BashScriptToFindPortsUsed
From MLDonkey
Which TCP or UDP ports are opened by MLDonkey ?
Maybe you're looking for which ports are opened by MLDonkey?
This small bash script will try to find and display TCP and UDP ports by parsing MLDonkey's configuration files.
How to use this script ?
- Open your favorite editor and copy/paste the code below.
- Edit the var "BASEDIR=" to point to where MLDonkey stores its configuration files.
- Do a _chmod u+x_ to make the script executable.
- Execute the script :)

# Changelog:
# * Sun Nov 29 2009 - v0.4
# - Attempt to find the MLdonkey installation, or let them specify it
# in the BASEDIR variable on the command line.
# - Rewrite checkNetwork() and findPort() for efficiency and handling
# of newer version of MLDonkey.
#
# * Sun Aug 08 2004 - v0.3
# - Added an error message when the network configuration file exist
# but no port number was found.
#
# * Sat Aug 07 2004 - v0.2
# - Bugfix, ${BASEDIR} was missing when calling the findPort() function
# - Code cleanup
#
# * Sat Aug 07 2004 - v0.1
