FTP Service setup in Linux--3. Virtual users

Operating Environment

1 Operating system: Redhat 6.5

IP Address: 192.168.10.128

Host Name: zred

2 Operating system: Win 7

IP Address: 192.168.10.10

Verify that two hosts are interconnected.

Requirement: Add a virtual user to access FTP.

First, we restart the service.

Add a virtual account

Edit a file VUser

[Email protected] vsftpd]# Vim/etc/vsftpd/vuser

Write two users in

Convert the VUser into a database file for Pam identification

[Email protected] vsftpd]# db_load-t-t hash-f vuser vuser.db

Then modify the file permissions, you can enhance security, so as not to be seen by others.

Create a user to specify home directory for VUser/opt/vuser do not use shell login

[Email protected] vsftpd]# useradd-d/opt/vuser-s/sbin/nologin vuser

Edit Pam authentication module to support virtual user login

[Email protected] vsftpd]# Vi/etc/pam.d/vsftpd.vu

Add two sentences to go in

Auth Required pam_userdb.so Db=/etc/vsftpd/vuser//a will be lost
Account Required Pam_userdb.so db=/etc/vsftpd/vuser/* Here two files VUser is not a normal file but the Vuser.db database file that you just created, you must omit the do not write */

Edit Master profile, add Guest user's permission statement at last line

Guest_enable=yes
Guest_username=vuser
Pam_service_name=vsftpd.vu

Restart service, try to login

We can also specify a separate configuration folder

Insert at the end of the main configuration file:

User_config_dir=/etc/vsftpd/vu_dir/* Individual User Configuration folder */

Creating a configuration file

mkdir Vu_dir
Vi/etc/vsftpd/vu_dir/tom/* Create a user profile in the configuration folder */

anon_umask=022/* Specify permissions to upload files */
