# Hotfix script for TYPO3 to mask IP address for data privacy protection reasons.
# The IP address xxx.xxx.xxx.xxx will be masked with xxx.xxx.xxx.0
#
# Work with Typo3 4.2.x and 4.3.x
#
# This script will search for affected files within MYPATH (can be changed
# below) and fixes every file automatically, keeping a backup copy with
# suffix ".<timestamp>" in the same directory. Permissions and ownership
# of the files will be preserved.

#
# Usage:
# 1) Make this script executable - maybe you like rename it to .sh
# 2) Run this script
#
# chmod a+x ./typo3_ipmask.sh
# ./typo3_ipmask.sh
#
# How to check if the fix was successful:
# Search the whole system for files named "class.tslib_fe.php" that
# contain the string "// Log part 2: Fake the remote logname"

# Start path: Search for affected files within this directory. Leave
# default if unsure.
MYPATH=/

# Do not change these values!
