I tried to work out all the kinks, but some additional tweaking may be needed. 127.0.0.1), username: testuser1, and password (from the password-nocrypt file): 3ySBG56Y and all should work. 4072 len: 13 data: cat cat password-nocryptįor this example, use your favorite ftp client with your host IP (ie. db_dump -d a /etc/vsftpd/password.db | grep len The example below is with the crypt=crypt appendices. If you remove the crypt=crypt from the PAM file, the clear text password is readable via db_dump -d a /etc/vsftpd/password.db. echo 'testuser1' > /etc/vsftpd/passwordĮcho 'testuser1' > /etc/vsftpd/password-nocrypt This one-liner replaces the following two lines. To append to the files rather than overwrite them, tee -a may be used. Using tee allows this script to create two files with the username. The output to two files, one for the encrypted password to be added to the database, the other for the non encrypted password to test the user. The goal here is to generate a random password using openssl rand then encrypting that password with openssl passwd -crypt. Since pam has two lines with crypt=crypt appended. It is worth explaining what is accomplished with the myval variable.

It had iptables installed and no firewalld. This test box is a CentOS 7.2 minimal install. This guide offers a script that demonstrates one way to setup a vsftpd server using PAM with a Berkeley DB while using virtual users with encrypted passwords. A virtual user cannot login to the Linux system and is considered more secure than using a “real” user whom can login to a Linux system. Vsftpd (“Very Secure FTP Daemon”) is an FTP server for Linux and supports PAM (“pluggable authentication modules”).
