, so we can use the same email for testing. Some of these anti-spam tools allow you to train filter rules. We trained filter rules in a few days: in hundreds of emails, we pointed out which are spam and which are not spam. After this process, we waited until we received nearly 500 new emails before the formal test began. We let every tool program process the same email to test their ability to distinguish normal and spam (we determine spam. However, it should be noted that the White List, blackl

In XP, I had a long time ago when I was very upset with the DNS hijacking of China Telecom. I always transferred Google.com to Google.cn, and got the wrong domain name and gave it a "114 search". The entire super hooligans of China Telecom. Therefore, in XP, it is easy to set all DNS servers as OpenDNS servers. It is also very easy to set in Ubutu. You can also set it in Ubuntu, such as "Main Menu", "system", "system management", and "network". In "DN

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

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. DNS requests and retu

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

IP addresses that cannot be completely blocked. If they are completely blocked, they will affect Google's normal use. (3) Illegal Information in Google Docs must be blocked. These three reasons have promoted the development of new interception methods. According to speculation, this method is like this: when the client sends an encrypted DNS resolution request, the DNS monitoring end immediately sends a reset signal once it finds that the request is from Google Docs. For general unencrypted DNS

Using Firefox and other browsers to surf the internet in Ubuntu is much slower than surfing the Internet in Windows, but careful people will find that the slow time is spent on DNS lookups. Then we can cache DNS in the native computer, that is, a DNS proxy server is set up natively. Commonly used software is bind, Djbdns, DNSMASQ and PDNSD. Let us say, with PDNSD to set up a permanent DNS proxy server, so-called "permanent", that is, after the system restart, the native cache DNS still exist, no

At present, the more authoritative public DNS server providers have the Opendns,google-Dns,norton DNS, what are the actual access speeds of these DNS servers? This is directly related to the speed of our Internet access, after all, the fast speed is the king. The author compares the ping values of these DNS servers through 11 servers in the country with representative cities, and provides some references for the Internet setting for the national netiz

DNSMASQ provides DNS caching and DHCP service functionality. As a domain name resolution server (DNS), DNSMASQ can increase the speed of connection to visited URLs by caching DNS requests.
