问题！我发现Pure-ftpd有个重大bug，该怎么办？？？

daocaoyida

我用的最新版的pure-ftpd-1.0.21

既然是ftp服务器那肯定要支持上传对吧？

上传那就要支持断点续传吧？

那好，在/pure-ftpd.conf的配置中有如下这个配置

# Allow users to resume and upload files, but *NOT* to delete them.

KeepAllFiles               yes

如果把这个注释掉和改成no效果是一样的，那就是可以删除文件，也可以续传文件

但如果改成yes的话，不可以删除，可以续传，但问题出来的，竟然可以覆盖掉原文件，也就是说可以用1KB的文件覆盖掉几GB的文件

注：我已经在pure-ftpd.conf设置了不能改名与删除文件


下面把配置贴出来大家看看就知道，不知这么严重的问题是我设置有问题还是这个软件的大bug~~

# Be 'customer proof' : workaround against common customer mistakes like
# 'chmod 0 public_html', that are valid, but that could cause ignorant
# customers to lock their files, and then keep your technical support busy

# knowledge, this feature is useless. If you're a hosting service, enable it.

# Per-user concurrency limits. It will only work if the FTP server has
# been compiled with --with-peruserlimits (and this is the case on
# most binary distributions) .
# The format is : <max sessions per user>:<max anonymous sessions>
# For instance, 3:20 means that the same authenticated user can have 3 active
# sessions max. And there are 20 anonymous sessions max.

# PerUserLimits            3:20



# When a file is uploaded and there is already a previous version of the file
# with the same name, the old file will neither get removed nor truncated.
# Upload will take place in a temporary file and once the upload is complete,
# the switch to the new version will be atomic. For instance, when a large PHP
# script is being uploaded, the web server will still serve the old version and
# immediatly switch to the new one as soon as the full file will have been
# transfered. This option is incompatible with virtual quotas.

# NoTruncate               yes


# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.

# TLS                      1

# Listen only to IPv4 addresses in standalone mode (ie. disable IPv6)
# By default, both IPv4 and IPv6 are enabled.

# IPV4Only                 yes


# Listen only to IPv6 addresses in standalone mode (ie. disable IPv4)
# By default, both IPv4 and IPv6 are enabled.

# UTF-8 support for file names (RFC 2640)
# Define charset of the server filesystem and optionnally the default charset
# for remote clients if they don't use UTF-8.
# Works only if pure-ftpd has been compiled with --with-rfc2640

# FileSystemCharset        big5
# ClientCharset                big5

还有个问题想问一下，
pure-ftpd要怎样设置总带宽？而不是设置每个用户都是同样的速度，

我想要上传者的速度大点要怎么实现呢？谢谢！！
