The rsyslogd daemon can maintain logfiles on Linux distributions. Discuss how you would use the rsyslogd daemon to maintain a large number of log files.
Rsyslogd Daemon is used to log the system message on linux distribution. The Rsyslogd Daemon reads a socket and sends the socket message to a destination.
Since, maintaining individual log file is a cumbersome process hence centralize log management like Rsyslogd Daemon is used to store and manage all the logs at one place.
Rsyslog is the most popular daemon for centralizing log data because it’s installed by default in most common distributions of Linux.
Logs could be sent to a log server with ample storage to keep a copy for search, backup, and analysis.
One can centralize all the files in a directory or matching a wildcard pattern. The nxlog and syslog-ng daemons support both directories and wildcards (*).
Below mentioned are some of the best practices for application logging, especially in case of large number of log files.
Set a Standard Location for Log Files
Use A Standard Filename: Use a standard filename for the latest logs from your application. This makes it easy because you can monitor and tail a single file.
Append the Log File: Is the log file going to be overwritten after each application restart? If so, we recommend turning that off. After each restart the app should append to the log file. That way, you can always go back to the last log line before the restart.
Appending vs. Rotation of Log File: Log Management is much more easier in Rotation than Appending. Searching the log of a aprticular day/event is easier in a smaller file of that particular day or week, in compariosn with the larger appended file. Also, older logs could be deleted while rotation is used.
Retention of Log File: Based on business requirement, it needs to be decided that, how long one need to kaap log file stored.
Separate Disk Location for Log Files: If Log files are much in number, a separate disk could be used to store all the log files. It will help to manage and search the log details.

Linux provides distributions that are geared for Linux servers. Research two Server distributions and discuss the following: How are Linux server distributions different? What additional information is required during the installation process compared to other Linux distributions? Describe the most common problems that occur during a Linux installation and discuss the steps that should be taken if a fatal signal 11 (also known as a segmentation fault) error occurs.
Discuss whether you would prefer to use a Linux or Windows boot loader on your home OS and why.
Discuss how a manager of a retail store can use both the binomial and Poisson distributions to make business decisions. Explain how the distributions differ. Provide examples of the type of data that could be used in calculating the probabilities.

Kali Linux “Live” provides a “forensic mode”, a feature first introduced in BackTrack Linux. You can search the Kali URLs, and discuss how to operate/use the Kali, how to take advantage of bug filing systems to troubleshoot problems. Finally, discuss how to use Autopsy Forensic browser.
Starting from the Linux default permission for file and directories, what umask would you use to ensure that for all new files, the owner would have read and execute; members of the group would have read, write and execute; and others would have execute?
Discuss how you would configure your Linux distribution to perform name resolution using DNS. Compare and contrast the following programs which are helpful in debugging TCP/IP networks: nslookup, host, dig, whois. Ensure you provide terminal output in your discussion.
Take the time to list the different flavors of Linux. List all of the different distributions. HINT: There are seven main categories. Then list at least three different types of Open UNIX OSs. For each category, list at least three examples. Research the type of support that each of these flavors get, along with the software support. I also want to know if this particular flavor of Linux has a definitive purpose, for example, is it used for desktop PCs...
using node js as a shell and on a linux system. Will UPVOTE!! How can you find the inode number of a file in node? How can you change the inode number of a file in node?
Linux Question: I just need the command for the below: How many files are below “/etc/”? In other words, I want the number of files that are in this directory andany directories below it. You will need to use the “find” command to get this number and it is between 500 and 2500.
