ssh连接方式

# coding=utf-8
 
import paramiko,sys,time
 
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
#连接SSH服务器
client.connect("192.168.10.1",22,"admin","admin")
#执行命令的方式一   连接linux发送固定指令
stdin,stdout,stderr = client.exec_command("whoami")

stdin,stdout,stderr = client.exec_command("ls")
print(stdout.read())
stdin,stdout,stderr = client.exec_command("ls -la")
print(stdout.read())
 
#执行命令的方式二  获取命令行参数，并且删除参数1.保留需要执行的命令
buf = sys.argv
del buf[0]
str1 = ' '.join(buf)
print(str1)
#执行命令行参数给出的命令
stdin,stdout,stderr = client.exec_command(str1)
