PC3 kompyuterini sozlang: 192.168.2.13 IP-manzil, 255.255.255.0 niqob va 192.168.2.1 asosiy shlyuzlarni bering. 5.2-rasm. Router1 interfeyslarini sozlash. 9. Router1 konsoliga o’ting va xost nomi, maxfiy parol va telnetni “line vty” buyrug’i yordamida sozlang (5.3-rasm): 5.3-rasm. Router1 konsolida xost nomi, maxfiy parol va telnetni sozlash. “Enable secret ‘sizning parolingiz’” buyrug’i marshrutizator foydalanuvchisi uchun parol qo’yish. “line vty” buyrug’i telnetni yoqadi, “0” shunchaki marshrutizatorga bitta chizig’i yoki seansini o’tkazib yuboradi. Agar Sizga bir vaqtning o’zida bir nechta seans kerak bo’lsa, Siz “line vty 0 10“ buyrug’ini kiritishingiz kerak, bu 11 ta mijoz telnetga kira olishini anglatadi. “logging synchronous” buyrug'i har qanday konsol xabarlarini chiqarilishiga yo'l qo'ymaydi, bu esa o'z navbatida konsol rejimida buyruqlar kiritilishini to'xtatishi mumkin. “exec-timeout” buyrug’i shunchaki liniya uchun kutish chegarasini jimlik holatidagi “10 daqiqa”ni o’rnatadi. 10. TelNet bog’lanishni tekshiring: 10.1. Administrator yoki mijoz ShK dan buyruqlar satriga kiring. 10.2.
