Python - FileNotFoundError when dealing with DMZ

Question

I created a python script to copy files from a source folder to a destination folder, the script runs fine in my local machine.

However, when I tried to change the source to a path located in a server installed in a DMZ and the destination to a folder in a local servers I got the following error:

FileNotFoundError: [WinError 3] The system cannot find the path specified: '\reports'

And Here is the script:

import sys, os, shutil
import glob
import os.path, time

fob= open(r"C:\Log.txt","a")
dir_src = r"\reports"
dir_dst = r"C:\Dest"
dir_bkp = r"C:\Bkp"

for w in list(set(os.listdir(dir_src)) - set(os.listdir(dir_bkp))):
    if w.endswith('.nessus'):
        pathname = os.path.join(dir_src, w)
        Date_File="%s" %time.ctime(os.path.getmtime(pathname))
        print (Date_File)
        if os.path.isfile(pathname):
                        shutil.copy2(pathname, dir_dst)
                        shutil.copy2(pathname, dir_bkp)
                        fob.write("File Name:   %s" % os.path.basename(pathname))
                        fob.write("   Last modified Date:   %s" % time.ctime(os.path.getmtime(pathname)))
                        fob.write("   Copied On:   %s" % time.strftime("%c"))
                        fob.write("\n")

fob.close()
os.system("PAUSE")

what is the use of `...` (3 dots) ? – Nilesh Feb 25 '15 at 13:29 — Nilesh, Feb 25 '15 at 13:29

Okay, we first need to see what kind of remote folder you have.

If your remote folder is shared windows network folder, try mapping it as a network drive: http://windows.microsoft.com/en-us/windows/create-shortcut-map-network-drive#1TC=windows-7 Then you can just use something like Z:\reports to access your files.
If your remote folder is actually a unix server, you could use paramiko to access it and copy files from it:


import paramiko, sys, os, posixpath, re

def copyFilesFromServer(server, user, password, remotedir, localdir, filenameRegex = '*', autoTrust=True):
    # Setup ssh connection for checking directory
    sshClient = paramiko.SSHClient()
    if autoTrust:
        sshClient.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #No trust issues! (yes this could potentially be abused by someone malicious with access to the internal network)
    sshClient.connect(server,user,password)
    # Setup sftp connection for copying files
    t = paramiko.Transport((server, 22))
    t.connect(user, password)
    sftpClient = paramiko.SFTPClient.from_transport(t)
    fileList = executeCommand(sshclient,'cd {0}; ls | grep {1}'.format(remotedir, filenameRegex)).split('\n')
    #TODO: filter out empties!
    for filename in fileList:
        try:
            sftpClient.get(posixpath.join(remotedir, filename), os.path.join(localdir, filename), callback=None) #callback for showing number of bytes transferred so far
        except IOError as e:
            print 'Failed to download file <{0}> from <{1}> to <{2}>'.format(filename, remotedir, localdir)

If your remote folder is something served with the webdav protocol, I'm just as interested in an answer as you are.
If your remote folder is something else still, please explain. I have not yet found a solution that treats all equally, but I'm very interested in one.

Thank you for your help; but I didn't succeed to map the server ( Acctually I connect through WinSCP to import files manually) — mcha, Feb 25 '15 at 13:51
If you connect through WinSCP, does that mean you are connecting to a unix system? In that case I have a solution (even a code sample :D). However, it does complicate things as you'd have to make a difference between local files and remote files. — HSquirrel, Feb 25 '15 at 14:07
