**FLAGS = NetBIOS Flags (from https://www.samba.org/~ab/output/htmldocs/Samba3-HOWTO/NetworkBrowsing.html): The NetBIOS flags may be interpreted as additive hexadecimal values: 00 - Broadcast node registration, 20 - Peer node registration, 40 - Meta node registration, 60 - Hybrid node registration, 02 - Permanent name, 04 - Active name, 80 - Group name. The 'R' indicates this is a registration record. Thus 66R means: Hybrid node active and permanent NetBIOS name. These values may be found in the <code>nameserv.h</code> header file from the Samba source code repository. These are the values for the NB flags. | **FLAGS = NetBIOS Flags (from https://www.samba.org/~ab/output/htmldocs/Samba3-HOWTO/NetworkBrowsing.html): The NetBIOS flags may be interpreted as additive hexadecimal values: 00 - Broadcast node registration, 20 - Peer node registration, 40 - Meta node registration, 60 - Hybrid node registration, 02 - Permanent name, 04 - Active name, 80 - Group name.

Wait! What about the /tmp/lib/samba/wins.tdb file? According to this (even though it refers to Samba 3, it applies to Samba 4): https://www.samba.org/samba/docs/old/Samba3-HOWTO/tdb.html, the wins.tdb file is used for "permanent storage" (IE static WINS entries). Can it be edited (in a useful manner)? No, because it is a binary file, not a text file. How is information input into it? Using the NET command? We'll see. | Wait!

Ahhh! Here's the answer, with the best tip coming from this site: https://samba.samba.narkive.com/UPIyT5mM/samba-as-a-wins-server But alone that isn't enough as the static entries need to be made so they can persist across router reboots. | Ahhh!

/etc/init.d/samba4 stop | ###### There is no need to stop or start the Samba Service because the OpenWRT StartUp Script (rc.d) has a start position of 95 and the Samba4 Service has a start position of 98, so the SMB service isn't even started when this script runs. The samba4 stop and start lines were put in to emphasize this because according to Samba documentation, the samba service must be stopped to modify the wins.dat file with static entries. | ||
