#                                   code (C) 1999 by rofus                                #

# WHAT IS:                                                                                #
# This simple ip-{up-down} script update at every connection (when the ppp daemon starts  #
# and when is closed) your etc/hosts file with your actual REAL ip and hostname (useful in#
# some cases).                                                                            #
# USAGE:                                                                                  #
# For usage read carefully the ip-up file!                                                #
