Hands –on Project :
Project 6-1:
Step1: Logged in as root user on command line terminal tty2.
Step2: Command “ yum install system-config-kickstart”.
Step3: Downloading and installing packages by running the above command.

Step4: Switched to graphical terminal as other user.
Step5: Bash shell terminal.
Step6: Command “ system-config-kickstart” to open the Kickstart Configuration.
Step7: Configured and saved file as ks.cfg to /home directory of user.

Step8: Closed Kickstart Configuration.
Step9: Switched back to command line terminal.
Step10: Command “ less /home//ks.csf “

Step 11: Difference between the anaconda-ks.cfg file and the initial-setup-ks.csg file as as given below.

Step12: Logged out of shell.

Project 6-4:

Step1: Logged into shell.
Step2: *Not able to answer this as for some reason these log files are not created in my system.*Troubleshooting in progress.
Step3:
Step4: “ ls –F /proc”

Step5: Yes. The CPU configuration detected successfully.
Step6: List of modules currently present : “/proc/modules”

Step7: Yes. It does recognize the entire memory .

Step8:
Command “dmesg | less “ displays the kernel ring buffer messages which are recorded during the booting
sequence.
On the other hand /modules consists of the modules that are currently installed.

Step9:
Dmesg prints the contents of the ring buffer. This information is also sent in real time to syslogd or klogd, when they are running, and ends up in /var/log/messages; when dmesg is most useful is in capturing boot-time messages from before syslogd and/or klogd started, so that they will be properly logged.
Step10: Logged out of shell.
