Discussion on the problem of the search engine indexed by the server ban ping

PING (Packet Internet grope), Internet Packet Explorer, for testing http://www.aliyun.com/zixun/aggregation/18415.html "> Network connection Volume program. Ping sends an ICMP echo request message to the destination and reports if the desired ICMP echo response is received.

It is used to check whether the network is smooth or network connection Speed command. As an administrator or hacker living on the web, the ping command is the first DOS command that must be mastered, which uses the principle that the machine on the network has a unique IP address, we send a packet to the destination IP address, and the other side returns a packet of the same size, According to the returned packets we can determine the target host's existence, can initially judge the target host's operating system and so on.

Ping is an executable command brought by the Windows family. It can be used to check whether the network is connected, and it can help us to analyze and judge the network fault well. Apply format: Ping IP address. The command can also be used with a number of parameters, in particular by typing ping to enter to see detailed instructions.

Recently in a webmaster forum to see an article, shut down the server ping service can prevent some hacker attacks, so some server administrators in order to reduce the risk of hacker attacks, so that the ping service to shut down. This allows the site to be accessed normally, but when you ping the Web site, it displays a timeout and no return results. But for the ping value, the site can be Baidu and Google and other search engines included, a lot of people say different, some said to include no impact, but also some said the impact is not, in fact will affect, I am not very clear, I can only from the situation I encountered to analyze.

July bought a space, July 30 put a website to go in, beginning very satisfied, August, the major search engines are good to me, have recorded, take Baidu, to August 28 included more than 140 pages, (statement did not cheat), but a very bad situation is, August was hung a few times horse.

Starting in September, the administrator of the Ping service to turn off, the situation is not the same as before, hanging horse phenomenon is indeed less (do not know to close the ping service has no relationship, the site program has not changed), on the inclusion of the situation, Google or normal, included in the number of pages slowly increased, But since the administrator close Ping, to now has been two months, Baidu has not been included in the site of a page, the last included in the August 28, October even before the inclusion of the previous.

Feel a bit strange, so using software to check the same host under the other sites, find more than 10, and then check the site's collection, the situation and my site is exactly the same, or Baidu is included as 0, or Baidu last included date is closed before the ping, Google's included basic are not affected. Check the site log, found that Google has come, but Baidu spiders do not come, according to the above data, from the surface and a variety of data to see, Ping is not close to Google included not too much impact, but the Baidu included, the impact is very serious, but in the end is not a ping service for the strange, or other reasons, I'm afraid only Baidu spiders know! But I still want to tell you webmaster, it is best to buy ping to the space!
