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 Intranet address port is the Intranet MSSQL address port, which is customized by the Internet address port. (2) After the ing is successful, access the Internet to connect to MSSQL using the mapped Internet address doma
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
Performance test of LAN switch interface in Flight Tower firewallUnited States flight Tower Fortinet Firewall, the default intranet interface type is hardware exchange, all intranet interfaces share a gateway, the intranet interface allows mutual access, here will be two notes A, B access to the 13, 14 ports to be tested. Notebook A's
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.
I also have two NICs, one is the Office intranet and the other is the Internet.Set the IP address to 192.168.1.111 and the gateway to 192.168.1.1.Nic connected to the Internet, IP: 192.168.0.111, and Gateway: 192.168.0.1In the command line, run the route print command to view the current default route table:The bottom row: Default Gateway: 1

The proxy server settings have many surprising relationships with the IE region.
The Local Intranet Zone is easy to use. It allows TCP/IP to allow servers on the other side of the earth to access the same server as the server on the lower floor .. on the other hand, the question "local" is left to the user or the network administrator to answer. it is easy to guess that when the machine is a local Intranet

First, explain the concept of "intranet" and "Extranet":
Intranet: That is to say the LAN, such as the school's local area network, the local area network each computer IP address in this local area network has the mutual opposite sex, is not repeatable. But the intranet IP in two LAN can have the same.
Extranet: That is, the Internet, LAN through a server or a r

This article focuses on the Intranet penetration elevation, which is not described for WEBSHELL.
Anyone who knows about intrusion penetration knows that after obtaining the webshell, the server must first find the vulnerability where the Elevation of Privilege is located.

What are Intranet, public network, NAT public network, and Intranet access methods of the Internet. Intranet access mode: the IP address obtained by the computer accessing the Internet is the reserved IP address on Inetnet. The reserved IP address can be in the following three forms: class A 10.0.0.0 8/GdIi4i Class B 172.16.0.0 -- 172.31.0.0 S {s si8} Class C 192
Company A accesses the Internet through ADSL, and the Intranet accesses the Internet through an ADSL Broadband Router sharing an ADSL cable.
With the development of Company A's business, the company needs to build A Web server for Internet access. The Web server mainly includes a company website, and is responsible for submitting daily orders and submitting business information of employees on business trips.

For example, the domain name is free of charge when registering a peanut shell, because it is in the internal network, so the intranet version is used, set the intranet host, after Port ING, save, the Internet access address is automatically generated.

One successful test of Sohu and sogou Intranet roaming0x01:
During the early tests on sohu network, a large number of sohu IP addresses were collected. For specific cases, refer to my previous cases. This is not the focus.

Perform in-depth mining based on the collected ip addresses and obtain the following ip addresses:
220.181.61.204. Actually, it corresponds to the domain name app.m. TV .sohu.com (which was also confirmed later)
