&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
PRAKTIKUM 11 — Integrated OS Lab&lt;br /&gt;
Ubuntu sebagai Controller • OpenWRT sebagai Router • Android sebagai Client&lt;br /&gt;
Tujuan Praktikum&lt;br /&gt;
Setelah menyelesaikan praktikum ini, mahasiswa mampu:&lt;br /&gt;
Mengorkestrasi tiga OS berbeda dalam satu sistem terintegrasi&lt;br /&gt;
Mendesain topologi jaringan yang realistis dan aman&lt;br /&gt;
Mengkonfigurasi routing &amp;amp; firewall berbasis kernel&lt;br /&gt;
Menyajikan layanan dari Ubuntu dan mengaksesnya dari Android&lt;br /&gt;
Menganalisis alur data lintas OS (kernel ↔ user space ↔ jaringan)&lt;br /&gt;
Filosofi inti:&lt;br /&gt;
Di dunia nyata, sistem selalu multi-OS. Nilai engineer terlihat dari kemampuan mengintegrasikan, bukan sekadar mengonfigurasi satu OS.&lt;br /&gt;
Gambaran Arsitektur Lab&lt;br /&gt;
[ Android x86 ]  &amp;lt;-- client (untrusted)&lt;br /&gt;
        |&lt;br /&gt;
        |  TCP/IP&lt;br /&gt;
        |&lt;br /&gt;
[ OpenWRT x86 ]  &amp;lt;-- router / firewall / policy&lt;br /&gt;
        |&lt;br /&gt;
        |  routing + NAT&lt;br /&gt;
        |&lt;br /&gt;
[ Ubuntu Server 24.04 ]  &amp;lt;-- controller / services&lt;br /&gt;
Peran kunci:&lt;br /&gt;
Ubuntu: controller (server, monitoring, orchestration)&lt;br /&gt;
OpenWRT: router (routing, firewall, policy enforcement)&lt;br /&gt;
Android: client (end-user system, sandboxed)&lt;br /&gt;
Persiapan Lingkungan&lt;br /&gt;
Spesifikasi &amp;amp; Prasyarat&lt;br /&gt;
Host: Ubuntu Desktop 24.04&lt;br /&gt;
Hypervisor: VirtualBox (+ GNS3 opsional)&lt;br /&gt;
VM:&lt;br /&gt;
Ubuntu Server 24.04 (2–4 CPU, 4–8 GB RAM)&lt;br /&gt;
OpenWRT x86 (1 CPU, 256–512 MB RAM)&lt;br /&gt;
Android x86 (2 CPU, 2–4 GB RAM)&lt;br /&gt;
Jaringan:&lt;br /&gt;
Internal Network untuk lab&lt;br /&gt;
NAT opsional untuk internet&lt;br /&gt;
Gunakan snapshot VM sebelum mulai.&lt;br /&gt;
Konfigurasi OpenWRT sebagai Router&lt;br /&gt;
IP Addressing (Deterministik)&lt;br /&gt;
OpenWRT (br-lan): 192.168.100.1/24&lt;br /&gt;
Cek:&lt;br /&gt;
ip addr&lt;br /&gt;
ip route&lt;br /&gt;
DHCP (Opsional, Disarankan)&lt;br /&gt;
Pastikan DHCP aktif agar Android mudah mendapat IP.&lt;br /&gt;
uci show dhcp&lt;br /&gt;
/etc/init.d/dnsmasq restart&lt;br /&gt;
Firewall Dasar (Zona)&lt;br /&gt;
Konsep security zone:&lt;br /&gt;
LAN: Android&lt;br /&gt;
WAN/CTRL: Ubuntu&lt;br /&gt;
Cek aturan:&lt;br /&gt;
uci show firewall&lt;br /&gt;
Firewall OpenWRT dieksekusi oleh kernel networking stack—bukan sekadar aplikasi.&lt;br /&gt;
Ubuntu sebagai Controller&lt;br /&gt;
Static IP Ubuntu&lt;br /&gt;
Set 192.168.100.10/24, gateway 192.168.100.1.&lt;br /&gt;
sudo nano /etc/netplan/01-lab.yaml&lt;br /&gt;
sudo netplan apply&lt;br /&gt;
Verifikasi:&lt;br /&gt;
ip a&lt;br /&gt;
ip route&lt;br /&gt;
ping 192.168.100.1&lt;br /&gt;
&lt;br /&gt;
Layanan Controller (Contoh Nyata)&lt;br /&gt;
Web server ringan untuk observasi lintas OS:&lt;br /&gt;
sudo apt update&lt;br /&gt;
sudo apt install -y python3&lt;br /&gt;
python3 -m http.server 8080&lt;br /&gt;
Buka port (UFW):&lt;br /&gt;
sudo ufw allow 8080&lt;br /&gt;
sudo ufw enable&lt;br /&gt;
Android sebagai Client&lt;br /&gt;
Koneksi Jaringan&lt;br /&gt;
Pastikan Android mendapat IP 192.168.100.x.&lt;br /&gt;
Cek (ADB):&lt;br /&gt;
adb shell ip addr&lt;br /&gt;
adb shell ip route&lt;br /&gt;
Uji Konektivitas&lt;br /&gt;
adb shell ping -c 3 192.168.100.1&lt;br /&gt;
adb shell ping -c 3 192.168.100.10&lt;br /&gt;
Akses Layanan Ubuntu&lt;br /&gt;
Dari browser Android:&lt;br /&gt;
http://192.168.100.10:8080&lt;br /&gt;
Observasi lintas OS:&lt;br /&gt;
Android app → Android framework → kernel Android → TCP/IP → OpenWRT (routing/firewall) → Ubuntu (service).&lt;br /&gt;
Integrasi &amp;amp; Observasi Sistem&lt;br /&gt;
Monitoring dari Ubuntu&lt;br /&gt;
ss -tulpen&lt;br /&gt;
ip -s link&lt;br /&gt;
journalctl -f&lt;br /&gt;
Monitoring di OpenWRT&lt;br /&gt;
logread -f&lt;br /&gt;
iptables -L -v -n&lt;br /&gt;
Observasi di Android&lt;br /&gt;
adb shell ps -A | head&lt;br /&gt;
adb shell getenforce&lt;br /&gt;
Perhatikan perbedaan model isolasi dan policy di tiap OS.&lt;br /&gt;
Keamanan Berlapis (Defense in Depth)&lt;br /&gt;
Android: sandbox, UID isolation, SELinux enforcing&lt;br /&gt;
OpenWRT: firewall, routing policy, NAT&lt;br /&gt;
Ubuntu: UFW, service hardening&lt;br /&gt;
Contoh kebijakan:&lt;br /&gt;
Android → Ubuntu: allow HTTP (8080)&lt;br /&gt;
Android → Ubuntu: deny SSH (22)&lt;br /&gt;
Implementasi (Ubuntu):&lt;br /&gt;
sudo ufw deny from 192.168.100.0/24 to any port 22&lt;br /&gt;
Failure Scenarios (Wajib Dicoba)&lt;br /&gt;
Matikan firewall OpenWRT → amati perubahan akses&lt;br /&gt;
Putuskan routing → Android gagal akses Ubuntu&lt;br /&gt;
Hentikan service Ubuntu → Android connection refused&lt;br /&gt;
Belajar OS terbaik datang dari kegagalan yang terkontrol.&lt;br /&gt;
Refleksi Akademik (OBE-Oriented)&lt;br /&gt;
Mahasiswa kini mampu:&lt;br /&gt;
Mendesain sistem multi-OS&lt;br /&gt;
Mengintegrasikan jaringan lintas OS&lt;br /&gt;
Menerapkan keamanan berlapis&lt;br /&gt;
Menganalisis alur data lintas kernel &amp;amp; user space&lt;br /&gt;
Berpikir sebagai system architect&lt;br /&gt;
&lt;br /&gt;
