Vsftp virtual user settings in linux

Vsftp virtual user settings in linux-Linux Enterprise Application-Linux server application information. For details, refer to the following section. I used rpm for packaging on as4. The installation steps are not easy!

1. Create a virtual account and User Password File

A vi logins.txt

B. Generate the authentication File For vsftpd.

Command db_load-T-t hash-f./logins.txt/etc/vsftpd/vsftpd_login.db

C. Create the PAM Configuration File required by the virtual user.

Create a vsftpd. vu file manually

* *** Important *** uth required/lib/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login

* ** Important ** account required/lib/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login

Create a system user account used by all FTP virtual user accounts, and set the permissions for the root directory of the account.

# Useradd-d/home/ftpsite virtual

# Chmod 700/home/ftpsite

F. Set the vsftpd. conf configuration file.

Add the virtual user configuration content to the configuration file.

Guest_enable = YES

Guest_username = virtual

Pam_service_name = vsftpd. vu

Restart the vsftpd service program.

Set different permissions for virtual users

Set the main configuration file.

Add the user configuration file directory settings in the vsftpd. conf file.

User_config_dir =/etc/vsftpd_user_conf

Create a user configuration file directory.

Run the mkdir command to create a directory for the user configuration file.

# Mkdir/etc/vsftpd_user_conf

Create a separate configuration file for the virtual user.

The user configuration file name is the same as the user name.

/Etc/vsftpd_user_conf/mike

/Etc/vsftpd_user_conf/john

The content is as follows:

Anon_world_readable_only = NO indicates that you can browse the FTP directory and download files.

Anon_upload_enable = YES indicates that you can upload files.

Anon_mkdir_write_enable = YES indicates that the user has the permission to create and delete directories.

Anon_other_write_enable = YES indicates that the user has the permission to rename and delete files.

No configuration items are configured according to vsftpd. conf by default.

# When virtual_use_local_privs is set to YES, the virtual user has the same permissions as the local user. If it is set to NO, the virtual user has the same permissions as the anonymous user.
Virtual_use_local_privs = YES
# Pam Authentication file name
Pam_service_name = vsftpd
# Restrict local users to the Home Directory
Chroot_local_user = YES
