R2511-HP MSR Router Series Terminal Access Configuration Guide(V5)

Installing and configuring an FEP

To implement terminal access with an FEP as the receiver, the router-side program serving as the initiator

must work together with the FEP-side programs serving as the server that receives connection requests

from the initiator. This chapter covers the installation, configuration, operation, and management of

FEP-side programs.

Normally, an FEP runs the following two programs:

• ttyd (ttyd executable) program, which is the main program running at the FEP side in terminal

access. It exchanges data with the router-side program.

• ttyadm terminal administration program, consisting of two executables: ttyadmcmd and ttyadm.

This program manages the ttyd program.

A Unix FEP supports up to 256 terminals. A Linux FEP supports up to 4096 terminals.

Installing and configuring SCO OpenServer server

Installing device drivers

You can choose to install device drivers using a floppy disk, FTP, or the installation program.

Using a floppy disk

The following describes the installation procedure using a floppy disk.

1. Switch to a console terminal.

To install the ttyd program, you need at least one console terminal. In SCO OpenServer Unix, use

a hotkey from Alt+F1 to Alt+F12 to switch between console terminals.

2. Log in as a superuser such as root.

To install and configure this program, you must log in as a superuser as follows:

a. Press a hotkey to switch to a console, Alt+F4 for example. The following interface appears:

SCO OpenServer(TM) Release 5 (scosysv) (tty04)

b. At the prompt of "login:", enter root. Then, at the prompt of "Password:", enter the password

root. Then, you can log in to the Unix server as root.

3. Install the drivers.

Insert the floppy disk into the floppy drive of the Unix server and then run the mount command to

mount the floppy drive.

# mount /dev/fd0 /mnt

Copy the executable files to the Unix server.

# cp /mnt/ttyd /etc/ttyd

# cp /mnt/TTYADMCMD /etc/ttyadmcmd

# cp /mnt/TTYADM /etc/ttyadm

Change the file mode of the files to executable mode.

# chmod 744 /etc/ttyd /etc/ttyadm /etc/ttyadmcmd
