How to add/delete FTP users and set permissions in Linux

This article introduces the knowledge about how to add/delete FTP users and set permissions in Linux. During the operation of actual cases, many people will encounter such difficulties. Next, let the editor guide you to learn Let's see how to deal with these situations! I hope you read it carefully and learn something!

1. Environment: ftp is vsftp. The user name is set to test. The restricted path is /home/test
2. Create a new user: under the root user:

1. useradd -d /home/test test #Add user test, and set the home directory of test user as /home/test

2. passwd test #Set password for test user

3. Change the corresponding permission settings of the user:

1. usermod -s /sbin/nologin test #Limited user test cannot telnet, only ftp 2. usermod -s /bin/bash test #User test returns to normal 3. usermod -d /home/test test #Change the home directory of user test to /test

4. Restrict users to only access /home/test, not to Other paths

Modify /etc/vsftpd/vsftpd.conf as follows:

1. chroot_list_enable=YES #Restrict access to its own directory 2. 3. # (default follows) 4. 5. chroot_list_file=/etc/vsftpd/vsftpd.chroot_list

Edit vsftpd.chroot_list file, add restricted users, one line for each user name

After modifying the configuration file, don’t forget to restart the vsftpd server

1. [root@localhost]# /etc/init.d/vsftpd restart

5. If you need to allow users to change their passwords, but they do not have permission to log in to the system via telnet:

1. usermod -s /usr/bin/passwd test #Users will directly enter the encryption interface after telnet

6. If you want to delete User, use the following code:

1. #Under the root user: 2. userdel -r newuser 3. #Under ordinary users: 4. sudo userdel -r newuser

Because the user needs to be completely deleted, so add the -r option, and delete the user’s home directory and Mail directory deletion.
