====== Static WINS Entries (not to be confused with LMHOSTS File) ====== | |||
First things first: The LMHOSTS file is used ''only'' the local computer / server (IE, the OpenWRT / LinkSys device that is acting as the WINS / NMBD (The component of Samba that equates to WINS) Server). The LMHOSTS File and its entries are ''not'' used in resolving names to IP Addresses for clients of the WINS Server. That duty is held by two files: wins.dat and browse.dat. And no one seems to want anyone to find those files (IE, I dare anyone to find documentation, besides here that notes the location of both of these files. | |||
/tmp/lib/samba/wins.dat (AKA /var/lib/samba/wins.dat) | |||
/tmp/cache/samba/browse.dat (AKA /var/cache/samba/browse.dat) | |||
Here's an interesting statement about the wins.dat file from https://wiki.rockstable.it/Samba: "On Samba the dynamically maintained database is stored persistently across reboots in <code>/var/lib/samba/wins.dat</code>, which is written in regular intervals." Keep in mind this was not written about OpenWRT. Does that make a difference? Yes it does. Look at the path OpenWRT stores the wins.dat file (Hint: It begins with /tmp, which means it does ''not'' persist across reboots). Is this compensated for with something in the /etc/init.d/samba4 configuration file? Nope. In the /etc/config/samba4 settings? Nope. Solution? Make one up. | |||
In OpenWRT, is it possible to put manual entries in the /var/lib/samba/wins.dat file? Yes. Will the entry exist for more than about 30 seconds? No. So putting static entries into the wins.dat file is pointless. That's for the NMBD Service which responds to broadcast requests for a NetBIOS name. | |||
The format of entries in the /var/lib/samba/wins.dat file are from here: https://www.linuxtopia.org/online_books/network_administration_guides/samba_reference_guide/17_NetworkBrowsing_23.html | |||
* "NAME#TYPE" TTL ADDRESS+ FLAGS | |||
** NAME = NetBIOS name | |||
** TYPE = NetBIOS type | |||
** TTL = Time To Live (in seconds) | |||
** ADDRESS+ = One, possibly more addresses for the Computer / Entity | |||
** FLAGS = NetBIOS | |||
