The SSH keepalive value determines how often an idle SSH connection will send a message to the remote host to keep the connection alive. If the connection is idle for longer than the keepalive value, the connection will be closed.

To prevent Ansible from hanging due to idle SSH connections, it is recommended to set an appropriate SSH keepalive value. A common value for this parameter is 60 seconds. This value can be set in the ssh_args parameter in your Ansible inventory file, like this:

ansible_ssh_common_args='-o ServerAliveInterval=60'

Alternatively, you can set this value in your SSH configuration file (~/.ssh/config) using the following syntax:

Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

• at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
• check nginx -V for the following:

  ...
  TLS SNI support enabled

FreeNAS

This page is constantly being edited and worked on. Most of these should work but some might be broken.

Here are straight-forward instructions to setting up a bunch of different software on FreeNAS. If you make a terrible error, just throw up another plugin sandbox and repeat.
