Internet restriction / parental control
Hi, I refer to this forum: http://forum.x-wrt.org/index.php/topic,403.0.html
I would like to adapt this Internet restriction / parental control to my WL-500gP.
They were having such scripts:
control-internet.sh
Code:
#!/bin/sh
###########################################################
# Control access from the LAN to the Internet (WAN)
#
# This script must be adapted to your configuration to fit your needs
# It can be used in a cron job or by the Webif^2 page Misc/Restrictions
#
# Usage: control-internet.sh [status|open|close|explain]
# status Returns 0 if traffic is allowed to the Internet
# open Open traffic to the Internet
# close Block traffic to the Internet
# explain Print info on stations blocked
#
# Author: Pierre Métras <p.metras@videotron.ca>

case "$1" in
"status")
status=$(/usr/sbin/iptables -nvL | grep "DROP" | grep "192.168.1.3")
if [ "$status" = "" ]; then
exit 0
else
exit 1
fi
;;
"explain")
# Print information on blocked workstations
echo "192.168.1.3 (archibald) 192.168.1.4 (esmeralda)"
exit 0
;;
"open")
# Drop all rules blocking Internet access
/usr/sbin/iptables -D forwarding_rule -s 192.168.1.3 -j DROP 2> /dev/null
/usr/sbin/iptables -D forwarding_rule -d 192.168.1.3 -j DROP 2> /dev/null
/usr/sbin/iptables -D forwarding_rule -s 192.168.1.4 -j DROP 2> /dev/null
/usr/sbin/iptables -D forwarding_rule -d 192.168.1.4 -j DROP 2> /dev/null
exit 0
;;
"close")
# Add iptables rules to block Internet traffic
# If cutter package installed, then cut active connections
# cutter: http://www.lowth.com/cutter/
if [ -x /usr/sbin/cutter ]; then
/usr/sbin/cutter 192.168.1.3 2> /dev/null
/usr/sbin/cutter 192.168.1.4 2> /dev/null
fi
/usr/sbin/iptables -I forwarding_rule -s 192.168.1.3 -j DROP 2> /dev/null
/usr/sbin/iptables -I forwarding_rule -d 192.168.1.3 -j DROP 2> /dev/null
/usr/sbin/iptables -I forwarding_rule -s 192.168.1.4 -j DROP 2> /dev/null
/usr/sbin/iptables -I forwarding_rule -d 192.168.1.4 -j DROP 2> /dev/null
exit 0

echo "Usage: $0 [status|open|close]"
echo " status Status of bridge to the Internet (0 = open)"
echo " open Open traffic to the Internet"
echo " close Block traffic to the Internet"
echo " explain Print information on blocked hosts"
;;
esac
and also it would be nice to add an extra html internet control page:
misc-restrictions.sh
Code:
#!/usr/bin/webif-page

I did some adjustments to the above files and it looks like cron works. I can not ping the archibald or esmeralda but I can ping my ASUS.
The problem here is the cutter. Now my question would be how to install it?
Any help appreciated.
Thanks.
