#View the section below to learn about and perform an update on your fresh CentOS install (you may have to find spare time to perform this install if you are running short on lab time). '''Do <u>not</u> proceed to Investigation 3 without performing an update'''.
#The CentOS software is updated frequently to add features, fix bugs, and upgrade security. Perform a system update to get the latest versions of the packages installed: Start the Firefox web browser, turn off popup window blocking (select '''Edit>''', '''Preferences''', then select the '''Content ''' tab and uncheck the box to '''Block Popups'''), then return to your web-browser, load a page, and when prompted, login to SeneNET. #Open a terminal and type <b><code>su</code></b> to start a shell as root. Enter the command <b><code>yum update</code></b> This will download and install all of the packages that have been updated since the installation DVD image was created. If you complete this command at Seneca it should run quite fast as Seneca College hosts a CentOS Repository mirror (a copy of all of the current CentOS packages, on a local web server).
'''Answer the Investigation 3 observations / questions in your lab log book.'''
