It would be nice if you could change these stored SSH passwords via the SecureCRT interface however I was unable to locate a way to do this. Instead you have to open the OSX Keychain and modify the SSH passwords via this interface instead. Below are instructions on modifying a stored SecureCRT SSH password on OSX.

Disable Trackbacks In Existing WordPress Blog, Stop WordPress Trackback SPAM

Trackbacks, also known as pingbacks, in WordPress are a great idea however they typically generate a lot of SPAM for little benefit. A trackback is generated within a post on your site by another bloggger linking to your WordPress article. Personally I disable the display of trackbacks in most WordPress sites however I still let the sites backend process trackbacks as it normally would. This means the person generating the trackback assumes that it functions properly and the WordPress site owner still receives notification via email of the trackback or pingback. Recently though my stance is changing to completely disable trackbacks on all posts and to go back and disable it in article that were previously published and disable trackbacks in those as well because the SPAM has been getting more intense over the past 6 months. Use the instructions below to disable trackbacks on your WordPress site.

IBM Java SDK Install Error: Failed dependencies: /usr/lib64/libstdc++.so.5 is needed by ibm-java-x86_64-sdk-6.0-9.1.x86_64

While setting up a websphere test server I ran into a minor dependency error during the beginning of installing the necessary packages for websphere. The IBM Java SDK RPM on CentOS 6 was complaining about a failed dependency of a libstdc++ library. The RPM I was attempting to install required libstdc++.so.5 and CentOS 6 has libstdc++.so.6 installed by default. All that is required is to install the libstdc++ compat RPM. The information below describes the error in more detail, how I located the package that installed the necessary file(s), and an example of installing the needed package.

OSX Burn Image Message: The Disc Drive Is Busy. Please Choose Another Drive.

When attempting to burn a DVD tonight I was getting a message from within the OSX Disk Utility stating that the Disc Drive was busy. At first I thought it must be a DVD that was not compatible with the DVD burner however I attempted to use three different types of DVD’s with the same message. Finally I realized that I had VMWare Fusion running and one of the VM’s I was using at the time was sharing the Disc Drive with the host OS or OSX. Below are more details about what the message from the OSX Disk Utility will look like and how to remove the disc drive from being shared with a VMWare image.
