Cisco routeriga ulanganingizdan so'ng, siz LAN va WAN orqali qurilmangizni
boshqarishingiz
mumkin . Qurilmaga
ulanishlarni
ko'rish
uchun show
line. buyrug'ini bajaring .
Endi SSH-ni kommutatorda sozlaylik - buning uchun siz hostname, domen nomini
ko'rsatishingiz va shifrlash kalitini yaratishingiz kerak.
Router-ni ikki marta bosing va buyruq satriga o'ting. Dastlabki sozlamalarni
o'tkazib yuborish uchun Enter tugmasini bosing .
Чтобы подключить SSH на маршрутизатор, выполните следующие команды
по порядку.
Router> enable

Endi IP-configuration bo'limida shaxsiy kompyuter parametrlarini sozlaylik :
:
Ulanish uchun, kompyuterga buyruq satriga o`tib, quyidagilarni kiriting va Enter
tugmasini bosing :
ssh - l cisco 192.168.1.1
- l – kirish (login) qiymati
сisco – marshrutizatorga ulangan
foydalanuvchi nomi .
192.168.1.1 - marshrutizatorning ip manzili.
Yaratilgan parolni kiriting va ulanish o'rnatiladi.
Show ssh buyrug`i bajarilgandan
so'ng , buyruq satrida SSH protokoli versiyasini tekshirish mumkin.
Vazifa. TelNet va SSH protokollarini sozlang. O`zingizning
IP - manzilingizni
ko'rsating va foydalanuvchini o`zining nomi bilan ulang (username: ismingiz,
password: ismi va guruh raqami).
Nazorat savollari:
1.
TelNet protokoli tavsifini bering .
2.
SSH protokolini tavsiflab bering .
3.
TelNet va SSH protokollari o'rtasidagi farqlarni aytib bering .
4.
Telnet va SSH protokollarining asosiy vazifalari.
5.
SSH protokolining nechta versiyasi mavjud?
