💻 Setting Up DHCP Server on Ubuntu Server 23.10

The video begins with the host, Riswan, greeting viewers and introducing the topic: configuring a DHCP server on Ubuntu Server 23.10. The server has been installed on VirtualBox, and Riswan guides viewers to access the network settings of the virtual machine. He emphasizes the importance of setting up the network adapter to allow communication between the virtual machine and the host machine, which is connected to a LAN network. Riswan then proceeds to power on the Ubuntu Server 23.10 and logs in as the user 'itbi'. The video highlights the command-line interface (CLI) nature of the server, where all commands must be typed in. Riswan checks the IP address of the server, which is 192.168.1.2, and verifies that the server is connected to the internet by pinging Google.com. The host then prepares to install the necessary application to create a DHCP server.

🛠️ Configuring the ISC DHCP Server

In this segment, Riswan explains the process of installing the ISC DHCP server, an application used to create a DHCP server within a network. He ensures that the server is connected to the internet before proceeding with the installation. After successfully installing the ISC DHCP server, Riswan moves on to configure it to match the network's IP configuration. He opens the configuration file using the 'nano' command and navigates to the 'interface' section, where he adds the network interface 'ens0s3'. Riswan then saves the changes and proceeds to configure another file located in '/etc/dhcp/dhcpd.conf'. He scrolls to the bottom of the file and removes comments to activate the IP address range configuration. He sets the subnet to 192.168.1.0 with a netmask of 255.255.255.0 and defines the range of IP addresses from 192.168.1.100 to 192.168.1.130 that will be automatically assigned to client computers. Riswan also configures the DNS servers to Google's public DNS (8.8.8.8 and 8.8.4.4) and sets the subnet mask and default gateway to 255.255.255.0 and 192.168.1.1, respectively.

🌐 Activating and Testing the DHCP Server

The final paragraph covers the activation of the ISC DHCP server and testing its functionality. Riswan instructs viewers to run the server using the command 'sudo systemctl start isc-dhcp-server'. He then checks the status of the application and confirms that it is running. To test the DHCP server, Riswan configures a client computer, which is a Windows 10 machine, to obtain an IP address automatically from the DHCP server. He navigates to the network settings and ensures that the computer is set to obtain an IP address and DNS server automatically. Upon configuring, the client computer successfully receives an IP address (192.168.1.101) within the predefined range from the DHCP server. Riswan concludes the video by summarizing the steps and wishing viewers well.

perintah ini dibaca sebagai program eh

jika tanda pagarnya masih

ada maka baris ini dibaca sebagai

komentar jadi dia tidak bisa

dieksekusi maka kita hilangkan dulu

barisnya baris

pagarnya kita hapus dulu tanda pagarnya

nah untuknya sendiri kita atur sesuai

dengan subnet yang ada di jaringan

kita untuk jaringan yang gunakan ini

submitnya

[Musik]

192.168.1.0 nah ini sesuai dengan IP

address IP server yang kita gunakan

untuk netmx-nya yaitu

255.255.255.0 sudah diganti

eh kemudian range-nya yaitu IP yang akan

kita berikan ke Komputer klien yang

merequest IP secara otomatis ya jadi

kita mulai dari

[Musik]

192.168.1.100 sampai dengan

[Musik]

192.168.1.130 jadi di rentang IP inilah

yang akan diberikan ke Komputer klien

yang eh merequest IP address dari DHCP

server untuk option Domain Name

servernya atau dns-nya saya buat di sini

openns dari Google yaitu

8.8.8.8 kemudian op domain name-nya

8.8.4.4 Nah untuk obsnmas yang akan

diberikan yaitu

255.255.255.0 dan Ops router atau

gateway-nya yaitu 192.168.1.1

oke nah jadi kita definisikan dulu

Berapa IP address yang kita berikan

kemudian DNS

dan sub netmas serta default getway-nya

Nah untuk broadcast-nya di kita

definisikan juga yaitu 192.108.1.255

[Musik]

oke nah untuk option domain name-nya

8.8.4.4 ini tidak usah digunakan jadi

tinggal ketika aja tanda pagar di bagian

jalankan dulu aplikasi ini supaya bisa

eh digunakan di dalam jaringan

Oke jika sudah dijalankan selanjutnya

yaitu kita akan e mengecek di bagian

Komputer klien untuk merequest IP

address

dari server DHCP Nah untuk komputer

kalian yang saya gunakan di sini adalah

Windows 10 atau komputer utama yang Saya

instalkan virtual box Nah kita masuk ke

bagian

internetnya

kemudian kita setting di bagian internal

protokol versi 4nya

yang

jadi pilihannya adalah uptain an IP

address automatically kemudian obtain

DNS maka dengan mengkonfigurasi seperti

itu dia akan Mau request IP address ke

DHCP server sehingga DP server akan

memberikan IP address sesuai dengan

konfigurasi dari DHCP server itu sendiri

ke

jaringan atau ke Komputer klien yang ada

di dalam jaringan nah ini dia IP yang

diperoleh yaitu

192.168.1. 101 sesuai dengan range IP

yang kita berikan dimulai dari 100

sampai 130

Oke demikianlah cara konfigurasi DHCP

server pada Ubuntu Server

23.10
