The Federal Cloud First policy mandates that agencies take full advantage of cloud computing benefits to maximize capacity utilization, improve IT flexibility and responsiveness, and minimize cost. But how can you safely and reliably begin to deploy and manage your Red Hat instances at cloud scale? With IT automation, you can more easily deploy and manage your Red Hat instances in the Amazon Web Services (AWS) public cloud.
In this webinar, we’ll demonstrate how to:
- Automate the creation of Red Hat Enterprise Linux-based AWS instances
- Apply a security baseline to the instances
- Deploy and manage an application
Who Should Attend: Those in the public sector who are working to move to the cloud
Why Attend: Regardless of where you are in the cloud adoption process, leveraging IT automation can help smooth the transition to the cloud.
Presenter: Justin Nemmers, director public sector at Ansible
Date & Time: Thursday, July 23, at 2PM Eastern

In this post, I’m going to show you how to configure VLAN trunking with Mikrotik RouterOS, and along the way provide a brief introduction to this software and some of the functionality it offers. While it is Linux-based, RouterOS operates quite a bit differently than a lot of the other network operating systems with which I’ve worked, and so I hope that this post will help ease the learning curve a bit for others who decide to take the same path.
Background
First, let me provide a quick bit of background. I found myself in need of a switch that was both Layer 2/3 capable with both 10/100/1000Mbps ports as well as 10Gbps SFP+ ports. Of course, this was for my home lab, so budget is a concern. I cast out a quick call on Twitter, asking for some recommendations, and a few folks recommended I have a look at RouterBoard/Mikrotik; specifically, the CRS-24G-2S+IN (see here for more details). The specs looked good, the price was reasonable, and several folks expressed their satisfaction with the product, so I bought one.
Upon receiving it, I found myself trying to unravel RouterOS (their Linux-based operating system). Their wiki is fairly helpful, but Continue reading

A few weeks ago at AnsibleFest in NYC, we did something a little bit different: we assembled a panel of networking experts and had a very interesting discussion about some of the challenges and opportunities around networking automation. With representatives from Cisco, Cumulus, World Wide Technologies, and Network to Code, we dug into some of the reasons to automate your network, the technical and organizational challenges, and we reviewed some of the new Ansible modules being written for various networking components. Network automation is an exciting and early area for us, and we are looking forward to what the future holds.

I’ve been wrestling with an Ubuntu network configuration issue over the last couple of weeks (off and on between working on other projects), and today I finally found a fix for the problem. The issue was that Ubuntu wouldn’t pick up changes to network interfaces. The fix is so simple I’m almost embarrassed to talk about it (it seems like something that I should have known), but I’m posting it here in case others run into the same issue.
Here’s a bit more context: I was switching some of the network interfaces in my Ubuntu 14.04.2 servers from a “standard” network configuration to using VLAN interfaces (after all, it seemed like such a shame to not more fully utilize the 10GbE and 40GbE interfaces in these servers). Before the reconfiguration, the servers had a network interface configuration file (located in /etc/network/interfaces.d and sourced in /etc/network/interfaces) that looked something like this:
auto p55p1
iface p55p1 inet static
address 172.16.3.201
netmask 255.255.255.0This interface was connected to a port on a Cumulus Linux-powered Dell S6000-ON that was configured as an access port on a particular VLAN. Everything seemed to work just Continue reading
