Samba – nmb Won’t Announce Samba Shares

networkingsambasamba4windows

I'm using samba on Fedora Server Edition. But I can't figure out why any windows can not see it. It can connect (directly, using ip address). It basically works, but I can't see them on either linux (using nautilus) nor windows explorer.

Basics:

  • OS: Fedora Server Edition 32
  • hostname: bienenstock.local
  • samba: 4.12.5-0.fc32.x64_64
  • firewall is running (samba is allowed – I'm able to connect directly)
  • SELinux is enforcing (reading/writing on shares works fine)

## and some others, but for sake of length of this writing I reduced the length

As you can see, both daemons are up and running (thou I do not understand why a "domain master name query" fails … – might be relevant?).

Sadly looking up the internet only reveals problems related to samba, SELinux, etc. But this works, the only thing that does not is announcing it on windows explorer or nautilus. What am I missing?

Thank you in advance!

You have SMBv1 turned off (as it should be, it is very insecure) and SMBv1 is required for Network Browsing. Try installing this: https://github.com/christgau/wsdd It will allow your Windows clients to see your Samba machine using Network Discovery.

You might want to read 'man smb.conf', you have quite a few lines you don't need and don't have a line you do need ;-)
