roles/common: Add support for fail2ban 
This is active banning of IPs that are brute forcing login attempts
to SSH, versus the passive banning of 10,000 abusive IPs from the
abuseipdb.com blacklist. For now I am banning IPs that fail to log
in successfully more than twelve times in a one-hour period, but
these settings might change, and I can override them at the group
and host level if needed.

Currently this works for CentOS 7, Ubuntu 16.04, and Ubuntu 18.04,
with minor differences in the systemd configuration due to older
versions on some distributions.

You can see the status of the jail like this:

    # fail2ban-client status sshd
    Status for the jail: sshd
    |- Filter
    |  |- Currently failed: 0
    |  |- Total failed:     0
    |  `- Journal matches:  _SYSTEMD_UNIT=sshd.service + _COMM=sshd
    `- Actions
       |- Currently banned: 1
       |- Total banned:     1
       `- Banned IP list:   106.13.112.20

You can unban IPs like this:

    # fail2ban-client set sshd unbanip 106.13.112.20

Ansible Playbook

Ansible playbook for base and initial configuration of the web server hosting my personal websites. After successful execution of this playbook, however, there is still some manual work to import databases, copy site content, etc.

Assumptions

Before you can run this, a few things are assumed:

  • You have a clean, minimal Debian 9, Ubuntu 16.04, Ubuntu 18.04, or Debian 10 host up and running
  • Python 2 or 3 is installed on the remote server (requirement of Ansible)
  • You have a user account with password-less SSH access to the machine
  • You have sudo privileges on the remote host
  • You have created a hosts file with something like:
[web]
web01

Use

Once you've satisfied the the above assumptions, you can execute:

$ ansible-playbook web.yml
