Good firewall prog?

Trojans active on your PC can use practically any port. Here's one list of ports and known Trojans that use them:

Don't confuse this with ports that require closing, which are very few in number.

Don't actually do this, but if you were to do a fresh install of Windows and go to a port scanning site, you wouldn't see the ports you mention as "open". They would be "closed", meaning there is no service holding them open to inbound traffic. The ports you would see open would be the ones I mention and deal with in my article. You only have to close this small handful of ports in order to have all 64,000 + ports closed to inbound probes and requests for service.

A software firewall will block incoming on all ports not being used, and thus mask the situation. All ports will test as either blocked or "stealthed" at port scanning sites rather than either closed or open. This is due to the lack of a normal response from your IP address.

I hope this simple explanation helps. It is a very complex subject.

Note that files copied between computers on your LAN don't actually use the router.

(NetBios).

Probably not, unless you forgot to disable uPnP on the router.

I do have the free version of ZA on my W2K partition as well as the Linksys but since I never go on the internet from 'doze I have far fewer problems than most folk.

If it happens to be a laptop with a PCMCIA slot, you can get an adapter to provide ethernet connection. I had one from IBM on my old TP 385XD.

Are you on a dial up?

I'm surprised at that since I've had as many as four computers on mine moving files all over the place and not had a problem.

I use a VERY obscure password for the router.

You communicate with the Barricade via your browser and I have Javascript blocked except for selected sites, like my bank and CC accounts. I don't know if there's any safety there or not.

Probably the best safety is to browse with extreme caution, since that's the likely source of most of the crap.

I love to cook with wine.      Sometimes I even put it in the food.

Have done that in this thread and the link is at my web site.

It would run without the 'M' in 16K, IIRC. It ran fine in 48K with a single floppy. I soon had enough memory[*] to put a whole floppy in a RAMDISK.

[*] While the PC came with 48K, I had 320K within a month and 720K within six. I had a free source for 256K DRAMs. ;-)

Yes, but don't forget that the PC "cost so much" too. I don't believe many were actually sold with 16K, since memory was a hugely profitable item at the time. The systems were constrained, so one bought what was available.

Without the macro processor, IIRC.

One could get to 704K, but it took s some ingenuity. ;-) The AST sixpacks came out shortly after, with 256K DRAM. There were others as well.

It was before too (704K was the real limit before one ran into the CGA/MCA buffer). The memory configuration switch settings weren't officially documented above 256K, or some such, though.

Thanks for the suggestion. Yes, I had an older wireless router (no ADSL or cable modem) which gave no trouble.

I think I'm going to try another Belkin product.

I have two main criteria. It shouldn't crash and the settings should not be lost if power is removed. Of course I'd like it to contain a Gigabit switch and two WAN interfaces - but then beggars can't be choosers.

If you can sit at your machine and converse with the router, then in principle there's no reason why a program on your machine shouldn't be able to do likewise. And if you permit remote administration - someone could connect from outside to do the same.

It would probably be a good idea to change the router's admin password from its default value (admin I guess).

I protect myself by running on Linux - but that doesn't make me immune (as I have found out).

It really was that long ago, and I don't miss the 8" floppies one bit. Back then I did a good deal of dedicated microprocessor programming for industrial use, and all program development was done with 8" floppy based systems, I remember having the cat's meow setup with a triple-drive setup, imagine that, 3 floppy drives on one system, woot! Seems to me the 8" floppies were 256k, 512k and 1meg in capacity, does that sound warm?

Absolutely. Got the FDC and software from Flagstaff Engineering. Their first FDCs were made by modifying the IBM FDC, adding the logic "dead bug" style, and (i think) some port was used to switch between the standard 5.25" clock rate to the 8" clock rate. The sofware allowed one to read and write thousands of CP/M, Unix and IBM mainframe formats (both floppy sizes). Best of all was the high density 8" DOS format that was added, allowing over 1Mbyte of data!! It was great to be able to back up those expensive, huge 5Mbyte hard drives with only a few floppies.

By using Google, i have found some of those (serial port/s and included modem) - but they want over $700 for the beasties.

It is a mini-tower, and on dial-up.
