we have four servers which are supposed to be exactly same, but over the time some differences have been made on them, for example some packages have been installed on one of them and not others, or the RAM and CPU is different, and also some of them are on vmWare ESX, so we'll need to get RVtools information as well. I need someone who is expert in Linux Redhat and can do scripting, especially on Python. The job is about writing a script to get the information of a Linux server and generate an XML file from it, and by information I mean any details about the server, from CPU, RAM to the hostname, DNS, running services, users, raid controller, storage and other characteristics that is specific for that server, I also have a sample that I found on the internet that is attached. Other than this file, I have another file that you can using these two files and gathering the good points of both and also add yours and make a good script, the output should be in XML. This is job is very urgent and the bonus would be very good. The initial draft version should be ready less than 24 hours, so please let me know if you are available in 24 hours, when we present the initial draft to my client, we will then continue to complete it during next 5-6 days. We dont have access to the servers for security reasons, so you should have Linux Redhat in your lab.
