I use smb4k and it does start just fine on my TW/KDE Plasma system, there are some issues with it in that network neighbourhood does not work but that has been the case for some time. My smb4k is 3.0.6. I can mount my windows 7 system but not my NAS using smb4k because the NAS runs V1 and Linux now only supports V2 up. I am able to unmount anything with smb4k even my NAS after being mounted manually.
You are right: The symbol isn’t even shown in the system tray, but in the line of »hidden« symbols and only visible, if you click on the black triangle.
I’m very relieved. I need smb4k and synkron to sync about 50 folders from different places on a server with my notebook. Without smb4k I had to set up unison or some alternative solution, always a difficult thing, because the server runs microsoft.
Linux does still support V1, but it’s disabled by default.
It might help to set “client max protocol = NT1” in smb.conf as explained in Smb4K / Blog: Smb4K 3.0.0 released .
For mounting (which uses the kernel module that needs to be passed an additional parameter to allow v1 in current kernels), there are corresponding options in smb4k’s settings.
I can browse and mount the shares on my router (which only supports SMBv1) just fine using smb4k, after adjusting smb4k’s settings (i.e. ticking “SMB protocol version” in Mount->Advanced Mount Settings, and switching the protocol version to 1.0), even without changing smb.conf.
I’m on Leap 15.1 though, not Tumbleweed.
(but I do have samba > 4.7, 4.9.5+git.317.6d82fb3918b to be exact)
