Nmap. Nmap () – Gordon Lyon tomonidan yaratilgan tarmoqni skanerlash dasturi. Nmap dasturini tarmoq paketlarini yuborish orqali kompyuterlar tarmogʻida hostlarni aniqlash, servislarni hamda ularni versiyasini analiz qilish uchun ishlatiladi. Shuningdek, tcp, ftp hamda boshqa portlar holatini koʻrish ham mumkin. Misol. Foydalanishga misol tariqasida berilgan: $ nmap -f -v -A scanme.nmap.org Starting Nmap 6.47 ( https://nmap.org ) at 2014-12-29 20:02 CET Nmap scan report for scanme.nmap.org (74.207.244.221) Host is up (0.16s latency).
