Dear Maintainer,

I've sometimes been able to get Windows devices to interoperate with Debian 
devices knowing
each other by thir hostnames on the local link using NetBIOS or Avahi/Bonjour. 
However,
on some Windows 7 devices, even after adding several permissive rules to the 
firewall
and installing Bonjour, some client software is not able to resolve ".LOCAL" 
names.
Examination with Wireshark suggests Windows is sending out LLMNR requests.  It 
would
be nice for interoperabilty if Debian hosts could by default respond to LLMNR 
for their 
own hostname.

Upstream 'avahi' has an old ticket for such a possible feature...

http://avahi.org/ticket/125

There's also an independent SourceForge project 'xllmnrd' to provide LLMNR 
responder
by itself...

https://sourceforge.net/projects/xllmnrd/

(Note also yet another SourceForge project 'zcnr' "LLMNR implentation for 
Linux" which
has released no code)

LLMNR is defined in RFC 4795.

It's not enabled by default, but if you switch your system (I think 
on bookworm or newer) to systemd-resolved and either NetworkManager 
or systemd-networkd, you will get LLMNR support.
