Telnet

Telnet is a protocol that allows you to log onto and use a remote computer as though you were connected directly to it within the local network.

The machine (usually a PC), or system that you are physically in front of is the Telnet client. The Telnet server is the remote computer to which the client is attached. IBM^® eServer™ iSeries™ TCP/IP supports both the Telnet client and server.

One of the most important Telnet functions is its ability to negotiate the transmission of data streams between the Telnet client and the server. This type of negotiation makes it possible for either the client or the server to initiate or honor a request.

Several different emulation types are available for negotiating requests and converting them to output. For iSeries Telnet, the preferred type is 5250 emulation. iSeries Telnet also supports 3270, and VTxxx type workstations as well as RFC 2877 (TN5250E) printer support modes. This topic introduces Telnet and provides you with information to help you administer Telnet on your iSeries server.
