If you have created a custom RightScript in the RightScale interface that uses git to clone a repository and you are running that RightScript on boot following the RightScale git_repo recipe then you likely are having issues. The problem appears to stem from the fact that the environment variables are not completely cleaned up as expected including $GIT_SSH and possibly others. I have a work around noted below along with a line you can enter in your RightScript to clear the $GIT_SSH ENV variable as well.

The below code snippet was used to add SSH users to RackSpace cloud CentOS Linux nodes being used as application servers and managed via RightScale. The SSH users were required during a testing phase so they could look through logs and make modifications to specific configuration files, etc. There are three things that have to happen to create the SSH user, allow them to login, and provide them the necessary rights on the server to accomplish their tasks which include adding the user, modifying the sshd config to allow password logins, and update the sudoers file to enable sudo access for wheel group users.

Recently I was working on a project that was using RightScale to manage RackSpace cloud nodes. One of the requirements of the project was to have application nodes scale automatically thus they were required to automatically install software, configure settings, and start services automatically on the RackSpace CentOS nodes being used. Most everything was fairly straight forward however some of the services we were using would not start properly and initially because of the lack of logging from the services we were unable to figure out what the problem was. Below I describe the problem in more detail along with the solution which involved updating a configuration file on the CentOS Linux servers and then restarting the services.

While trying to disable Skype from starting up automatically because of Skype 5.X’s horrible user interface I ran across some settings that I was previously not aware of on Mac OSX Lion. Specifically I found the location where all of the applications that automatically start at login are listed.  I was really happy to find this setting as there were a bunch of applications that I had previously uninstalled and there were still traces of those applications in places such as the Login Items list that had not been removed with the applications.

I had a Acer aspire one in the shop today and it had a variety of critical Windows issues. While doing some tests one of the things I did was rebuild the windows boot loader using the /FIXBOOT & /FIXMBR commands from a recovery disk. What I did not realize is it seems Acer has a custom boot loader which allows for the keys Alt & F10 to be pressed on boot in order to reinstall from the recovery partition so when I reinstalled the boot loader I overwrote the Acer one. This prevented the Alt – F10 combination from being used to access the recovery partition. Now, normally if you can boot into Windows there is a icon in the start menu to execute the recovery program but in my case Windows was so messed up due to a bad chkdsk I was not able to do that.
