(急)默认的ftp匿名竟然不能下载!?

Question

os:FC3 vsftp没有改变应该可以匿名访问下载.但是现在下载时出现"复制文件时发生错误"的对话框!有没有兄弟遇到过同样的错误呢?在线等!

我的vsftp文件是:

1. # Example config file /etc/vsftpd/vsftpd.conf
2. #
3. # The default compiled in settings are fairly paranoid. This sample file
4. # loosens things up a bit, to make the ftp daemon more usable.
5. # Please see vsftpd.conf.5 for all compiled in defaults.
6. #
7. # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
8. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
9. # capabilities.
10. #
11. # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
12. anonymous_enable=YES
13. #
14. # Uncomment this to allow local users to log in.
15. local_enable=YES
16. #

18. write_enable=YES
19. #
20. # Default umask for local users is 077. You may wish to change this to 022,
21. # if your users expect that (022 is used by most other ftpd's)
22. local_umask=022
23. #
24. # Uncomment this to allow the anonymous FTP user to upload files. This only
25. # has an effect if the above global write enable is activated. Also, you will
26. # obviously need to create a directory writable by the FTP user.
27. #anon_upload_enable=YES
28. #
29. # Uncomment this if you want the anonymous FTP user to be able to create
30. # new directories.

34. # go into a certain directory.

40. # Make sure PORT transfer connections originate from port 20 (ftp-data).
41. connect_from_port_20=YES
42. #
43. # If you want, you can arrange for uploaded anonymous files to be owned by
44. # a different user. Note! Using "root" for uploaded files is not
45. # recommended!

63. # ftp server can use as a totally isolated and unprivileged user.
64. #nopriv_user=ftpsecure
65. #
66. # Enable this and the server will recognise asynchronous ABOR requests. Not
67. # recommended for security (the code is non-trivial). Not enabling it,

69. #async_abor_enable=YES
70. #
71. # By default the server will pretend to allow ASCII mode but in fact ignore
72. # the request. Turn on the below options to have the server actually do ASCII
73. # mangling on files when in ASCII mode.
74. # Beware that turning on ascii_download_enable enables malicious remote parties
75. # to consume your I/O resources, by issuing the command "SIZE /big/file" in
76. # ASCII mode.
77. # These ASCII options are split into upload and download because you may wish
78. # to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),

84. # You may fully customise the login banner string:

100. # You may activate the "-R" option to the builtin ls. This is disabled by

102. # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

Answer 1

我顶！

Answer 2

local_umask=000

Answer 3

改了！还是不行!

Answer 4

通过大量的试验，原来能否下载还与被下载的文件的权限有关。
1 通过匿名上传上去的文件的权限是700
2 我试验时在pub目录中创建的文本文件也是700
这样都下载不了！现在无法下载的问题找到了，可是改怎么解决呢？
是说用local_unmask=022吗？这个掩码是干吗的，是对pub文件的权限的掩码吗？

Answer 5

文件的主人如果是ftp的就应应该能下载，其它人的文件应该给上R权限吧。

Answer 6

呵呵，汤泡饭说的不错！问题解决了，就是因为是匿名上传的文件，所以其其权限是640！因此只能上传而上传的文件不能下载！现在我加了一行
anon_umask=022解决了这个问题！还得感谢ftp版的wolfg.

可能其他兄弟很少会遇到这个问题，主要是我给不同的网段的人不同的权限，使局域网中的用户可以自由上传下载。

呵呵，兄弟总结一下，也post到ftp版吧。
