Course details
Red Hat Enterprise Linux is one of the top enterprise Linux distributions. In this complete guide, Grant McWilliams—consultant, speaker, writer, professor, and developer—introduces you to IPv6 networking, link aggregation and static routing. Grant covers advanced system authentication using LDAP and secures it with Kerberos. Using Apache, he creates secure virtual hosts using TLS security and access control. To provide name service resolution, Grant creates a DNS server using bind and troubleshoots client issues. He dives into network file sharing using both NFS and Samba, as well as securing the latter with Kerberos. Grant also uses SSH to provide security for both the host and users. Plus, he synchronizes the system time with NTP and discusses how to manage MariaDB, including backing up and restoring databases.
