Book description

Building on the cool ideal, this IBM® IBM Redbooks publication describes V5 enhancements to many of the TCP/IP applications. The two book predecessors, combined, have been downloaded over 97,000 times: for V3, Cool Title About the AS/400 and Internet, SG24-4815-01, and V4 TCP/IP for AS/400: More Cool Things Than Ever, SG24-5190-00. Both of these extremely popular books are “aggregators” — a place to bring together many different technologies all in one place to have a common theme; teach the basics. That is, teach what the functions can do, define scenarios, and then implement the scenarios in a how-to fashion. Many of the topics covered in those earlier books, such as HTTP, Digital Certificates, and even TCP/IP have grown to the point now that they require their own Redbooks™ . In this book, we cover Telnet, FTP, IPP, NTP, SMTP, and making VPN connections with the iSeries™ , to and from the Internet.

Please note that the additional material referenced in the text is not available from IBM.
