网络批量下发配置

通过Python代码可以轻松实现网络批量化操作，相对于ansible或者其他的方式来看。Python可能是一个比较轻松实现的方式。

例如配置备份，批量配置等操作，不废话直接上代码

测试代码;

#!/usr/bin/python

#conding=utf-8

import pexpect

import os

import sys

import time

import re

ii = ['10.0.0.1',]

for host in ii:

user = 'admin'

password = 'admin'

ssh_newkey = 'Are you sure you want to continue connecting'

c = pexpect.spawn('ssh -l %s %s' % (user, host))

如果想知道整体输入和输出情况可以增加spaw里面的参数

c = pexpect.spawn('ssh -l %s %s' % (user, host),logfile=sys.stdout)

i = c.expect([pexpect.TIMEOUT, ssh_newkey, 'password: '])

if i == 0: # Timeout

pass

if i == 1: # SSH does not have the public key. Just accept it.

c.sendline('yes')

c.expect('password: ')

i = c.expect([pexpect.TIMEOUT, 'password:'])

if i == 0: # Timeout

print 'ERROR!'

print 'SSH could not login. Here is what SSH said:'

c.sendline(password)

c.sendline('\n')

time.sleep(1)

c.sendline('super')

time.sleep(0.2)

c.expect(['Password', pexpect.EOF, pexpect.TIMEOUT])

c.sendline('admin')

time.sleep(0.2)

c.sendline('display arp | in 10.0.0.') 命令根据自己需求换

c.sendline(" ")

c.sendline('quit')

c.expect(['quit', pexpect.EOF, pexpect.TIMEOUT])

print c.before

这一段是为批量执行

#!/usr/bin/python

#conding=utf-8

import pexpect

import os

import sys

import time

import re

ii = []

for number in range(17,18):

ii.append('10.0.0.' + str(number))

class sss:

def __init__(self,ii):

self.ii = ii

for self.host in self.ii:

self.user = '用户名'

self.password = '密码'

ssh_newkey = 'Are you sure you want to continue connecting'

self.c = pexpect.spawn('ssh -l %s %s' % (self.user, self.host))

self.i = self.c.expect([pexpect.TIMEOUT, ssh_newkey, 'password: '])

if self.i == 0: # Timeout

pass

if self.i == 1: # SSH does not have the public key. Just accept it.

self.c.sendline('yes')

self.c.expect('password: ')

self.i = self.c.expect([pexpect.TIMEOUT, 'password:'])

if self.i == 0: # Timeout

print 'ERROR!'

print 'SSH could not login. Here is what SSH said:'

self.c.sendline(self.password)

self.c.sendline('\n')

time.sleep(1)

注释的这几行是为了h3c这种aaa认证使用super密码的方式进行登入

# c.sendline('super')

# time.sleep(0.2)

# c.expect(['Password', pexpect.EOF, pexpect.TIMEOUT])

# c.sendline(super密码)

time.sleep(0.2)

def peizhi(self,conf):

self.c.sendline('sys')

self.c.sendline(conf)

self.c.sendline('quit')

#self.c.interact()

self.c.expect([pexpect.EOF, pexpect.TIMEOUT])

print self.c.before

def configure(self):

c.sendline('display current-configuration ' + '\n')

c.sendline(" ")

c.sendline('quit')

print c.before

c.expect([ pexpect.EOF, pexpect.TIMEOUT])

# print c.before 想看具体的可以取消这个注释

f = open(('/home/peizhi/ssh/'+host),'w')

f.write(c.before)

f.close()

ss = 'dos2unix /home/peizhi/ssh/' + host

os.system(ss)

c.sendline('quit')

conf = 'info-center loghost 172.16.3.43'

for h in ii:

try:

print h

m = sss({h:1}) 主要是为了for循环

m.peizhi(conf)

except:

print'+++++++++++++++++++++++++++++++++++++++'
