Hi,
Is there anyone here who knows iptables?
On our new LTSP server, I wanted to employ our old script to lock the
classes from using the internet during lessons ;-) But now it fails with
an error.
The [antique == 2004] script reads as follows and is supplied with the
usernames from a list in ".inetlock.list":
#!/bin/sh
sudo /usr/sbin/iptables -A OUTPUT -d 127.0.0.0/24 -j ACCEPT
for i in `cat $HOME/.inetlock.list`
do
sudo /usr/sbin/iptables -A OUTPUT -d ! 192.168.10.0/24 -m owner
--uid-owner $i -j DROP
done
Executing stops in the loop and says Bad argument '192.168.10.0/24'. I
studied the current manpage, but cannot find anything wrong with this rule.
Thanks for any hints!
Rolf
