TCP/IP Implementation on z/OS

Prerequisites:

Delegates are expected to be familiar with:
TCP/IP, which may be obtained from our Understanding TCP/IP course.
z/OS, which may be obtained from our z/OS for Beginners course.
TSO/ISPF, which may be obtained from our TSO/ISPF workshop course.
UNIX Services on z/OS, which may be obtained from our Introduction to UNIX Services on z/OS course.
General UNIX user facilities, which may be obtained from our UNIX The Essentials course.

Course Description:

The course will provide delegates with detailed implementation plan for the implementation of TCP/IP. During which they will be involved with exercises which involve configuring a TCP/IP stack on z/OS including a network interface, telnet and ftp.

This course is designed for system programmers who will be responsible for implementing TCP/IP on z/OS.

This course includes the following modules:
