Hi,
when running
nncp-daemon -bind 192.168.2.23:1234
I do get
2025-12-01T23:07:50Z ERROR MCD on lo/5400/1234: write udp
[::]:1234->[ff02::4e4e:4350%lo]:5400: sendto: network is unreachable
How can I turn MCD off? Shouldn't it, for reasons of security, used
only when explicetely turned on?
regards
Hadmut

... it, btw., does print that error message every 10 seconds, thus
flooding log files.

I think you can just comment out the mcd lines in the config, or tighten
up their patterns.
I don't think there is a security risk since any peer has to
authenticate itself and be known to your NNCP already.
What OS are you on? It sounds like lo isn't an Ethernet interface and
probably shouldn't be used.
