Question

是否可以通过Paramiko登录和注销远程/ SSH会话，并在每次登录/登录时执行不同的命令？

我能够SSH到路由器并执行命令，但是事实证明，我可以在单个会话中多次运行该命令；但是，我想在每次执行命令时登录并注销

def run_ssh_command(username, password, ip_add):
    """
    Using paramiko to SSH into remote locations and run commands
    """
    port = 22
    remote_connection = paramiko.SSHClient()
    remote_connection.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    host = ["192.168.122.164", "192.168.122.228"]

    for ip_add in host:

        while True:

            try:
                remote_connection.connect(ip_add, port, username, password, look_for_keys=False, timeout=5.0)
            except paramiko.SSHException:
                print('SSH error')
                remote_connection.close()
            except paramiko.AuthenticationException:
                print('Authentication failed')
                remote_connection.close()
            except socket.timeout:
                print('Socket timeout')
                remote_connection.close()
            except socket.error:
                print('Socket error')

            stdin, stdout, stderr = remote_connection.exec_command("show ip bgp summary")
            output = stdout.readlines()  # prints output in list format
            iterator = range(len(output))

            while True:

                for i in iterator:
                    if 'Idle' in output[i].split() or 'Active' in output[i].split():
                        print('BGP not reconverged')
                        break
                else:
                    print('BGP OK')
                    break
            break

if __name__ == '__main__':

    while True:
        run_ssh_command("julls", "cisco", "ip_add")
        break

理想情况下，我想在遇到“ BGP未重新融合”时立即爆发；建立另一个会话，检查“ BGP OK”是否正确，如果注销，然后执行另一个“ remote_connection.exec_command”-在这种情况下，我将发出“重新加载”之类的信息，而不是“ show ip bgp summary”。 paramiko可以做到这一点吗，还是我需要一个单独的模块？

使用paramiko运行多个命令
