The main background is as follows: DNS and HTTP hijacking need to be monitored, but many DNS servers refuse to respond to requests from non-local operators in the region, so we have to distribute the monitoring sites to different places. In fact, to do this, use nagios's distributed architecture. I wrote

In actual application, DNS resolution errors may occur, that is, when we access a domain name, it cannot be resolved to an IP address, however, you can directly enter the website IP address for normal access, which is caused by a DNS resolution failure. This phenomenon has a high probability of occurrence, so this article will teach you some basic troubleshooting methods from scratch. 1. What is a

DNS is one of the core Internet protocols.

DNS recursive query and iterative query Summary There has always been confusion about the "recursion" and "iteration" approaches to DNS queries. Most people just tell you. "DNS clients request recursive queries to DNS servers," and "query requests between DNS servers are i

One of the most important components of any current TCP/IP network is the DNS server. A number of things a DNS server can accomplish, such as parsing an Internet URL into an IP address, resolving the host name on the local network, and providing the infrastructure on which the Windows Active Directory depends. Therefore, deploying a DNS server is not a very simpl

The probability of this phenomenon is relatively large, so this article will be from the beginning of zero to teach readers some basic troubleshooting DNS troubleshooting methods. first, what is a DNS resolution failure? Generally speaking, as we visit the www.jb51.net,www.kanshule.com these addresses are called domain names, and it is well known that any host in the network is the IP address to identif

Each IP address can have a host name that consists of one or more strings separated by a decimal point. With the hostname, do not memorize each IP device IP address, just remember the relative intuitive meaningful host name on the line. This is the function that the DNS protocol will perform.Today we will discuss DNS servers, especially Linux DNS servers, and how

Windows2000 as a brand new operating system, its biggest feature is the introduction of Active Directory, and the Active Directory is one of the biggest feature of the DNS and Active Directory tightly together. So how do they work together and what do they do? This often becomes a puzzle for beginners. In this paper, we will make a brief discussion on the relationship between the two, hoping to help you. A The difference between the two The combinatio

Definition: DNS Spoofing is a spoofing behavior by attackers impersonating domain name servers. Principle: If you can impersonate a Domain Name Server and set the queried IP address as the attacker's IP address, you can only view the attacker's homepage on the Internet, instead of the website you want to obtain, this is the basic principle of DNS spoofing. In fact, DN
