使用 Paramiko 从 Juniper 获取 o/p 时,输出首先显示命令,然后执行命令。下面是代码和输出
import paramiko
import getpass
password = getpass.getpass()
with open('ips.txt','r') as f:
ip = f.read().splitlines()
for device in ip:
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(device, port=22, username='test', password=password, look_for_keys=False, allow_agent=False)
remote_connection = ssh_client.invoke_shell()
remote_connection.send('set cli screen-length 500\n')
remote_connection.send('ping 4.2.2.2 rapid\n')
import time
time.sleep(3)
output = remote_connection.recv(4096)
print(output.decode())
with open('Backup.txt', 'a+') as f:
f.write(output)
f.write("\n********************\n")
ssh_client.close()
输出如下:
