In this video, Tony Fortunato shows how TFTP can be problematic when transferring files between network devices.
The DevOps tool isn't easy to learn, but the payoff is increased efficiency in your server room. Shawn Powers explains.
The featured webinar in May 2016 is the Overlay Virtual Networking webinar and in the featured videos (the ones marked with a star) you'll find introduction to overlay virtual networking and deep dive into flooding and MAC address learning in layer-2 overlay virtual networks.

Firepower is the name of Cisco's (formerly Sourcefire's) so-called Next-Gen IPS. The IPS comes in many form-factors, including beefy physical appliances, integrated into the ASA firewall, and as a discrete virtual machine.
Since the virtual machine (likely) does not sit in-line of the traffic that needs to be monitored, traffic needs to be fed into the VM via some method such as a SPAN port or a tap of some sort.
Very early on in the company’s history we decided that everything that CloudFlare does on behalf of its customer-base should be controllable via an API. In fact, when you login to the CloudFlare control panel, you’re really just making API calls to our backend services. Over time that API has matured and improved. We are now on v4 of that API.
The current CloudFlare API is documented here and it’s used by both the CloudFlare control panel and directly by umpteen customers every minute of every day. The new API is designed with a clean naming structure and consistent data representation for data. It’s also extensible.
This blog entry introduces python-cloudflare, a Python wrapper providing full access to the CloudFlare v4 API.
Let’s get right into the thick-of-it with the simplest coding example available to show python-cloudflare in action. This example lists all your domains (zones) and also checks some basic features for each zone.
#!/usr/bin/env python
import CloudFlare
def main():
cf = CloudFlare.CloudFlare()
zones = cf.zones.get(params={'per_page':50})
for zone in zones:
zone_name = zone['name']
zone_id = zone['id']
settings_ipv6 = cf.zones.settings.ipv6.get(zone_id)
ipv6_on = settings_ipv6['value']

Today we’re announcing the sunsetting of CloudFlare’s first client API, API v1. Starting November 9th, 2016 at noon Pacific Time (20:00 UTC), CloudFlare will no longer be supporting API v1.
While it is bittersweet to let our first API from CloudFlare’s early days go, we are so excited to show you all of the great things about our latest API: API v4. We’re confident that once you get started using it, you’ll see how easy API v4 makes managing your CloudFlare settings.
(For those of you who are curious where CloudFlare’s API v2 and v3 went, they ran away with IPv5 and PHP 6.)
If you are using API v1 and need to migrate to API v4, we’ve written extensive migration docs here for you to follow. They contain every API call from v1 and their equivalent in v4 side by side.
After CloudFlare discontinues support for API v1 in November 2016, any calls to API v1 will return the HTTP status code 410 Gone with the message: “This API has been deprecated in favor of API v4, available at https://api.cloudflare.com.”
CloudFlare uses Continue reading
