paramiko远程操作示例二

本机通过堡垒机(192.168.2.201)向目标主机(192.168.2.202)上传文件test.c
__author__ = 'silence0607'

import paramiko,sys

localpath = '/home/nick/c/test.c'
remotepath = '/tmp/test.c'
passinfo = '\'s password: '


if __name__ =='__main__':
    t = paramiko.Transport(('192.168.2.201',22))
    t.connect(username = 'root',password = 'silence')
    sftp = paramiko.SFTPClient.from_transport(t)
    sftp.put(localpath,remotepath)
    sftp.close()

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(hostname = '192.168.2.201',username = 'root',password = 'silence')
    channel = ssh.invoke_shell()
    channel.settimeout(10)

    buff = ''
    resp = ''
    channel.send('scp /tmp/test.c root@192.168.2.202:/mnt'+'\n')
    while not buff.endswith(passinfo):
        try:
            resp = channel.recv(9999)
        except Exception,e:
            print 'Error info:%s connection time.'%(str(e))
            channel.close()
            ssh.close()
            sys.exit()
        buff += resp
        if not buff.find('yes/no') == -1:
            channel.send('yes\n')
            buff = ''


    channel.send('silence'+'\n')


    buff = ''
    while not buff.endswith('# '):
        resp = channel.recv(9999)

            print 'Error info: Authentication failed.'
            channel.close()

            sys.exit()


        buff += resp
    print buff
    channel.close()
    ssh.close()
运行结果如下：
