LPI 202. Selected network services and network security

Categories: Linux administration, Linux (LPI), Networking

A practical overview of the most important network services for an administrator: from Apache, proxy servers and Samba, through NFS, DHCP servers and LDAP, to mail servers, security and troubleshooting and monitoring.
A preparatory training for the LPI 202 exam, which is organized by Linux Professional Institute. Passing this exam and the LPI 201 exam allows one to acquire the LPIC-2 certificate – Advanced Level Linux Certification.

We offer this training, combined with the LPI 201 training, as an alternate path for our classical LPIC-2 training path (the Linux Administrator course and a supplementary course), for persons interested only in the LPIC-2 certification who already have some familiarity with Linux administration.

For persons interested in a more in-depth look at the topics covered during this training, we recommend the Advanced Linux Administrator course, which provides a thorough coverage of several advanced technologies.
