五、FAQ<br>
Q：在本地ftp localhost输入用户名、密码回车后。等很久才进入FTP Server<br>
A：ftp 127.0.0.1<br>
<br>
Q：在远程服务器上ftp ip输入用户名、密码回车后。等很久才进入FTP Server<br>
A：LDAPServer localhost 改为 LDAPServer 127.0.0.1<br>
<br>
Q：[root@linux mod_ldap-2.8.10]# ftp 127.0.0.1<br>
Connected to 127.0.0.1 (127.0.0.1).<br>
500 FTP server shut down (going down at Tue Dec 17 19:00:00 2002) -- please try again later.<br>
ftp><br>
A：rm –rf /etc/shutmsg<br>
Q：登录Ftp Server 提示<br>
530 Login incorrect.<br>
Login failed.<br>
我确认输入的用户、密码决对正确<br>
A：在登录ProFTPD时加参数proftpd –d5 –n会输出调试信息。你可以在其中<br>
找到答案。如果在调试信息中找到这一行no such user 'xxxx'<br>
可能是与MySQL/OpenLDAP连接有问题。<br>
Q：我在网上看见很多介绍如何安装ProFTPD文章,阅读大量的How to，按How to一步一步做，从来没有安装成功过。<br>
A：网上很多文章，比较老，很多定义现以不在使用如：<br>
