Again the general method is: ipchains -A input -p tcp -d your_ip_address:port -j DENY This will drop the packet as if it never occured. You can change the last part to REJECT in which case an icmp message is sent back to the originating host. But if you DENY the packet a port scanner won't see your machine. Don't rely on this to say you won't be attacked. It just lowers your profile. By the way, while ATT at Home is less secure then some ISPs, the internet in general is a hostile world. If you really want to secure against it cut the connection. Next would be to find an ISP that will place you behind their firewall. ======= Kirk Wood Cpt.Kirk@1tree.net
