• University of Toronto ☛ There are at least two ways to 'verify' TLS client host certificates

In private deployments, these client certificates are often issued out of a private Certificate Authority, possibly with custom fields that are understood by the software involved. However, you can also use conventional public TLS certificates for hosts as client certificates, and there are situations where you might want to do this; for a non-hypothetical example, you might want to verify some sort of 'identity' of third party SMTP mail sending machines that are contacting your (public) SMTP server in order to give them extra privileges.

  Manually adjusting your CPU fan speeds is a great way to prioritize benefits like quietness or cooling by your preferences. The best part is that you can easily accomplish this on your Linux system with the help of fancontrol or other fan speed control applications.
