Here's a little trick you can do to effectively disable your TCP/IP connection to the internet that I find works. If you go to DOS (Run Command.com) you can type a command called ROUTE. One of the parameters is PRINT. So do a ROUTE PRINT and look for an entry that has the Network Destination of 0.0.0.0. That will point to your default gateway (your router). Okay, write down the ip address at the end of that line under Gateway. To disable TCP/IP to the internet: ROUTE DELETE 0.0.0.0 To reenable TCP/IP to the internet: ROUTE ADD 0.0.0.0 MASK 0.0.0.0 <Gateway IP> You can even create a batch program with those commands and call them Disable TCP.BAT and Enable TCP.BAT if you want, stick them on your desktop and run them when appropriate. If you totally screw up your routing table (that is what you are modifying) don't worry about it, just reboot your computer and all will be back to normal. This will work under Win9x and WinNT and probably under Win2K (not tested there). Basically, what is happening here, is outside machines can STILL get to your computer, your computer just won't respond. It doesn't know how to talk to them back. No route. Any way they try to connect to your machine they'll get no response, your machine is not visible to/from the internet without a gateway.

With me still on AOL, the likelihood of some hacker getting to my home PC that way is rather remote, but still possible through one of the scams ... there is a non-stop stream of "click on this" which is coming from criminals to AOL members & most of them rather illiterate criminals. The only clever ones are the first to come up with some new scam - the last "good" one I saw was claiming to be from AOL billing telling me that there had been a problem with my credit card account when the monthly billing was done & I need to click on here to go to AOL billing to straighten it out, which was really a web page that LOOKED like AOL billing as part of an elaborate scheme to steal credit card numbers. I managed to figure that out instead of falling for it. Once one criminal had figured this out, there were a thousand copycats. But when we are connected to the internet all the time via some high speed line that is purely for that purpose, which is what is coming to me, then we are at risk of joining the conspiracy of DOS & other things, where criminals recruit unknowing personal PCs to participate in mass attacks on their ultimate targets. There was also the bit about Microsoft being hacked because an employee had a home computer with no firewall - the hacker got into the employee home PC then from there Microsoft security had a pervasive flaw in making it too easy for unauthorized persons using employee machines to get into Microsoft corporate systems. And of course these people are forever coming up with new ways to cause mischef. Home PC Security with DSL/NIC: I need to find some way of turning off the high speed internet connection when I am using my PC for something other than internet connection & I not yet know if that is doable for the system that I will be getting; I will need to have a firewall, when in fact I did not need one for dial up AOL; there are various tips I need to understand ... what does this do for me & what are the pros & cons of unplug physical connection turn off file and print sharing options MacWheel99@aol.com (Alister Wm Macintyre) (Al Mac) > From: email@example.com > > I have a question.
