4 On the Unix server, change the file modes of the programs to the executable
mode.
# chmod u+x /etc/ttyd /etc/ttyadm /etc/ttyadmcmd
Now, the ttyd, ttyadmcmd, and ttyadm programs are installed.
Using the installer
For the SCO OpenServer Unix system, make sure you have a standard program
installation CD supporting this system. You can use the installation program
named VOL.000.000 on the disk to install the ttyd, ttyadmcmd, and ttyadm
programs to your SCO OpenServer Unix server. The installation procedure is as
follows:
1 Copy the installation file VOL.000.000 to a directory on the SCO OpenServer Unix
server. The following example assumes that the installation file is copied to the
directory /build. Type scoadmin to open the SCO manager.
2 From [FileSoftware Manager], select [SoftwareInstall New...] to enter software
installation interface, and then select local installation.
3 Select [Media Images] for Media Device.
4 In [Image Directory], enter the directory holding the installation file (this example
assumes VOL.000.000 is placed in the directory /build). Press <Enter>, and
information about the programs under the directory that can be installed will be
listed, such as "ttyd for sco openserver 5.05".
5 Select [Install] to start the installation. After the programs are installed, a message
of "OK" is displayed.
Now, the ttyd, ttyadmcmd, and ttyadm programs are all installed.
Configuration Before configuration, you must determine the mappings between pseudo
Prerequisites terminals on the Unix server and ports on the router.
If the Unix system is connected with many terminals, the required resources may
exceed the default of the Unix system. In this case, you must modify the kernel
parameters of the Unix system.
The method for modifying the kernel of the SCO OpenServer Unix system is as
follows:
Adding pseudo terminals
By default, SCO OpenServer Unix supports up to 64 pseudo terminals. To connect
to more terminals, you must add pseudo terminals on the Unix system.
Before adding pseudo terminals, you must check whether the pseudo terminals
exist. For example, you can use the following command to check whether
