AIX
Network Administration
Length: 5 Days
Audience: System
and Network Administrators.
Prerequisites:
Attendees of this course should have completed the AIX System
Administration course.
Overview: This course provides instruction on IBM AIX network
administration and security. Students will be introduced to networking
termonology and will learn how to administer the AIX TCP/IP network
through lectures and hands-on exercises. Topics include an overview
of network protocols, how to use the network commands, how to
install and configure network hardware, and how to configure standard
network services, including the network filesystem (NFS), Network
Information System (NIS), Dynamic Host Configuration Protocol
(DHCP), Domain Name Services (DNS), IP Version 6 (IPv6), and sendmail.
Attendes will also learn how to set up and manage network security
through the use of network scanner detection programs and other
tools.
Upon completion
of this course the attendee will be able to:
- Describe and state
the purpose of various network protocols.
- Configure network
hardware and software.
- Configure routing
and routing tables.
- Configure subnet
masks.
- Set up and manage
standard network services including telnet, ftp, NFS, NIS, DHCP,
DNS, and Sendmail.
- Examine and improve
the network security of AIX systems using network security tools
and programs.
- Troubleshoot common
network problems.
