| GL-275 - Enterprise Linux Network Services |
| |
| |
| Students interested in developing skills as network
administrators find this course invaluable. Topics
explored and implemented in the class include the
setup and maintenance of many of the most popular
network services available for Linux and UNIX today,
including servers for DNS, LDAP, Web (HTTP, HTTPS),
FTP, SMB (Windows networking), and email (SMTP,
POP3, IMAP). 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 network services. |
| |
| Prerequisites |
| |
| Individuals wishing to take this class should
already have a solid grounding in UNIX concepts
and basic systems administration. Fundamentals such
as an understanding of the Linux filesystem, process
management, and the ability to manipulate and edit
files is considered a must and will not be covered
in class. A good understanding of network concepts,
and the TCP/IP protocol suite is also assumed. |
