operating environment

OS: Redhat 6.5

IP Address: 192.168.10.128

Hostname: zred

Operating System: Win 7

IP address: 192.168.10.10

Confirm that the two hosts are interconnected.

Requirement: add a virtual user to access ftp.

First we restart the service.

Add Virtual Account

Edit a file vuser

[root@localhost vsftpd]# vim /etc/vsftpd/vuser

Put two users in it.

Convert vuser to database file for PAM recognition

[root@localhost vsftpd]# db_load -T -t hash -f vuser vuser.db

And then modify the file permissions, can strengthen security, so as not to be peeped at by others.

Create a user to specify the home directory for vuser/opt/vuser and log in without using shell

[root@localhost vsftpd]# useradd -d /opt/vuser -s /sbin/nologin vuser

Edit pam authentication module to support virtual user login

[root@localhost vsftpd]# vi /etc/pam.d/vsftpd.vu

Add two sentences to it.

auth required pam_userdb.so db=/etc/vsftpd/vuser //a will be lost

account required pam_userdb.so db=/etc/vsftpd/vuser /* The two files vuser is not an ordinary file but the vuser.db database file created just now. */must be omitted here.

Edit the master profile and add permission statements for guest users at the end

guest_enable=YES

guest_username=vuser

pam_service_name=vsftpd.vu

Restart the service and try to log in

We can also specify a separate configuration folder

Insert at the end of the main configuration file:

user_config_dir=/etc/vsftpd/vu_dir /* Separate user configuration folder */

create a profile

mkdir vu_dir

vi /etc/vsftpd/vu_dir/tom /* Create a user profile in the configuration folder */

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