ensp實驗--------telnet登錄認證

 

第一步，配一下各個路由器以及接口的ip，嘗試ping一下保證連通性

R1
<Huawei>sys
[Huawei]int GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]ip address 10.1.1.254 24
R2
<Huawei>sys
[Huawei]int GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]ip address 10.1.1.1 24
R3
<Huawei>sys
[Huawei]int GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]ip address 10.1.1.2 24

 第二步，在R1上配置登錄認證，配置登錄密碼為123

R1
[Huawei]sysname R1
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode password 
[R1-ui-vty0-4]set authentication password cipher 123

第三步，在R2或R3上telent一下R1，登錄R1

<R3>telnet 10.1.1.254
Trying 10.1.1.254 ...
Press CTRL+K to abort
Connected to 10.1.1.254 ...


Login authentication

      of current VTY users on line is 1.
      The current login time is 2020-10-04 23:01:54.

　　輸入密碼后登錄。

最后看看R1上的用戶數：

 

可以看到R3的用戶已經登錄上R1了，登錄方式為Telnet
