Provided you disconnect regularly Hugh, this is the key to this theory. I, like most every other dialup user I know, am connected for 1-6 hours continuously and I personally know 2 seniors who have dedicated dialup connections. They connect when they boot up in the morning and disconnection at shutdown in the evening, or power outage (whichever may come first ;>) Utilizing Snort Intrusion Detection Software or IDS I can pick up regular attempts continuously on XP and Linux. Dial up connections present different scenarios than broadband connections and software firewalls are required more often and as these are built-in in both XP and Linux (as you likely know). Linux has the advantage in that its software firewall/NAT can filter outbound traffic as well. Because even a fully patched system can get a trojan working perfectly well, human error can work wonders :) Peter Kaulback Hugh Vandervoort wrote: > The experts all agree that a firewall is unnecessary with dial up.
