Afterall, there are millions of (windows) PCs behind NAT routers, doing OK - I suspect that these days, hackers get in by virtue of the trojan route - clicking on a link, opening an email, etc. rather than directly attacking home PCs.In these cases, yes, a firewall might help, but it's going to be a firewall doing packet inspection, payload monitoring, etc. that you really need...And if you're desktop is running Linux, what are you concerend about?Now... Myself and may many others host Linux servers directly connected tothe Internet - what firewall protects them? The answer in my case is; Their own. But really - if you're not running anything that's open, (that you don't intend to be open), what is there to protect against? You can nmap your own servers/PCs to see what's open, or use the netstat command inside them (which might not protect against a netstat trojan, however) Gordon
if we manage to raise enough funds to hire a room out properly such as the one at the torbay play centre can someone do a presentation on all this sort of stuff please
may need one before hand to explain networking and other concepts but i think there is a need for this among new and existing users who want to learn more. ok some people know it, but if presentation follows on from a then we can make sure that a covers everything that is needed to understand b properly
