A vim plugin manager is a must for any die-hard vim user. You can find a few option available out there. My personal favorite is vim-plug which is a beautiful and minimalist plugin for vim. Let us see how to install and use this plugin on Linux or Unix-like system.
Coreboot is a free and open source software. The project aimed at replacing the proprietary BIOS firmware and blobs. Unfortunately, Coreboot does not run on the modern laptop (except Chromebooks) due to Intel ME and other closed source technologies.
Purism vendor sells Linux preloaded on the Librem 13 and the Librem 15 laptops. Purism claims to follow a strict belief in users’ rights to privacy, security, and freedom. Untile today Librem bios was not freed. However, the coreboot port for the Librem 13 v1 is 100% done. It means you can have blob free Coreboot running on a full-fledged modern laptop. The laptop comes with Hardware Kill Switches that physically sever the circuit at the hardware level for Wireless & Bluetooth, Camera & Microphone. The specs are as follows:
Recently I come across a nice little nifty tool called pssh to run a single command on multiple Linux / UNIX / BSD servers. You can easily increase your productivy with this SSH tool.
More about pssh
pssh is a command line tool for executing ssh in parallel on some hosts. It provides specialties includes:
- Sending input to all of the processes
- Inputting a password to ssh
- Saving output to files
- IT/sysadmin taks automation such as patching servers
- Timing out and more
Let us see how to install and use pssh on Linux and Unix-like system.
Build automation is a vital tool for devops, sysadmins, and developers. It is nothing but scripting or automating the process of compiling source code into binary. Sysadmins can use build tools to manage and update config files. Following is a list of awesome open source and popular tools associated with automating build processes on Linux or Unix-like system.
Oops! I did it again. I thought I was logged into my home server. Turns out I rebooted the db server. Another my not so favorite is typing "shutdown -h 0" into the wrong terminal. I know a few people who have admitted to doing that here.
Is there any end to the madness? Do I need to suffer from accidentally random reboots and shutdowns? After all, it is human nature to make mistakes, but one should not keep on making the same mistakes again and again.
Intel's Atom C2000 chips are bricking products, and it’s not just Cisco hit. From the theregister:
Intel's Atom C2000 processor family has a fault that effectively bricks devices, costing the company a significant amount of money to correct. But the semiconductor giant won't disclose precisely how many chips are affected nor which products are at risk. Coincidentally, Cisco last week issued an advisory warning that several of its routing, optical networking, security and switch products sold prior to November 16, 2016 contain a faulty clock component that is likely to fail at an accelerated rate after 18 months of operation.
Intel has "Silvermont" which is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. It includes:
- Avoton – SoCs for micro-servers and storage devices.
- Rangeley – SoCs targeting network and communication infrastructure.
Recently I came across an excellent software called CoreFreq. It is a CPU monitoring software designed for 64-bits Processors w/ architectures Intel Atom, Core2, Nehalem, SandyBridge and superior, and AMD Family 0F. It runs on 64 bit Linux system. CoreFreq provides a framework to retrieve CPU data with a high degree of precision:
For some weird reason, I can not get my OpenVPN server to come up at boot time using systemd on an Ubuntu Linux 16.04 LTS server. I have tried a few settings but failed so far.
Do you find my tutorials and nixcraft ( https://www.cyberciti.biz/ ) site useful? Please consider supporting it especially if you use ad-blocker. It is hard to keep the site running when so many people block ads. nixCraft is a single man indie operation and online since 2002. I had started this site for sharing my knowledge and documenting my experience as a sysadmin. Over last 15 years site grown a lot. I was able to fund nixCraft for a while with my job and savings.
I have written about Linux, Unix, FreeBSD, OpenBSD, Sysadmin and FOSS-related tutorials for many years. I have written over 5100+ tutorials and long blog posts. Apart from posts, I regularly reply tech support emails and moderate comments here. nixCraft has become a 40+ hour/week job for me. I want to nixCraft to grown more for a long time. It is time to see if it is possible to be a self-employed writer in the open source and Linux. By supporting me, you are going to keep the www.cyberciti.biz website alive.
You can choose from several options to support nixCraft:
- Patreon (Recommended option and you can pledge any amount you want from $1 to $as_per_your_wish)
- PayPal (one time donation)
- Bitcoin address: 1F8jsWqRuhND7LgmJ9F7QzwPBp4PS2tkRR
I am sure most *nix sysadmins or Linux user were helped at least once or many times by my nixCraft (https://www.cyberciti.biz). I needs your support, too. Thanks for any help you can offer if you decide to, and thanks for being a reader!
