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
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.

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

Many programs in the local area network can be applicable, but between the external network and intranet and between intranet and intranet is not feasible. The problem is NAT, this article will introduce the next 5 Nat penetration method, solve the internal and external network exchange. 1. Fully conical (full Cone) NAT

The author of the school through ADSL set up routes to share the Internet. The extranet gateway and DNS are 10.0.0.138, the external network port IP address is 10.0 0.1, and the subnet mask is 255.255.255.0. Self-built sites are placed on the server, on the server has been
IIS is installed and set up, and the "Default Web site" IP address points to 10.0.0.1.
In the default state, you can access the extranet, but you cannot access the intranet. If yo
1. Lan Layer
Many preventive measures can be taken on the LAN layer. For example, although it is almost impossible to completely eliminate the counterfeiting of IP groups, the network management can build a filter. If the data carries the source address of the Intranet, it can effectively reduce the internal counterfeit IP attacks by limiting the data input traffic. Filters can also restrict external IP group streams to prevent DoS attacks from fake I
PrefaceWe know that during Intranet penetration, ARP spoofing, DNS spoofing, and other methods often have a great impact. In addition, due to the old technology, there are many defense software, in addition, many network devices gradually have the ARP spoofing defense function, which makes it difficult for our Intranet penetration.Recently, I used NetBios Spoofin
IptablesVery powerful. Let's take a look at one of the examples.
My network is like this! One FC3 instance and three win2000 instances form a LAN! All four machines are connected to a m vswitch. On FC3, two NICs eth0 are connected to the Internet, and adsl eth1 are connected to the vswitch. FC3 is used for nat and three win2000 instances are connected to the Internet! Because the bandwidth of ADSL is inherently slow, it would be even slower if someone uses BT in the

similar to packet filtering, and perhaps many friends had the impression that when the target network was defined, it did not recognize the network as 218.4.0.0/255.255.0.0, saying that the subnet mask was invalid, You have to manually configure the 256 target networks of 218.4.0.0/24, 218.4.1.0/24, 218.4.3.0/24 、、、 218.4.255.0/24, Because of the IP address of Class C, it only 255.255.255.0 such subnet mask, and there is like the IP address audit in IIS also has such a situation, Khan ~ ~ ~

What is port ing:
Port ing (NAT or napt) refers not to a port in the physical sense, but to a port in the TCP/IP protocol. It is a logical port. Port ing: if a computer on the Intranet needs to access the Internet, port ing is required. Port ing is divided into dynamic and static. dynamic port ing: if a computer in the Intranet needs to access xinlang, it will send packets to the NAT gateway, including the
Today, we will talk about how to use port ing without using the gateway to open the Intranet.
I. Prerequisites
A public IP address is required. Assume that we have a public IP Address: 210.210.21.21.
Ii. Tools used
1.lcx.exe
2. vdic
Iii. Methods
Method 1: Use lcx.exe for ing.
(1)we will upload lcx.exe to the public IP address, and execute lcx-listen Port 1 Port 2 in the DOS environment on the public IP Address
See lcx-listen 3030 for details.
