Collection of useful, relevant or just fun places on the Internets for 8th May 2014 and a bit commentary about what I’ve found interesting about them:
Whitebox Switching: Would You? Should You? — The Peering Introvert – Ethan Banks takes a good hard look at Whitebox Switches after a session at ONUG inspired some more Whitebox switching is the idea that the silicon & box can be bought as one thing, and the network OS and applications as other things. This idea is counter to the traditional norm of network switch acquisition. Today, most customers purchase switching as a vertically integrated stack. The same vendor supplies the network hardware as well as the network operating system & applications. The network operating system is not able to be changed by the networking consumer.I expect that Whitebox switches will replace some percentage of your overall Ethernet network. You can certainly have some in your network to reduce overall cost and to coerce vendors into providing more reasonable pricing when you have at least some in your data centre.
Glui – Still the best app for snapping images on Mac OS X, annotating and uploading to Dropbox. Snapping is more & more important as we move into cloud & sdn networkings.
The simplest way to capture, annotate and share screenshots.
IPv4 Countdown – Phase 4 – ARIN starts Phase 4 of IPv4 end game and is the last major registrar (APNIC & RIPE are already there). In the meantime, IPv6 support and reliability in network devices is still ….., well, …… inconsistent.
What I Learned After Quitting Email For A Week – No one noticed he quit email for a week.
Perhaps the biggest lesson, though, came at the expense of my ego. During my week away from email, nobody seemed concerned by my absence. There were no frantic emails asking where I was or worrying that I hadn’t promptly responded to threads. Those that really needed me got in touch some other way. As it turns out, the service that I spend so much time and effort worrying about, checking, and manicuring can and will continue to exist without me. I quit email for a week and nobody really noticed or cared except for me.
Inktank Acquisition – Jeff Darcy on the CEPH acquisition by Redhat. Jeff is a long storage developer and open source advocate. If he says it’s good, then it’s good.
One of the nice things about joining forces is that we each gain even more freedom than before to borrow each other’s ideas. Yes, they were both open source, so we could always do some of that, but it’s not like we could have used one project’s management console on top of the other’s data path. GlusterFS using RADOS would have been unthinkable, as would Ceph using GFAPI. Now, all things are possible. In each area, we have the chance to take two sets of ideas and either converge on the better one or merge the two to come up with something even better than either was before. I don’t know what the outcomes will be, or even what all of the pieces are that we’ll be looking at, but I do know that there are some very smart people joining the team I’m on. Whenever that happens, all sorts of unpredictable good things tend to happen.
Jesper Dangaard Brouer – DDoS protection using Netfilter/iptables – YouTube – Youtube video of Jesper Dangaard Brouer – DDoS protection Using Netfilter/iptables
Can Netfilter/iptables really be used for DDoS attack protection? I though it was too slow for that.
In this talk I will present the recent developement, for mitigating DDoS attacks using Netfilter/iptables, the Linux kernels firewall facility. The talk will cover the recent SYNPROXY modul and other less know techniques, and the needed kernel parameter tuning.
