Why does vsFTPd prompt 530logincorrect error in linux?

This error was encountered when testing the Checkpoint VPN1R6x. This indicates that the connectivity between the client and the server is normal. But I can't figure out why. I thought it was a user name or password error. Label: VSFTP

Method 1:

The error message "vsftpd 530 login incorrect" appears during logon.

Solution:

Cp Path/RedHat/vsftpd. pam/etc/pam. d/ftp

Path is the source file directory for vsftp decompression

This is because we have enabled PAM for RHEL and/etc/pam is required for vsftp. d/ftp file (this file is not installed by default in the source code). Therefore, you cannot log on to the file without using an anonymous local outdoor user.

Method 2:

This error was encountered when testing Checkpoint VPN1 R6x. This indicates that the connectivity between the client and the server is normal. I thought it was a user name and a wrong password. Later, I Googled it and found that there was a problem with the server configuration.

Check/etc/vsftpd/user_list and/etc/ftpusers. This file has one line missing in/etc/vsftpd. conf:

Copy codeThe code is as follows:
Pam_service_name = vsftpd
$ Echo 'Pam _ service_name = vsftpd '>/etc/vsftpd. conf
$ Service vsftpd restart

530 error is eliminated!

The following is a more detailed method:
