Course details
Prepare for certification by reviewing the essentials involved in Linux engineering. First, review DNS management including installation, creating lookup zones, supporting mail servers, and securing BIND with DNSSEC. Next, explore web services including Apache web server setup, configuring web and virtual servers, redirecting URLs, enabling SSL encryption, installing a Squid proxy server, and implementing NGINX. Then dive into the file sharing chapter which covers Samba client and shared folder configuration, Active Directly integration, configuring an NFS client, and controlling access. Then study network client management by reviewing DHCP server management, authentication server setup with OpenLDAP, and TLS configuration. Email service tasks shown include building an SMTP server with Postfix, supporting IMAP and POP3 with Dovecot, and using Sieve for filtering emails. Lastly, brush up on system security including router building with iptables, port configuration, firewalls, building an FTP service with vsftpd and Pure-FTPd, blocking brute force attacks, checking for open ports, and building a VPN service with OpenVPN.
