That s it for this chapter Let s review what you learned
CERTIFICATION SUMMARY
In this chapter, you learned how to document and complete basic troubleshooting tasks on a Linux system We began this chapter by emphasizing how important it is for you to document everything you do with your systems Proper documentation will help you when you re troubleshooting problems with your systems It will also be an invaluable resource should you move on and someone else is hired to fill your position We then discussed the types of information that you should document First, you should extensively document new systems as soon as they are deployed You could consider documenting the following:
System manufacturer and model number Vendor purchased from and date purchased Warranty information Motherboard make and model number
Certi cation Summary
BIOS make and version number CPU make and model number RAM manufacturer, size, type, and installed amount Hard drive make, model, size, and geometry CD/DVD drive make and model number List of installed expansion boards Video board and monitor information Operating system distribution installed, including version number Date installed Disk partitions and mount points Additional kernel modules loaded Operating system parameters such as: Keyboard type and language Mouse type Time zone Packages installed Network board make and model Dynamic or static IP address If static, record: IP address Subnet mask Default gateway router address DNS server address Network services installed Network service configuration parameters
In addition, you should also consider documenting changes you make to your systems If you upgrade a component, install a new application, or enable a network service, you should document it You should document the following information:
Component changed Reason for change Date change was made
16: Documenting and Troubleshooting the System
New component information: Make Model Vendor Driver file
Maintenance activities should also be documented You should consider documenting information such as:
Backup Date the backup was run Type of backup (incremental, differential, or full) Media name Date interior was checked for excessive dust buildup Date baseline test was run and the results Updates Type of update Name of update installed Date update was installed
Next, you should document the procedures you follow in your day-to-day work Documenting procedures is not an exciting task to complete, but can be very beneficial It can help you identify problems and disconnects in your work It can also make it very easy for new hires to ramp up The actual procedures you document will vary from organization to organization Here are some suggested procedures to include in your documentation:
Procurement Installation Configuration Security Management
At this point, we changed the focus of the chapter from documentation to troubleshooting We pointed out that troubleshooting is part skill and part art form To be a good troubleshooter, you need the following:
