Module Description: This module is focused on the study of advanced system and network administration topics for the Linux/Unix operating systems. Topics explored and implemented will include the setup and maintenance of many of the most popular network services including servers for DNS, LDAP, Web (HTTP, HTTPS), NAS and email (SMTP, POP3, IMAP). Special attention is paid to the concepts needed to implement these services securely and to the troubleshooting skills that will be necessary for real-world administration of these internet and network services.
