Multi-web configuration for Railo 3.1 and BlazeDS

Seems like lots of people are having a problem with Railo configured for multiple websites on a single host, but also need to support AMF via BlazeDS.

The common symptom is when you restart railo services, sometimes you will get a big error instead of your web page that says something like:

MessageBroker failed to start: flex.messaging.config.ConfigurationException: MessageBroker already defined from MessageBrokerServlet with init parameter messageBrokerId = '__default__'

Here is what I found to work for me:

1. Read this post by Roland Ringgenberg at <a target="_new" href="">the railo google group</a> and follow the directions to install the java jar and edit the flex/services-config.xml file:

        <service-include file-path="remoting-config.xml" />
        <service-include file-path="proxy-config.xml" />
        <service-include file-path="messaging-config.xml" />      
<service id="railoBootstrap" class="">

2. For me, railo runs on port 8600 internally, and I have IIS configured to serve up content.  BlazeDS however doesn't get mapped through IIS, so you need to talk on the native port (again, for MY configuration, YMMV).  So to access it, i needed to open TCP port 8600 through the firewall.

3. Once i could talk to the server over port 8600, I changed my flex app that uses remoting to point to http://myserver:8600/flashservices/gateway/ and eveyrthing worked great!

One other interesting observation... When using Flash remoting with CF7/8/9, you can talk to your CFCs and invoke methods that are set to "public."  With BlazeDS, your methods need to be marked as "remote" to be accessible.  Minor syntax difference, but a huge impact on security.  make sure you secure your CFCs!

Installing python 3.4.x on OSX El Capitan

I love "brew" package manager, but sometimes being too progressive breaks things.  I have several python apps that I maintain that get deployed to AWS using Elastic Beanstalk.  AWS eb can deploy with python 2.7 or 3.4.  Any recent 'brew install python3" will get 3.5.1. #annoying

Making Macbook Air with 128GB SSD usable with Bootcamp

I recently got a new Macbook Air 11" (the 2012 version) and loaded it with goodies like 8GB ram and 2GHz Core i7.  What I DIDN'T upgrade was the internal SSD.  My config came with 128GB SSD and I refused to pay $300+ to upgrade it to 256GB.  Yeah I know, some call me cheap, but SSds cost $75-$150 for 240GB, so adding another 128GB for $300 seemed way too steep for me.  I figured "ok, I'm going to make 128G work!"

Here is the story of how that went...

Getting Started with OpenVAS on CentOS - an open source vulnerability scanner

The Open Vulnerability Assessment System (OpenVAS) is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution. (Taken from the OpenVAS website, which is at )

This blog entry will introduce OpenVAS version 3.1, walk through installation on CentOS and is intended as a "getting started" guide. I'll also do a guide for installing on Ubuntu later.
