Kubernetes install gotcha on CentOS-7.x

Posted on September 11, 2019September 11, 2019 by Percy Kwong

Hey for all of you hand-rolling a Kubernetes / Docker cluster, I thought I’d mention a bug with Centos 7.x that is still yet to be fixed.  The error is: /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory. The fix is simple.  Just execute the following command (as root). $ modprobe -v br_netfilter Problem solved.  If you…

Does SSL matter? It does and it’s not just web encryption.

Posted on September 4, 2019September 4, 2019 by Percy Kwong

Over the last decade, there’s been an ever growing emphasis on security.  SSL is taking a seat “Front-Row center” on this period of enlightenment.  Interestingly enough, it’s not just about encrypting your traffic on the web.  The purpose of this is far deeper.  This article will delve into the “why” SSL’s importance has grown and…

Apache can’t serve the .well-known directory

Posted on August 27, 2019August 27, 2019 by Percy Kwong

In an effort to set up SSL validation for this domain, I decided to use the Hash Validation technique.  Needless to say, it’s never as straight-forwards as you want.  Apache doesn’t like to serve the .well-known directory as it gives a “permission denied” error.

Encryption type Matters with Deep Packet Inspection – solved

Posted on July 4, 2012 by Percy Kwong

I was helping a client yesterday set up a VPN tunnel only to have it constantly disconnected.  The client was located outside of the country.  For the sake of avoiding throttling and saving on CPU, we were using the Blowfish cipher and it kept on getting disconnected. I found this rather strange as I’ve never…

Database Backed Web Applications Advice

Posted on July 2, 2012 by Percy Kwong

Here’s the scenario.  You’ve got a dedicated server running windows in a server farm (generic dedicated server provider).  You have mysql + asp or php app running all on the same server.  Raid 1 mirroring and 2 GB of ram. You have to have windows, because your application supports it.  Sound Familiar?  It’s a problem…

International Text solutions – A solution

Posted on July 1, 2012 by Percy Kwong

The thing that kills me more than anything is the International Texting thing today.  You get charged upwards of .50 to text international. So here’s the solution for all of you people out there.  Skype. Just install skype and register your cell phone number to it.  (requires validation, but worth it).  When you need to…

A Perfect Example of Disaster Recovery in the Cloud

Posted on June 30, 2012 by Percy Kwong

Netflix went down yesterday due to power problems at Amazon’s Virginia Datacenter.  This of course caused an outage for some of Amazon’s EC2 customers. (Like Netflix).   This is a perfect example of why Redundancy in the cloud is important. All of my customers (some of them at EC2 Virginia) stayed up and available.  How?  Redundancy….

What happened to “Human” in Humanity?

Posted on June 24, 2012 by Percy Kwong

I really do need to ask this question.  I appreciate my followers and yes, they’re a loyal bunch.  I do need to EVERYBODY one question and everyone on the Internet. We all go about our lives.  We see the homeless person at the exit ramp, on the sidewalk, etc.  Granted a lot of them are…
