Randomizing IP address (10, permasaged)

1 Name: #!/usr/bin/anonymous : 2008-05-16 23:55 ID:nP8uvPZV

Lately, I've become enamored with the idea of IP spoofing. There are several ways of spoofing IPs when it comes to DoS attacks on a TCP/IP or UDP level, but I'm not looking for something like that. Just a simple way to get a page while sending a random IP address, on the HTTP level. (And no, I do not mean through proxies. I mean through a randomly-assigned IP address.)

I've been trying to do this with PHP using the $_SERVER['REMOTE_ADDR'] variable, but, as of yet, I have had no luck. Is anybody familiar with this idea or how I would go about properly programming it?

Well, never mind all that, >>1. This has nothing to do with this thread, but would you just listen to me for a little bit? See, I went to the local Yoshinoya today. Right. Yoshinoya. And the damn place was packed so full of people, I couldn't even find a seat. So I looked around a bit, and I found a sign that said "150 yen off". What the hell is wrong with you people? Are you idiots or something? Any other day you wouldn't even think of going to Yoshinoya, but if it's 150 yen off, you all flock in here? It's just 150 fucking yen! 150 yen! And you're brining the kids too. Look at that, a family of four going to Yoshinoya. Con-fucking-gratulations. And now the guy's going, "All right! Daddy's going to order the extra-large!" Shit, I can't watch any more of this.

Yoshinoya should be fucking brutal. Two guys sit facing each other across a U-shaped table, and you never quite know if they'll suddenly just start a fight right there. It's stab-or-be-stabbed, and that's what so damn great about the place. Women and kids should stay the fuck away.

Well, I finally found a seat, but then the guy next to me goes, "I'll have an large bowl with extra gravy!". So now I'm pissed off again. Who the fuck orders extra gravy these days? Why are you looking so goddamn proud when you say that? I was gonna ask you, are you really going to fucking eat all that gravy? I wanted to fucking interrogate you. For about a fucking hour. You know what? I think you just wanted to say "extra gravy".

Now, take it from the Yoshinoya veteran. The latest thing among the Yoshinoya pros is this: Extra green onions. That's the ticket. A large bowl with extra onions, and egg. This is what someone who knows his shit orders. They put in more onions, and less meat. A large bowl with the raw egg, that's really fucking awesome. Now, you should know, if you keep ordering this, there's a risk employees might write you up. This really is a double-edged sword. I really can't recommend this for amateurs.

And you, >>1, well, you should really just stick to today's special.

I'm sorry, could you repeat that?

Read about TCP/IP. What you are trying to do is not possible.

We are >>5's courtiers.
We are sorry that our lord has created such a stupid post.
After the last war we had completely lost, our lord got mental illness.
Everyday, he kidnaps girls from the village.
Every night he gets drunk and tries to chop courtiers with his katana.
Now the lady of the house is ill in bed.
The people in our country are suffering badly from famine.
The neighboring Daimyos is taking advantage of this situation,
they try to pass across the border and take over our land.
Quite a few of our fellow courtiers have intention to rise in rebellion.
We are now in dire straits. Our clan would be destroyed.
But, don't worry. We arranged that our Lord become a Buddhist priest.
On his way to the temple, our skilled assassin will take his life.
That is arranged perfectly. After that we will hail Master Monaminokami,
the nephew of our lord, as our new lord.
We, all courtiers, would do our best to serve this new lord with faith.
We apologize for any inconvenience our lord may have caused you.
Please wait for a while. Please forgive the evil deeds done by our lord.

You do not know what you are talking about.

Spoofing ip's with a language that explicitly works at layer 7... No...

Spoofing ip's "on the UDP level"... No.

It seems that you missed the classes on the OSI model when you were taking COMPUTER SCIENCE 3 because IP is completely different than UDP, not to mention that the IP header is added to a packet WAY FUCKING BEFORE the tcp or udp headers are added.

Not to mention that ARP WOULD RENDER THIS COMPLETELY USELESS.

Your packet would not be routed because when you arp out with
who has <default gateway address here>

and after it arps out with who has <your ip address>
and you respond with the wrong mac you wont get shit. Because you are not answering with that mac.

Okay then, allow me to rephrase my question.

There exists programs such as synner.pl or Xxpoof where one can send spoofed source packets to a target IP address. However, this is only limited to IP addresses. Is there any such way to do the same thing, but to a certain URL, rather than IP?

Say, for example, that example1.com and example2.com share the same IP address, but you only want to spoof an IP packet for example1.com, not example2.com. Would this be at all feasible?

Now you're not talking about spoofing the network -- you're talking about spoofing the application. In this case, it sounds like you want to send incorrect host headers to a web server that is configured to read the host header to determine which virtual host to pretend to be.

Yes, you can do this. But it isn't really going to get you anywhere. Google webscarab.
