IP SNIFFER?

[BUBBA32]

Is there such a program as IP SNIFFER or ISP SNIFFER? It is supposed
to find the IP or ISP of someone who logs onto a web site?

Thanks.

If i wanted to find someone's IP address after they looked at my website,
I'd just read my web server logs.

Yes there are IP Sniffers out there but I wouldn't use them for the thing
you describe personally.

Hi

IP Sniffers are illegal and can cause all kinds of problems to your system - leave them alone.

What are you driveling about? Any tool can be dangerous for anyone not properly
trained. Sniffers are not illegal and how can they create problems to the system?

Unauthorised use of one is in fact illegal in this country. It appears from
his email address that Will and I are both from the UK. You'd have no
trouble prosecuting someone under the computer misuse act if they attached
one to your network without your permission.

and how can they
create problems to the system?

As it happens I've seen a buggy IP Sniffer upset a network card that had a
slight fault and slow down a network to a fair degree with a lot of
broadcast traffic.

So thats causing problems and illegal right there. What else did you need?

LOL! Sniffers are so old in name, that they are barely used anymore. There are still some sniffers that are not illegal, hell your personal firewall can sniff another's IP addy, and then provide some detail to the "whois" of that addy owner. So, is that illegal?

One type of proggie that has virtually no laws written for it, as the law typically uses them, are the various levels of "Honeypots" usage, which is perfectly allowed depending on various US/State laws which work under the "Federal Wiretap Act" and the "Electronic Communication Privacy Act" (Law enforcement officials use these a great deal).

NOTE:

Unless you are expert at using such security devices, don't think you can just find a nice "Honeypot" program and use it! They take a good learning curve, and can easily be used against you by another that sees it with a decent NetBus/backdoor proggie that understands the various levels of Honeypots.

Not so. I've got a perfectly modern program that describes itself as a
"sniffer" on a laptop I use at work. I'd admit it doesn't bear much
resemblance to what people first used "back in the day" but then a Dell
server running Windows 2003 doesn't have much in common with an IBM 3080
400J mainframe, but both have been used to run businesses and both have
given me a wage to pay my bills.

personal firewall can sniff another's IP addy, and then provide some

No. That's not sniffing. If I connect to your computer I present you with my
IP address. If you run Whois, it doesn't touch my computer but simply looks
up the owner of the netblock I claim to be from in a database.

Here we see a problem with the talk about what is legal and what isn't - a
point I was trying to make in my original reply, in fact. Will (I think) and
I are both from the UK. You are from the US I assume if you know about the
US federal and state laws. There isn't much reason why I should care about
your countries laws, nor you about mine, yet we all have to share this here
internet.

Unless you are expert at using such security devices, don't think you
can just find a nice "Honeypot" program and use it! They take a good
learning curve, and can easily be used against you by another that

Honeypots are quite interesting for professional security use, I'd agree. I
wouldn't suggest they were viable for most of the people who post here.

I find Ethereal to be an invaluable tool for network troubleshooting. In
fact, I wouldn't trust a IT pro to run my network if they didn't have a
decent network sniffer as part of his/her toolbox.
