python怎么修改网络配置
python怎么修改网络配置?
搭建,桥接,初始化配置。
给每台路由器做好初始化配置,即配置修改设备默认名称、配置管理IP地址、配置SSH及登录用户名和密码。
以R2为例(小白,其他设备参考R2配置),修改设备名、配置IP地址:
[Huawei]SYS R2
[R2]
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.56.20 24
[R2-GigabitEthernet0/0/0]
[R2-GigabitEthernet0/0/0]qu
[R2]
以R2为例,配置SSH,其他设备参考如下即可:
[R2]rsa local-key-pair create
The key name will be: Host
% RSA keys defined for Host already exist.
Confirm to replace them? (y/n)[n]:y
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Input the bits in the modulus[default = 512]:2048
Generating keys...
.......+++
..............+++
.....++++++++
...............++++++++
[R2]user-interface vty 0 4
[R2-ui-vty0-4]authentication-mode aaa
[R2-ui-vty0-4]protocol inbound ssh
[R2]aaa
[R2-aaa]local-user along password cipher along123
[R2-aaa]local-user along privilege level 15
[R2-aaa]local-user along service-type ssh
[R2-aaa]ssh user along authentication-type password
[R2]
[R2]stelnet server enable
[R2]
上述配置完,建议用secureCRT先登录一下各个设备,验证网络连通性、ssh连通性是否ok?
这里以R1为例,验证一下。测试时,你们可以每台都验证一下。
这样验证的好处,假如待会我们写的python脚本如果有问题,那跟网络、ssh配置就没关了,便于后续排错就对啦!
