TELNET client and server
REXEC client and server
TCP/IP is an extremely popular protocol that is regarded as the de facto standard
for computer networking. TCP/IP is fundamental to the network computing
paradigm and helps make the iSeries an even more powerful on demand
business server. Much of the iSeries on demand business infrastructure runs
exclusively on TCP/IP, including Lotus Domino, Java, WebSphere, Web serving,
and IBM Network Stations.
The TCP/IP communication protocol function, along with related administration
and configuration support, are packaged with OS/400.
TCP/IP Connectivity Utilities (5722-TC1) is automatically shipped to all
customers that order OS/400. TCP/IP applications shipped as part of the TCP/IP
Utilities include TELNET, SMTP, FTP, Remote Execution (REXEC) Server, and
LPR/LPD (remote print support).
For a full description of TCP functions and features, refer to the Networking -
TCP/IP section of the iSeries Information Center, and IBM Eserver iSeries IP
Networks: Dynamic!, SG24-6718.
HTTP Server for iSeries (5722-DG1)
HTTP servers are the core foundation of technology at the heart of all on demand
business applications. They handle the communication with the client (typically
browsers or Extensible Markup Language (XML)-rendering devices such as
personal digital assistant (PDAs)) and provide the entry point into server
resources. These resources can range from simple Hypertext Markup Language
(HTML) and GIF files, to on demand business and e-commerce applications, all
the way to complete business-to-business, collaborative enterprises.
For the iSeries servers, network computing is supported with HTTP Server for
iSeries. An iSeries server can access a vast network of computers as though
they were a single entity. Everyone and everything can access and distribute
information, applications, and services provided by the network.
Based on the popular Apache 2.0 open-source software, the HTTP Server
(powered by Apache) is the IBM strategic HTTP server. Multiple HTTP servers
can be active simultaneously on a single iSeries.
