Host name resolving problem for Mac

[pomelo]

Hi there,
I need help for setting up lan-mouse running on two of my mac devices: an Intel MBP 2014 (macOS 12.7.6) and an M1 Pro MBP (macOS 15.1).
I found lan-mouse couldn't resolve the hostname that ends with .lan or .local. If I don't provide the hostname in the configuration files but use ips list, it works. The only problem is both of them are running with DHCP client, so I have to change the IP list from time to time.

The toml file is as below:

# configure release bind
release_bind = [ "KeyA", "KeyS", "KeyD", "KeyF" ]
# port = 4242

# optional frontend -> defaults to gtk if available
# possible values are "cli" and "gtk" 
frontend = "cli"

# hostname
hostname = "W-Silicon.local"
activate_on_startup = true
ips = ["192.168.1.211"]

And the logs are:

I recall that using the .local TLD is discouraged on MacOS because it is used for mDNS.
See https://en.wikipedia.org/wiki/.local or https://superuser.com/questions/1828456/macos-cannot-access-custom-local-domain.

With .lan I don't know why that should be a problem though. Could you verify that the .lan domains actually cause problems as well?

[pomelo]

@feschber Thanks for the replying. The problem is, I can't modify the .local suffix, it is grayed out in the Settings, and if I set W-Silicon.lan for local hostname, then it says 'The Bonjour Name is invalid.' and won't save the changes.

And you are correct, the .lan domain is working, so that I can move the cursor from the Apple Silicon MBP to the old Intel MBP. However, soon after I typed a few letters, the client mac (old intel one) got repeatedly key stroke, and even ctrl-d / ctrl-c wouldn't work to terminate the lan-mouse process, and I can only kill it from Activity Monitor. I thought it was a release bind problem, so I commented it out but the problem was not resolved.

Here are the logs:

I have a similar problem. The '.local. is what Bonjour normally uses but even setting the correct hostname lan-mouse doesn't seem able to resolve while dig can... It seems like lan-mouse only wants to connect to an IPv6?
