sshI use ssh connections to manage remote servers it’s one of the main task in my work, so over time I’ve learnt some tricks to speed up the connection phase of the ssh protocol, so in this article I’ll show you how to:

Configure ssh to use ipv4 only
Configure ssh to use a particular authentication method
Reuse SSH Connection
Disable the Dns lookup on server side

Also if you are interested in ssh you can take a look at my previous articles about How to keep ssh connections alive on Linux and how to keep a Permanent SSH Tunnels with autossh.

If you do a lot of typing it could be useful to have a program that can easily manage your custom shortcuts, create and test them.

For all these things you can use the program autokey.

AutoKey is a desktop automation utility for Linux and X11. It allows you to manage collection of scripts and phrases, and assign abbreviations and hotkeys to these. This allows you to execute a script or insert text on demand in whatever program you are using.

AutoKey features a subset of the capabilities of the popular Windows-based AutoHotkey, but is not intended as a full replacement. For a Linux-based implementation of AutoHotkey, see IronAHK. AutoKey’s GUI features a number of concepts and features inspired by the Windows program PhraseExpress.

attackArticle by Chris Pentago

DDoS attacks (Distributed Denial-of-Service attacks) have been a global Internet phenomenon and a problem for quite some time now. Ever since the Internet started being used for making money and for generating large amounts of revenue, there have been people who have been trying (for whatever purpose) to bring down these webpages.

These attacks have a final goal of stopping the functioning of a website, which will, in turn, make it inaccessible for everyone on the Internet. Website downtime can, as I mentioned, bring about substantial losses of revenue, which is why these attacks have to be stopped at all costs.

Now, when it comes to the targets for these attacks, they are usually websites of some high-profile companies and businesses, as well as important government agencies. They target the websites that are hosted on major web hosting providers, ensuring that these pages stay down for a couple of hours.

If the problem is not dealt with, or is dealt with poorly, then the downtime can be prolonged indefinitely and can, after a while, cause the owner of the website (be it a business, a government agency or anything else) to break, usually financially.

Article from Tcat Houser editor-in-chief of TRCBNews.com.

Philosophies on how to approach things in life, for example Open Source Versus Closed, run in cycles. In the 1970s hobbyists would be carefully typing BASIC code from there enthusiast magazine. Commodore, Apple or the highest podge of C/PM machines.

Open Source went out of fashion (relatively speaking) with the emergence of DOS and Microsoft. In terms of absolute numbers, Open Source actually grew. It was the relative percentage in the overall digital world with major players doing proprietary code that made it look like Open Source was old-fashioned.

Coinciding with Microsoft starting several years of development work on ‘Chicago’ (Windows 95) Linux started to gain some real traction in the shadows. In my opinion this is only because the attempts to create (again) a Unified UNIX in the late 1980s failed (again).

We find ourselves where we are today because there are two types of computer users. Some of us like the joy of figuring something out, while others merely see it as something to get something else done. There are a few of us that do the former to help the latter. I’m one of those few.

I am keenly aware of the fact that readers here are solidly in the former camp and do not understand those in the latter camp.
