Linux has networking and system security as two of its fundamental design goals. Linux functions as the e-mail server for a large number of businesses and organizations. Those wishing to provide POP3 and IMAP mail access often turn to a system such as Courier or Dovecot to provide these services. This course demonstrates how to configure these systems. In addition, because of its strong-networked and secure framework, Linux can be configured as an excellent network router for small to medium applications. This course demonstrates how to configure Linux as a router and also provides the learner with the groundwork for securing and testing the security of a Linux installation. This course is for people taking Advanced Level Linux Professional (LPIC-2) Exam 201.
