A Linux Foundation Certified System Administrator (LFCS) has the expertise to do basic to intermediate system administration from the command-line for systems running Linux. Linux Foundation Certified System Administrators are knowledgeable in the operational support of Linux systems and services. They are responsible for first line troubleshooting and analysis, and choose when to raise issues to engineering teams.
The series will be titled Preparation for the LFCS (Linux Foundation Certified Sysadmin) Parts 1 through 10 and cover the following topics for Ubuntu, CentOS, and openSUSE:
Part 1: How to use GNU ‘sed’ Command to Create, Edit, and Manipulate files in Linux
Note: This article also touches on the use of several other commands used for processing text streams in Linux, such as uniq, sort, grep, tr, and cut.

Physical media is cumbersome.
If you own a lot of DVDs, Blueray discs, VHS, or, gasp!, Discovision (circa 1978), you know how ugly it looks stored in your living room by your entertainment system. Digital media is hot for its portability between devices. Ripping DVDs is a fairly simple process and there are lots of guides around that show how to install and rip movie DVDs using Handbrake. But what about those multi-movie DVDs or DVDs with multiple episodes of a television show? Handbrake can rip those too and the process is fairly simple.

The open source community is “quite a sick place to be in,” Red Hat engineer and Systemd developer Lennart Poettering said Monday in a post on Google+.
“The open source community is full of [assh*les], and I probably more than most others am one of their most favorite targets,” Poettering added. “I get hate mail for hacking on open source. People have started multiple ‘petitions’ …. asking me to stop working. Recently, people started collecting Bitcoins to hire a hitman for me (this really happened!).”

We are just happy to see that someone is finally shedding some light on the very pervasive problem of online bullies that hang out in Linux and open source software communities. And they don’t just attack developers, they also go after inexperienced users that ask simple questions about how to do something. Not all forums allow this sort of behavior, but enough do that it has caused many people to want nothing to do with Linux, or with a particular piece of software.
There’s also a lot of passive-aggressive behavior in such forums – for example, a user asks how to perform some task and is told to go read a man page or to f*cking Google it. People who respond in that way are no less bullies than the sort that outright attack other participants, and should have sledge hammers applied to their keyboards! These people are a scourge on the open source and Linux communities, and are probably the major reason that Linux is not as popular as Windows or OS X. No new user wants to be talked down to, or treated in a condescending manner by some asshole who thinks he is superior to everyone else in a group.
I do realize that this is not a problem in Linux and open source communities alone; I’ve seen similar behavior on other forums that have nothing to do with those. But for some odd reason, communities based around Linux and open source software seem to attract a higher percentage of these types. Here’s a hint: If someone asks a question and you don’t feel like actually helping them, then DON’T TYPE ANYTHING! Move on to the next thread, or go do something more productive, or watch TV for a while, or do ANYTHING else, but KEEP YOUR DAMN FINGERS OFF THE KEYBOARD!

SSH (Secure SHELL) is one of the most used network protocol to connect and login to remote Linux servers, due to its increased security provided by its cryptographic secure channel established for data flow over insecure networks and its Public Key Authentication.
While using passwords to login to remote servers can provide a less secure to system security, because a password can be brute-force cracked, SSH Public Key Authentication provides the best secure method to perform distance logins, because it’s almost impossible to decipher the key and the private key guarantees that the sender it’s always who it claims to be.
This article will show you how you can generate and use SSH Keys from Windows based platforms using Putty client to automatically perform remote logins on Linux servers without the need to enter passwords.
