Shulou(Shulou.com)06/02 Report--

This article will explain in detail the service ports and protocols commonly used in network services. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

When we do the ITer of network services, we often encounter some service port numbers when troubleshooting problems.

Maybe we know some common service port numbers.

For example, HTTP is 80, FTP is 21, Telnet is 23, remote desktop is 3389, and so on.

In fact, when we go to Baidu, we have a total of 65536 port numbers. Different ports provide different services. Of course, the corresponding protocols are also different, including connection-oriented (TCP) and connection-oriented (UDP).

Among them, port 0-1023 is used as a well-known port number, which is some of the services we often come into contact with (like the above mentioned).

All right, now I would like to post some commonly used services and port numbers for you to collect and learn:

Some students wonder, how do you know so many port numbers?

Yeah, how do I know so many port numbers? , I can't brag, so I'm going to tell you honestly.

Listen up.

In fact, this file can be found on all computers installed with Microsoft (I'm not sure about pre-XP systems such as 98). The specific path is the services file under C:\ Windows\ System32\ drivers\ etc. In fact, there are some other files under the etc folder, such as hosts files, which are used to modify domain names and IP parsing.

For example, you can add a 114.112.94.203 www.icanmusic.com to the hosts file to visit the www.icanmusic.com site.

Don't ask me why you can access it directly without adding this resolution, because the blogger is hard-pressed, and the DNS server used is internal to the unit, so there is no way to access it directly, so you can only change the configuration on your computer without adding parsing on the DNS server.

Another point is that when a host visits a site, the first thing is to check whether there is a corresponding entry in the hosts file, and then it will go to the DNS server to apply for parsing.

This is the end of the article on "what are the service ports and protocols commonly used in network services". I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, please share it for more people to see.
