From c8aa7b152f423cc2147afbb8b9245f056103d1f7 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sun, 22 Feb 2026 14:15:20 +0100 Subject: [PATCH] network: enable LLDP for links that use only link-local addressing Links with link-local-only communication are typically peer-to-peer links between two laptops or similar. In such cases it makes sense to be able to see which device one is specifically connected to, hence let's just enable LLDP for it. This doesn't leak any data really, given that this is inherently local, and typically only used between isolated systems that are under the same user's possession. Background: I recently connected multiple laptops via thunderbolt networking and was kinda annoyed not being able to see what system I was actually talking to. (Also, the file touched here is an example only anyway, so even if this would leak too much info, it's not in effect by default) --- network/80-auto-link-local.network.example | 2 ++ 1 file changed, 2 insertions(+) diff --git a/network/80-auto-link-local.network.example b/network/80-auto-link-local.network.example index 286b532496..5af0c62782 100644 --- a/network/80-auto-link-local.network.example +++ b/network/80-auto-link-local.network.example @@ -18,3 +18,5 @@ Property=ID_NET_AUTO_LINK_LOCAL_ONLY=1 LinkLocalAddressing=yes IPv6AcceptRA=no MulticastDNS=yes +LLDP=yes +EmitLLDP=yes
