Because of the needs of project development on an embedded platform, PPP dial-up Internet access is implemented on the ARM platform. Speaking of the PPP dial-up Internet access on this Linux platform, many people may feel very simple. There are many success stories on the Internet! Yes, you are right, but I still want to give my opinion, that is, this simple PPP dialing has been tossing me for a long time, and I am sorry to say it. However, it seems that this process has learned a lot and gained

Internet service provider. routers in the enterprise network connect to thousands of computers on a campus or enterprise. The router Terminal System on the backbone network is usually not accessible directly, they connect ISP and enterprise networks on the long-distance backbone network. The rapid development of the Internet poses different challenges to backbone networks, enterprise networks, and access networks. The backbone network requires the vr

technology can bring the following benefits to enterprises and service providers: Companies that adopt remote access have paid in advance all the fees for purchasing and supporting the entire enterprise remote access infrastructure;Companies can use the ubiquitous Internet to provide staff and business partners with secure and secure connections through a single network structure;For enterprises, the exists based on the dial-up VPN can enhance contact with users, business partners and suppliers
Whether in a school dormitory, an office, or even a home, several computers share a single ADSL device for dial-up Internet access. However, at present, many ISPs have begun to block network sharing, that is to say, to apply for an internet broadband, only one computer can access the Internet, which makes some friends even have two computers at hand, shared Internet access is also not possible. If you want to allow two computers to access the Internet at the same time, you must apply for two bro

The core of ensuring that your mail gets into your inbox and has high feedback is to "send the right message to the right person at the right time."Only when the information I send is of interest, need, relevance, and value to the recipient, will he be able to set the sender to a whitelist, move the message from the trash to the Inbox, Star Mail, open the message, click the link. Otherwise do more authentication settings, and a good ISP relationship w
After two days of downloading the isp of the at89s series single-chip microcomputer, I finally got it out. I encountered some problems in the process and wrote it down to help me remember it. The test board is the "USB + single-chip microcomputer + CPLD" Development Board. The isplay1.3 software is used to write a HEX file into the single-chip microcomputer through the ISP, but the system always prompts a

+ CDN is another way to build a small station. The rental cost of space investment in the flow, directly effective. But electricity and stability are not optimistic. In fact, CDN is not just doing web services, such as in Korea, most of the CND traffic is occupied by online games. Just imagine, if you can spread the CDN node in a wide range, it is necessary to have a game so many areas, occupy so many servers? The conclusion is that while the actual access to the connection and response spe
Speaking of STM32 's Flsah, our first reaction is to install the program, in fact, STM32 on-chip flash not only used to install the program, but also to install chip configuration, chip ID, bootstrap program and so on. Of course, flash can also be used to load data. Collected some of their own information, the information is summarized, do not want to see can be directly transferred to the back to see how to operate on it. Flash category According to the use, the flash in the STM32 slice is divi
are RIP, OSPF, and BGP. RIP, OSPF is an internal gateway protocol that applies to the operation of a single ISP's unified router protocol, and a network operated by an ISP is called an autonomous system (AS). BGP is a router protocol between autonomous systems and an external gateway protocol. Rip is the longest-growing router protocol and the simplest router protocol. It is the acronym for routing Information Protocol, which mainly transmits routi
Problem: In the process of using the Active Accessibility SDK, I get the IHTMLDocument2 pointer from a handle to a window. Is there any way to get the IWebBrowser2 pointer from the IHTMLDocument2 pointer? I tried it on two interfaces (IHTMLDocument2 and IWebBrowser2) with QueryInterface, but it didn't work. I also tried to get IOmNavigator * from Get_navigator using Netscape's HTMLWindow2 pointers. Also ended in failure. Please advise the master. Answer: This problem is usually a common probl

that computers within the network with the same IP address to access the Internet, While saving the IP Address resource, it can effectively protect the computer inside the network. The network environment is: LAN uses 10MB/S fiber to connect to the Internet as a metropolitan area network, as shown in the figure. The router chooses a Cisco 2611 with 2 10/100 MB/s adaptive ports. The IP address used by the internal network is 192.168.100.1~192.168.100.254, the IP address for LAN port fastetherne
This article describes how to configure dual-address dual-Egress and how to apply NAT configurations. I believe this article will help you. Environment Description: uses the Cisco2621XM + NE-1E module, which has two FastEthernet and one Ethernet port. Now we use Ethernet port 1/0 to connect to the internal LAN, simulating a policy route based on the original address when there are 100.100.23.0 255.255.255.0.0 and 100.24.0 255.255.255.0.0 clients internally. Fastethernet 0/0 simulates the first
. The best example here is the 128 k isdn, which uses two 56 K channels at the same time to achieve a speed of K. When the ISP provides such a service, two independent lines are configured to connect to the same IP address. You can see that, although there are EQL modules in Linux that allow you to use two data cards on the computer at the same time, unless the ISP provides the same IP address for the tw
