You can reuse OpenSSH connections to the same server when you want to open subsequent connections to the same server. For example, if I ran ssh [email protected], the ssh client will establish a new SSH connection. It usually takes only a few seconds. However, if I run ssh [email protected] command again, connecting to a server42.cyberciti.biz multiple times result into the overhead.
This tutorial talks about ssh features called multiplexing that reuse an already-established connection when creating a new SSH session.
Well, that was fast. Touch ID is a fingerprint recognition security feature, designed and released by Apple. It is currently available on the iPhone 5s/6/7 and Macbook pro-2016 editions. Many consider it as a huge security win for the MacBook Pro’s. This sounds amazing feature for command line users.
Say hello to sudo-touchid
sudo-touchid is a fork of sudo with Touch ID support on macOS (powered by the LocalAuthentication framework). Once compiled, it will allow you to authenticate sudo commands with Touch ID in the Terminal on supported Macs (such as the late 2016 MacBook Pros). Since Darwin sources for macOS 10.12 are not available yet, this project is based on sudo sources corresponding to OS X 10.11.6 and obtained from opensource.apple.com.

It’s always a good idea to keep backups of all of your data in multiple places. Every Linux or Unix sysadmin must master the art of backups if you want to keep your data forever. Most sysadmin recommend and follows the 3-2-1 rule:
- At least three copies of data.
- In two different formats.
- With one of those copies off-site.
Tarsnap is one of such off-site backup sites. It’s a secure online backup system for UNIX-like system. This service encrypts and stores data in Amazon S3. To use Tarsnap perfectly and feel secure about your backups, you need the “Tarsnap Mastery” book by Michael W. Lucas. It is no secret that I’m a big fan of his book series. Let’s see what the book is all about.
