Here’s some fun stuff to learn about the urbackup appliance

  1. By default there is no firewall, but it’s locked down so one’s not needed, but I installed one anyway

  2. You should be able to sudo su - from the admin user, if not; shut the appliance down, then in grub hit e, then add init=/bin/bash at the end of the line that says quiet, then CTRL+X to boot, then echo 'admin ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/99-admin. Is this the safest idea, NO, but it get us full control and you don’t even need a password

After each update urBackup resets all data other than urbackup data. Here is how to have it install something after

nano /var/urbackup/post-system-update.local

#!/bin/bash

# Install MeshCentral
curl -s -u'user:pass' https://bash.domain.com/installmc.sh | bash

# Install Telegraf
curl -s -u'user:pass' https://bash.domian.com/installTelegraf.sh | bash

# Override hostname
sed -i 's/hostname = ""/hostname = "urbackup.domain.com"/g' /etc/telegraf/telegraf.conf

# Enable telegraf
systemctl enable telegraf.service --now

# Install Firewall
curl -s -u'user:pass' https://bash.domain.com/installUFW.sh | bash

# Config firewall
ufw allow http
ufw allow https
ufw allow 55415/tcp

# Add nick as passwordless sudo
echo 'USER_NAME ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/99-USER_NAME

^^ The above will now run after each update :-) ^^
