First, the preface


1. What is intranet

Intranet computers use NAT (Network address Translation) protocol to access the Internet through a public gateway. Intranet computers can send connection requests to other computers on the Internet, but other computers on the Internet cannot send connection requests to computers in the intranet, so it is not possible to establish an FTP server in the usual way.

The IP address of intranet has the following 3 kinds of forms:

10.*.*.*
172.16.*.* to 172.31.*.*
192.168.*.*

2. Two ways of intranet building FTP

2.1, Dynamic domain name and virtual Private law:

Suitable for conditions: No access to the gateway server, can not do professional port mapping.

such as: Branch mai network dynamic domain name and virtual dedicated services within the network Professional Edition. (Truehost).

2.2. Port Mapping Method:

Applicable conditions: To be able to access the gateway server, and as a port mapping.

such as: port mapping software Porttunnel.

3, about the domain name

Domain name can solve the problem of no fixed Internet IP. such as "peanut shell" and so on.

The method mentioned in above 2.1 does not require additional domain name services because the service itself has been provided.

4. About Serv-u

A common tool software for establishing FTP.

Ii. establishment of the FTP program
Programme I, Serv-u

Applicable conditions: Have fixed Internet IP address.

Plan II, serv-u+ peanut shell

Applicable conditions: There is a fixed Internet IP address.

Solution Three, serv-u+ peanut shell +porttunnel Port mapping

Applicable conditions: Intranet IP, can control gateway server and set port mapping.

Programme IV, Serv-u+truehost

Applicable conditions: Intranet IP, can not control the gateway server.

Second, installation and general settings

1. Run the Setup program
Yun_qi_img/30_406.1.jpg

2. Select Installation path

Installation path This is usually overlooked because everyone has a bad habit of installing all programs under the default%system%\program files\. Ordinary software is not a big problem, but this is very dangerous to the service class software and the security class software, by default user's permission to program files is accessible and can be run, for hackers, you can turn off your firewall virus wall without having to get administrator privileges. The need to share the file, very simple to achieve the goal of complete intrusion.

Therefore, it is advisable to install the serv-u into a safe directory with a set of permissions.
Yun_qi_img/30_406_1.1.jpg

Terror of the Authority
Yun_qi_img/30_406_2.1.jpg

This is the normal Windows Media Player directory attribute (visible serv-u installed here ...)

3. Simple Wizard after installation

After installation, Serv-u will ask you a few questions, including: New domain IP, domain description, service port, anonymous user under this domain, anonymous user's directory, build other users, etc.
Here you can choose nothing, exit serv-u after installing Serv-u patch

Yun_qi_img/30_406_3.1.jpg

After the patch is installed, the serv-u becomes the Chinese version, and the next setting will be easier to understand and very clear.

Serv-u supports the creation of multiple domains, that is, multiple FTP servers, but these servers cannot use the same port at the same time, each server must use a different port, the computer has 65,535 available network ports, minus the port reserved by the system, users can choose the port there are many.

Here's how to set up an FTP server in an empty serv-u.

Third, the establishment of FTP server
Yun_qi_img/30_406_4.1.jpg

Run serv-u, expand Local Server, right-click New domain, or press Insert directly.

1. Server IP for new domain
Yun_qi_img/30_406_5.1.jpg

As the figure shows: if you use a dynamic IP address, you can leave it blank.

2. Add domain name of new domain

Yun_qi_img/30_406_6.1.jpg

Enter the newly established domain name description and enter it at will, these are just logos.

3. Select Service port

The default FTP port is 21, you can select a different port, but you need to notify visitors.

Yun_qi_img/30_406_7.1.jpg

4. Select a domain type

You can choose the registry if you can access more than 500 people at the same time.
Yun_qi_img/30_406_8.1.jpg

Yun_qi_img/30_406_9.1.jpg

The DNS option enables you to request a dynamic Domain name Interpretation service (30 days) in toz.com.

5. Add User

Here you can add two kinds of users, one with anonymous access, the other being the user name and password you must enter to access the FTP service. \ Anonymous Both of these users can be given different permissions.

A. Adding anonymous users

Similar to adding a domain name, right-click the user under the domain tree to select Add user or select a user under the domain tree and press Insert.

Enter the default name of the anonymous user Anonymous, Note: Serv-u automatically identifies the user named Anonymous as an anonymous user.
Yun_qi_img/30_406_10.1.jpg

Input Anonymous

Yun_qi_img/30_406_11.1.jpg

Specify accessible Directory
Yun_qi_img/30_406_12.1.jpg

Lock Directory

B. Adding a permission constraint user

Permission constraint users must enter a username and password before they can log on to the FTP server.
As with adding anonymous users, the steps are roughly the same.

6. Set User permissions

This article mainly describes the user's permissions, which include file permissions, directory permissions, subdirectory permissions. File permissions include read (read), write (write), append (Append), delete (delete), execute (execute).

Directory permissions include: list, create, delete (delete).

subdirectory Permissions are inherited (Inherit).

Yun_qi_img/30_406_17.1.jpg

File permissions:

READ: Gives users permission to read (download) files.
Write: Gives the user permission to write (upload) files.
Append (Append): Allows the user to append files.
Delete: gives the user permission to delete files.
Execute: Gives the user permission to execute the file. Please note: This permission is very dangerous, once open this permission, the user can upload the malicious virus file and execute the file, will cause the computer to make the incalculable break fast.

Directory Permissions:
List: Give users permission to browse the file list, if open read the county but turn off list permissions, and will not affect the user's download, as long as the user knows the detailed download path on the line.
Create: Allows a user to create a directory to create a folder.
Delete: Allows the user to delete a directory, but does not allow the deletion of non-empty directories.
Sub-directory Permissions:
Inheritance (Inherit): As with NTFS inheritance, users can access the next level of directories according to the permissions of this level of directory.


Four, advanced settings

1. Use of user groups

Like Windows 2000/nt, Serv-u has a similar user group management mechanism that requires no further redefinition of permissions for each user simply by establishing a group with the required permissions.
Assuming that the existing Movie-con, MOVIE-ADV, and Upload groups, the Movie-con organization allows users who know the detailed download path to download the file, the Movie-con group only needs to have file read and subdirectories to inherit two permissions.
Yun_qi_img/30_406_18.1.jpg

Movie-con Group with R---I (read and inherit) permissions only
The MOVIE-ADV group allows users to browse the entire FTP server to select files that need to be downloaded, and the MOVIE-ADV group requires file reads, directory listings, and subdirectories to inherit three permissions.
Yun_qi_img/30_406_19.1.jpg

MOVIE-ADV group with file read, directory list, subdirectory inheritance
Upload groups need to have upload permissions, you should give file writes, directory listings, and subdirectories to inherit three permissions.
Yun_qi_img/30_406_20.1.jpg

Only Upload groups with file uploads, directory lists, and subdirectories inheriting permissions
When a group of appropriate permissions is established, you can add a user name to the group
Yun_qi_img/30_406_21.1.jpg

Users listed in the Movie-con group Movie have their own user rights and have group permissions

2. Modify Server port

The port (bundle 0–65535) of the FTP server can be changed in the domain properties that appear after the domain is selected, and the default value is 21.

Yun_qi_img/30_406_22.1.jpg

3. Send a message to a visitor

You can send a message to a user who is accessing your FTP, such as: Hello, Welcome to login, 30 minutes later I will disconnect the server, please use the FTP to support the continuation of the download software access. And so on, the greeting messages can be received by the visitor.
Select the field, select "Windows" on the menu bar, select "Message" From the Drop-down menu, or press F2 directly, but it must be in the case of a selected domain.
Yun_qi_img/30_406_23.1.jpg

In the message window that appears, click "Broadcast Message" or press the key combination ctrl+b the message's compose window appears
Yun_qi_img/30_406_24.1.jpg

Yun_qi_img/30_406_25.1.jpg

You can also stand alone-to send a message to a visitor, select the field, and then select the activity:
Yun_qi_img/30_406_26.1.jpg


4. Block visitor IP and kick people

If you like, you can block an IP segment or an IP, the server will deny access from this IP segment or this IP.
Select the domain, select the settings for the domain, and then select IP Access.
Yun_qi_img/30_406_27.1.jpg

Prohibit access from 218.19.*.*-218.20.255.255 IP Segments
You can also kick people individually, select the activity under the domain, select the user in the user list, and choose to kick the user in the right-click menu.

5. Set the server reply message

These replies will be displayed in an event dialog for the visitor's FTP download software.
Yun_qi_img/30_406_29.1.jpg

6. Limit the upload download rate of visitors

Too much user access has robbed you of bandwidth, even browsing the web has become as slow as a turtle, you need to limit the rate of upload and download visitors.
Select the user you want to restrict, and you can specify the user's speed at the maximum upload/download speed in the general:
Yun_qi_img/30_406_30.1.jpg

7. Set advanced settings for the entire server

You can set advanced settings for the entire server and select settings under the server name (default is local server):
