In this 14-video course, learners will explore how Linux-based systems operate, communicate, and manage the underlying information they contain. Begin by examining management and monitoring tools available in Unix and Linux environments. Then learn to work with user accounts and domain names, and learn how to monitor user and system activity. You will learn how to securely connect to remote servers by using secure shell (SSH), and how to work with user accounts. This course examines elements of both an Internet Protocol routing table and a network interface, and demonstrates how to perform Domain Name System lookups. Learners will examine log files for monitoring critical events on a Linux system and use the PS command to retrieve process information. You will learn how to retrieve disk usage, partition information, and directory contents of a Linux system, and how to monitor both user and system activity on a Linux system. Finally, this course demonstrates how to configure time and date services and explore system configurations in the /etc folder of a Unix system.
