备份交换机文件到tftp服务器,使用Python批量备份Cisco和H3C交换机配置到TFTP服务器...

我的代码如下，已经转为python3格式：

#!/usr/bin/python3

# -*- coding: utf-8 -*-

now = datetime.datetime.now()

def main():

for host in open(“sw.txt”, “r”).readlines():

dsthost = host.strip(‘\n’)

try:

tn = telnetlib.Telnet(dsthost, port=23, timeout=15)

tn.read_until(“Username:”)

tn.write(user + “\n”)

except:

print(“Can’t connection %s” % dsthost)

continue

try:

tn.read_until(“Password:”)

tn.write(password + “\n”)

result = tn.read_some()
