Last week I published slide decks for Network Function Virtualization, BGP-Based SDN Solutions and SDN Use Cases webinars – they’re available to subscribers and attendees registered for individual webinars.
Content from all three webinars is part of my SDN workshop – if you’d like to hear a live explanation, register for one of them.
I made a conscious decision to move away from full-time information security work. I retain an interest, and try to keep up with developments, but I don’t want to be “the security guy.” There are several reasons for it, but a large part is due to the hype, the bullshit, and general inability for the security industry to act like grown-ups.
The most frustrating part was the inability to properly classify risk. Robert Graham put this eloquently here:
Infosec isn’t a real profession. Among the things missing is proper “risk analysis”. Instead of quantifying risk, we treat it as an absolute. Risk is binary, either there is risk or there isn’t. We respond to risk emotionally rather than rationally, claiming all risk needs to be removed. This is why nobody listens to us. Business leaders quantify and prioritize risk, but we don’t, so our useless advice is ignored.
Security folk often forget that they are just another risk. Yes, it’s a risk shipping the product with that bug. But not shipping at all might be a larger risk to the business. Even complete data breach may or may not be catastrophic to the business – RSA is still Continue reading

Here is Part 1 of the CCR1072-1G-8S+ review in case you missed it!
CCR1072-1G-8S+ Ultimate BGP Performance test
After many days of testing, Part 2 is finally here! Welcome to the stubarea51.net BGP gauntlet. We subjected the CCR1072 to different types of network torture stress testing. Continuing on from our initial review, we chose BGP as the first way to test the limits and capacity of the CCR1072-1G-8S+.
Here is an overview of our lab environment to test the new CCR
All RouterOS devices were loaded with the latest stable code (6.30.1 at the time of testing)
Network Design of the StubArea51 LAB setup for BGP testing
For this series of testing, we took our two ESXi 6.0 hosts and built a number of VMs using RouterOS and Ubuntu to supply the 1.21 Gigawatts 3.6 Million routes we would need to beat up on the CCR1072 for a few days. If you’re not familiar with the RIPE Routing Information Service Continue reading
I have been investigating a problem where an application would install on RHEL/CentOS, but not on Ubuntu. I tracked it down to a problem with shell scripts that assumed that /bin/sh was bash. Ubuntu uses dash by default, so some ‘bashisms‘ don’t work. This will be old news to Ubuntu types that migrated to dash a while back, but I normally use CentOS/RHEL systems, and/or well-behaved cross-platform scripts. Luckily ‘checkbashisms‘ can help with figuring out what changes are needed.
I don’t want to go into the history of Unix shells, but there are probably more shell variants than there are *nix variants. Some are very different, and completely incompatible. But others are only different in subtle ways, and most things works without modification. If your script explicitly calls the required shell with “#!/bin/zsh” or “#!/bin/csh”, all will be fine. The problem comes when your script starts with “#!/bin/sh”. That will call the system shell, which can vary across different systems. If you’re using that, your script should be portable, and only implement a subset of possible functionality. People get in the habit of using “/bin/sh”, but using shell-specific features. That’s when things get ugly when you run Continue reading
The CloudFlare team is heading to HostingCon 2015 in San Diego next week. We are excited to meet colleagues from the industry, reconnect with partners, and make new friends.
This year’s conference marks a milestone of sorts. It’s our fifth time at HostingCon and we’ve come full circle - our first HostingCon took place in San Diego. Here are some fun facts on what we’ve accomplished since our first HostingCon in 2011:
Today, CloudFlare is trusted by over 5,000 partners who offer performance and security to millions of customers accelerating and protecting websites, APIs, and mobile apps. We work hard to deliver real savings for our partners. For example, over the past month we saved our partners more than 25 petabytes in aggregate bandwidth (roughly equivalent to 350 hours of HDTV video); stopped 65 billion+ malicious attacks that would Continue reading
Network Operators Groups (NOGs) are integral to the running of the Internet. They're also great resource for network engineers. Providers tend to build large, complex networks, and they are generally very open about sharing how they're doing it -- from tools to techniques to equipment to processes.
