(急)默认的ftp匿名竟然不能下载!?

Hilinux

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

我顶！

local_umask=000

Hilinux

改了！还是不行!

Hilinux

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？

汤泡饭

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。

Hilinux

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。
