As a Linux system administrator, one must master the services that servers will provide to clients on a Linux infrastructure. Servers provide services that clients need to use such as web services, IP address management, domain resolution services, email services, etc. These multitude of services run continuously in the background and respond as needed. The tasks of the administrator is to make sure these services are installed and configured properly so they are available when needed.

Systemd is becoming the standard version of software management on many current linux distributions. Watch the follow youtube video and look for some basic commands used in software management: https://www.youtube.com/watch?v=AtEqbYTLHfs (Links to an external site.).

In your discussion post:

Visit http://www.nongnu.org/lpi-manuals/manual/pdf/GNU-FDL-OO-LPI-202-0.3.pdf (Links to an external site.) and compile a list of three (3) different networking services that can be used on a Linux server. Try to select different services that your peers have not already posted.

Describe each of the three services and provide a screenshot or description of each. You may need to search the public web using a search engine like Google or Bing to find screenshots of systems with different services. Cite any sources you use in APA format; this includes sources for any screenshots that are not your own.

Visit the youtube website above and compile a list of three (3) different systemd commands that can be used on a Linux server and compare them with the older init versions of the commands (example: system start ssh.service vs service ssh start). Try to select different services that your peers have not already posted.

When responding to your peers' posts, describe your initial thoughts on the best advantage over the other system's services they posted. Note any major similarities or differences your notice between the different services.
