Proxy Bypass

So shit.  I was programming something for someone else (C#) that uses proxies to vote for something multiple times.  When I finish the program, turns out the server checks for proxies...  Any way around that?

Thanks,

Does it have a list of proxy servers or something? If so, it's just a matter of finding one that it doesn't know (if you can).

Or, you could try and construct your packets from scratch so that you can spoof the IP address. I dunno if .Net will let you do that, but you could code that part in C and use DllImport to call it. I'm pretty sure you can create raw packets in C.

Also, you could try Tor, but you'd have to restart Tor every time you wanted a new connection because otherwise Tor would just use the same relay & exit node.

Yea you can code your own HTTP in C# (it's just a TCP socket with formatted text).  Thanks anyway

I think Tor would give me the same problem, but thanks for the response

I think the server has some way of knowing that you're using a proxy.  Anybody know how that works?

some way of knowing [...] how that works?

Either the server has a list of known proxy servers
Obstacle likely defeated by spoofing IP addresses, mentioned above.
OR checks the user agent
Spoof user agent -- simple.
OR checks the referrer
Not that hard either.
OR checks a cookie.
These aren't really that hard to work around.

Thank you, come again.

This, also make sure you have a cookie jar setup to act like a fake client

Use P/Invoke since you're using C# and do as >>2 said. It doesn't seem too difficult.

Kneading is an activity common to all domestic cats whereby, when in a state of ease, they alternately push out and pull in their front paws, often alternating between right and left limbs. Some cats actually appear to "nurse" or suck on clothing during kneading.

History
Multiple theories exist that explain why cats knead. Kneading may have an origin going back to cats' wild ancestors who had to tread down grass or foliage to make a temporary nest in which to rest. Alternatively, the behavior may be a remnant of a newborn's kneading of the mother's teat to stimulate milk secretion. Since most of the preferred "domestic traits" are neotenous or juvenile traits that persist in the adult, kneading may be a relic juvenile behavior that is not lost in modern adult domestic cats.
Kneading is often a precursor to sleeping.
Many cats purr while kneading. They also purr mostly when newborn, when feeding, or when trying to feed on their mother's teat. The common association between the two behaviors may corroborate the evidence in favor of the origin of kneading as a remnant instinct. Some experts consider kneading to "stimulate" the cat and make it feel good, in the same manner as a human stretching.

Action
The cat exerts firm downwards pressure with its paw, opening its toes to expose its claws, then closes its claws as it lifts its paw. The process takes place with alternate paws at intervals of one to two seconds. They may do this while sitting on their owner's lap, which may prove painful if the cat is large or strong or has sharp claws (as the claws tend to dig into one's lap). Though cats sit happily on a hard surface, they only knead a soft or pliant surface, although some cats reflexively "march" on hard surfaces instead of kneading them.

interesting spam

All of those are hard to work around.

1. IP Spoofing wont get you anywhere unless you're using UDP: "this technique is mainly used when the attacker does not care about the response or the attacker has some way of guessing the response."

2. User-agent spoofing wont do anything because there's no reason to ban someone because of their user-agent...  Millions of people use the same user agent.

3. That's probably it.  Is there any way to spoof the referrer?

4. Cookies could be the problem, but I have no idea how I'd work around that.

This isn't the site that I'm targeting in my program:
http://bitcrate.net/
But this has the kind of proxy blocking that I'm talking about.
Any help is appreciated, thanks.

You could try setting X-Forwarded-For and Via headers beforehand to a local (RFC1918) address, so it looks like you're using a work proxy.

Wouldn't the proxy just overwrite them?

>>13
Probably. Personally I would use SOCKS proxies for this instead.
