Tutorial!!! Instalasi & Konfigurasi DNS Server di Debian 10 Virtualbox

Summary of the tutorial (DNS server on Debian 10 in VirtualBox)

This video is a step-by-step tutorial to install and configure a DNS server on Debian 10 running in VirtualBox. It then verifies DNS resolution and publishes a simple website via Apache.

1) VirtualBox network setup

• The Debian 10 VM is prepared from a previously cloned/installed ISO (the tutorial references an earlier Debian 10 installation video).
• In VirtualBox VM settings:
  • Network mode is changed from NAT to Host-Only Adapter.
  • The adapter is selected (shown in subtitles as something like “Host-Only” / “fann DNI”) so the VM can communicate locally with the host.

2) Configure Debian network IP

• Login as root.
• Edit the network interface using nano (shown as “Nano /etc/…”):
  • Configure a static IP (DHCP disabled for that config).
  • IP address: 192.168.7.7
  • Netmask: 255.255.255.0
• Restart networking (shown as “restart” to apply changes).
• Verification:
  • Confirm the VM IP is now 192.168.7.7/24.

3) Configure Windows host to use the Debian DNS

On Windows:

• Set the adapter to VirtualBox Host-Only Network.
• Configure IPv4:
  • IP: 192.168.7.2 (substitutions may be possible)
  • Subnet: 255.255.255.0
  • Preferred DNS server: 192.168.7.7
• Verification:
  • Ping 192.168.7.7 from Windows to confirm connectivity.

4) Install DNS server packages (bind9 / dnsutils)

• Mount/select the Debian ISO DVDs (referenced as DVD1 and DVD2).
• Use APT to install:
  • bind9
  • dnsutils
• The tutorial includes:
  • Editing the APT source list (security lines are commented out in the tutorial).
  • Installing packages with APT.
  • Checking package state and reinstalling if needed using dpkg and apt purge / apt autoremove (some details appear partially garbled in subtitles).

5) DNS zone configuration (forward + reverse)

The core DNS configuration is done using named zone files under /etc/bind/ (the tutorial uses db.* files and nano editors).

Key actions

• Copy base zone files (e.g., db.local), then create custom DB files:
  • Forward lookup file: based on db.local, renamed to something like db.<domain>
  • Reverse lookup file: based on db.127, renamed to something like db.192.168.7 (reverse in-addr.arpa logic is referenced)

• Update records in those files:

  • Replace localhost with the chosen domain (example domain appears as smakness.net / snackness.net—spelling is inconsistent due to auto-caption errors).
  • Set the A records to 192.168.7.7
  • Ensure both:
    • Root domain records (e.g., @)
    • www records point to the Debian IP.

• Configure DNS main config:

  • Edit /etc/named.conf.
  • Add:
    • A zone for the domain (marked as master;)
    • A reverse zone using 7.168.192.in-addr.arpa
• Restart DNS:
  • Restart bind9.
• Verification:
  • Check that bind9 is running.

6) Install Apache and create a simple webpage

To demonstrate that the DNS mapping works:

• Install Apache:
  • apt install apache2
• Configure a site (vhost):
  • The tutorial copies the default site config to a custom vhost file (spelling appears inconsistent in subtitles).
• Edit the Apache configuration to set:
  • Admin email (changed from localhost to the user’s email)
• Update the web page:
  • Edit /var/www/html/index.html
  • Customize content (e.g., a message like “Welcome to the Apip channel”)

7) Test and verification

The tutorial tests DNS resolution and web access:

• Ping tests:
  • Ping Debian IP: 192.168.7.7
  • Ping the domain name (e.g., smakness.net / snackness.net) to confirm DNS answers
• Browser tests:
  • Open the browser using the IP 192.168.7.7 to verify Apache loads
  • Open the browser using the domain to verify it resolves to the IP and loads the same webpage

Main deliverable / outcome claimed

• A DNS server on Debian 10 is configured successfully:
  • Forward DNS (domain → IP)
  • Reverse DNS (IP → domain)
• The domain name resolves correctly from Windows.
• Apache serves a customized page via both IP and domain.

Main speakers / sources

• Speaker: “Apip” (channel owner/instructor; referenced in subtitles as “apip it”)
• Source basis: The instructor’s prior Debian 10 installation video and Debian package repositories/ISO media (DVD1/DV D2 mentioned).
