10.2.2.8 Packet Tracer - DNS and DHCP

Packet Tracer - DHCP and DNS Servers
Objectives

Part 1: Configure Static IPv4 Addressing

Part 2: Configure and Verify DNS Records

Background

In this activity, you will configure and verify static IP addressing and DHCP addressing. You will then configure a DNS server to map IP addresses to the website names.
Note: Packet Tracer only simulates the process for configuring these services. DHCP and DNS software packages each have their own unique installation and configuration instructions.

Part 1:    Configure Static IPv4 Addressing
Step 1:   Configure the Inkjet printer with static IPv4 addressing.

The home office computers need to know the printer’s IPv4 address to send information to it. The printer, therefore, must use a static (unchanging) IPv4 address.

a.     Click Inkjet and click the Config tab, which displays the Global Settings.

b.    Statically assign the Gateway address as 192.168.0.1 and the DNS Server address as 64.100.8.8.

c.     Click FastEthernet0 and statically assign the IP address as 192.168.0.2 and the Subnet Mask address as 255.255.255.0.

d.    Close the Inkjet window.

Step 2:     Configure WRS to provide DHCP services.

a.     Click WRS and click the GUI tab, and maximize the window.

b.    The Basic Setup window displays, by default. Configure the following settings in the Network Setup section:

1)     Change the IP Address to 192.168.0.1.

2)     Set the Subnet Mask to 255.255.255.0.

3)     Enable the DHCP Server.

4)     Set the Static DNS 1 address to 64.100.8.8.

5)     Scroll to the bottom and click Save.

c.     Close the WRS window.

Step 3:     Request DHCP addressing for the home laptop.

This activity focuses on the home office. The clients that you will configure with DHCP are Home Laptop and Tablet.

a.     Click Home Laptop and click the Desktop tab > IP Configuration.

b.    Click DHCP and wait until the DHCP request is successful.

c.     Home Laptop should now have a full IP configuration. If not, return to Step 2 and verify your configurations on WRS.

d.    Close the IP Configuration window and then close the Home Laptop window.

Step 4:     Request DHCP addressing for the tablet.

a.     Click Tablet and click the Desktop tab > IP Configuration.

b.    Click DHCP and wait until the DHCP request is successful.

c.     Tablet should now have a full IP configuration. If not, return to Step 2 and verify your configurations on WRS.

Step 5:     Test access to websites.

a.     Close the IP Configuration window, and then click Web Browser.

b.    In the URL box, type 10.10.10.2 (for the CentralServer website) or 64.100.200.1 (for the BranchServer website) and click Go. Both websites should appear.

c.     Reopen the web browser. Test the names for those same websites by entering centralserver.pt.pka and branchserver.pt.pka. Click on Fast Forward Time on the yellow bar below the topology to speed the process.

Part 2:     Configure Records on the DNS Server
Step 1:     Configure famous.dns.pka with records for CentralServer and BranchServer.

Typically, DNS records are registered with companies, but for the purposes of this activity you control the famous.dns.pka server on the Internet.

a.     Click the Internet cloud. A new network displays.

b.    Click famous.dns.pka and click the Config tab > DNS.

c.     Add the following resource records:

d.    Close the famous.dns.pka window.

e.     Click Back to exit the Internet cloud.

Step 2:   Verify the ability of client computers to use DNS.
Now that you have configured DNS records, Home Laptop and Tablet should be able to access the websites by using the names instead of the IP addresses. First, check that the DNS client is working properly and then verify access to the website.

a.     Click Home Laptop or Tablet.

b.    If the web browser is open, close it and select Command Prompt.

c.     Verify the IPv4 addressing by entering the command ipconfig /all. You should see the IP address for the DNS server.

d.    Ping the DNS server at 64.100.8.8 to verify connectivity.

Note: The first two or three pings may fail as Packet Tracer simulates all the various processes that must occur for successful connectivity to a remote resource.

e.     Test the functionality of the DNS server by entering the commands nslookup centralserver.pt.pka and nslookup branchserver.pt.pka. You should get a name resolution showing the IP address for each.

f.     Close the Command Prompt window and click Web Browser. Verify that Home Laptop or Tablet can now access the web pages for CentralServer and BranchServer.

9.1.4.6 Packet Tracer - Subnetting Scenario 1

Topologi

Objectives

Part 1: Design an IP Addressing Scheme
Part 2: Assign IP Addresses to Network Devices and Verify Connectivity

Scenario

In this activity, you are given the network address of 192.168.100.0/24 to subnet and provide the IP addressing for the network shown in the topology. Each LAN in the network requires enough space for, at least, 25 addresses for end devices, the switch and the router. The connection between R1 to R2 will require an IP address for each end of the link.

Part 1: Design an IP Addressing Scheme
Step 1: Subnet the 192.168.100.0/24 network into the appropriate number of subnets.

a. Based on the topology, how many subnets are needed?
b. How many bits must be borrowed to support the number of subnets in the topology table?
c. How many subnets does this create?
d. How many usable hosts does this create per subnet?
Note: If your answer is less than the 25 hosts required, then you borrowed too many bits.
e. Calculate the binary value for the first five subnets. The first subnet is already shown.

Sebenarnya agak bingung juga mau jelasin dari mana, namun yang saya pahami ketika mengerjakan latihan ini adalah bagaimana alokasi IP Address dimana disediakan 1 (satu) IP Address yang kemudian dibagi-bagi/di subnet sehingga mencakup seluruh kebutuhan IP Address berdasarkan topologi yang telah ditentukan.

Subnetting

Hal pertama yang terpikirkan olehku adalah subnet. Ya, karena pembagian/alokasi IP Address jika disediakan 1 (satu) IP Address maka berkaitan dengan subnet/subnetting. Maka yang dilakukan adalah mengotak-atik subnet mask dari IP Address yang telah disediakan tadi.

- Dibutuhkan IP Address untuk 25 hosts

- Tentukan subnet yang memenuhi persyaratan di atas

11111111.11111111.11111111.11100000

Untuk mengetahui jumlah host per subnet gunakan rumus :

2^n-2

dimana : n adalah jumlah angka 0 di oktet terakhir

maka

2^5-2 = 30 (memenuhi syarat butuh 25 hosts)

Berdasarkan kebutuhan tersebut, subnet yang memenuhi adalah /27

Terus ???

Yang saya lakukan adalah menentukan range IP Address yang digunakan dalam 1 subnet.

Biar lebih mudah, aku pake LibreOffice Calc (kayak Excel) untuk menentukan range IP Address.

Alokasi IP Address

Selanjutnya, PAHAMI bagian ini

Step 2: Assign the subnets to the network shown in the topology.

a. Assign Subnet 0 to the LAN connected to the GigabitEthernet 0/0 interface of R1:
b. Assign Subnet 1 to the LAN connected to the GigabitEthernet 0/1 interface of R1:
c. Assign Subnet 2 to the LAN connected to the GigabitEthernet 0/0 interface of R2:
d. Assign Subnet 3 to the LAN connected to the GigabitEthernet 0/1 interface of R2:
e. Assign Subnet 4 to the WAN link between R1 to R2:

Step 3: Document the addressing scheme.

Fill in the Addressing Table using the following guidelines:

a. Assign the first usable IP addresses to R1 for the two LAN links and the WAN link.
b. Assign the first usable IP addresses to R2 for the LANs links. Assign the last usable IP address for the WAN link.
c. Assign the second usable IP addresses to the switches.
d. Assign the last usable IP addresses to the hosts.

Part 2: Assign IP Addresses to Network Devices and Verify Connectivity
Most of the IP addressing is already configured on this network. Implement the following steps to complete the addressing configuration.

Step 1: Configure IP addressing on R1 LAN interfaces.

R1>enable
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface gigabitEthernet 0/0
R1(config-if)#ip address 192.168.100.1 255.255.255.224
R1(config-if)#no shutdown
R1(config-if)#
R1(config-if)#int g0/1
R1(config-if)#ip address 192.168.100.33 255.255.255.224
R1(config-if)#no shutdown
R1(config-if)#

Step 2: Configure IP addressing on S3, including the default gateway.

S3>enable
S3#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
S3(config)#interface vlan 1
S3(config-if)#ip add 192.168.100.66 255.255.255.224
S3(config-if)#no shutdown
S3(config-if)#exit
S3(config)#ip default-gateway 192.168.100.65

S3(config)#

Step 3: Configure IP addressing on PC4, including the default gateway.

PC4 IP Address

Step 4: Verify connectivity.

Cara Ekstrak File .Rar di Linux - Kebutuhan akan kompresi data menjadikan pengguna komputer merasa terbantu, terlebih dengan banyaknya file-file yang ada di komputer menjadikan arsip menjadi sesuatu yang penting. Adanya pengarsipan yang baik tentu akan mempermudah pengguna komputer dalam pengelolaan dokumen sehingga lebih mudah ketika dicarai maupun agar tertata rapi.

Berbagai jenis format penyimpanan berupa arsip dapat dijumpai ketika menggunakan komputer. Sebagai contoh, file dengan ekstensi .rar, .zip, .tar.gz dan lain-lainya. Adapun cara untuk mengekstrak file dengan ekstensi terkait juga berbeda-beda. Namun, pada kesempatan kali ini, saya akan berbagi cara ekstrak file .rar di linux terutama ubuntu menggunakan aplikasi tambahan.

Perlu diketahui bahwa untuk proses ekstrak file berekstensi .rar sedikit berbeda jika dibandingkan ketika menggunakan OS Windows. Pada windows, program yang biasa digunakan untuk ekstrak file terutama berekstensi .rar adalah WinRar. Maka ketika menggunakan os Linux, WinRar tidak akan bisa berjalan kecuali dengan bantuan aplikasi yang disebut dengan Wine. Wine merupakan sebuah aplikasi yang digunakan sebagai 'translator' program aplikasi Windows sehingga dapat berjalan di Linux. Namun, ada cara lain yang lebih mudah ketimbang harus instal Wine lalu baru instal WinRar.

Di Linux sudah tersedia program untuk menangani permasalahan ektraksi file dengan ekstensi .rar. Salah satu yang dapat digunakan adalah unrar. Untuk mengintall unrar lakukan perintah dibawah ini.

Gambar 1. Cara Instal unrar

Adapun cara untuk menggunakan unrar adalah sebagai berikut.

Untuk mengekstrak file.rar file ke direktori dimana file tersebut diletakkan, masukkan:

$ unrar e file.rar

Nah, itu dia cara untuk ekstrak file.rar. Selamat mencoba dan semoga berhasil.
