, The dotted line below is the Internet, which provides Web Services, DB services, DNS services, exchange services, and so on; The above is the Intranet, which provides services similar to the Internet. This article focuses on the mail system under this structure.

The first description of our configuration file, are similar format, if the intranet is 192.168.0.3, the extranet is 123.123.123.123, the configuration file is as follows:
$db [' salver '] [' hostname '] = ' 192.168.0.3:3306 ';$db [' salver '] [' hostname '] = ' 123.123.123.123:3306 ';

How to use "mathematical modeling-graph theory model" for automated intranet penetration testing
Privilege escalation in the Active Directory domain is an important part of the struggle between most intruders and the Intranet administrator. Although obtaining the permissions of the domain or enterprise intranet administrator is not the ultimate goal of evaluation
Using dnsmasq to build a small Intranet DNS dnsmasq is a very small dns server that can solve small-scale dns query problems, such as the Intranet of the IDC. The general idea of www.2cto.com is as follows: Configure dnsmasq as the DNS Cache Server and add local Intranet resolution to the/etc/hosts file, when querying an intr

The Enterprise Network Security Administrator pays great attention to the harm to the Internet. Whether it is to deploy a security gateway or other protection products, the ultimate goal is to prevent the enterprise from being compromised by network security. However, administrators should pay attention to Enterprise Intranet security protection while enhancing Internet protection. This article analyzes six internal network security threats through so
Question 1: Cross-origin penetration
In an intranet, the domain administrator permission of Domain a (a. AB .abc.com) has been obtained, and the entire domain has been controlled. Net view/domain: B shows that many machines exist in B domain (B. AB .abc.com). machines in the domain can be pinged to machines in the B domain and want to penetrate machines in the B domain across domains, obtain the domain administrator permission of Domain B.

After a lot of chickens have been put on the horse, the black friends may be thinking about how to use the loot in their hands. Some people like to spy on the privacy of others, some may use the Trojan horse keylogger to steal someone's QQ password, some people may want to steal someone's broadband Internet access account charge Q currency. But have you ever thought that these chickens in the intranet into a SOCKS5 server? In this way, we can use thes

The first step is to ensure that your intranet machine can smoothly connect to the Internet through the so-called proxy server. Here we will not talk much about it.
Let's look at this picture. As for how the proxy server with a public IP address (or the proxy gateway) connects to the Internet (also in the question mark), this is an ISP problem for individual users, I won't talk about it here.
This server has dual-nic, one set IP address is 61.134.36.5
Use Cases:
Network problems when using both wired and wireless Internet access in a notebook:
1. My environment is Intranet/Internet isolation.
2. Wired connection is an Intranet (LAN ).
3. Connect a wireless router that can access the Internet (generally Internet. 802.1.1
Problems:
If my local network connection and wireless network connection are enabled at the same time, I cannot access the Interne
The following describes how to perform the operation. Take my computer as an example to give a demonstration.

Relatively speaking, there is little information on the Internet, and few people write some detailed information about the Intranet penetration for the reference of their peers. Today, I am only going to give a general introduction to some Intranet knowledge.
First, under what circumstances will we meet the Intranet? If your goal is only limited to a small web, y
Enterprise Intranet security product selection Source: Network Author: Network Release Date: In recent years, security issues have become increasingly prominent in the internal network (terminal), and security events have frequently occurred.

Intranet security management products must be intercepted with ARP Spoofing with caution. With the continuous popularity of Intranet security management products in the market, there are many product patterns with various ideas, but the trend of product homogeneity is obvious, in particular, for terminals to block illegal access to the Intranet, the method is gen
