[Samba] Why is smbd listening on port 139? (using Louis' repo 4.15.7)

[Peter Milesson]

Hi folks,

I have got a samba member server Debian Bullseye 11.3 with Louis' repo 
4.15.7.

I just wanted to ask why smbd is listening on port 139/tcp?

nmbd is disabled and does not run, marked as dead when running systemctl 
status nmbd.
I have set "min server protocol = SMB2_10" and "min client protocol = 
SMB2_10" in smb.conf.
I have wsdd running for network discovery.

Everything works fine, so I'm just curious.

Best regards,

Peter
