Lab Report
Question 1: What was the objective of the exercise?
In operating systems, there are many services running in the background. Same is the case with Linux based operating systems. Almost all of the programs or system services write to the log files about events. Minimum verbosity of events to be written in the log file can be changed in Linux based systems. Monitoring log files help in identification of the errors or security-related incident investigations. The objective of the exercise was to view the system log file in real time for log entries and to write any user messages in the log file using logger command.
Question 2: What was the outcome of the exercise?
The outcome of the exercise was two terminal windows running side by side allowing the real-time monitoring of log files. Main shell terminal was showing real-time entries as being written by the processes and user shell window opened by the tail command allows the user to write messages in the log file. In user shell window a log message "Hello" was typed and it was written to the log file in real time. Entering the wrong password in root shell generated a failed login attempt entry into the system log file observed by opening the log file into the terminal window.
Question 3: Explain your experience with the exercise?
The exercise was designed to equip students with practical experience of real-time log monitoring. No errors or technical issues were experienced while performing the lab. All the instructions in the exercise are self-explanatory. Appropriate execution of commands as described in the exercise generated desired output instantaneously. The task was completed successfully without encountering any potential issue. Overall the experience of performing the exercise in the lab was exciting.
