as well as some information about the port.

# This utility is used to list all of the open ports on a Solaris UNIX
# based machine. It relies heavily on tools that are used to read through
# the /proc directory so it needs to be run as root or as a root equivalent.
#
# The pathname for all executables should reside in root's path statement
# for ldd to work correctly with this script

#
# nmap is a great tool that will show you what is listening on each port
# of a given machine.
#
# nmap tries to give you some information about each port that it finds.
# It does not assume that any service is listening on any port number and
# it will tell you what is listening on the port if it is told to do so
# and it is able to do so.
#
# However, I felt that the information that was given to me via nmap still
# left a lot of research to do on each port so I threw a script together
# to tell you what process is listening on each port and to give you some
# more information about the process so you can tell at a glance what is
# happening on the system that you are responsible for.
#
# Enjoy the script.
