Some problems with smb:// in Dolphin

English Network/Internet
#1

I am running KDE Plasma 5 in Tumbleweed and like to use smb://ip.addr in dolphin to access shares and this works fine for my NAS and Linux shares but when I use the IP address of a Windows 7 PC it says it cannot be found. I know the PC is on the lan and can ping it OK. Accessing via smbclient shows:-


smbclient -L 192.168.0.8

I can also access it via the PC’s name with smbclient with this result:-


smbclient -L STUARTS-PC

        Workgroup            Master
        ---------            -------

I have NETBIOS over TCP/IP enabled on the Windows 7 PC. I can do the abovetuart on my Leap 42.3 system and it works OK.

Also if I type smb:// on its own in dolphin it should display the workgroup and then if I click on that display associated PCs. This does NOT work on Tumbleweed but does work on Leap 42.3.

Anyone have any ideas why this is happening?

Hi
Add some debug to the output;


smbclient -d2 -L 192.168.0.8

The samba changes in TW, need to look at the vers=1.0 AFAIK, but look at the debug output to see what it’s saying

Well I ran smbclient with debug (3 not 2 as it happens)

It appears to be that it is trying to use SMB1 but I have no idea why. The windows machine has the relevant ports open and the correct workgroup set up. Access from windows to linux works. I think I’ll ignore what is happening on my 42.3 system as after an update today some of that stopped working as well, I’ll open a separate thread on that when I get this sorted.
