Serv-u: Fast Building Powerful FTP server (iii)

FTP Server |serv-u The last two options are used to limit the maximum amount of time a user stays on an FTP server, and to specify the case of files and directory names on the server.

The other related options in this window are described in more detail later.

User account Management

One of the most basic tasks for users to use an FTP server is to add and manage user information. Open the Serv-u User Management window by selecting Users on the SETUP menu. The window can be divided into about two parts. The left window is used to display the users of all currently registered FTP servers. Select one of the users, and their detailed configuration information will be displayed on the right side of the window accordingly. If this is the first time you start Serv-u, only a system default account named "Default" will be displayed.

The following is a detailed description of the entire process of creating a new user account.

First click the NEW button at the far right of the window and enter the user name you want to create in the pop-up window that follows. The user name you enter appears in the User Name column to the right of the window. The user can also modify the name of the account established in this column.

The user can then enter the group name of the user group to which the account will belong or create a new group. The so-called group is the concept of people in order to facilitate the management of a large number of user groups introduced. We can divide a large number of individual users into different groups for unified management. Because users belonging to the same group have some common attributes, such as user password, root directory, etc., so users only need to individually set up individual accounts with special attributes, which greatly simplifies the management and maintenance of user accounts. It is important to note that the special user account "Anonymous" does not belong to any one user group.

In the subsequent password bar, you need to enter the password of the account number, if the user in the server's settings to select the Encryption password option (see above), then the password entered will automatically be stored in encrypted mode. The important point about the password is that only the first 8 characters of the input are valid, hoping to attract the attention of the vast serv-u users. In addition, if the user does not enter the corresponding password when creating the new account number, it does not mean that the user account does not have a password, serv-u will try to find out if the user account belongs to a user group and the user group has a uniform password. If Serv-u does not find the appropriate user group password, it will deny access to that user account. If the user does not want to specify the password for an account, as long as the corresponding account number in the password column input "$#@60;$#@60;" none$#@62;$#@62; " Can. An exception to this is the anonymous user account, which does not have a password, and serv-u only requires the user to enter any string that matches the format of the mail address.

In the "Home" column, set the FTP user's root directory, which is the home directory that the user automatically resides in after a successful logon. Each user account must have its own root directory, otherwise serv-u will deny access to that user account. Of course, if the account belongs to a group and the user group already has a common root, then the user does not have to repeat the settings for each account in the user group. Users should be aware of the need to use the full path, including the letter letter, when entering the address of the root directory.

In the "Note" column, the user can choose to enter some text for the account number to assist in future reference.

The largest column to the right of the user's window is used to set the access rights of the account, determining which files users can access and how to access them. Serv-u the user's access rights according to the file and directory categories. Specifically, it includes:

Access rights to files:

READ: Allows users to download files;

WRITE: Allows users to upload files, but not the right to make changes to the file, delete, or rename;

APPEND: Allows users to attach to existing files, and users with APPEND permissions automatically have write

Permissions

Delete: Allows the user to make changes to the file, rename it, or delete it. Users who have the Delete permission automatically hold

Have write and append permissions;

EXECUTE: Allows the user to run the executable file through FTP. For example, a user can run DOS or Windows remotely

Program.

Access permissions to the directory:

List: Allows users to obtain a directory listing;

Make: Allows the user to create a new subdirectory under the root directory;

Remove: Allows the user to delete subdirectories under the root directory.

INHERIT: When this option is selected, the access rights set for a directory are automatically owned by all subdirectories in the directory

Inherited.

After you have completed all of the above settings, click on the "STORE" button and the newly created user account will be saved in the FTP server.
