Site Blocking
 
Hello,

Maby somebody can help me with the following problem;

I am father of two boys (seven and nine years old) and I have an ADSL connection to the internet for about two months. ADSL is working fine and since a month I even manage to run slackware linux for a NAT network.

Since a couple of weeks im aware of my suns both watching porno on the internet. This is something we don't want them to do so I tried to put the names of the sexsites (found in their history) in hosts.deny and I tried various things with iptables (which shares the internet towards the other computers) but nothing worked out.

Does anybody know a solution for us?

Thanks in advance !

Want to block sites from internet adress ? :

create a file with all IP adress you want to block, you could get them from domain name with ping command.

and a script like this :
Code:
# parameteter to change
BLOCK_FILE=/path/to/your_ip_to_block.txt

#path to iptables
IPTABLES=/usr/sbin/iptables

for IP in `cat $BLOCK_FILE`; do
    $IPTABLES -A INPUT -i eth0 -s $IP -j DROP
done
Naturally it is just an example how the thing could be done, it is not a complete iptables script as it does not deal with flushing rules, load modules etc.. It is intended to include in a firewall script

couldn't you also put the domain names in your hosts file to redirect the browsing to localhost?

Not a bad idea kodon ;) I know some friend did joke with that file, redirecting official sites like google to porn, the user wondered what did happen.

Site Blocking
 
I'm a parent too and am using SquidGuard to block undesirable sites for my kids. I haven't installed it on Slack and don't know if it will work. I'm using the 'SME Server' distro as a proxy server. The advantage of Squidguard is the 'blacklist' gets updated on a daily basis and I don't have to worry about keeping track of where the kids are going. Another is that I can use the Squidguard log files to see where they are trying to go, them clearing the history files on their machines doesn't clear it from my logfiles.

wait a minute

just realized you said SEVEN and NINE year old boys!?!?!

should have no interest in girls whatsoever...
