.

Not: Açmak istediğinizde ilgili komutu silmek yerine 1 yazan yeri 0 olarak düzenlemeniz yeterli olacaktır.
