Linux Network Services

Course Description

The GL275 is an expansive course that covers a wide range of network services useful to every organization. Special attention is paid to the concepts needed to implement these services securely, and to the trouble-shooting skills which will be necessary for real-world administration of these network services. Like all Guru Labs courses, the course material is designed to provide extensive hands-on experience. Topics include: Security with SELinux and Netfilter, DNS concepts and implementation with Bind; LDAP concepts and implementation using OpenLDAP; Web services with Apache; FTP with vsftpd; caching, filtering proxies with Squid; SMB/CIFS (Windows networking) with Samba; and e-mail concepts and implementation with Postfix combined with either Dovecot or Cyrus.

Training Objectives

At the end of the training participants:

• Secure network services with SELinux, Linux Security Modules and Netfilter.
• Understand DNS concepts and implement DNS hierarchies and advanced DNS features with BIND.
• Install, configure and secure the Apache web server, including server-side scripting administration.
• Implement an FTP server as well as a caching and filtering proxy with Squid.
• Understand SQL fundamentals and administer a MariaDB database server.
• Understand LDAP concepts and implement a directory service with the 389 Directory Server and its clients.
• Configure SMB/CIFS (Windows) file and print sharing with Samba.
• Understand SMTP theory and implement e-mail services with Postfix together with mail retrieval services.
• Troubleshoot all the network services covered in real-world administration scenarios.
