VMworld 2017 Prayer Time
At VMworld 2017 in Las Vegas, I’m organizing—as I have in previous years—a gathering of Christians for a brief time of prayer while at the conference. If you’re interested in joining us, here are the details.
What: A brief time of prayer
Where: Mandalay Bay Convention Center, level 1 (same level as the food court), at the bottom of the escalators heading upstairs (over near the business center)
When: Monday 8/28 through Thursday 8/31 at 7:45am (this should give everyone enough time to grab breakfast before the keynotes start at 9am)
Who: All courteous attendees are welcome, but please note that this will be a distinctly Christian-focused and Christ-centric activity (I encourage believers of other faiths/religions to organize equivalent activities)
Why: To spend a few minutes in prayer over the day, the conference, the attendees, and each other
You don’t need to RSVP or anything like that, although you’re welcome to if you’d like (just hit me up on Twitter). There’s also no need to bring anything other than an open heart, your faith, and your willingness to display that faith in front of others. This is quite casual—we’ll gather together, share a few prayer requests and needs, and Continue reading

Slowloris all the things
At DEFCON, some researchers are going to announce a Slowloris-type exploit for SMB -- SMBloris. I thought I'd write up some comments.The original Slowloris from several years creates a ton of connections to a web server, but only sends partial headers. The server allocates a large amount of memory to handle the requests, expecting to free that memory soon when the requests are completed. But the requests are never completed, so the memory remains tied up indefinitely. Moreover, this also consumes a lot of CPU resources -- every time Slowloris dribbles a few more bytes on the TCP connection is forces the CPU to walk through a lot of data structures to handle those bytes.
The thing about Slowloris is that it's not specific to HTTP. It's a principle that affects pretty much every service that listens on the Internet. For example, on Linux servers running NFS, you can exploit the RPC fragmentation feature in order to force the server to allocate all the memory in a box waiting for fragments that never arrive.
SMBloris does the same thing for SMB. It's an easy attack to carry out in general, the only question is how much resources are required Continue reading

Moving to a private cloud tips and considerations
There are a lot of reasons you may be thinking about moving to a private cloud environment. Perhaps you need more security, or maybe you feel the risks of public cloud have outweighed the benefits. But you’re still not certain that this version of web-scale networking is right for your company, and you’re wondering what’s involved in moving from a public cloud to a private one. Not surprisingly, there are several factors to consider when making the move from public to private clouds. Public clouds have their place, but there are many good reasons to switch. In this post we’ll covers some private cloud tips and considerations.
For an even deeper look at reasons you may want to switch to a private cloud, check out our education page, Private Cloud vs. Public Cloud.
Level set: Defining public, private and hybrid clouds
Private clouds take several different forms: semi-private cloud, virtual private cloud (hybrid), and fully private cloud. Each one has their advantages and disadvantages.
Semi-private clouds are similar to public clouds where the cloud is being hosted by a provider, but the access to the cloud is through private channels and not over the Internet. This reduces the problem of lag Continue reading

Contrarian Reading on Net Neutrality
‘net neturality has been much in the news recently; a while back I did a piece for Tech Target on some of the complexities here, and I ran across three other articles that provide a contrarian view—not what you are likely to hear from the major edge providers. Since I am always trying to understand both sides of an issue, I am always looking for solid, well written views on both sides. It is hard to dig behind the hype in our 140 character world, but it is also important.
Hence this post, with pointers to my older post and three other articles of interest. Warning: some of these are more trenchant and contrarian than others.
The primary foundation of net neutrality explained is this: Providers should not be able to give services they offer any advantage over a competing service running over their network. The perfect example might seem to be voice services. Suppose you purchase access to the internet from a company that not only sells internet access, but also voice services. Now, suppose the provider decides to sell its voice service as superior in quality to any other available voice service — and guarantee its service is Continue reading
