import telnetlib
def do_telnet(Host, username, password, finish, commands):
import telnetlib
print 'hi'
'''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=2611, timeout=40)
# 输入登录用户名
## tn.read_until('login: ')
## tn.write(username + '\n')
print 'hi'
# 输入登录密码
tn.read_until('Password:')
tn.write(password + '\n')
print 'hi'
# 登录完毕后执行命令
print 'hi'
print commands
tn.write('%s\r\n' % commands)
temp = tn.read_all()
print "%r",temp
#执行完毕后，终止Telnet连接（或输入exit退出）
temp = tn.read_until(finish)
print("%r",temp)
Host = 'xxxxxxxxxxx' # Telnet服务器IP
username = 'xxxxxx' # 登录用户名
password = 'xxxxx' # 登录密码
finish = 'Router>' # 命令提示符
commands = 'help'
do_telnet(Host, username, password, finish, commands)
如上是代码，问题是，我执行到打印help之后不执行了。
