As I feel this may be a regular section of the blog due to my lack of availability. Please suggest a better name for this “series”. I would certainly appreciate it, as would my readers who have heard enough of my bad humor…
SSL as we know it has been compromised!
The other Tony, as in Tony Bourke has brought to my attention the recently BEAST exploit that compromises TLS1.0 aka, SSL as you know it. This has been fixed in TLS 1.1 and 1.2, but as it seems, there is very little support out there for anything but TLS 1.0 thanks to the OpenSSL project.
TLS 1.2 and NLB
This is a follow up in a way to the article above, Tony talks about solving the TLS issue using NLBs.
IT Panic Mode
Tom bring up some very good points discussing how engineers deal with stress during outages. And he throws out a great Ghostbusters quote!
Nexus BFD
Interesting article discussing some oddities in the way the Nexus handles BFD processing.
The Reason Enterprises aren’t deploying IPv6
Ethan brings up some great points here discussing why Enterprise enviorments haven’t deployed IPv6, or in many cases, haven’t even considered it.
IPexpert IOU Topology
@jdsilva has built a great IOU Netmap for use with IPexpert’s CCIE R&S labs.
The Last Cable Tool…
Tom has found an interesting tool put out by Gerber. I’d like to see one of these in the store so I could get a feel for it before throwing down some hardcore cash…
MPLS is not Tunneling!
Yet another great post by Ivan, discussing the differences between MPLS virtual circuits and a true tunnel.
Is RIM using Cisco Nexus?
This weeks RIM failure was apparently caused by a core switch failure within their infrastructure. They stated that, “Although the system is designed to failover to a back-up switch, the failover did not function as previously tested.” — This makes me wonder if they’ve experienced some of the same fail over issues as we have with the Nexus line. As these have been fixed in later revisions of code, I would certainly hope this wasn’t the case.
Network engineer turned management currently servicing the enterprise data center market. I started working on networks in the ’90s and still feel like that was just a few years ago. Jack of all trades, master of none; I love to learn about everything. Feel free to ask me about photography, woodworking, nhra, watches, or even networking! — For feedback, please leave a comment on the article in question, and I’ll respond as soon as I can.
