In any case, if you have a small network, along with your DHCP, you may want to set reservations along with MACs so that at any time you can keep track of the machines. Not sure why your broadcast address is not showing the machine, but a more certain method is to use something like nmap: nmap -sP 192.168.0.0/24 Would yeild better results.

Using iptables of a proxy would be a better way. But if its only this one machine, then just remove its default gateway and it will not be able to access anything outside your network. However, it will access all services on your network.

Probably multiple way's of doing this, here's some off the cuff: 1. Provide it with an IP tied up with it's MAC (or a static IP) and then create a iptables (firewall) rule to drop all packets from that IP. 2. Use squid and squidguard to allow/disallow internet access.

[ilugd] Disabling Access to Windows OS computer on Ubuntu (linux) Network
Hi We have a simple network that is served by a Ubuntu 5.04 based machine. This machine basically acts as a DHCP server. We have one machine that is a Win 98 (or any other win system - it is connected to the network. I wanted to know if there was a way of disabling network access to this machine. ??? or simply preventing access to some served services !! (right term) like internet. will appreciate pointers and advice thanks ram ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
