IP tracking

I've been having repeated problems with people posting ads in my guestbook. The ads are for stuff like viagara etc... My website a family site, and this is a big nuisance!!! Is their a program or code that I can use to track IP addresses to my site? I can block them if I can find out their IP address, but I don't know hoe to find it.
Please help!!!
Thanks

You can do that but it depends on the application server (programming language) thats being used to figure how you would do it. for example PHP, Perl, cf, asp, blah. Then you also have to figure how your going to save those ip address. You can use mysql postgre, mssql odbc, access, blah. You could also write a script that would deny block posting on your guestbook from certain IP's, again depending on what language your using. Anyway , I recommend Coldfusion because its a markup language like html, so its easy to learn

CF is about the last language I'd recommend. If the site is currently hosted and they don't have CF you're out of luck and since most servers don't have CF the chances are slim. If you've got a dedicated server that you control then you could put CF on it, but it costs $$$, unlike so many other choices that are free. The touted advantage of CF (that it's easy to learn) doesn't make much sense to me - All web programming languages are easy to learn.

Since IPs change all the time the best way to make sure nothing "bad" gets through is to approve all the entries. I don't know what you're using for your guestbook, but some of the better ones have this option built in. If not, writing a guestbook is a pretty trivial programming task. If you're already profecient it shouldn't give you any trouble, if you're not it's a good beginner challenge.

I have to disagree. Coldfusion like I mentioned is a mark up language. Ill say it again coldfusion is a mark up language. Its a natural progression from hypertext markup language, also There are many coldfusion hosts some as low as 5 dollars a month or even lower in some cases. However I do agree a guest book is a good beginners challenge. If your interested in coldfusion, the best book imo is wiley and sons coldfusion bible. A free developers edition of Coldfusion can be obtained through macromedia if youd rather not pay for hosting while you learn.

You can probably setup your web server to block affending web site. For instance Apache web server uses:

There is usually a way to do it with out mucking with a programming language as the other two gentlemen are arguing about.

But unless one has a high degree of control over the server and server administration knowledge that solution is out of reach.

It would be interesting and helpful if posters would include more info about their setup. I'd be willing to wager that the average question asking poster here is working on their 1st or 2nd "real" website and it using a shared hosting account that's running on a *NIX based machine.

I would further guess that if the average question asking poster had any idea how to go about most of the suggestions they're given they wouldn't be asking in the first place.

Maybe this particular poster will enlighten us with his/her setup.

ok, this IS my first website. I have had it up for a year now. I own the whole domain, but don't know much about my server. I know that I CAN block IP addresses, but I don't know how to find their IP address. They do offer software to block them though. The site is www.noneofyourbusiness.ca (maybe it will help if you can see the site) I purchased it from webcentre.ca . I don't really know any other info thatn that.
