How do I get the login username and password?

[dimmasyusuf]

The default SSH credentials are:

Username: root
Password: casaos

[arvindiscoder]

just tried it. It doesn't work:

📋 Before You Start:

1. Find your container name: docker ps
2. Look for the container with image dockurr/casa (usually named casaos)
3. Choose which option you want (see below)
4. Replace the values in ALL CAPS with your own

Option 1: Custom User Only (Most Secure) ⭐⭐⭐⭐⭐

What this does:

✅ Creates YOUR custom username and password
✅ DISABLES root login (more secure)
✅ SSH starts automatically every time container restarts
✅ Safe to run multiple times (won't duplicate)

Instructions:

Replace these before running:

• CONTAINER_NAME = your Docker container name (check with: docker ps)
• YOUR_USERNAME = your desired SSH username (example: alice)
• YOUR_PASSWORD = your desired SSH password (example: secret123)

Command:

docker exec CONTAINER_NAME bash -c '
USERNAME="YOUR_USERNAME" && \
PASSWORD="YOUR_PASSWORD" && \
grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
# Auto-start SSH - Custom User Only\n\
USERNAME=\"$USERNAME\"\n\
PASSWORD=\"$PASSWORD\"\n\
id \"\$USERNAME\" >/dev/null 2>\&1 || useradd -m -s /bin/bash \"\$USERNAME\"\n\
echo \"\$USERNAME:\$PASSWORD\" | chpasswd\n\
mkdir -p /run/sshd\n\
sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
echo \"PermitRootLogin no\" >> /etc/ssh/sshd_config\n\
echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
/usr/sbin/sshd\n\
echo \"SSH started - Login: \$USERNAME (root disabled)\"\n\
" /root/entrypoint.sh && docker restart CONTAINER_NAME
'

Example with real values:

  docker exec casaos bash -c '
  USERNAME="alice" && \
  PASSWORD="secret123" && \
  grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
  # Auto-start SSH - Custom User Only\n\
  USERNAME=\"$USERNAME\"\n\
  PASSWORD=\"$PASSWORD\"\n\
  id \"\$USERNAME\" >/dev/null 2>\&1 || useradd -m -s /bin/bash \"\$USERNAME\"\n\
  echo \"\$USERNAME:\$PASSWORD\" | chpasswd\n\
  mkdir -p /run/sshd\n\
  sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
  sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
  echo \"PermitRootLogin no\" >> /etc/ssh/sshd_config\n\
  echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
  /usr/sbin/sshd\n\
  echo \"SSH started - Login: \$USERNAME (root disabled)\"\n\
  " /root/entrypoint.sh && docker restart casaos
  '

After running, login with:

Username: alice (your custom username)
Password: secret123 (your custom password)
Port: 22

---

Option 2: Custom User + Root Access ⭐⭐⭐

What this does:

✅ Creates YOUR custom username and password
✅ ALSO allows root login (less secure but flexible)
✅ You can login as either your user OR root
✅ SSH starts automatically every time container restarts

Instructions:

Replace these before running:

• CONTAINER_NAME = your Docker container name (example: casaos)
• YOUR_USERNAME = your desired SSH username (example: bob)
• YOUR_PASSWORD = your desired SSH password (example: mypass456)
• ROOT_PASSWORD = password for root user (commonly: casaos)

Command:

  docker exec CONTAINER_NAME bash -c '
  USERNAME="YOUR_USERNAME" && \
  PASSWORD="YOUR_PASSWORD" && \
  ROOT_PASSWORD="ROOT_PASSWORD" && \
  grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
  # Auto-start SSH - Custom User + Root\n\
  USERNAME=\"$USERNAME\"\n\
  PASSWORD=\"$PASSWORD\"\n\
  ROOT_PASSWORD=\"$ROOT_PASSWORD\"\n\
  id \"\$USERNAME\" >/dev/null 2>\&1 || useradd -m -s /bin/bash \"\$USERNAME\"\n\
  echo \"\$USERNAME:\$PASSWORD\" | chpasswd\n\
  echo \"root:\$ROOT_PASSWORD\" | chpasswd\n\
  mkdir -p /run/sshd\n\
  sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
  sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
  echo \"PermitRootLogin yes\" >> /etc/ssh/sshd_config\n\
  echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
  /usr/sbin/sshd\n\
  echo \"SSH started - Login: \$USERNAME or root\"\n\
  " /root/entrypoint.sh && docker restart CONTAINER_NAME
  '

Example with real values:

  docker exec casaos bash -c '
  USERNAME="bob" && \
  PASSWORD="mypass456" && \
  ROOT_PASSWORD="casaos" && \
  grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
  # Auto-start SSH - Custom User + Root\n\
  USERNAME=\"$USERNAME\"\n\
  PASSWORD=\"$PASSWORD\"\n\
  ROOT_PASSWORD=\"$ROOT_PASSWORD\"\n\
  id \"\$USERNAME\" >/dev/null 2>\&1 || useradd -m -s /bin/bash \"\$USERNAME\"\n\
  echo \"\$USERNAME:\$PASSWORD\" | chpasswd\n\
  echo \"root:\$ROOT_PASSWORD\" | chpasswd\n\
  mkdir -p /run/sshd\n\
  sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
  sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
  echo \"PermitRootLogin yes\" >> /etc/ssh/sshd_config\n\
  echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
  /usr/sbin/sshd\n\
  echo \"SSH started - Login: \$USERNAME or root\"\n\
  " /root/entrypoint.sh && docker restart casaos
  '

After running, login with EITHER:

Custom User: bob / mypass456
OR
Root User: root / casaos
Port: 22

---

Option 3: Root Only (Simplest) ⭐⭐

What this does:

✅ Only allows root login (simplest but least secure)
✅ Uses password "casaos" for root (standard default)
✅ SSH starts automatically every time container restarts
✅ Good for testing or personal use

Instructions:

Replace these before running:

• CONTAINER_NAME = your Docker container name (example: casaos)
• ROOT_PASSWORD = password for root user (example: casaos)

Command:

  docker exec CONTAINER_NAME bash -c '
  ROOT_PASSWORD="ROOT_PASSWORD" && \
  grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
  # Auto-start SSH - Root Only\n\
  ROOT_PASSWORD=\"$ROOT_PASSWORD\"\n\
  echo \"root:\$ROOT_PASSWORD\" | chpasswd\n\
  mkdir -p /run/sshd\n\
  sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
  sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
  echo \"PermitRootLogin yes\" >> /etc/ssh/sshd_config\n\
  echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
  /usr/sbin/sshd\n\
  echo \"SSH started - Login: root\"\n\
  " /root/entrypoint.sh && docker restart CONTAINER_NAME
  '

Example with real values:

  docker exec casaos bash -c '
  ROOT_PASSWORD="casaos" && \
  grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i \
  # Auto-start SSH - Root Only\n\
  ROOT_PASSWORD=\"$ROOT_PASSWORD\"\n\
  echo \"root:\$ROOT_PASSWORD\" | chpasswd\n\
  mkdir -p /run/sshd\n\
  sed -i \"/PermitRootLogin/d\" /etc/ssh/sshd_config\n\
  sed -i \"/PasswordAuthentication/d\" /etc/ssh/sshd_config\n\
  echo \"PermitRootLogin yes\" >> /etc/ssh/sshd_config\n\
  echo \"PasswordAuthentication yes\" >> /etc/ssh/sshd_config\n\
  /usr/sbin/sshd\n\
  echo \"SSH started - Login: root\"\n\
  " /root/entrypoint.sh && docker restart casaos
  '

After running, login with:

Username: root
Password: casaos
Port: 22

📖 What Each Part Does

Line-by-line explanation:

docker exec CONTAINER_NAME bash -c '
→ Run commands inside the Docker container

USERNAME="YOUR_USERNAME" &&
PASSWORD="YOUR_PASSWORD" &&
→ Set your desired username and password (replace with your values)

grep -q "Auto-start SSH" /root/entrypoint.sh || sed -i "/^tail -f/i
→ Check if SSH auto-start is already installed. If not, add it to the startup script

id "$USERNAME" >/dev/null 2>&1 || useradd -m -s /bin/bash "$USERNAME"\n
→ Check if user exists. If not, create user with home directory and bash shell

echo "$USERNAME:$PASSWORD" | chpasswd\n
→ Set (or update) the password for the user

mkdir -p /run/sshd\n
→ Create the directory that SSH daemon needs to run

sed -i "/PermitRootLogin/d" /etc/ssh/sshd_config\n
sed -i "/PasswordAuthentication/d" /etc/ssh/sshd_config\n
→ Remove any old SSH configuration settings to avoid duplicates

echo "PermitRootLogin no" >> /etc/ssh/sshd_config\n
→ Disable root login (change to "yes" to allow root)

echo "PasswordAuthentication yes" >> /etc/ssh/sshd_config\n
→ Enable password-based authentication (required for login)

/usr/sbin/sshd\n
→ Start the SSH server daemon

" /root/entrypoint.sh && docker restart CONTAINER_NAME
→ Save all changes to the startup script, then restart the container to apply them

❓ Troubleshooting

Q: How do I find my container name?

docker ps
Look for the container with image dockurr/casa

Q: The command says "permission denied"

• Make sure you're running with proper permissions
• Try adding sudo before the command if on Linux

Q: SSH still not working after restart

• Wait 10-15 seconds after restart for all services to start
• Check if SSH is running: docker exec casaos ps aux | grep sshd

Q: I want to change my password later

Just run the command again with the new password - it will update it

Q: Can I remove SSH auto-start?

docker exec casaos sed -i '/# Auto-start SSH/,/echo "SSH started/d' /root/entrypoint.sh
docker restart casaos
