I am working on a paper, but I have a little problem.
I think I am a little addicted to web surfing so I don't
get enough written on my paper.

So is it possible to block web traffic to my account at
some time interval ?

I maybe have to write a cron script.
But what program can I use to block the web traffic
of a single user?

I am running some servers on the same machine so just
polling the plug don't work.

as long as you are not trying to run a web server on your work station you can just block all port 80 traffic with iptables.

If you are addicted enough, you will kill the script when it takes effect

The best way is to prevent yourself.

well, I am runing a web server.

And I am not that addicted, but if I get an email
with a link in it. I sometime click it without thinking. An then suddently 5 hours has past.

If I can make it so that I can only use the web after 21.00. It would be fine.

I have made it now.

I compilet iptables into my kernel and put
these lines into my crontab

Code: Select all

0 7 * * * iptables -I OUTPUT 1 -p tcp --dport 80 -m owner --uid-owner shs -j DROP
0 21 * * * iptables -D OUTPUT 1

My user is 'shs', so this should work as intended, right ?
