winbind using wrong netbios service code in queries

For the past day, I have been trying unsuccessfully to let my Ubuntu VM be able to resolve NetBIOS names on the local network, to find some non-computer devices (Printers, special barcode machines, etc..) that don't have a fixed IP. At first, I assumed I am failing to configure the usage of winbind/wins for resolving, even though I had read every webpage that ever mentioned nsswitch.conf, and I was sure my configuration should be correct. running nmblookup printername returns a successful result that looks like: x.x.x.x printername And this was my first clue, the service type. I fired up wireshark, and tried to ping printername, and I saw a NetBIOS broadcast asking for printername, to which no one replied. I stopped the winbindd service, and run it manually in foreground using: sudo winbindd -F -S -d 10 then tried the same ping, and I saw winbindd attempting the same erroneous query with instead of . Why is this happening? Where can this be configured? EDIT: Closing this question as this is hardcoded in the source. Digging through the code, I found the function in winbindd_wins_byname.c, harcoded as such: `subreq = resolve_wins_send(state, ev, state->request->data.winsreq, 0x20);`
