packet for special purposes.2. Why Nat?Let's see under what circumstances we need to perform Nat.Assume that an ISP provides Internet access services in the campus. To facilitate management, the IP addresses assigned by the ISP to the campus users are all pseudo IP addresses, but some users require that their WWW servers be set up to publish information, in this case, we can use NAT to provide such service
FTP commands are one of the most frequently used commands by Internet users. Whether using FTP in DOS or UNIX operating systems, a large number of FTP Internal commands are encountered. You are familiar with and flexible to use FTP Internal commands, it is very convenient for users. For users who use dial-up Internet access now, If the ISP provides shell and can use nohup, ftp will be the most cost-effective download method. The ftp command line forma
Remote access technology is worth learning. Many people may not understand the basic knowledge of remote access technology. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you more things. Remote access technology allows home users, mobile users, and remote office users to access resources on a company network or Internet Under ISP conditions. The remote access technical method should allow re
For general users, I am not very familiar with vro settings, so I have studied the specific operations on vro settings. I will share them with you here, hoping to help you. Someone may ask: What is a route? Can I use the route entry to obtain the route entry? Okay, let me ask you, if you have more than two PCs, how will you enable them to access the Internet at the same time?
"Let a proxy server" OK, so this proxy service can not be shut down, can not crash, otherwise it will be tired of others.

Environmental Requirements:A machine with CentOS6.5 installed;A twisted pair that can be used normally ...An ISP-provided account that can be used normally;A dial-up interface that can access the ISP's network ...Dial-up software an
Palindrome Partitioning IIGiven A string s, partition s such that every substring of the partition are a palindrome.Return the minimum cuts needed for a palindrome partitioning of s.For example, given s = "aab" ,Return 1 since the palindrome partitioning ["aa","b"] could be produced using 1 cut.The method of dynamic programming can first get isp[i][j], that is, whether the string, from I to J is a palindrome isp
Sieve method to calculate prime number:the number of primes in n is evaluated. First use 2 to sift, that is, 2 left, the number of 2 is removed, and then the next prime number, that is, 3 sieve, 3 left, the multiples of 3 is removed, then the next prime number 5 sieve, 5 left, the multiples of 5 are removed; Thus, we can write the basic version of the Sieve method to seek the vegetarian:Const intMAXN =102410240;BOOLISP[MAXN];voidinit () {memset (ISP,t

For a typical family, the ISP is usually the "cable company". When your browser accepts a request to go to www.github.com, it does not know where to look for www.github.com, so

Tp-link Router Configuration Guide
The basic configuration of the router, so that the computer through the router to share the Internet, the process is relatively easy to achieve; The following sections of this document mainly describe the following parts:

In our commonly used Windows XP operating system, the default MTU value is 1500, which is a standard Ethernet setting value that is not suitable for broadband networks, whereas the MTU of General ADSL broadband is between 1450 and 1492, The discrepancy of the MTU between the system and ISP will directly result in the data in the network transmission process of continuous subcontracting, packaging, waste valuable transmission time, but also seriously a

On the author's bulletin board, I saw several friends asking if you could use multiple dial-up lines to improve Internet speed on the Internet. The best example here is 128KISDN, which uses two 56K channels at the same time to achieve 128K speed. When an ISP provides such a service, two separate lines are configured to connect to the same IP.
You can see that while Linux has
The basic configuration of the router, so that the computer through the router to share the Internet, the process is relatively easy to achieve. The following sections of this document are described in detail:
1, collect and judge the information, prepare for configuring the router;
2, enter the router management interface, configure the router;
3, the configuration process of simple fault location exclusion;
Let's get started, get to the point!

-link application switch mainly uses the following centralized method to deal with outflow flow.
--smartnat for intelligent address management of outflow flow, linkproof Branch Multilink application switch uses the algorithm called Smartnat. When a router (ISP) is selected to transfer out of traffic, the Linkproof Branch Multilink application switch selects the address provided by the ISP. If Linkproof cho

One of the common network faults is access line faults, which may be ISP terminal equipment faults, cable faults, or client Modem faults, which are not hard to see. If you use a multi-Wan port router, apply for multiple lines and use multiple Modem lines, these lines can also be of different carriers, such as China Tel
Remote access technology allows home users, mobile users, and remote office users to access resources on a company network or Internet Under ISP conditions. The remote access method should allow remote users to access a network just as they connect directly to the network and use the same protocol. Access to the company network is discussed below, but there are many similarities with access to the Internet using an
I believe many of my friends know about the PPP protocol. Here we will explain the problem about Linux PPP settings. Now let's start with Linux dial-up Internet access. I hope this will help you. The details are as follows:
How to dial up Internet access in Linux PPP settings
Set PPP on a Linux server so that it can dial and connect to the ISP to connect the computer to the Internet. The following describes how to configure the Linux PPP client.

Open the Sygate server console, as shown in. Click the Advanced button to enable the extension settings and set the server.
The left side of this window shows the network connection status, the upper half of the bandwidth and data volume used by the internal computer for Internet access, and the lower half of the server Internet connection status. Click the Configuration button to enter the Sygate settings window, as shown in.
