1-2-3-topshiriq


1-laboratoriya
Mavzu: Tarmoq qurilmalarida dastlabki xavfsizlik sozlamalarini o’rnatish-telnet,ssh
Ishdan maqsad.Tarmoq qurilmalarida dastlabki xavfsizlik sozlamalarini telnet va ssh protokollarini sozlashni o’rganish

SSH protokollari
Ishni bajarish tartibi
1.cisco packet tracer dasturini ishga tushiramiz

2.Kompyuterlarga ip manzil beramiz:

3.Tekshirib ko’ramiz



Telnet protokoli
Ishni bajarish tartibi
1.Routerni sozlaymiz:
Router>enable
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int GigabitEthernet 0/0
Router(config-if)#no shutdown

Router(config-if)#

%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)#ip address 192.168.10.1 255.255.255.0

Router(config-if)#exit
