Recently established in the lab's network environment, all host labs are connected via a switch. Want to be a gateway through the server (single card), using the Mentohust authentication extranet, and then other hosts in the intranet through this gateway to connect to the external network.1. First use mentohust on the server to connect to the extranet, and then enter the Ifconfig command at the terminal to view the acquired extranet IP:Eth0 Link encap: Ethernet Hardware address B8:AC:6F:D8

Div uses absolute positioning to change its position through top and left.
Because the top and left of the div may exceed the size
. The signal extension mode used by CDMA system is "direct sequence" extension. In order to extend the signal, the CDMA system uses a unique code called an extension code multiplied by the not-modulated baseband data, which contains a certain number of code pieces.
The resulting extended data is modulated to the carrier for launch, and the modulated carrier bandwidth is directly affected by the spread-spec

Broadband routers are currently one of the most commonly used routes. So I have studied the installation steps and problems that need to be paid attention to during the installation of broadband routers. I would like to share them with you here and hope they will be useful to you. The simplest configuration for using a Broadband Router to access the Internet is: a PC with a 10/100 M Ethernet NIC, a broadband access line that you have applied for and activated from the
As application developers and operators use standard-based information technology to create a new era of integrated and real-time communication, the prospect of telecom services is becoming more and more similar to that of the Internet industry. BEA Systems and Cantata Technology have been working closely together to enable operators in the Internet era to develop, apply, and deploy rich media services. BEA, the main application infrastructure provider, and Cantata, the world's leading independe

Coordinate System: What coordinate systems are there and what is the transformation matrix between them? (Mainly three coordinate systems and three corners)
Geographic coordinate system (N Series)
Take the coordinate system origin on as the aircraft center. The XN axis points to the north, the YN axis points to the day, and the Zn axis points to the east.
Simply put, XYZ is North Tiandong.
The relationship between the geographic coordinate system and the Earth coordinate system is the geographic

Real-time kinematic real-time dynamic difference method. This is a new and commonly used GPS measurement method. Previous static, fast static, and dynamic measurements all need to be calculated afterwards to achieve centimeter-level accuracy, the GPS-based GPS is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It uses the real-time dynamic real-time differential method of the carrier phase, which i

This knowledge is very important for employees, but its importance is not completely consistent with that of the company. Some knowledge is the most important for an employee, but may not be required by the Company. What knowledge management needs to do is to accumulate the most important knowledge of em
