B-day cracking with proxies.

[Tom]

So I was reading (you need an account to see links) and I thought I'd clarify how to use proxies to circumvent this IP banning conondrum.

The birthday cracker can be found here: (you need an account to see links)

According to this post (I don't play NP so I can't vouch for accuracy) you become IP banned around 2 months of sending B-days:

Let me know if you find a way around the IP ban, it seems to last 20 minutes. I can send about 2 months of tries and then the ban happens. I can continue using a proxy, just not really viable to embed an always working proxy (considering they get refreshed and blocked).

The time it takes to send 2 months of requests is subjective to your personal connection speed, so time it and get a general figure.

Next get a proxy to use.

Some reputable proxy sources can be found here:

Use CoDeeN proxies (filter them via the HMA link) if possible, as they are the most reliable.

Afterward, follow these instructions to force Java to send HTTP requests through a Proxy:

Please log in to view spoilers.

To access the Java settings on Mac OS X, run the following command:

/Applications/Utilities/Java\ Preferences.app/Contents/MacOS/Java\ Preferences

On OS X Lion, it's under “Application” –> “Utilities”.

If you're running Linux I'm assuming you know what you're doing.

Now just repeat these steps with a separate proxy every time 2 months worth of B-days are sent until you find a match.

I'd like to add that the speed is variable to the chosen proxy, and if possible, it would be better to invest in a VPN that allows IP rotation for these types of things.
