If gzip is not present on your system, you can download it from the same site

www.sunfreeware.com and install it using

# pkgadd –d gzip-1.3.5-sol8-sparc-local

Please note, that the name may be slightly different. Then change to super user mode

by invoking the su command and type

# pkgadd –d sudo-1.6.7p5-sol8-sparc-local

The sudo package now installs to /usr/local system folder. You can now proceed

to the installation of pwdch.

5.2 PWDCH Installation

We recommend the pwdch password service utility to be installed by root to the

/usr/local folder. This may be performed by saving the tarball pwdch.tar to the

/usr/local folder and typing the command

# tar -xvf pwdch.tar

A new subfolder /usr/local/cms is created containing a shell script pwdch, two

executables pwdch_normal, pwdch_arrow and one example file example_passwd.

You may now safely remove the tarball with

# rm pwdch.tar

to finish the installation. If you desire to choose an alternate destination, you may do so

as there is no requirement from the application to be executed in a specific directory

except the program path defined in the shell script pwdch. You may easily change it

using a text editor such as

vi.

A second executable pwdch_arrow has been provided, as in some rare situations the

curses color settings are not properly reconstructed by certain terminal emulators. In

that case the selection bar stays invisible and the application becomes unusable. You

might then decide to use pwdch_arrow instead of pwdch_normal, as it does not rely

on coloring to provide a selection marker, it merely uses standard character to

resemble an arrow. We have never encountered that effect with AVAYA terminal

emulation applications. You may easily toggle between pwdch_normal and

pwdch_arrow without altering the entire configuration by modifying the startup script

pwdch.

5.3 SUDO Configuration

In order to allow pwdch to run in super user mode, sudo has to be configured properly.

This is achieved by changing to root using the su command and executing

# visudo

Do not attempt to change the /usr/local/etc/sudoers file manually as this

bypasses the syntax checker and may corrupt operation. In order to use visudo, you

should be confident with the vi editor. If you desire to change the default editor, please

consult the sudo documentation. To give a trusted user root access to pwdch, enter

the following line in the section >>User priviledge specification<<

<user> ALL=(root) NOPASSWD:/usr/local/cms/pwdch
