1. 如题， FTP上传时抛vftpuser.db: file size not a multiple of the pagesize 530 Login incorrect.

STATUS:>  	[2020-09-02 20:51:47] Connected. Authenticating...
COMMAND:>	[2020-09-02 20:51:47] USER root

研究了好久，发现是 vftpuser.db文件有错。
解决办法：

1. 定位到vftpuser.db所在的父目录(如 cd /etc/aerchi/vftpuser.db)，  使用 rm  vftpuser.db  删除 vftpuser.db

[root@aerchivsftpd]# rm vftpuser.db
rm: remove regular file ‘vftpuser.db’? y

2. 使用 load_data 重新生成vftpuser.db

[root@aerchi vsftpd]# db_load -T -t hash -f /etc/aerchi/vftpuser.txt /etc/aerchi/vftpuser.db
[root@aerchi vsftpd]# ll
total 60
...
-rw-r--r-- 1 root root 12288 Sep  2 21:07 vftpuser.db
...

3. 重启ftp

service vsftpd restart

4. 再次连接， 正常。

COMMAND:>	[2020-09-02 21:21:49] CWD /*/aerchi
		    [2020-09-02 21:21:49] 250 Directory successfully changed.

		    [2020-09-02 21:21:49] 200 PORT command successful. Consider using PASV.
COMMAND:>	[2020-09-02 21:21:49] LIST -a
		    [2020-09-02 21:21:49] 150 Here comes the directory listing.
		    [2020-09-02 21:21:49] 226 Directory send OK.
STATUS:>  	[2020-09-02 21:21:49] Directory listing completed

2. FTP登录时显示: vsftpd 530 login incorrect 

查看 /etc/vsftpd/vsftpd.conf文件中的相关配置，

pam_service_name=vsftpd, 表明启用了pam.

配置:  进入  vim/etc/pam.d/vsftpd , 修改如下

#%PAM-1.0
session    optional     pam_keyinit.so    force revoke
#auth       required    pam_listfile.so item=user sense=deny file=/etc/vsftpd/f    tpusers onerr=succeed
#auth       required    pam_shells.so
#auth       include     password-auth
#account    include     password-auth
auth       required     /lib64/security/pam_userdb.so db=/etc/vsftpd/vftpuser
account    required     /lib64/security/pam_userdb.so db=/etc/vsftpd/vftpuser
session    required     pam_loginuid.so
session    include      password-auth
~

保存后, 再次重启 vsftpd. 
用 cmd 测试:

OK, 成功了

3.另, 关于 Cute FTP登录后, 远程工作区目录看不到目录列表的解决方法.

解决办法:  站点管理器右击 属性  -> 站点属性窗口, 操作选项卡, -> 筛选器 (筛选器属性)-> 取消勾选 启用筛选
