How to share ADSL Internet access between the operating system of the host machine and the virtual machine through a bridge network

Operating System: Windows XP SP2, single Nic, ADSL Dynamic IP, bandwidth 1 m.

DHCP (Dynamic Host Configuration Protocol) is a LAN protocol that uses UDP to work with two main purposes: assigning an IP address to an internal network or network service provider automatically, For users or internal network administrators as a means of central management of all computers, in RFC 2131 is described in
When assigning a value to the IP address structure, the function htonl,htons,inet_addr is often used , and the function corresponding to the sockaddr_in is ntohl,ntohs,inet_ntoa.
Looking at the parsing of these functions, it is found that these functions are actually related to the conversion between the host byte order and the network byte order .
What is the network
In fact, the network of such related articles a lot, I just want to combine their actual situation, my experience to write down to those who need it. Host: Windows XP virtual machine: Ubuntu 10.10 virtualbox:4.0.2
After the virtual machine is installed, by default, it is through the network connection of NAT, in which case, the virtual machine can go to the inte
Abstract: implements network communication between host machines and virtual machines

Second, host Order network Order
Different CPUs have different byte-order types These are the order in which integers are stored in memory. This is called the host order, the most c
Zhou has not installed a Linux Virtual Machine for fun. The final effect is as follows,
1) The host is win7
2) install a Linux system (Ubuntu selected) and WINXP on the guest Machine
3) directories can be shared between hosts and guest machines;
4) Intercommunication between the host and the guest. The Guest machine can access the Internet (you need to reset the settings before restarting)
5) Try to reinsta

Network Cell number host number
The first example: known ip:192.169.20.50 subnet mask: 255.255.255.224 to seek network cell number host number.
First, the subnet mask 255.255.255.224 is converted to bits
255.255.255.224:11111111.11111111.11111111.11100000
You can see that the left side of this mask is the same as the
15.2.10 host byte order and network byte order when you run a new version of the server and client on an Intel processor-based Linux machine, you canView network connection Status with the netstat command. It shows that the client/server connection is waiting to close. The connection will close after a period of time, as follows:You can see the port number of the
What is a byte order? Refers to the order in which integers are saved in memory. There are two kinds of byte order: A.little Endinan Low store in memory, high address in memory, B.big endian high store in memory low address, low store in memory;A simple example: DWORD dwcount = 0x01020304; Such a double-byte variable is distributed in memory as follows 0013ff70 04 03 02 01 (Note: The results of the experiment XPSP3 VC6.0, indicating that my machine is little Endinan order) And if the big endian

3. Host-only mode (host mode only)
Host-only mode: a closed network mode. a vm can only communicate with a host through vmnet1. This mode is suitable for conducting various network experiments in an independent environment. The di
To mount NFS, the first step is to enable the virtual machine to bridge the Internet. You do not need to check the box below the bridge Internet. The IP address and Host IP address must be configured in the same network segment.
Record the following steps:
I. I initially referred:
1), # ifconfig eth0 up (Note: After the system is installed, the default Nic is eth0. This command activates this Nic .)
2), # c

Virtualbox is a very good software and always uses default network settings (NAT), which is really convenient. But this time the host and the virtual machine need to communicate, so I found the network settings such as host-only, which can set an independent IP address to communicate with the
Modify the IP address of the machine where filenet is deployed. In addition to modifying the IP address of the machine as usual, you also need to configure two locations.
1. Run the command fn_edit to go to system config editor and modify the network address.
2. Modify the host configuration file hosts, change the IP address corresponding to the host name to
