+ don't give a default gateway in the DHCP service, disable ip_forwarding in /etc/sysctl.conf and/or setup iptables to drop all packets to the WAN, coming from the student work stations (put them in a separate sub-net) > (btw, not giving the lab internet is a very very bad way of setting up > an instructional lab) Having been involved in training, I used to feel the same way until I realized that some of the students are more interested in surfing than learning; not doing the exercises etc. and then later claiming they do not follow the class. Blocking Internet access was the the solution. With the apt-cacher requirement, the OP is trying to balance the two needs. -- Arun Khan _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
