四、proftpd配置文件解析

# This is a basic ProFTPD configuration file (rename it to

# 'proftpd.conf' for actual use.  It establishes a single server

# and a single anonymous login.  It assumes that you have a user/group

# "nobody" and "ftp" for normal operation and anon.



ServerName            "ProFTPD Default Installation"

ServerType            standalone

DefaultServer            on

# from being group and world writable.

Umask    022        #新文件的权限掩码



# 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            30



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

User                nobody
