The default in later OpenSSH is 6, which seems too high. If you can't
get your password correct after 3 tries then I think you need help.
Eventually I'd like an easy way to enable blocking of repeated login
attempts at the firewall level. I think it's possible in firewalld.
Harder to run one of these than I thought. Mostly it takes a lot of
bandwidth, and it's probably better to spend the $5/month you'd sp-
end on the VPS by donating $50 to the torservers.net project.
Avoids the following error in apt:
Skipping acquire of configured file 'nginx/binary-i386/Packages' as repository 'https://nginx.org/packages/ubuntu bionic InRelease' doesn't support architecture 'i386'
There are several ways to install external roles, ie via ansible-galaxy,
git submodules, etc. I found that adding this role to a requirements.yml
file and adding instructions to the README.md is probably the best way.
Using ansible-galaxy actually had issues because the ansible-relayor git
repository has version tags that use mixed styles, like v0.3.3 and 0.1.0
without a v.
No need to give Google even more data or free advertising by using
this as the default! In practice I always use the DNS servers from
the VPS provider anyways.
Instead of looping over a list of items to install, we can actually
just give a list directly to the apt module. This allows the module
to install all packages in one transaction, which is faster as well
as slightly safer for some dependency resolution scenarios.
This tag is no longer reachable after switching to the new dynamic
includes in Ansible 2.4 and 2.5. Anyways, I've been questioning my
decision to add the "packages" tag to any task that uses the apt
module.

Because of the shift from static imports to dynamic includes these
tags will never be reached unless they have their own task that is
tagged at the top-level (dynamic includes don't pass their tags to
their children).
After reörganizing for dynamic includes these tags will never be reached
because the children of dynamic includes do not inherit tags from their
parents as they did with static imports.
As of Ansible 2.4 and 2.5 the behavior for importing tasks has changed
to introduce the notion of static imports and dynamic includes. If the
tasks doing the import is using variable interpolation or conditionals
then the task should be dynamic. This results in quicker playbook runs
due to less importing of unneccessary tasks.
One side effect of this is that child tasks of dynamic includes do not
inherit their parents' tags so you must tag them explicitly or a block.
Also, I had to move the letsencrypt tasks to the main task file so the
tags were available (due to dynamic tasks not inheriting tags).
