I have set up a server on Linux in four steps: Install Configuration Start the service Use For centos, I Like Yum and Yum, which can automatically parse dependencies. Therefore, installation is generally normal and it is easy to start the service. Generally, service XX start is used, it is easier to use, and the trouble is complicated in the configuration file. The Configuration File. at the end of conf, most of them are in the/etc directory. For the DNS server, I installed bind and

If you need to solve the DNS hijacking problem, you can change your domain name resolution server to a foreign one, such as OpenDNS. (For details, refer to "use OpenDNS to solve DNS domain hijacking" in the moonlight blog.) or Google DNS (For details, refer to the moonlight blog "Google launch

NetScaler system can block unwanted requests and reduce the risk of attacks on the server. This feature can also parse http GET and POST requests and filter out known error signatures to better protect against HTTP -based server attacks such as Nimda and Code A variant of the Red virus.

Dnscrypt is a tool released by OpenDNS that ensures security between the client and the DNS server. Dnscrypt, which runs as a DNS proxy, focuses on communication security between the client and the first-level DNS server, and can cache DNS resolution. In short, the Dnscrypt is able to encrypt the DNS query communication process before the native to the DNS server, thereby preventing DNS hijacking by the network service provider.

server is disabled, it is started. If/etc/resolv is enabled. check the conf file and you will be surprised to find that the content of this file has been cleared, so you cannot go to the Internet and need to reconfigure it. To avoid the above problems, you can use the following methods: Add DNS to/etc/resolvconf/resolv. conf. d/base and/etc/resolv. conf respectively. If you do not have a public IP address or try to use an external IP address of the current network, you can use the following two
