proftp 1.2.8rc2 问题求助？

我 使用的是proftp 1.2.8rc2
我的配置文件如下

1. # This is a basic ProFTPD configuration file (rename it to
   
2. # 'proftpd.conf' for actual use.  It establishes a single server
   
3. # and a single anonymous login.  It assumes that you have a user/group
   
4. # "nobody" and "ftp" for normal operation and anon.
   
5. 
   
6. ServerName                        "ProFTPD Default Installation"
   
7. ServerType                        standalone
   
8. DefaultServer                        on
   
9. #Port 21 is the standard FTP port.
   
10. Port                                21
    
11. 
    
12. # Umask 022 is a good standard umask to prevent new dirs and files
    
13. # from being group and world writable.
    
14. Umask                                022
    
15. 
    
16. # To prevent DoS attacks, set the maximum number of child processes
    
17. # to 30.  If you need to allow more than 30 concurrent connections
    
18. # at once, simply increase this value.  Note that this ONLY works
    
19. # in standalone mode, in inetd mode you should use an inetd server
    
20. # that allows you to limit maximum number of processes per service
    
21. # (such as xinetd).
    
22. MaxInstances                        30
    
23. 
    
24. # Set the user and group under which the server will run.
    
25. User                                nobody
    
26. Group                                nobody

29. 
    
30. UseReverseDNS                   off

32. <Directory />

34. </Directory>
    
35.

37. <Anonymous /home/ftp>
    
38.   User                                ftp       
    
39.   Group                                ftp
    
40. 
    
41. # We want clients to be able to login with "anonymous" as well as "ftp"
    
42. UserAlias                        anonymous ftp
    
43. RequireValidShell               off
    
44.

当我用anonymous登录时候显示Login failed
当我运行了passive命令后
显示ftp:bind:address already in use
会不会跟我使用两个网卡有关呢？

刚才参看 /var/log/secure文件
看到如下几行

1. Jun 13 23:50:57 eryk proftpd[2875]: eryk (127.0.0.1[127.0.0.1]) - USER ftp (Login failed): User in /etc/ftpusers
   
2. Jun 13 23:57:30 eryk proftpd[2880]: eryk (127.0.0.1[127.0.0.1]) - USER ftp (Login failed): User in /etc/ftpusers
   
3. Jun 14 00:02:43 eryk proftpd[2929]: eryk (127.0.0.1[127.0.0.1]) - USER ftp (Login failed): User in /etc/ftpusers
   

复制代码

于是猜想是不是anonymous映射的ftp用户在/etc/ftpusers文件中存在呢，结果删除ftp后一切正常。
后来在proftpd 1.2.8-rc2的faq里面搜索ftpusers
找到如下几行，相信是什么意思大家应该看的懂

1. UseFtpUsers
   
2. Name
   
3. UseFtpUsers -- Block based on /etc/ftpusers
   
4. Synopsis
   
5. 
   
6. UseFtpUsers [ UseFtpUsers on|off]
   
7. 
   
8. Default
   
9. 
   
10.     UseFtpUsers on
    
11. 
    
12. Context
    
13. 
    
14.     server config, <Anonymous>, <VirtualHost>, <Global>
    
15. 
    
16. Module
    
17. 
    
18.     mod_auth
    
19. 
    
20. Compatibility
    
21. 
    
22.     0.99.0 and later
    
23. 
    
24. Description
    
25. 
    
26. Legacy FTP servers generally check a special authorization file (typically /etc/ftpusers) when a client attempts to authenticate. If the user's name is found in this file, FTP access is denied. For compatibility sake, proftpd defaults to checking this file during authentication. This behavior can be suppressed using the UseFtpUsers configuration directive.

哎~~~~~~~~~~希望给后来人提个醒。

倒
怎么会把ftp这个用户莫名奇妙的加到/etc/ftpusers里面去呢

jeoncanon

我也不是很清楚
可能装完系统就是这样的了
关于useradd groupadd这些我都没有修改过
