Maen ArtimyComments Off on Building an OpenFlow Lab
Like many people, I have started learning about Software-Defined Networking and OpenFlow using Mininet, which is a great virtual environment to use. However, Mininet has some limitations, and I found myself looking for hardware alternatives. This article describes how to build an OpenFlow lab environment that can be used for… Read more »
Maen ArtimyComments Off on FlowManager – An SDN Application
The FlowManager is a RYU controller application that gives the user manual control over the flow tables in an OpenFlow network. The user can create, modify, or delete flows directly from the application. The user can also monitor the OpenFlow switches and view statistics. The FlowManager is ideal for learning… Read more »
Maen ArtimyComments Off on How to create Linux containers
Linux containers isolate applications from the host system that they run on and from other containers. Containers behave much like virtual machines, but unlike virtual machines, containers include only the software components they need to operate rather than an entire operating system. This improves performance and reduces the size of… Read more »

Are you looking for lightweight Syslog server to test your Fortinet®‘s firewall installation? or Is your firewall missing a local disk to save the logs? If your answer is ‘Yes’ to either question, then you may want to check out this Python script at GitHub. The script starts a syslog… Read more »
Maen ArtimyComments Off on SDN with Raspberry Pi and Zodiac FX
Experimenting with Software Defined Networks (SDN) on real hardware has become a lot easier since I discovered the Zodiac FX switch from Northbound Networks. This 4-port switch supports Openflow v1.0 and v1.3, and it supports many Openflow controllers. This post describes the process of connecting the Zodiac FX switch with… Read more »
This is my latest Android App and the first to be published in Google Play. The App provides you with basic information about any unicast IPv4 address you enter, including: the network id portion of the IP address given the mask length, the number of usable host IP addresses within the… Read more »
Maen ArtimyComments Off on Behind the Wall: The Internet Is The Computer
Back in the eighties, John Gage of Sun Microsystems coined the phrase, “The network is the computer.” Today, the services made possible by the Internet and our use of them as individuals and organizations affirm John’s statement perhaps in ways they were not even imaginable three decades ago. Technology trends… Read more »
Maen ArtimyComments Off on Behind the Wall: The Internet is Made of Light
(this is the third post of the series “behind the wall”. Here are the first and second) The Internet is made of light. That is because the Internet’s backbone is mostly made of optical fibre links that guide light pulses representing data streams. Optical fiber technology permits the transmission of… Read more »
