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.
