一、ssh配置

给需要自动化管理的设备配置ssh服务端用户名和密码

1.FW1

#注意不要使用本地登录的用户

aaa     
manager-user user1
password cipher Huawei@123
level 15     
service-type ssh     
quit     
quit     


user-interface vty 0 4
 authentication-mode aaa
 protocol inbound all
quit

stelnet server enable   
ssh user user1
ssh user user1 authentication-type password
ssh user user1 service-type stelnet

#注意长度为2048
rsa local-key-pair create
Y
2048

2.core-sw1

aaa     

local-user huawei password cipher huawei

local-user huawei service-type ssh telnet

local-user huawei privilege level 15

quit

stelnet server enable

user-interface vty 0 4
authentication-mode aaa
protocol inbound all

quit

rsa local-key-pair create  
Y
2048

ssh user huawei authentication-type password  

ssh user huawei service-type stelnet
quit

3.core-sw2

aaa     

local-user huawei password cipher huawei

local-user huawei service-type ssh telnet

local-user huawei privilege level 15

quit

stelnet server enable

user-interface vty 0 4
authentication-mode aaa
protocol inbound all

quit

rsa local-key-pair create  
Y
2048

ssh user huawei authentication-type password  

ssh user huawei service-type stelnet
quit

二、python自动化配置防火墙

import paramiko
import getpass
import time

ip = "1.1.1.1"


username = input("Username: ")
password = getpass.getpass("Password: ")

ssh_client = paramiko.SSHClient()

#SNAT配置
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname=ip, username=username, password=password, look_for_keys=False)



print("Successfully logged in" + ip)

#配置外网地址
command = ssh_client.invoke_shell()
command.send("system-view\n")
command.send("inter gi1/0/4\n")
command.send("ip address 132.12.12.10\n")

time.sleep(0.2)
#PNAT转化地址池

command.send("nat address-group SNAT\n")
command.send("mode pat\n")
command.send("section 0 132.12.12.10\n")
command.send("route enable\n")
time.sleep(0.2)

command.send("action permit\n")
time.sleep(0.2)

#缺省路由

command.send("ip route-static 0.0.0.0 0 132.12.12.11\n")
command.send("ospf 1\n")
command.send("default-route-advertise always\n")
command.send("q\n")
time.sleep(0.2)

#DNAT转化内网地址池

time.sleep(0.2)

#允许http流量通过外网口
command.send("inter gi1/0/2\n")
command.send("service-manage http permit\n")
time.sleep(0.2)

#----------------------------------------------------------
#配置ospf路由，让监控区访问内部设备

ssh_client.close
