Question

我编写了一个简单的代码来在Cisco路由器上创建环回接口。

read_all的命令运行正常。以下是我的代码可以有人请检查并告知这里可能有什么问题：

CODE:
**********
import getpass
import telnetlib
HOST = "192.168.0.7"
user = input("Enter your username: ")
password = getpass.getpass()
tn =telnetlib.Telnet(HOST,23,1)
tn.write(b'\n')
tn.read_until(b"Username: ")
tn.write(user.encode("ASCII") + b"\n")
tn.read_until(b"Password: ")
tn.write (password.encode("ASCII") + b"\n")
tn.write(b"enable\n")
tn.read_until(b"Password: ")
tn.write(b"cisco\n")
tn.write(b"conf t\n\n")
tn.read_until(b"(config)#")
tn.write(b"int lo1179\n")
tn.write(b"exit\n")
read=tn.set_debuglevel(10000)
read=tn.read_all()
sd=open("switch", "w")
sd.write(str(read))

输出错误

telnetlib问题，read_all
