People might manually change critical config files in servers occasionally. For example, /etc/hosts, /etc/hostname, etc.
As an experienced operator, you will remember to backup, before making any changes. Right? What would you do? cp /etc/hosts /etc/hosts.bak.
But is that good enough?
As DevOps or IT professionals, people may ask us why they can’t ssh to servers. It happens from time to time. Isn’t right? Not much fun. Just routine work.
Want to ease the pain and burden? Let’s examine common ssh failures together. Next time forward this link to your colleagues, if useful. People may be able to identify the root cause all by themselves, or be efficient in collecting all necessary information, before turning to us.
Using a single command, we can easily upload any files from our computers or servers to a web server. Then our friends or colleagues can download them directly from web browsers. Isn’t that cool?
Worry about the security? We can encrypt files before transfer. Also we can claim the maxinum downloads of those files, or expire download link in several days.
Here we go! transfer.sh: easy and fast file sharing from the command-line. Zero Initial Setup and Super Easy to use.
For DevOps, installation is one of our major tasks. People may wonder package installation is pretty straight-forward and easy now. Just run commands like apt-get, yum, brew, etc. Or simply leave it to containers.
Is it really that easy? Here is a list of headache and hidden costs. Discuss with us, DevOps gurus!
