    This is a case where the time from when I took it to when it was resolved happened to be about half an hour. Being half an hour late might not mean a lot to some people, but computer systems are much more sensitive to time and need it to be accurate and synchronized. That’s why it’s crucial to have a solid NTP (Network Time Protocol) infrastructure. This case shows how important attention to detail can be when troubleshooting a system.

  • Looking at the outlying data points

    The solution was great: they came up with something that looked like a server for airflow purposes, but which didn't actually do anything. It was basically two very big paperboard pizza boxes side by side. They would then slip that into the rack right below the last server, or any time they pulled one from somewhere higher in the stack. This would keep the airflow doing its thing happily for whatever was right above it.

    This rolled out and my hot spots disappeared. Fantastic!

    Before you learn about Zombie process, let me recall what is a process in Linux.

    In a few words, a process is a running instance of a program in performance. It can be foreground (interactive process) or background (not interactive or automatic process). It can be a parent (creator of other processes during run-time) or child (process created by others) process.

    In Linux, except for the first init (or systemd) process with PID 0, every other process has a parent process. Processes also have their own child processes.

    Don’t believe me? Use the pstree command in terminal to look at the process tree to see the ‘family tree’ of your system’s processes.

  • How to check your CPU in a Linux system

    To troubleshoot or build a software stack, you must not only know what type of architecture you work with, but also the details about your hardware and its performance. When it comes to Linux, you can gather that information via the command-line interface. The Linux CLI can provide you with detailed CPU information, such as the number of CPU cores, CPU architecture and CPU usage.

    You can use several specific commands to pull CPU information from your hardware, regardless of whether you use bare metal or virtualized hardware. These commands should work on any Linux distribution and should come preinstalled on your systems.

  • How to manage users and groups in Linux | Enable Sysadmin

    "What skills must Linux administrators have?" is way too broad a question for any single article. But there are plenty of general must-have sysadmin skills—and user and group administration are chief among them. Proper user account management enables Linux to enforce access controls (permissions) and audit who does what on the system.

    The commands below are written for Red Hat Enterprise Linux (RHEL) and RHEL-like distributions, but the concepts apply to any distribution of Linux. Knowing the skills and commands outlined in this article (and its two follow-up pieces, which dive deeper into user admin and group admin) helps ensure you're ready for the day-to-day user and group administration tasks a sysadmin is called on to do.

  • How to use PS command - Unixcop

    Using a system without monitoring what’s happening in the background is not a good thing to do -especially in Linux- because as a result, you may be consuming resources in the wrong side of the city, or your system may be not properly utilized in the manner way.

  • File timestamps in Linux - atime, mtime and ctime

    In the Linux system, the system provides a file with three timestamps, namely access timestamp (atime), change timestamp (mtime), and change timestamp (ctime). Linux stores the timestamp in the Unix epoch instead of the actual date and time. The Unix epoch is the number of seconds from 00:00:00 on January 1, 1970.

    This article will help you understand Linux file timestamps and how file timestamps work. I have used for all the examples in this article an Ubuntu 20.04 system. Let's first discuss the definition and how we can display it in our Linux system.
