Lab 1.2: Update a Windows-Based System
1.8.1. Lab 1.1: Update a Linux System
It is important to keep your system current and up-to-date. As soon as a weakness in an operating system becomes known, the number of people trying to exploit that weakness grows at an almost exponential rate. In this exercise, you'll apply patches and updates to an SuSE Linux Enterprise Server (SLES).
To apply patches and updates through YaST, the primary administration tool in SLES, follow these steps:
Log in as root and start YaST.
Choose Software and then select Online Update.
Click Next. YaST retrieves information about new updates. If prompted for a username and password, enter these values, and then choose to install any updates that are found.
You can also choose to install patches from a CD by selecting Software and Patch CD Update. To specify settings on the server, choose Software and then System Update. Choose Change and then Update Options.
Finally, the YOU (YaST Online Update) server can be configured by choosing Software and then YOU Server Configuration.
1.8.2. Lab 1.2: Update a Windows-Based System
Whether you are running Windows Server 2003 or 2008, you'll use these steps to look for updates to your system and to begin installing them:
Log in as administrator and start Microsoft Internet Explorer.
Click Express. The system will be checked, and you can choose to install any updates that are found.
