运行我从stackoverflow下载的以下脚本登录到连接到控制台服务器的Cisco交换机,并发出“sh run”命令。
#!usr/bin/python
import getpass
import telnetlib
HOST = "10.252.128.81:3132"
user = input("Enter your username: ")
password = getpass.getpass()
tn = telnetlib.Telnet(HOST)
tn.read_until("login: ")
tn.write(user + "\n")
if password:
tn.read_until("Password: ")
tn.write(password + "\n")
tn.write("show run\n")
tn.write("exit\n")
print(tn.read_all())
Python新手,所以当我运行脚本时,我得到以下输出。
Enter your username: user1
Warning: Password input may be echoed.
Password: cisco123
Traceback (most recent call last):
File "D:\Users\ted\workspace\Test\cisco.py", line 10, in <module>
tn = telnetlib.Telnet(HOST)

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):

有什么想法吗?

不严格回答您的问题,但根据您的目标可能有所帮助。 我正在使用PrettyGoodTerminal来编写Cisco路由器的脚本,因为它管理我的连接,Python部分更多的是关于发送命令和处理结果。对于一个简单的“sh run”你也不需要Pytonh,但看起来像这样:
result = Terminal.ExecCommand("sh run","#")
commandResult = result[0]
timedOut = result[1]
if not timedOut:
ActionResult = commanResult
ScriptSuccess = True
