    USAGE:  netware-worms [cpus|speedup]
        i.e. worm cpus=<num=8 to 256> speedup=<divisor=1|2|3|4>
    examples:
        netware-worms cpus=8;
           start worm screensaver with 8 worm threads
        netware-worms speedup=4
           run worm screensaver at 4X speed

This screensaver is built as both a dynamic shared object (*.so) and
static archive (*.a) library module which allows other user space
programs and consoles to invoke this screen saver as well as tmux,
screen, and other BASH type programs setups.

This screensaver uses ncurses and is text based which is identical to
the Novell Netware SMP multi processor screensaver which displayed a
color coded worm for each processor running. As each processor load
increases on a particular processor, the longer the worm becomes and the
faster it moves across the screen corresponding to that particular
processor. As the overall system load average across the system
increases, the base clock rate for all the worms increases slightly to
indicate load average is increasing.


Quick Start Guide

You can download precompiled RPM packages and Debian (DEB) packages from
the release page for this project, or you can build the program from the
git sources.

If you want to build the program from scratch with the git sources
rather than use the pre-compiled RPMS and DEB packages, then please skip
to the section Building the Screensaver from Source for instructions on
how to do this.

Packages are provided in binary and source versions, and can be
downloaded and installed directly or rebuilt for a different target
architecture such as ARM64. Package types are Red Hat Package Manager
(RPM) packages and Debian (DEB) packages for binary installation and
Source RPM packages (SRPMS) and Debbuild SDEB packages for source code
installation.

RPM and DEB packages for each release include a binary architecture
specific package and a source package which can be downloaded and
built/rebuilt and which contains the source code.

For example, the release v1.21 contains the following packages in the
release section:

RPM BASED PACKAGES (REDHAT, CENTOS, SUSE)

-   netware-screensaver-1.21-1.el8.src.rpm
-   netware-screensaver-1.21-1.el8.x86_64.rpm

DEBIAN BASED PACKAGES (DEBIAN, UBUNTU)

-   netware-screensaver-1.21-1.sdeb
-   netware-screensaver_1.21-1_amd64.deb

INSTALLING BINARY PACKAGES

To install the binary package with the rpm package manager for x86_64:

    rpm -i netware-screensaver-1.21-1.el8.x86_64.rpm

To deinstall the RPM binary package:

    rpm -e netware-screensaver

To install the binary package with the Debian dpkg package manager for
amd64:

    dpkg -i netware-screensaver_1.21-1_amd64.deb 

To deinstall the Debian dpkg binary package:

    dpkg -r netware-screensaver

INSTALLING SOURCE PACKAGES

To install the source package with the rpm package manager:

    rpm -i netware-screensaver-1.21-1.el8.src.rpm

_(Note: rpm installs the source code files in /root/rpmbuild/ as top
directory for RedHat and CentOS platforms. SuSe platforms install the
source code files in /usr/src/packages/)_

To install the source package with the Debbuild package tool:

    debbuild -i netware-screensaver-1.21-1.sdeb

_(Note: Debbuild installs the source code files in /root/debbuild/ as
top directory)_

For building or rebuilding RPMS or DEB Packages after you have installed
the associated source packages on your platform, refer to the following:

-   Building the Screensaver as an RPM Package (Redhat/CentOS/SuSe)
-   Building the Screensaver as a Debian Package (Debian/Ubuntu)


Building the Screensaver from Source

You must have the ncurses-devel packages installed in order to make
ncurses apps on your system. you can try “dnf install ncurses\*” to get
all of the ncurses packages for RedHat and CentOS systems. This version
was developed on a Red Hat 7 / CentOS 7 system.

to make, type:

    make -f Makefile <enter>

the build process should display:

    g++ -g -c -O3  -fPIC -Wall libnetware-screensaver.c 
    ar r libnetware-screensaver.a libnetware-screensaver.o  
    ar: creating libnetware-screensaver.a
    ld -shared -lc -o libnetware-screensaver.so libnetware-screensaver.o  
    g++ -g -O3 netware-worms.c libnetware-screensaver.a -Wall -o netware-worms -lncursesw -lpthread -ltinfo

to perform a clean build:

    make -f Makefile clean <enter>

should display:

    rm -rf *.o libnetware-screensaver.a libnetware-screensaver.so netware-worms


Installing and Uninstalling the Screensaver from Source

To install:

    make -f Makefile install <enter>

should display:

    install -m 0755 netware-worms /usr/bin
    install -m 0755 libnetware-screensaver.so /usr/lib64
    install -m 644 libnetware-screensaver.a /usr/lib64
    install -m 644 netware-worms.h /usr/include
    ldconfig
    ldconfig

To uninstall:

    make -f Makefile uninstall <enter>

should display:

    rm -vf /usr/bin/netware-worms
    removed '/usr/bin/netware-worms'
    rm -vf /usr/lib64/libnetware-screensaver.so
    removed '/usr/lib64/libnetware-screensaver.so'
    rm -vf /usr/lib64/libnetware-screensaver.a
    removed '/usr/lib64/libnetware-screensaver.a'
    rm -vf /usr/include/netware-worms.h
    removed '/usr/include/netware-worms.h'
    ldconfig
    ldconfig


Running the Screensaver

you can execute the program directly as:

    ./netware-worms <enter>

you can also add arguments to force number of cpus and a speedup divisor

    ./netware-worms cpus=8 speedup=4 <enter>


Installing the Screensaver in the Bash Shell

To install the screensaver as a bash program which auto activates, use
the program called “screen” coupled with Bash. The “screen” program has
support for adding and invoking terminal based screensavers under Bash.

You can install the program on CentOS and RHEL with dnf by typing “dnf
install screen” if the program is not installed by default. On Debian
based systems you can install the program with “apt-get install screen”.

Red Hat based systems can use yum or dnf to install the screen files:

    dnf install screen 

Debian based systems can use apt or apt-get to install the screen files:

    apt-get install screen 

You should also install at the same time the terminfo and termcap files
to support the “screen” terminal type for ncurses to avoid getting
“unknown terminal type” errors when attempting to log into the system
over ssh.

Red Hat based systems can use yum or dnf to install the terminfo files:

    dnf install ncurses-term 

Debian based systems can use apt or apt-get to install the terminfo
files:

    apt-get install ncurses-term 

You will need to create a .screenrc file in the user home directory
(i.e. ~/.screenrc) which contains the following commands:

SAMPLE ~/.SCREENRC FILE

    blankerprg netware-worms
    idle 60 blanker

Please note the idle command which specifies how many seconds to delay
before invoking the screensaver (in this example it is 60 seconds)

You also need to modify the ~/.bash_profile default bash configuation
file to invoke screen by default after login. Add the /bin/screen
command to the end of the ~/.bash_profile config file:

SAMPLE ~/.BASH_PROFILE

    # .bash_profile
    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
        . ~/.bashrc
    fi
    # User specific environment and startup programs
    PATH=$PATH:$HOME/bin
    export PATH
    /bin/screen  

It must be the last line in the file since following login, the
/bin/screen program will be executed and run as a transparent bash
shell.

After you have configured these two files, logout and log back into the
system for whichever account you have enabled and the screensaver will
auto-activate after 60 seconds of idle time. The only disadvantage to
using this method to enable a terminal based screensaver is you will
need to type the “exit” command twice in order to logout of the session.


ssh client returns unknown terminal type when remotely logging into the system

Some older CentOS and Red Hat Enterprise Linux distributions do not
properly detect or parse aliased terminal types such as
“screen.xterm-256color” when using ssh to remotely access a system that
has screen installed and running. This results in an “unknown terminal
type” error being returned after logging in. This error can be fixed by
changing the ~/.bashrc file for the affected account and add a check for
the term type, then export a terminal type that matches one of the
supported terminal types in the ncurses-term package.

Add the following to the bottom of the .bashrc file to check the
terminal type, then change and export it if necessary.

    if [[ "$TERM" == "screen.xterm-256color" ]]; then
       export TERM=screen-256color
    fi

The “screen.xterm-256color” terminal type is the most common terminal
type seen when this ssh error occurs and it is caused by the ncurses
library terminfo and termcap files either not being installed or
improperly configured.

If you encounter this error and are running on version CentOS/RHEL 7 or
earlier, then edit your .bashrc file to append the terminal type and
remap check as shown in the example below:

SAMPLE ~/.BASHRC

    # .bashrc
    # User specific aliases and functions

    alias rm='rm -i'
    alias cp='cp -i'
    alias mv='mv -i'

    # Source global definitions
    if [ -f /etc/bashrc ]; then
        . /etc/bashrc
    fi

    # add the following 3 lines to the end of the .bashrc file  
    if [[ "$TERM" == "screen.xterm-256color" ]]; then          
       export TERM=screen-256color                              
    fi                                                         


Using Libraries

You can also call the screensaver as a library function
“netware_screensaver(cpus, speedup)” from another application with your
own timer setup, just be sure to link to the “-lnetware-screensaver” .so
library in your linker statements or link to the static library
“libnetware-screensaver.a”


Building as an RPM Package

In order to build the screensaver as an RPM, the program must be
compressed into a tar.gz file and the tar.gz file named to match the
versioning information contained in the associated .spec file.

Spec files are special files which contain instructions on how to build
a particular package from a source code archive. On Red Hat and CentOS
systems, RPMS are built in the /root/rpmbuild/ top directory. SuSe
systems build RPMS in the /usr/src/packages/ as top directory. These
“top directories” will contain BUILD, BUILDROOT, SPECS, RPMS, SRPMS, and
SOURCES subdirectories.

The SPECS directory contains the *.spec files used to build RPMS and
SRPMS packages. The SOURCES subdirectory will contain the soure code
archive file referred to in the *.spec file used to build the RPM
package.

See the Quick Start Guide on instructions for installing the source rpm
which installs both the .spec file and source archive file (tar.gz) into
the rpm build top directory (i.e. /root/rpmbuild/). You should have
previously installed the src.rpm file before attempting to build the
rpm. You can also manually install the .spec file into the <top
directory>/SPECS/ directory and the source code tarball in the <top
directory/SOURCES/ directory, then attempt to build the rpm package.

To build the Screensaver using the rpm tool, change directories (cd)
into the /root/rpmbuild/SPECS/ directory (/usr/src/packages/SPECS/ for
SuSe) and enter the following command:

    rpmbuild -ba netware-screensaver.spec <enter>

The program should output the following if the build is successful and
verify that the program wrote both the RPMS and SRPMS packages:

Building as a Debian Package

In order to build the screensaver as a Debian package, the program must
be compressed into a tar.gz file and the tar.gz file named to match the
versioning information contained in the associated .spec file. Spec
files are special files which contain instructions on how to build a
particular package from a source code archive.

Debian Packages can be built using a utility called “debbuild” and use a
top directory structure which is similar to that used by the RPM tool
but using /root/debbuild/ as the “top directory”. These “top
directories” will contain BUILD, BUILDROOT, SPECS, DEBS, SDEBS, and
SOURCES subdirectories and follows a similar layout that is used for RPM
files.

The SPECS directory contains the *.spec files used to build DEB and SDEB
packages. The SOURCES subdirectory will contain the soure code archive
file referred to in the *.spec file used to build the DEB and SDEB
packages.

See the Quick Start Guide on instructions for installing the source SDEB
which installs both the .spec file and source archive file (tar.gz) into
the debbuild top directory (i.e. /root/debbuild/). You should have
previously installed the SDEB file before attempting to build the DEB
package. You can also manually install the .spec file into the <top
directory>/SPECS/ directory and the source code tarball in the <top
directory/SOURCES/ directory, then attempt to build the DEB package.

To build the Screensaver using debbuild, change directories (cd) into
the /root/debbuild/SPECS/ directory and enter the following command:

    debbuild -vv -ba netware-screensaver.spec <enter>

The program should output the following if the build is successful and
verify that the program wrote both the DEB and SDEB packages:

    This is debbuild, version 22.02.1\ndebconfigdir:/usr/lib/debbuild\nsysconfdir:/etc\n
