Chapter Configuring and Managing Telnet Servers

Chapter 13 Configuring and Managing Telnet Servers

Overview

Introduction

This chapter explains how to configure various types of devices as a Telnet or raw TCP server. A Telnet or raw TCP server is a resource on a TCP/IP network.

To use the procedures in this chapter, you must:

∙Connect and test the devices

∙Enable privileged status

∙Configure the port and device characteristics to match

Refer to your access server hardware documentation for information about connecting device cables.

In This Chapter

This chapter contains the following topics:

∙Sample Device Configurations

∙Configuring a Personal Computer As a Terminal and for Access through a Telnet Listener

∙Configuring a Remote Print Queue

∙Configuring a Telnet Listener

∙Configuring Telnet Server Session Characteristics

∙Managing Your Access Server As a Telnet Listener Node

∙Supplying User Location Data to Telnet Servers

∙Configuring a Raw TCP Listener
