如何实现Linux FTP服务不区分大小写？

如何快速、有效解决这个问题呢？

2) 官网http://www.castaglia.org/proftpd/下载最新mod case模块（proftpd-mod-case-0.7.tar.gz），并本地解压提取mod_case.c文件

3) 上传proftpd（proftpd-1.3.6.tar.gz）安装包至网管服务器

4) 解压proftpd安装包至当前目录

#tar -zxvf proftpd-1.3.6.tar.gz

5) 上传mod_case.c文件模块至proftpd-1.3.6/contrib目录

6) 编译并安装proftpd服务

#cd proftpd-1.3.6

#./configure --prefix=/usr/local/proftpd --sysconfdir=/etc/proftpd --with-modules=mod_case

#make

#make install

7) 编辑 /etc/proftpd/proftpd.conf，按照如下蓝色标注修改内容：

注意：以下MaxClients是新添加内容。

# To prevent DoS attacks, set the maximum number of child processes

# to 30.  If you need to allow more than 30 concurrent connections

# at once, simply increase this value.  Note that this ONLY works

# in standalone mode, in inetd mode you should use an inetd server

# that allows you to limit maximum number of processes per service

# (such as xinetd).

MaxInstances   150

MaxClients    100

# Set the user and group under which the server will run.

User    root

Group   root

8) 编辑 /etc/proftpd/proftpd.conf，添加如下蓝色标注添加内容：

ServerName                      "ProFTPD Default Installation"

ServerType                          standalone

DefaultServer                      on

# Enable case-insensitivity for all FTP commands handled by mod_case

CaseEngine on

CaseIgnore RETR

RootLogin on

# Port 21 is the standard FTP port.

Port                            21

9) 将附件proftpd（随机启动脚本）上传至/etc/rc.d/init.d目录

10) 关闭操作系统其它FTP服务（service vsftpd stop/chkconfig vsftpd off）

11) 设置proftpd随机启动

#chmod +x /etc/rc.d/init.d/proftpd

#chkconfig --add proftpd

#chkconfig proftpd on

12) 重启机器

#init 6
