Accessing Shared Devices
18
This chapter uses an example to demonstrate how to configure the PortMaster to
connect from networked hosts to shared devices attached to the PortMaster. This type of
connection provides user access to modems, printers, and other RS-232 devices.
The following topics are described:
• “Overview of Shared Device Access Methods” on page 18-1
• “Configuration Steps for Shared Device Access” on page 18-4
See the
PortMaster Command Line Reference
for more detailed command descriptions and
instructions.
Overview of Shared Device Access Methods
Use one of the following methods for providing access to shared devices on the
PortMaster:
• Host device configuration
You use a UNIX host that supports the PortMaster in.pmd daemon. With this
daemon, you can configure ports as host devices and access them as pseudo-tty
terminals from the host using the tip command, UUCP, and other applications.
• Network device configuration
You configure the ports as network devices and access them via Telnet, rlogin, or a
clear channel TCP connection (netdata).
Host Device Configuration
One function of a communications server is to provide network users with access to
shared devices such as printers and modems. This access can be provided if the port
connected to the printer or modem is configured as a host device port. This
configuration is also useful for tip and UUCP services.
