    SSHClient

    用于连接远程服务器并执行基本命令

    1、SSH登陆到交换机执行指令,并且将结果反馈到file1

    import paramiko

    # 创建SSH对象
    ssh = paramiko.SSHClient()
    # 允许连接不在know_hosts文件中的主机
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    # 连接服务器
    ssh.connect(hostname='IP', port=22, username='admin', password='123')
      
    # 执行命令
    stdin, stdout, stderr = ssh.exec_command('display interface brief')
    # 获取命令结果
    result = stdout.read()
    f = open("file1","wb")
    f.write(result)
    f.close()
    ssh.close()
    # 关闭连接
    ssh.close()
     
     
    另外一种方法,有登陆日志,不错
     
    # -*- coding: utf-8 -*-
    import paramiko

    def sshclient_execmd(hostname, port, username, password, execmd):
    paramiko.util.log_to_file("paramiko.log")

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    ssh.connect(hostname=hostname, port=port, username=username, password=password)
    stdin, stdout, stderr = ssh.exec_command(execmd)
    stdin.write("Y") # Generally speaking, the first connection, need a simple interaction.
    a = stdout.read()
    file = open("log","wb")
    file.write(a)
    file.close()
    ssh.close()

    def main():
    hostname = ''
    port = 22
    username = ''
    password = ''
    execmd = "display ip interface brief"
    sshclient_execmd(hostname, port, username, password, execmd)
