FTP Server account management in Serv-U

We have already introduced the FTP server setting process in Serv-U. Next, we will parse the relevant content of its account. First, let's take a look at the user account management function of this software.

User Account Management

The most basic task for a user to use an FTP server is to add and manage user information. Select "USERS" from the "SETUP" menu to open the Serv-U user management window. This window can be divided into two parts. The window on the left shows all registered FTP Server users. If you select any user, the detailed configuration information is displayed on the right of the window. If Serv-U is started for the first time, only one DEFAULT account named "DEFAULT" is displayed. The following describes in detail the entire process of creating a new user account.

First, click the "NEW" button on the rightmost side of the window, and enter the username to be created in the pop-up window. At this time, the entered user name will appear in the user name column on the right of the window. You can also modify the account name in this column.

Then, you can enter the group name of the user group to which the account belongs or create a new group. Groups are concepts launched to facilitate the management of a large number of user groups. We can divide a large number of individual users into different groups for unified management. Because users in the same group share some common attributes, such as user passwords and root directories, you only need to set individual accounts with special attributes, this greatly simplifies the management and maintenance of user accounts. Note that the special user account "Anonymous" does not belong to any user group.

In the subsequent password field, enter the account password. If you select the password encryption option on the server, see the previous article ), the entered password is automatically stored in encrypted mode. It is important to note that the password is valid only for the first eight characters, and is expected to attract the attention of the majority of Serv-U users. In addition, if the user did not enter the corresponding password when creating a new account, it does not mean that the user account has no password, serv-U will try to find whether the user account belongs to a user group and the user group has a unified password. If Serv-U does not find the user group password, access to this user account is denied. If you do not want to specify the password for an account, you only need to enter "<>" in the password field of the corresponding account. One exception to the above situation is the Anonymous user account, which has no password. Serv-U only requires the user to enter any string that conforms to the mail address format.

In the "HOME" column, set the root directory of the FTP user, that is, the starting directory automatically located after the user successfully logs on. Each user account must have its own root directory. Otherwise, Serv-U rejects access to this user account. Of course, if this account belongs to a group and the user group has already set a common root directory, you do not have to reset each account in the user group. When entering the address of the root directory, you must use the full path, including the drive letter.

In the "NOTE" column, you can enter some text to help you with your account for future reference.

The largest column on the right of the user window is used to set the account access permissions, so as to determine which files the user can access and how to access these files. Serv-U classifies user access permissions by file and directory. Specifically, it includes:

Access Permissions to files:

READ: allows users to download files;

WRITE: allows users to upload files, but does not have the right to modify, delete, or rename the files;

APPEND: allows you to attach existing files. Users with APPEND permissions automatically have the WRITE permission;

DELETE: allows users to modify, rename, or DELETE files. Users with the DELETE permission automatically have the WRITE and APPEND permissions;

EXECUTE: allows you to run executable files through FTP. For example, you can remotely Run DOS or Windows programs.

Access Permissions to directories:

LIST: allows users to obtain the directory LIST;

MAKE: allows you to create new subdirectories under the root directory;

REMOVE: allows you to delete subdirectories in the root directory.

INHERIT: After this option is selected, the access permissions set for a directory are automatically inherited by all subdirectories in the directory. After completing all the preceding settings, click the "STORE" button to save the newly created user account to the FTP server. Other options in this window will be described in detail later.
