Install Nmap dan Netstat di CentOS 7
Oke kali ini share sedikit tutorial instalasi Nmap dan Netstat di CentOS 7. Secara default kedua tools tersebut memang belum terinstall di CentOS 7. Hal ini baru saja saya alami ketika menyewa server baru tadi pagi. Nah berhubung kedua tools tersebut sangat penting, terutama untuk menganalisa servis yang berjalan di port tertentu dan melihat port mana saja yang terbuka, saya juga merekomendasikan teman teman menginstall tools tersebut.
Oke langsung saja ya.
Untuk Netstat, tidak ada paket bernama itu di repository. Untuk mendapatkannya bisa dengan menginstall net-tools.
sudo yum install net-toolsContoh output :
Loaded plugins: fastestmirror
