I built a twitter bot

For some time I have been trying to learn Python, a programming language that is easy to use and the preferred one for many network engineers taking the first steps on automation. I read some books, watch some youtube videos and create some dumb scripts. But what really helps is creating a project, however small it is and doing it from start to finish. So, I decided to build a twitter bot.

Angolan CCIEs: How many?

As I was writing another post I realized it’s been a while since a 2 year old could count he number of CCIEs in my country.

Jeriel Atienza and André Malungo were for a long time the only Angolan CCIEs, but today the numbers are quite different.

I do not plan to make this the Angolan version of the CCIE Hall of Fame page but you can  find below the current list of Angolan CCIEs that I could find: Continue reading

After 5 years contributing the best I could to get the company of it’s feet, the time was coming for the progression many wished in their professional careers. I was invited to be the head of IT.

Demystifying the Cloud

The interest in cloud computing has been growing inside me for quite a while. Its advantages, how it works and the technologies involved.

In the middle of all this I found a very interesting document that I saved from being eaten by my son. I was lucky to arrive on time.

Demystifying the Cloud helps us understand the history and the path taken to where we are today, virtualization, the essential characteristics of the cloud and in the end quickly describes the top 3 cloud computing providers. While it was written in 2012 and I already knew parts of it, it was still relevant to remind me of the concepts and strengthen my little knowledge.

The author of the document is Janakiram MSV and his site www.janakiram.com its one of those you should bookmark if cloud computing and technologies are your thing.

Packet Capture Capabilities of Cisco Routers and Switches (Mind Map)

From very early in my networking career I have been fascinated by protocol details, packet captures and the features of my top 3 application troubleshooting tool: Wireshark.

Getting the captures on the endpoints (clients/servers) is relatively easy but things can get difficult when you want to capture traffic somewhere in between and is hard to do port mirroring (SPAN) on some remote switch.

Packet Capture Capabilities of Cisco Routers and Switches is an old video (4 years is old right?) posted on the Cisco Support Forums that highlights different methods to get on box packet captures in Wireshark .pcap format or in text output.

The video is an hour long but if you’re in a rush I made it easy for you by summarizing the video in an “easy to read” mind map. grouped by IOS, NX-OS and IOS XR. Continue reading
