Question

您好我使用pySMB模块在python中遇到错误。

在为自己制作脚本时，我遇到了尝试连接到网络共享的麻烦。这是Python代码

 from smb.SMBConnection import SMBConnection

 server_name = 'Server'
 client_name = 'My Computer'
 s = SMBConnection('guest', '', client_name, server_name, use_ntlm_v2 = True)
 s.connect('192.168.1.35', 139)

 print s.listShares()

所以如果从Windows计算机运行此脚本，它可以与Linux服务器或Windows服务器一起使用。我得到的错误是当我在linux中运行脚本试图连接到Windows服务器的共享时。 Wireshark Capture

这是Python中的错误

出了什么问题，我该如何解决？

Answer 1

我不太确定 server_name 的值与 192.168.1.35 相匹配。但它是 SMBConnection 的重要参数，所以我以另一种方式提供变量，而不是以纯文本形式提供，这是我的：

from nmb.NetBIOS import NetBIOS

def getBIOSName(remote_smb_ip, timeout=30):
    try:
        bios = NetBIOS()
        srv_name = bios.queryIPForName(remote_smb_ip, timeout=timeout)
    except:
        print >> sys.stderr, "Looking up timeout, check remote_smb_ip again!!"
    finally:
        bios.close()
        return srv_name

Answer 2

以下代码适用于python3，用于从Windows共享文件夹中读取文件。我使用pysmb_sample和content of file来创建此代码。我在Ubuntu 15.10，python 3.4上测试它，同时从Windows服务器接收共享文件夹中的文件，它工作正常。

import  urllib.request 
from smb.SMBHandler import SMBHandler

director = urllib.request.build_opener(SMBHandler)
fh = director.open('smb://username:password@IP_address/shareFolder/shareSubfolder/fileName')
print(fh.read())
fh.close()

pySMB Windows文件共享缓冲区溢出
