Re: No NetBios share + No Open Port = Safe Win98?

This depends a bit on your router/modem. You should hit up an external firewall testing page to see if 139 is really reachable from the Internet. If it is not, this is good and your router/modem is doing NAT like most modern ones should be. Sites: http://www.hackerwatch.org/probe/ or http://www.auditmypc.com/

If 139 is reachable from those sites, yes, there are still ways to get into your computer with just port 139 open. Those sites should give you more info, but suffice to say you want port 139 hidden from the world.

And like you seem to already know, a system, ultimately, is only as safe as the user using it. Even with firefox and diligence, you can still let in something bad via a mis-click on an email attachment or web page. However, this is not necessarily something specific to Win98.


"Theoretically, I've not enabled port forwarding in my router/modem, and so external computer trying to ping or connect to my computer should not succeed, and if there's no port listening at all (except for port 139), no other computer should be able to infilitrate right?

Yet, I can't say anything is foolproof. So just like to seek your expert opinion. What are the other areas I should continue to look at to further protect my system? Is it still possible to be attacked through a listening port 139 with file sharing disabled?"
