背景：利用python 的telnetlib 和paramiko库，可以实现自动化 telnet 交互，SSH交互，并可以实现文件及目录的批量上传与下载。

paramiko， 实现远程控制linux进行SSH交互

print('---------- start to create SSH object')
print('Remote SSH Info:\n\'ip:%s port:%d username:%s password:%s\'\n' %(ip_remote, port_remote, username, password))
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
ssh.connect(ip_remote, port_remote, username=username, password=password, timeout=60) # timeout protection

ssh.close()
paramiko，利用其中的sftp listdir方法，递归遍历远程服务器所有子目录及其文件，并找到目标文件（包含：feature = 'string' 的文件）下载。 由于sftp的方法太少了，不支持linux 中的‘*’通配符查找，所以只能使用递归遍历的方法了。找遍网上都没有现成的方法，所以自己写了一个：
def serachAndDownloadFeatureFile(rootPath, feature, ip_remote, port_remote, username, password):
try:
t = paramiko.Transport((ip_remote,port_remote))
t.connect(username=username,password=password)
sftp = paramiko.SFTPClient.from_transport(t)
files = sftp.listdir(rootPath)#获取到根目录下的所有目录名称+文件名字
#print('------------')
#print('current path:%s' % rootPath)
#print(files)
for name in files:
path = os.path.join(rootPath, name)
path = path.replace('\\','/')
attribute = str(sftp.stat(path))
if re.search(feature,path):
print('\nInfo: File matched !!!')
local_file_path = os.path.join(localDir, name)
local_file_path = local_file_path.replace('\\','/')
print('Downloading file from remote %s to local %s'%(path,local_file_path))
sftp.get(path,local_file_path)
else:
if attribute[0] == 'd':#是文件夹, 继续遍历
print('Start to search documents:%s'% path)
serachAndDownloadFeatureFile(path, feature, ip_remote, port_remote, username, password)
t.close()
except Exception as err:
print(err)上传的是本地的文件，故可以使用os库遍历本地目录，子目录及其文件来上传。
#上传整个目录（含全部子目录+文件）
def uploadDocuments(local_dir, remote_dir, ip_remote, port_remote, username, password):
