━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

1️⃣ Open SSH configuration file:
────────────────────────────────────
sudo su
nano /etc/ssh/sshd_config

2️⃣ Change the following line:
────────────────────────────────────
FROM:
#PermitRootLogin prohibit-password

TO:
PermitRootLogin yes

💡 Tip: If the line does not exist, just add:
PermitRootLogin yes



3️⃣ OR do it automatically via terminal:
────────────────────────────────────
sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

4️⃣ Restart the SSH service:
────────────────────────────────────
sudo systemctl restart ssh

5️⃣ Confirm the change was applied:
────────────────────────────────────
grep -i "rootlogin" /etc/ssh/sshd_config


✅ Done! You can now log in as root via SSH (make sure root has a password).
