how to monitor ports

I run into this issue occasionally and just looking for suggestions on how others solved it. I would like to monitor ports on a large number of systems and would like to determine which systems are listening on specific ports. I know there are heavy-weight apps that provide this such as HP ovo but I am looking for some light-weight open source options. I believe a syn scan will be sufficient for my purpose but I have not used any tools previously or not sure if their is a way to use default system tools or commands for this. Also for the those that have used syn scanning, does anyone run into issues due to simulating a syn attack in any of your networks?

Before you relpy, please do not recommend ping as it does not provide the functionality that I am looking for. Also, telnet will not provide this functionality because I do not what to have to script any break out or termination sequences for various connections (ie sendmail - port 25).

NAME

       hfsplus -- a set of tools to access HFS+ file systems

Description
       HFS+,  also  known  as  the Macintosh Extended Format, was introduced by Apple Computer in 1998 with the release of MacOS 8.1.  It contains
       many improvements over the old HFS file system, most notably the ability to allocate up to 2^64 blocks, resulting in  much  more  efficient
       storage of many small files on large disks.

       The  hfsplus  collection  allows to access volumes formatted with the HFS+ file system from Debian GNU/Linux and related operating systems.
       The collection contains tools to mount and unmount HFS+ volumes, to change and list directories, and to copy files to and  from	HFS+  vol-
       umes.

       Note  that unlike its cousin, the hfsutils collection used for accessing HFS file systems, hfsplus does not use the Macintosh pathname syn-
       tax with ":" as delimiter.  Instead, it mimicks the unix notation, delimiting the names of volumes, directories and files in  a	path  with
       "/", and also understands "." and ".." to some extent.

Author
       This  manual  page  was	written by Jens Schmalzing <jensen@debian.org> for Debian GNU/Linux using the manual page by Klaus Halfmann <half-
       mann@libra.de> that comes with the source code and documentation from the Tech Info Library.
