The Construction of FTP Server and three access ways

Introduction to FTP Service

FTP service (File Transfer Protocol, file transfer protocol) is a typical application layer protocol of Cramp S structure, which needs to be implemented by server software and client software. It can be used not only in local area network but also in wide area network.

In Windows system, common FTP server software includes FileZilla Sener, Serv-U and so on. In linux system, vsftpd is a kind of FTP service software which is widely used in linux/UNIX field.

This experiment is mainly based on windows server 2016, as a server and accessed.

Three ways of access

There are three main ways to access the FTP server:

1. Browser login

two。 Disk access method (third-party software)

3. Command access

Construction of FTP

First, install the ftp service

At this point, the ftp service is installed, and the next step is to build the content.

Create a new user in server

Before the operation, you need to create a new folder for the service in advance in the server and place something for the later service.

I have created a new abc folder here.

Then open the iis Manager

Right-click the website to jump out of the menu

Fill in the ftp site name and select the physical path

Assign a local IP address to this service

Add authentication

The same method creates a new folder for the ro account and selects the physical path

Because the two ftp services are on the same server, the IP address is the same, and the added site cannot be started.

Dns services can be used to solve this problem

Open the DNS Service Manager after installing the DNS service

Right-click the normal search area to jump out of the menu

Right-click the newly created domain pop-up menu and select the new host as shown in the figure

As shown in the figure below

Then create a new ftp address for the second user in the same way

The ftp created after the dns creation is completed and before binding

Second ftp server

After verifying the success, the host network card sets the same network segment and fills in the dns address.

Test with a browser first

Second ftp

There are three ways introduced before, and browser access and construction have been introduced before.

Here is how to use third-party software

What I use here is FileZilla Client.

You can see that the files in the server have been displayed in the lower right corner, indicating that they can be accessed.

Then copy the file to your local desktop, modify it and upload it.

And look up the file just uploaded in the server.

Cmd command access

Directly call ftp192.168.5.55 to access the address of the ftp server

And then pop up and need a user name and password.

After input, the verification is successful.

Next, use the ls command to view the files inside.

Then use the get command to download something

The default download address is in the personal account.

You can see that the download is complete.

Detailed procedures for creating DNS server delegation and zone delivery

Before you configure the DNS server, you first install the DNS server role. Configuring the DNS server includes creating forward and reverse query areas, as well as configuring DNS server properties.

Configure the IP address and dns of host A.

Next, you need to create a new area.

Create a resource record. Host A record is a mapping of FQDN to IP addresses

The following is for domain name resolution.

Let's start creating delegated tasks.

Enter the delegated fully qualified domain name and the IP address of another delegated DNS server after the stand-alone is added

Finally, just click finish.

Configure the IP address of the No. 2 DNS server. And preferred DNS address

Create a DNS service on machine 2 as well
