[SOLVED] Connecting to windows server shared folder under active directory

[wago80]

Hi, all!
I am trying to connect to a windows server shared folder from my Kubuntu 20.04 LTS.

In my home (a 192.168.X.X LAN) I can access shared folders from a windows 10 laptop and the winodws 10 can access the shared folders in my kubuntu, so it works both ways

Here in my work, I try to access a shared folder from a windows server from dolphin writing smb://<server_ip>/shared_folder_name and I get a Timeout from server mesage.

From a windows 7 (which is joined to the windows domain) I can access the shared folder without problems using \\<server_ip>\shared_folder_name in the windows explorer route bar.

The shared folder in the windows server is shared to "All" but not to "Anyone", so I guess the problem I getting is related to some autentication. I guess the windows server doesnt allow the kubuntu to access because is not a domain memeber.

There is any way to access this shared folder from my kubuntu?

Thank you all in advance.

Pay attention to the part about /etc/win-credentials

Generally, it's better to trouble-shoot mounting a samba connection from the command line first - to make sure there's nothing in the way, Then attempt using Dolphin. Dolphin can be a bit problematic directly accessing samba shares sometime.

I believe that I tried that exact link, but I will check it again in case I missed something...

Thanks! =)

I checked that but I cant access either.

I am now focus in access through terminal first and then by GUI.

I try several "smbclient" commands and in all of them I get "protocol negotiation failed: NT_STATUS_IO_TIMEOUT"

some of the commands I try were:

smbclient -L '\\10.XX.XX.XX\'
smbclient -L \\\\110.XX.XX.XX
smbclient -L \\\\110.XX.XX.XX\\
smbclient -L //10.XX.XX.XX
smbclient -L //10.XX.XX.XX/
smbclient -L //10.XX.XX.XX/sharedfolder -U domain_name/username
smbclient //10.XX.XX.XX/sharedfolder -U username=domain_name/username
smbclient \\\\10.XX.XX.XX\\sharedfolder -U username%userpassword
smbclient //10.XX.XX.XX/sharedfolder -U username%userpassword
smbclient \\\\10.XX.XX.XX\\sharedfolder -U domain_name/username%userpassword
smbclient //10.XX.XX.XX/sharedfolder -U domain_name/username%userpassword

Thank you for your help

Try adding this to the Global section of smb.conf:

client min protocol = NT1

Thank you, thank you, thank you, thank you, thank you! =)
I could connect! I couldn't be happier! =)

Great. That was easy. The clue was in the error message: "protocol negotiation failed: NT_STATUS_IO_TIMEOUT"

This simply says the default NT protocol was mismatched - as in the server didn't match the client. Most OSs do not allow NT1 by default anymore as it's unsafe.

Ok, great! Thanks for the info!

I will ask you another question: now I can access the shared network files only by Dolphin but not from Gimp for example, so I am trying to mount that shared folder to a folder in my home, with this command:

sudo mount -t cifs -o credentials=/home/username/credencials //<ip_server>/ /home/username/sahredfoldername

where credencials is a text file which has this:

username=myusername
password=mypassword
domain=domainname

and I get this error:

mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

But the route is ok since I copy it to dolphin and can access without problem.

Any idea?

Thanks!

For Gimp to have access to external folders may depend on which sort of package it was installed from. Snaps and Flatpaks only have access to local home directories by default, but this can be changed.
So this may still be an issue after you mount the share.


Does /home/username/sahredfoldername exist already? You do need to create the directory if you haven't already done so.

I really dont remember how I installed GIMP. I guess it was by Snaps, but Im not sure.
Could you tell me what should I change in order to grant GIMP access to remote folders?

Yes, the folder exist.

Thanks!

either your mount point is missing, or incorrect (typo?), or the path to the credentials file is. or maybe the server address? In any case, the "No such file or directory" indicates something of this nature.

Not sure if Discover's Snap interface has GUI options for this in 20.04 or not, but check and see if you have this:
