Author: Bill Toulas •
Tags: centos, debian, linux, opensuse, security, ubuntu •
Comments: 1 Steganography is the ancient art of the information concealment. People have found numerous methods to achieve this such as “invisible” inks, messages hidden in objects, and the famous “null cipher”. The word “steganography” comes from the Greek words “steganos” and “graphy” which means “impenetrable writing”. The years have passed and steganography has evolved into a sophisticated part of cryptography.

How to Detect Network Devices with Python on Linux
Author: David Duarte •
Tags: centos, linux, programming •
Comments: 0 Sometimes you might have network or firewall issues in an internal that require a network scan to find which IP addresses are in use. For that purpose, we can use ready-made tools such as nmap, zmap or angryIP. But if we have no internet access to download these tools we can do the scan by only using manual commands. However, the manual scanning can be quite tedious, with the understanding that should be done for each IP address given on our network.

Server monitoring with Munin and Monit on CentOS 7
Author: Till Brehm •
Tags: centos, monitoring, security •
Comments: 2 In this article, I will describe how you can monitor your CentOS 7 server with Munin and Monit. Munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas Monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Tags: centos, debian, desktop, fedora, linux, suse, ubuntu •
Comments: 1 Fritzing is a new open source PCB designer that supports Linux systems. Its power stems from its user-friendly interface, drag n drop features, pleasing visuals, and comprehensive views. To me, it looks very much like Autodesk's 123D Circuits and also works very similarly to it too, so this is very positive to say the least.

Tags: centos, debian, desktop, fedora, linux, opensuse, ubuntu •
Comments: 0 Almost every modern digital camera offers the ability of “on the fly” panorama creation, but often you will find the result of this automated process not to meet expectations. For this reason, it's best to take the sequence of photos as individual continuous images and then you use some kind of software tool to stitch them together in a proper way.
