Welcome to this free Cisco CCNA Packet Tracer Practice Lab.
2
You can download the lab file from the link in the description.
3
See if you can complete the lab yourself first, and then continue watching this video if you have any trouble,
4
or watch it afterwards to check your solution.
5
In this lab, we will be working with two routers, R1 and R2.
6
We will configure basic security on the routers by using the enable password, which is used to enter privileged exec mode,
7
also known as enable mode.
8
I will only work with one of the routers in this video for the sake of time,
9
but I highly recommend that you perform the configurations on both of the routers for practice.
10
Repetition is essential to become familiar with the command Handline Interface or CLI.
11
Step 1 is to connect the two routers by their Gigabit Ethernet 00 interfaces.
12
I will refer to these as the Gig00 interfaces.
13
Click on Connections in the bottom left and select the cable.
14
Connect it to the Gig00 interface on R1 and then R2.
15
There we have it!
16
Step 1 is complete.
17
Step 2 is to set the host names according to the network diagram, that is to R1 and R2.
18
Click on each router and then select CLI to access the command line interface from which we will configure each router.
19
The current hostname for each router is displayed here.
20
As you can see, each router is currently named Router.
21
To change the hostname of a router, we must enter
22
Global Configuration mode, however to get there we must first enter
23
Privileged Exec mode.
24
This is achieved by using the Enable command.
25
To demonstrate a shortcut, I will use the exit command to return to the previous exec mode.
26
Notice that you can enter privileged exec mode by simply typing en.
27
You can also type en and then use tab to autocomplete it to enable, but this isn't necessary, en alone is fine.
28
E, however, is too short, and we are told this is an ambiguous command.
29
This is because there are other potential commands that begin with E, which we can see by typing E and then a question mark.
30
As you can see, there are two potential commands, enable and exit.
31
So if you just enter E, the router doesn't know which command you mean.
32
However, enable is the only command beginning with en, so en is all the router needs to know which command you mean.
33
Now that we are in privileged exec mode, we can use the configure terminal command to get to global configuration mode.
34
If you want to use shortcuts again as we did with enable and en, the shortest version of the configure terminal command is conf t.
35
From here we can set the hostname of the router.
36
This is done with the hostname command.
37
I will enter hostname R1.
38
As you can see, the hostname has changed from router to R1.
39
Change the hostname on R2 as well, and then step 2 is complete.
40
Step 3 is to set the enable password on each router to Cisco.
41
The enable password is used to enter privileged exec mode, which as I mentioned before is also called enable mode.
42
Previously we had no password set, so we were able to enter privileged exec mode without any password.
43
Now we are going to protect privileged exec mode so that only administrators can access it.
44
The command is simple, and it is done in global configuration mode, which we are already in.
45
Type enable password cisco.
46
That's it.
47
Now let's test it out.
48
From here I will use the exit command twice.
49
Once to bring me back to privileged exec mode, and then once again to bring me back to exec mode.
50
Now I will use the enable command again.
51
However, this time I am asked for a password.
52
The characters do not appear as I type.
53
However, if I type the password Cisco correctly and press enter, I am brought to privileged exec mode.
54
Now let's see what happens if I fail to enter the correct password.
55
I enter the wrong password once, twice, and then three times before being rejected for having bad secrets.
56
Now I will try again with the correct password, and I'm in.
57
Step 3 is now complete.
58
Step 4 is simply to view the password in the running configuration.
59
The running configuration is the current configuration of the router, whether or not you have actually saved it.
60
If you turn off the router without saving the running configuration, you will lose any changes.
61
If you want to keep your changes, you will save them to what's called the startup configuration.
62
That will be for another lab.
63
To view the running configuration, use the show running config command from privileged exec mode, which we are already in.
64
You can abbreviate it to, for example, shrun.
65
Enter the command, and you can see the password right here, with the exact command we used before, enable password cisco.
66
Step 4 asks if the password is encrypted, meaning translated into an unreadable code,
67
to protect it from being discovered by people who should not know the password.
68
As you can see it is not encrypted, it is written in clear text right here,
69
Cisco, so the answer is no. Step 4 is now complete.
70
Step 5 is to enable password encryption on the router.
71
We can protect passwords by encrypting them to render them unreadable.
72
This is done from global configuration mode with the command service password hyphen encryption.
73
I will enter the command and now step 5 is complete.
74
Step 6 is to once again view the running config.
75
I will use the same command as before, and now let's check the password.
76
However, the command doesn't work.
77
That is because we are currently in global configuration mode, and showrunnconfig must be entered from privileged exec mode.
78
Now, I could type exit to drop back to privileged exec mode, and then enter the command.
79
But there is one more way.
80
If I type do in front of the command, I can enter it from global configuration mode.
81
Do show running config.
82
There we go.
83
Let's look at the password.
84
You can see here enable password followed by a 7 and then a string of other numbers.
85
The password has successfully been encrypted.
86
Although we didn't type this 7 when we entered the command, it refers to the type of encryption used.
87
There are other types as well, but that's not something to worry about now.
88
The string of numbers that follow are the password Cisco, encrypted to be unreadable, so that anyone looking over our shoulder can't read the password.
89
Keep in mind that the encryption used in the Service Password Encryption command isn't very secure and can be cracked,
90
but this at least renders the password safe from someone simply glancing over your shoulder.
91
Step 6 is complete.
92
Step 7 is to disable password encryption.
93
We enabled password encryption with the Service Password Encryption command.
94
Now we will simply type no, followed by the same command.
95
No Service Password Encryption.
96
That's it.
97
Step 7 is now complete.
98
Step 8 is once again to view the password in the running configuration.
99
This time I'll exit down to privileged exec mode and type show running config to view the running configuration.
100
As you can see, the password is still encrypted.
101
Why is that, even though we disabled password encryption?
102
Well, disabling password encryption will prevent future passwords from being encrypted.
103
However, it does not unencrypt passwords that are already encrypted.
104
So the answer to step 8 is yes, the password is encrypted.
105
Step 8 and the lab are both now complete.

Bu videoyla nasıl çalışılır
- Videonun tamamını konuşmadan bir kez dinleyin ve bilmediğiniz kelimeleri not edin.
- Normal hızda cümle cümle tekrar edin; ritminiz konuşmacıyla aynı olana kadar her cümleyi yineleyin.
- Kendinizi kaydedin ve orijinaliyle karşılaştırın; password, privilege, exit gibi kelimelere özellikle dikkat edin.
Gölgeleme Tekniği Nedir?
Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
