I've a shared folder created (with access to everyone) in Windows. on C:\sharedfolder, so I can access it with:

\\mylocalnetworkip\sharedfolder

Now I want a Python script to write stuff there from another machine.

If I run this simple script on Windows (from my machine, using Python under Windows), it works. It creates the file and writes that content.

file = open(r'\\mylocalnetworkip\sharedfolder\tester.dat', 'w')
file.write('whatever')
file.close()

But if I run the same script in Linux (from another machine, but still on my local network, this means if I ping my IP it works), it doesn't work.

With it doesn't work I mean that it doesn't fail, the strange thing that it creates a file on the same path with the name of the entire 

root@mc:/tmp# python tester.py  <-- the script with the code above
root@mc:/tmp# ls
\\mylocalnetworkip\sharedfolder\tester.dat  tester.py
root@mc:/tmp# cat \\mylocalnetworkip\sharedfolder\tester.dat
whatever
root@mc:/tmp#

Can someone give me a hand and tell me how can I make it work in Linux? Thank you!

PS: I also tested it using '\\\\mylocalnetworkip\\sharedfolder\\tester.dat' with no luck.

  • Can you please show us the output of root@mc:/tmp# ls \\mylocalnetworkip\sharedfolder. I think you must mount the shared folder first. Commented Jun 14, 2019 at 14:31

    You have the cat on the code I provided. Its content is the whatever string, the thing you want to write. Commented Jun 14, 2019 at 14:32
  • Sorry my mistake. I edited my first comment and added the ls. You have to "mount" the shared folder first into your linux filesystem. You can not access it before. Commented Jun 14, 2019 at 14:34

    Are you sure I need to mount it before accessing it? This is because I'm using Linux? Why works directly from Windows? I tried to access a remote folder using Windows (not the one of my machine) and works too. Commented Jun 14, 2019 at 14:39

Two problems here.

Mounting

Linux is not able to handle paths like this \\mylocalnetworkip\sharedfolder\tester.dat.

On a Linux system you first have to "mount" a shared folder before you can use it. After mountig (depending on the mount point) the path could look like this /mnt/mylocalnetworkip/sharedfolder/tester.dat.

There are different ways to mount on Linux. e.g. check out https://unix.stackexchange.com/q/18925/136851 or https://www.putorius.net/mount-windows-share-linux.html

Path separators

Windows and Linux using different path separators. A fine solution in Python is to create a path like this.

import os
os.path.join('/', 'mnt', 'mylocalnetworkip', 'sharedfolder', 'tester.dat')

The result is

/mnt/mylocalnetworkip/sharedfolder/tester.dat

Be aware of the first / which indicates the root of the linux filesystem.

This doesn't work for network folders
