Telnet is a terminal emulation protocol. With Telnet, users can
log on to remote host applications as though they were directly attached
to that host. Telnet protocol requires that the user have a Telnet
client that emulates a type of terminal that the host application
can understand. The client connects to a Telnet server, which communicates
with the host application. The Telnet server acts as an interface
between the client and host application. A PC can support several
clients simultaneously, each with its own connection to any Telnet
server. This topic describes how to set up and use the following kinds
of Telnet servers:
- TN3270E Telnet server
Provides access to z/OS® VTAM® SNA
applications on the MVS™ host
using Telnet TN3270E, TN3270, or linemode protocol
- z/OS UNIX Telnet server
Provides access to z/OS UNIX shell
applications on the MVS host
using Telnet linemode protocol
You can use the same port for both Telnet servers. For an overview
of port management, see
Port management overview.
