hi

I'm really struggling for over a week to try and connect to my external SMB hard drive. It's on my routers samba server. It's really straight forward for other devices both Android cellphone and iPad Pro, they have zero problem, they detect and connect instantly to the external SMB hard drives.
But using various SMB clients , Krusader, Dolphin browser etc,... they just dont detect it ... when I do put in the IP address, most the time I get "connection to host is broken"
I've checked samba services and all seems to be working properly.
I'm thinking maybe Dolphin etc is searching the wrong port? I'm using port 445.
Also have disabled UFW firewall to make sure its not that that's blocking it.

Running Kubunto, 20.04
Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
Kernel Version: 5.4.0-42-generic
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-2630QM CPU @ 2.00GHz
Memory: 7,7 GiB of RAM

Any one else have this issue and got a fix solution, please?

TIA

I don't use samba but I've seen similar threads that point to a fairly recent change in systemd that made SMBv2 default and disable SMBv1. If this is your problem you must re-enable SMBv1.

Also, Dolphin is a layer on top of the SMB service so it won't be the problem - if you connect without Dolphin you'll have the same problem, and maybe get a more useful error message.

Hi there, thanks for response.
Yes I saw similar and what I did was enabled it in the smb.conf file (or at least I believe I did) by adding "client protocol = NT1" as well as trying variations of it, but no change in the problem seemed to happen. (btw NT1 is supposed to be used for SMB1, I'm told).
The odd thing is, being new to linux, I tried an Ubuntu 20.04 before just to see what it was like and oddly I got it to work, it was detected through Krusader and then Dolphin ... I dont know what is different now to then.

I do know that the router SMB external harddrive server is definitely SMB1, but as I said my iPad Pro as well as Android phone still finds it.
Is there any way to downgrade the linux SAMBA version?
And I'm wondering if the updated Dolphin, Krusader etc still support SMB1?

Ps .. I also wonder if Linux is actually searching port 445 and not another ... my SMB is on port 445
