POWERUp 2019

The IBM i OS network communications has changed a lot since the AS/400 primarily communicated to workstations and printers using Twinax and to other computer systems using specialized communications lines. In some ways things are more complex because our IBM i OS systems communicate to a lot of other devices in many different ways, but in other ways things are simpler today because nearly all network communications are built on top of the foundation of Ethernet and TCP/IP. This session will take a look at these foundation Ethernet and TCP/IP and how they are built up within the IBM i OS. We will look at your communications adapters, Line Descriptions, and IP addresses, subnets, routes and more including the commands and interfaces used to manage these. We will also look at some of the most commonly used networking servers like Telnet and FTP and cover their basics of configuration, management and even troubleshooting.

Network Communications security is a necessity for nearly everyone in at least some scope, and this session will look at some of the technology and tools available on the IBM i OS TLS network encryption is a very important part of the security picture, and we will look at some protocol details, managing the communications network encryption environment on your IBM i OS, differentiating what is available and how the configuration approach differs at the differing IBM i OS releases, and what is the latest coming in the TLS encryption protocol. We will also briefly look at sniffer traces showing different connection handshakes. Depending on available time we may also look at other Networking Security topics like Intrusion Detection, IP Filtering & NAT with Packet Rules and VPN.

Learning Objectives:

1. This session will allow the participant to understand the Transport Security topic terminology and implementation better
2. How to manage the Transport Security environment on the IBM i OS
3. Knowledge of other IBM i OS Network Security topics.

Your IBM i OS Networking health is very important and is it how most of your data and applications are accessed. This session will take a look at approaches to monitoring this IBM i OS Networking health and it's interaction with the network, how to collection diagnostic data and how to troubleshoot problems.

FTP - everyone uses it, but what is it and how does it work?? This session addresses techniques for making the most of the FTP client on the system: how to trouble shoot common network problems associated with FTP; creating scripts; adding notes to results; evaluating success of transfers; how to create a dynamic script for file transfers using sample programs included in the handouts; and addressing security concerns.
New for 2019: finally an easy solution to doing SSH FTP!

Learning Objectives:

By the end of this session, attendees will be able to:
1.Describe the network interactions related to FTP Manage FTP transfer scripts
2. Programmatically handle results of transfers
3. Use FTP scripts with substitutable values
4.Identify potential security hazards and ways to handle them
5. Identify people who read all learning objectives
6. Be familiar with IBM i open source support
