Bayesian theorem
Bayesian theorem, in the era of machine learning flying, can simply be a simple machine learning model.
Theorem itself at a glance: P (a| B) = P (b| A) * p (a) (B)
In the case of B, the probability of a appearing is equal to the probability that both A and B appear, divided by B.
In other words, the relationship between the posterior probability and the prior probability.
As an example
We assume that the present complete collection is a primary school first grade students, a ref

1. Limit:
Can not visit the site, online games (such as the public) can not play, such restrictions are generally limited to access to the site's IP address.
2, Breakthrough:
This kind of restriction is easy to break through, with ordinary HTTP proxy can, or socks agent is also possible. Now the Internet to find HTTP proxy is very easy to catch a lot. You can easily access the destination Web site by adding an HTTP proxy to ie
number of times that a pattern match is replaced, and the count must be a non-negative integer. The default value of 0 means that all matches are replaced.
Here's a simple example of using the sub () method. It replaces the color name with the word "colour".

Wingate as an example, simply said. (Too tired)
Wingate is a very extensive application of a WINDOWS95/NT agent firewall software, internal users can be installed through a Wingate host to access the external network, but it also has several security vulnerabilities.
Hackers often exploit these vulnerabilities to gain access to Wingate Web, socks, and telnet, posing as a Wingate host to attack the next attack target. Therefore, this attack is very

Here's how to break the limit and need to be explained by the limitations:

Install it in the source file. You can directly install it and modify it later:
Tell tsocks what your socks proxy looks like (including IP addresses and ports ). This is done by modifying the tsocks configuration file. Generally, the configuration file is in/usr/local/etc/tsocks. conf. If this file is not used, tsocks is used. conf. for sample,

proxy! However, this proxy will strip some of your information (like the stealth mode of the firewall), so that the server side cannot detect your operating system version and browser version.
Transparent proxy (five-level anonymous proxy): This proxy will adapt your request fields (Message) and send your real IP address. Therefore, if you use this proxy to access the Internet, you cannot hide your IP address.

There may be many restrictions on LAN Internet users, such as websites, games, MSN, and port restrictions, which are usually restricted by software on the proxy server, for example, the most talked ISA Server 2004, or the hardware firewall is used for filtering. The following describes how to break through the restrictions:
1. Some websites cannot be accessed, and online games (such as the Internet) cannot be played. These restrictions generally restrict the IP addresses to be accessed.
