DCMI - System i/ iSERIES/ AS400 Q & A Answers

You need to configure TCP/IP. This is well covered in the TCP/IP Configuration and Reference manual (SC41-3420), however we will try to get you started on the right foot. TCP/IP consists of applications that allow you to exchange documents, files, and e-mail with other users, and the underlying communications infrastructure necessary to enable you to exchange data within your own network, as well as across other networks.

How do I decide what TCP/IP applications I need? Here is a brief description of the applications you may want to enable on iSeries 400:
  • Telnet Client and Server
    The telnet server allows users from other workstations (pc's, terminals connected to other hosts) to establish a terminal emulation session. The telnet client allows connected users to establish terminal emulation sessions on other hosts, similar to display station passthru.

  • FTP Client and Server
    The FTP server allows users from other workstations to retrieve files from iSeries 400. The FTP client allows users to retrieve files from other computers. For example, I can retrieve source files and update then on my PC, then send the updated files back to iSeries 400.

  • SMTP and POP3
    SMTP (Simple Mail Transport Protocol) and POP3 (Post Office Protocol) allows iSeries 400 to exchange mail with internal as well as external users. For example, your OV/400 users can exchange e-mail with most any other user, over the Internet.

  • HTTP Server
    HTTP (Hyper Text Transfer Protocol) enables iSeries 400 to serve requests from web browsers, including static html documents, or dynamic documents enabled thru the cgi-bin programming interface, or Net.Data.

  • LPR and LPD
    LPR (line printer requester), implemented via the sndtcpsplf OS/400 command, allows spool files to be sent to other hosts or network printers. LPD (line printer daemon) allows the iSeries to receive print files from other hosts, similar to the RCVNETSPLF OS/400 command.
