最近小伙伴们通过启动了内网的一个FTP服务器打破了公司对公共资源的封锁，所以突然对使用启动这些服务器很感兴趣，其实说到底主要还是协议的问题。
这里用Python来实现。
首先启动HTTP服务器，这个是最简单的：
python -m SimpleHTTPServer 8080
那么接下来如何启动FTP服务器呢：
首先需要先安装pyftpdlib，接下来执行命令行就可以了。
pip install pyftpdlib
python -m pyftpdlib -p 21
此时FTP服务器也启动完成了。
如果是要做成脚本则可以这样写
import SimpleHTTPServer
import SocketServer
PORT = 8080
handler = SimpleHTTPServer.SimpleHTTPRequestHandler
httpd =SocketServer.TCPServer(("", PORT), handler)
print("serving at port", PORT)
httpd.serve_forever()
FTP服务器的启动从网上抄的
from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
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('user', '12345', '.', 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 = "pyftpdlib based ftpd ready."
# 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 = ('', 2121)
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()
