Samba and external hard disk connected by usb to the wi-fi router

FAb7D

I'm trying to use Samba (Is one of the first times)following the instructions in the Help Center for Solus KDE. I was able to share a folder without any major problems, but from here on the problems begin.
I have a hard disk attached to the modem, the disk is shared and I can see it by total commander (with SMB protocol) on an Android smartphone, but I can't see it using Solus. I digit on Delphin home->Net : smb://192.168.1..../sda1 and I get a dropped connection. I tried disabling the firewall with gufw, but the result didn't change. I tried this from terminal:
~ $ smbclient -N -L //192.168.1..../sdc1 Protocol negotiation to server 192.168.1... (for a protocol between SMB2_02 and SMB3) failed: NT_STATUS_CONNECTION_DISCONNECTED
Then I tried this:
~ $ sudo mount -t cifs "//192.168.1..../sdc1" -o guest,nosetuids,noperm,rw "samba" mount error: Server abruptly closed the connection. This can happen if the server does not support the SMB version you are trying to use. The default SMB version recently changed from SMB1 to SMB2.1 and above. Try mounting with vers=1.0. mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Do you have any suggestions?

FAb7D Do you have any suggestions?

Maybe see whether it's accessible in Dolphin when you click on Network. Dolphin uses the smb protocol to effect its connections. It works with my NAS connected to the network - maybe it will also work with a disk connected that same way.

The problem may be that your router firmware includes a (very) old version of samba that doesn't support anything but the (long) deprecated SMB V1 protocol.

The help output says you should try to mount with vers=1.0. Have you tried that?

~ $ sudo mount -t cifs "(the ip address and share)" -o guest,nosetuids,noperm,rw,vers=1.0 "samba"

I've configured the default Samba configuration on Solus to log authentication issues verbosely to files in /var/log/samba/. Maybe you will find looking at those log files useful as well?

WetGeek No, it doesn't work, thanks anyway

ermo I only changed noper to noperm and it works! Thanks!
I think that given the poor security of the protocol this (of ermo) solution with mount and umount is the best (searching on the internet I had just found trying to change samba.conf by adding

[global]
client min protocol = NT1

but it would be worse because it is generalized).
But if I'm wrong, correct me!

My modem, a BT generic model, has the USB port at the rear that can take a flash drive. As has already suggested it uses SMB1 connection and as such was removed from Windows connection options quite a while back. Some earlier Linux OSs allowed connection for a while but support was slowly dropped due to the fears of very poor security due to the use of a very outdated protocol.
Please be aware that you are downgrading the safety and security of your computer by reinstating it's usage. It was removed for a reason.
From my memory Windows 7 will still connect to SMB1 connections but I would not recommend moving to that operating system to get the feature.
Most modern media devices (smart TVs etc) will also not 'see' the connection for the same reasons so the usage of such an old protocol is very limited.
I hope this information useful to you and helps you to avoid problems further down the road.

BuzzPCSOS Yes, the problem seems to be the modem which is not that old (ASKEY RTV1907VW-D228) . So in my case it would be saffer to keep the PC turned on and share a folder via Solus which uses more recent protocols rather than using the USB port of the modem, even if it is less practical and consumes more power.

FAb7D That sounds like a plan, I tend to use a lot of external drives and USB sticks and an additional old WDCloud wireless harddrive with local network permissions only.
Another option might be to use an older computer to run as a dedicated storage server. I think there are various OSs available for this very purpose. I'm afraid that this is out of my experience but I am sure that there are plenty of users on the forum who have dabbled with that kind of setup and numerous other answers to the same issue.
All wireless storage has its limits and can be expensive. The handy USB port on a modem looks too good to be true, unfortunately it is.

FAb7D keep the PC turned on and share a folder

An alternative to leaving the PC on would be to let it hibernate. That preserves its exact status as if the machine had never been shut down, but doen't keep it running. The contents of RAM are simply stored in its swap space, and loaded from there when you start the next time.

I haven't been in your exact situation, but every machine here hibernates whenever I'm not using it. The only time it doesn't is after an update, when I need to reboot to load new packages. My experience with hibernating tells me that it would probably fix your problem.

BuzzPCSOS Yes, however I only need a file exchange point (photo, film, music, e-books) in the local network between Android and Linux devices and Fire TV Stick.

WetGeek Good idea, thanks.
