Adding OpenSSH Support to UrBackup Restore CD

Restore

Hey guys just wanted to show you a small thing i made regarding restore cd which might help some people. If you’re using the UrBackup Restore CD and need SSH access for remote management, you can modify the build process to include openssh-server and enable SSH at boot. Below is a guide to integrating this feature into the build_image.sh script.

For now this is not 100% secure because root and password are plaintext this could be done maybe with some ssh keys or something if anyone has any ideas that can add to this is more than welcomed.

#!/bin/bash

set -e

./create_splash.sh
cd image_root

# Step 1: Clean up any previous live build data
lb clean

# Step 2: Create the package list to include openssh-server
mkdir -p config/package-lists
echo "openssh-server" > config/package-lists/my-packages.list.chroot

# Step 3: Create a hook to enable and start SSH at boot
mkdir -p config/hooks/live
cat <<'EOF' > config/hooks/live/0300-enable-ssh.hook.chroot
#!/bin/bash
# Enable the ssh service
systemctl enable ssh
# Set username and password
echo "ROOT_USERNAME:PASSWORD" | chpasswd
# Allow root login and password authentication (adjust sshd_config to permit root login)
sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
sed -i 's/#PasswordAuthentication yes/PasswordAuthentication yes/' /etc/ssh/sshd_config
EOF
chmod +x config/hooks/live/0300-enable-ssh.hook.chroot

# Step 4: Configure the build process with the required parameters
lb config --apt apt --apt-recommends false --tasksel none --apt-indices false \
          --distribution bookworm --memtest none \
          --mirror-binary http://ftp.uni-stuttgart.de/debian/ \
          --mirror-bootstrap http://ftp.uni-stuttgart.de/debian/ \
          --architectures amd64 \
          --mirror-chroot http://ftp.uni-stuttgart.de/debian/ \
          --linux-flavours "amd64" --debian-installer false \
          --firmware-binary true --system live --compression xz \
          --bootappend-live "boot=live components username=urbackup" \
          --iso-application "UrBackup Restore" \
          --iso-preparer="Martin Raiber <martin@urbackup.org>" \
          --iso-publisher="Martin Raiber <martin@urbackup.org>" \
          --zsync false --iso-volume "UrBackup Restore" \
          --archive-areas "main contrib non-free non-free-firmware" \
          --parent-archive-areas "main contrib non-free non-free-firmware" \
          --parent-distribution bookworm --initsystem systemd \
          --firmware-chroot true --security false

# Step 5: Build the image
lb build
