Use ssh certificates to set up a forced command for a simple server monitoring with one-year validity.
# Create the "certification authority". The private key of CA does not have to (and must not) be copied anywhere.
user@home$ ssh-keygen /home/user/.ssh/certification_authority
# Make CA public key trusted on a server.
user@home$ scp /home/user/.ssh/certification_authority.pub root@server:
root@server# cd; (echo -n "cert-authority "; cat certification_authority.pub ) >> .ssh/authorized_keys
# Generate a certificate for any command you can think of
# Example -- command: "tailf /var/log/messages" validity: 52 weeks from now Permissions: none (no forwarding etc.)
user@home$ ssh-keygen -f tailfmessages.key

Global gitignore

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file:

  • Create a file called .gitignore in your home directory and add any filepath patterns you want to ignore.
  • Tell git where your global gitignore file is.

Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute .config/git/ignore for .gitignore in your home directory, if you prefer.

Get OS version for an inventory with ad-hoc ansible
# The setup command allows filtering facts
# More info: https://docs.ansible.com/ansible/latest/modules/setup_module.html
# inventory_file = path to inventory file (if not normal role layout)
# host_group = group to query. use all for all hosts
ansible -i inventory_file host_group -m setup -a 'filter=ansible_distribution_version'
# For a Ubuntu Bionic Host the distribution facts look like this:
# "ansible_distribution": "Ubuntu",
# "ansible_distribution_file_parsed": true,
# "ansible_distribution_file_path": "/etc/os-release",
