Do you have the responsibility for TCP/IP problem resolution? When you get a trace, are you clear on what it can tell you or are you mystified? Do you want to brush up on how exactly the core Internet protocols (TCP, IP, UDP and ICMP) work? Can you tell if you have implemented your TCP profile parameters properly from traces? How about the major applications? Do you understand how FTP, Telnet, MQSeries, HTTP or LDAP work?

We will spend much of the time in this class in labs reading trace after trace (TCP, UDP, ICMP, LDAP, MQSeries, Websphere, HTTP, etc) showing various aspects of the core Internet protocols and applications, both in normal situations and in abnormal. The more experience you have with traces, the more you will become comfortable and adept at resolving many problems in the TCP/IP network. We will use case studies from real situations to see how such problems manifest themselves and have been resolved.

Do you have the responsibility for TCP/IP problem resolution? When you get a trace, are you clear on what it can tell you or are you mystified? Do you want to understand how the core Internet protocols (TCP, IP, UDP and ICMP) work?

This class will do labs and exercises to understand the concepts shown. Sample syllabus for TCP:

• How does the TCP open sequence work?
• Lab: Read traces with the TCP open sequence for TN3270, CICS, WebSphere, FTP, etc.
• Negotiating and setting MTU, window and other parameters in the open sequence
• Data transmission implementation in the TCP protocol
• How does TCP congestion window work?

How do TCP applications really work? Often problems happen, not at the protocol layer, but in the application. Do you understand how HTTP, FTP, DNS, LDAP, Enterprise Extender, SNMP, MQSeries and other major applications work? When there are problems, do you know where to look? What are the common problems which occur for each application? The more you understand about how each layer impacts the other, the more effective and successful you will be as a diagnostician.

This class will do labs and exercises to understand the concepts shown. Sample syllabus for TCP applications:

• Hypertext Transfer Protocol (HTTP) Introduction
• HTTP: Architecture, troubleshooting, performance, security
• Lightweight Directory Access Protocol (LDAP) Introduction
• LDAP: Architecture, troubleshooting, performance, security
• File Transfer Protocol (FTP) Introduction
• FTP: Architecture, troubleshooting, performance, security
• MQSeries Introduction
• MQSeries: Architecture, troubleshooting, performance, security
• Case studies

TCP/IP Performance Management, Security, Tuning, and Troubleshooting on z/OS: Face to face class: $2,350

Do you have the responsibility for TCP/IP performance management? Are you unsure of where to start? Or do you want to brush up on your monitoring, analysis, and tuning skills? Does your TCP/IP network need a performance check-up? Do you need to know how to establish a practical performance management program for your TCP/IP stack and socket applications?

For many problems in the TCP/IP network, the only symptom is poor response time. In this class you will learn the many factors which may be responsible for response time and throughput issues.

Consider this week long class as being dedicated to analyzing your system performance with input and recommendations from your own performance expert.

SSL, AT-TLS and IPSec Implementation and Diagnostics: Face to face class: $2,350

Do you have the responsibility for implementing security for TCP/IP? What options are available? You may have heard of IPSec, Secure Sockets Layer, Virtual Private Tunnels or Intrusion Detection Services. What implementation pitfalls will you run into? Would you like to have some hands-on experience? Would you like to see trace packets using such protocols?

What about network cryptography? One of the most critical portions of IPsec and SSL is the initial negotiation (SSL handshake or ISAKMP). These negotiations rely on public / private key encryption and Diffie-Hellman key exchange. How do these really work?

In this class, we will understand:

• Asymmetric encryption / symmetric algorithms
• Public key / private key encryption
• Diffie-Hellman key exchange / groups
• ISAKMP phase 1 and phase 2 negotiation
• Packet flow for ISAKMP
• SSL handshake
• SSL troubleshooting

We will actually implement Policy Agent, SSL, AT-TLS, and IPSec (TRMD and IKED) on z/OS. Then, trace flows! To view the full class description, please click on Face to Face Security Class Description. For dates see the SSL Class Schedule above.

SSL and AT-TLS Implementation: Web based class: $500

Do you have the responsibility for implementing secure sockets for TCP/IP? What options are available? What is the difference between SSL and AT-TLS? What implementation pitfalls will you run into? Would you like to have some hands-on experience? Would you like to see Policy Agent implemented? Would you like to see trace packets using SSL?

In this class, we will do:

• Live demo: implementation of Policy Agent
• Live demo: implementation and use of z/OS Configuration Assistant
• Live demo: implementation of SSL on z/OS
• Live demo: implementation of AT-TLS on z/OS
• Live demo: RACF authorizations
• Live demo: Creation of certificates and storing in RACF
• SSL handshake
• SSL troubleshooting

We will actually implement SSL and AT-TLS on z/OS. Then, trace flows! To view the full class description,please click on Web SSL/AT-TLS Class Description.. For dates see the SSL Class Schedule above.

Introduction to IPv6: Face to face class: $2,500

The American Registry for Internet Numbers (ARIN) has run out of IPv4 addresses. Microsoft Vista is enabled for IPv6 'out of the box'. The transition to IPv6 seems inevitable in the next few years.

In this class, we will enable IPv6 on our router and z/OS TCP stack, Windows XP, and Linux. As always, there is nothing like hands-on experience! We will also trace packets on the IPv6 networks and deeply understand the protocol.

In class, we will also examine migration scenarios:

• Dual stack mode (IPv6 / IPv4)
• Tunneling (Manual, GRE, GRE with IPSec, 6to4, Teredo)
• Translation (NAT-PT, SIIT)
• Application changes

To view the full class description, please click on Face to Face IPv6 Class Description. For dates see the IPv6 Class Schedule above.

Do you want to start to understand IPv6 from a technical viewpoint? IPv6 is much more than a larger address. Many features of the IPv4 protocol have been replaced. Address planning and structure is completely different. Much of what you know for IPv4 needs to be rethought. For example, ARP has been replaced with Neighbor Discovery. NAT does not exist in IPv6 – or does it? We will review address planning for IPv4 and then consider how we might do that in IPv6. We will also briefly discuss application changes.

In this class, we will look at:

• IPv6 on z/OS, Windows, Linux and routers
• Tunneling (Manual, GRE, GRE with IPSec, 6to4, Teredo)
• Address planning for IPv4 and IPv6
• Application changes

To view the full class description, please click on IPv6 Class Description. For dates see the IPv6 Class Schedule above.

Do you want to implement IPv6 on your z/OS system? Watch us do the commands to change the configuration files (BPXPRMxx, TCP Profile, etc) and then re-IPL! You can follow along on a test system and do the same commands that we do! If you don't have access to a master console, then just watch as we do it. Nothing is as good as live experience. This is a complete lab class.

In this class, we will do:

• Enable IPv6 sockets,
• Configure IPv6 in the TCP Profile,
• Define IPv6 interfaces,
• Define routes,
• Log on to our new system, and
• Take IPv6 traces,

Hands-On Enterprise Extender Trace Analysis: Face to face class: $2,000

Many companies are implementing Enterprise Extender. Diagnosing problems and reading a trace with EE packets is a challenge! Problems occur when first implementing EE and establishing connections – you need to understand exactly how to decode the XID and Path Switch segments. Then, once EE is implemented, do you know how well it is working? We have seen companies with over half their RTP Pipes (virtual circuits) unused, yet transmitting overhead traffic.

This is a hands-on class. We will actually implement Enterprise Extender in a lab environment between z/OS (on a laptop) and PCOM. This will allow us to trace flows and issue commands. We will spend much of the time in this class in labs reading trace after trace examining the behavior of Enterprise Extender in normal situations and in abnormal. The more experience you have with traces, the more you will become comfortable and adept at resolving many problems in the TCP/IP network. We will use case studies from real situations to see how such problems manifest themselves and have been resolved.

The prerequisite to this class is the TCP/IP Trace Reading and Troubleshooting on z/OS course
