Systemd
Article by Stuart Burns first posted on Openlogic.com

With Red Hat Enterprise Linux 7 released and CentOS version 7 newly unveiled, now is a good time to cover systemd, the replacement for legacy System V (SysV) startup scripts and runlevels. Red Hat-based distributions are migrating to systemd because it provides more efficient ways of managing services and quicker startup times. With systemd there are fewer files to edit, and all the services are compartmentalized and stand separate from each other. This means that should you screw up one config file, it won’t automatically take out other services.

Systemd has been the default system and services manager in Red Hat Fedora since the release of Fedora 15, so it is extensively field-tested. It provides more consistency and troubleshooting ability than SysV – for instance, it will report if a service has failed, is suspended, or is in error. Perhaps the biggest reason for the move to systemd is that it allows multiple services to start up at the same time, in parallel, making machine boot times quicker than they would be with legacy runlevels.

Modern day criminals are no longer entering banks with ski masks and pistols. Today’s felons are moving into cyberspace to accomplish their nefarious goals.

Remember the old adage, “a criminal always returns to the scene of the crime”? It turns out this maxim holds a lot of weight with regards to DDoS cybercrime.

Double DDoS

Recent research from BT revealed that about 41% of online businesses surveyed were victims of DDoS in the last 12 months. The more notable findings of the research showed that, of those attacked, over 78 percent were subsequently hit a second time shortly thereafter.

Distributed Denial of Service attacks or DDoS encompass a large variety of cyber threats designed to overwhelm a target’s server, or jam up their network. By disrupting a target’s resources, the hackers succeed in preventing normal traffic (such as users or customers) from passing through.

The effects of these attacks are potentially devastating. After being hit by a strong attack, it takes on average at least 12 hours to offer full service back to users.

What can happen in 12 hours? This sort of disruption could mean losing hundreds of thousands of dollars in revenue. Or, perhaps worse, the trust between the user and the online business, built up over months or years, could be lost in a matter of minutes.

Some time ago I posted an article about shelr.tv a website and a service that was made to allow you to share your terminal records directly from the website.

Now the website of shelr.tv seems dead and so I’ve took a look around to see if there are similar websites and I’ve found commands.com.

For what I can see from their homepage it’s a service similar to the other, so let’s test it.

LinuxAIOSometimes you want to test or show different GNU/Linux distributions, or just different desktop environment, and in these cases you usually have to put different ISO on CD/DVD or better on USB Sticks and this usually take some time. Luckily now there is a new and nice project that makes the work of testing different distributions much more easy: the Linux AIO (All In One) project.

From the Linux AIO website:

Our plan is to bring some of the major Linux distributions (Ubuntu and flavors, Linux Mint (“Debian”), Debian Live) with different desktop environments on one ISO file that can be burnt on one DVD or USB flash drive. Every one of them can be used as Live system, with no need of installation on hard drive or can be eventually installed on computer for full experience.

First of all, Zorin team, Linux notes from DarkDuck and Linuxaria would like to say THANK YOU to all the participants of the contest that we ran for last few weeks. It was a real pleasure to see such a response, and to read all your article. As you probably know the winner have been announced in another post and today I want to publish some of the best articles that we’ve received.

So have fun in reading these article of other Linux users.
