This course covers the steps you must perform to configure and run TCP/IP on an IBM i system.
The course begins with a review of the hardware and software required to support TCP/IP on an IBM i system. It then introduces a sample intranet that is used as a case study example throughout the remainder of the course.
Next, the course shows you how to configure a TCP/IP interface, start TCP/IP, and test the network connection. For complex networks, you will see how to specify routing information for hosts not within the local subnetwork.
TCP/IP application servers are discussed next. You will see how to start and end individual servers and control whether a server is started automatically when TCP/IP is started.
The course then describes the ways in which the domain names that are used on your system can be translated into their corresponding IP addresses. These methods include defining a local host table, using a remote domain name server, and using the IBM i system as a domain name server.
Depending on its release level, your IBM i system may also support TCP/IP over various types of point-to-point connections. You will see how to configure connections that use the Point to Point Protocol (PPP).
Finally, the course discusses IBM i security considerations, listing steps that you can take to enhance the security of an IBM i system in a TCP/IP environment.
Approximate Study Time: 2 hours
After completing this course, you should be able to:
- Determine whether the TCP/IP software has been installed on an IBM i system
- Identify the IBM i authority needed by a user to configure TCP/IP
- Interpret an intranet addressing diagram
- Configure a TCP/IP interface for an IBM i system
- Specify routing information for hosts not within the local subnetwork
- Display the status of the TCP/IP network
- Start and end TCP/IP
- Start and end TCP/IP application servers
- Control whether a TCP/IP application server is started automatically when TCP/IP is started
- Specify the full local domain name for an IBM i system
- Update IBM i's local host table to identify other hosts in the network
- Identify a remote system to be used as a domain name server
- Configure a TCP/IP point-to-point connection
- Start or end a TCP/IP point-to-point connection
- Identify steps you can take to enhance the security of an IBM i system in a TCP/IP environment
- Restrict access to the TCP/IP ports
- Prevent a TCP/IP user from signing on as the security officer
Configuring Application Servers
Defining a Point to Point Connection
This course is intended for IBM i professionals who will install and maintain TCP/IP on an IBM i system.
This course assumes that you are familiar with the concepts and basic operations of IBM i systems. This prerequisite can be satisfied by successfully completing the Introduction to the IBM i Environment series. A knowledge of data communications fundamentals is also required.
The course also assumes you have a basic understanding of TCP/IP concepts and facilities. This prerequisite can be satisfied by successfully completing the previous courses of this series:
