Linux下pyftplib简单的脚本

from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
import os
def main():
# Instantiate a dummy authorizer for managing 'virtual' users
authorizer = DummyAuthorizer()

# Define a new user having full r/w permissions and a read-only
# anonymous user
authorizer.add_user('admin', '12345', '/root',perm='elradfmwM')
#authorizer.add_anonymous(os.getcwd())

# Instantiate FTP handler class
handler = FTPHandler
handler.authorizer = authorizer

# Define a customized banner (string returned when client connects)
handler.banner = "Simple FTPServer."

# Specify a masquerade address and the range of ports to use for
# passive connections.  Decomment in case you're behind a NAT.
#handler.masquerade_address = '151.25.42.11'
#handler.passive_ports = range(60000, 65535)

# Instantiate FTP server class and listen on 0.0.0.0:2121
address = ('192.168.3.177', 21)
server = FTPServer(address, handler)

# set a limit for connections
server.max_cons = 256
server.max_cons_per_ip = 5
# start ftp server
server.serve_forever()

if name == 'main':
main()

关于脚本的一些说明：
建立一个authorizer = DummyAuthorizer() 对象的实例
利用.add_user方法添加一个用户 authorizer.add_user('admin', '12345', '/root',perm='elradfmwM')
关于建立用户的参数的说明:
admin 用户名
'12345' 密码
/root 用户的根目录
perm='elradfmwM' 设置用户的权限

关于perm='elradfmwM' 参数介绍：
Read permissions:
- "e" = change directory (CWD command)
- "l" = list files (LIST, NLST, STAT, MLSD, MLST, SIZE, MDTM commands)
- "r" = retrieve file from the server (RETR command)

Write permissions:
 - "a" = append data to an existing file (APPE command)
 - "d" = delete file or directory (DELE, RMD commands)
 - "f" = rename file or directory (RNFR, RNTO commands)
 - "m" = create directory (MKD command)
 - "w" = store a file to the server (STOR, STOU commands)
 - "M" = change file mode (SITE CHMOD command)
