将telnet和ftp的下载上传封装成函数：

#encoding=utf-8

def do_telnet(Host, username, password, finish, commands):
import telnetlib
'''Telnet远程登录：Windows客户端连接Linux服务器'''

# 连接Telnet服务器
tn = telnetlib.Telnet(Host, port=23, timeout=10)
tn.set_debuglevel(1)

# 输入登录用户名
tn.read_until('login: ')
tn.write(username + '\n')

# 输入登录密码
tn.read_until('assword: ')
tn.write(password + '\n')

# 登录完毕后执行命令
tn.read_until(finish)
for command in commands:
tn.write('%s\n' % command)

#执行完毕后，终止Telnet连接（或输入exit退出）
tn.read_until(finish)
tn.close() # tn.write('exit\n')

def do_ftp_download(host,username,password,localfile,remotefile):
import ftplib

'''connect the remote linux server'''
ftp=ftplib.FTP()
ftp.connect(host,port=21)
#ftp.set_debuglevel(2)

''' longin '''
ftp.login(username,password)
ftp.set_pasv(0)

f = open(localfile, 'wb')
ftp.retrbinary('RETR ' + remotefile, f.write, 1024)
f.close()
ftp.close()

def do_ftp_upload(host,username,password,localfile,remotefile):
import ftplib

ftp=ftplib.FTP(host)
ftp.login(username,password)
#ftp.set_debuglevel(2)
f = open(localfile, 'rb')
ftp.storbinary('STOR ' + remotefile,f)
ftp.close()
f.close()

begin_time=int(time.time())
