If there are any kind of machines on the INTERNAL network that can be infected by some type of worm/virus then their could be a possible problem in the future. Especially if there are some computers connected to both networks. (lets take support or billing for example)
But in any case, I plan on combining TMDA with some sort of filtering. Very conservative filtering for whitelisted messages, and strict filtering to sort unwhitelisted messages into not-whitelisted-but-probably-not-spam and almost-definitely-spam folders, both of which could still be overridden by a response to the challenge.
Since the "Reply-To:" header is set to the TMDA dated address a spammer can simply get into your white list with a simple auto-responder. If the spammer has access to alot of disposible e-mails with properly formatted auto-responders alot of spam is still going to get through.
Upon closer inspection of the program, the TMDA does infact include the dated address in the "Reply-To:" header. Wheni first looked at it i only noticed the "From:" header of the origial address.
Now if every one used this method its still not going to stop the SPAM. Sure, in this case the SPAM will be now confirmed to an Address where the investigation can start from and posible removal of the account. But i think the SPAM will contiue without too much trouble.
I still think filtering the better method right now.
Another common worry is that two TMDA installations will create a mail loop as they send confirmation requests back and forth.
This will not happen, as TMDA is configured to not respond if the message contains identifying characteristics of a mailing list message, bounce message, or auto-response such as the vacation program (or another TMDA message!). Even if this fails, the mail-loop will be stopped by TMDA's auto-response rate-limiting feature that puts a ceiling on the number of messages it sends to a given address in a day.
Lets expand my example a little bit. If either TMDA does not recongize each other a loop will be formed between them, BUT after the number of messages hits the ceiling then it will stop.
Great, now the mail stops and doesn't get to be delivered.
What would happen if two peole are using ISP's that have TMDA installed, and neither have been confirmed with each other?
Joe e-mails Fred. Fred's TMDA sends a confirmation e-mail to Joe. And Joe's TMDA sends a confirmation e-mail to the confirmation e-mail, then the cycle continues.
Imagine getting mugged and having your finger or thumb chopped off. I'd rather have some type of removable object that needs secondary comfirmation. I know the existing debit card fits into this, but it has to be free to use to be widely accepted. I hate to pay to spend my money.
How about a disc and caddy system that is just like a mini disc? I think people would accept it, i know i would. Myself I'm tired and annoyed with all the scratched and damaged discs i have.
Good luck with pulling nylon cord along with your cable runs, as you will soon find out that it will tangle and wrap around the cable that is already there and will be a BITCH to pull through unless you take everything out and pull it all again fresh.
That games ruled... We played that one for hours in school. I can still remember a fellow in school who ripped out the text font from Ultima and attached it to Tiapan, then altered the boat graphics into jets and planes. We used names from everyone in the Computer club and locations we thought of and basically played it until out eyes dried up.
The cheap ones are not the fastest nor are they the biggest nor are they the most realiable. the most reliable ones are not the fastest nor are they the cheapest.
Most users who setup small cheap IDE Raid systems only tackle the basics of the system. In order for it to be reliable you will need 99.999 uptime. For alot of users once the data is partially secure they call it finished. How many of these users factor in Hotswap Power, Hotplug controllers and hotswap drives? Most likely very few.
You can throw all this into your system if you have 3 5-1/4 bays and a PCI slot free. Or invest in an extra computer and a couple gigabit network cards to make it external.
If you need more space than than then get a 7500-8 or 7500-12 and add more drives.
Get yourself a CDROM that properly supports Digital Audio Extraction and the process will speed up alot. If you have the free space available, then the fastest way is to Extract the audio with no compression first (if your cdrom has good digital audio extraction), then convert it to vorbis or MP3 after the fact.

Just use what ever is available.
Small ethernet hubs/switches are cheap.

I don't like the looks of this.

If you assume that the new laser hardware can be squezed into the same amount of space, then your practical limit is . 5 disc.
more coins or smart cards?
What happens if one of the Computers is off in the middle of the chain?

Oh, the memories
But all i made was a general comment. Why did you read so far into it?
But isn't the majority of the planet using the Metric system?
Oh my lord, what did i say to deserve this?
