Host name resolving problem for Mac
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"
[left]
# 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?
@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?

Having this problem atm. Anyone find a solution or workaround? I can't seem to find a way to change the .local on my macbook. Nor an option to change it from my router.
I can't seem to find a way to change the .local on my macbook.
I normally use .lan (for the reasons @feschber mentioned) but actually it seemed to revert to .local today (maybe a recent macOS update forced it?)
Anyway, I ran sudo scutil --set HostName whirlyjig.lan (replace whirlyjig with your hostname) and it changed the output of hostname correctly.
#!/bin/bash set -e
HOST_NAME="omarchy.local" CONFIG_PATH="/tmp/lan-mouse-server.toml" PORT=4242 echo "🔍 正在解析 $HOST_NAME 的 IP..."
用 ping -c1 方式快速解析 mDNS（只发 1 个包，1 秒超时）
SERVER_IP=$(ping -c1 -t1 "$HOST_NAME" 2>/dev/null | grep -oE '([0-9]+.[0-9]+.[0-9]+.[0-9]+)' | tr -d '()')
if [ -z "$SERVER_IP" ]; then echo "❌ 无法解析 $HOST_NAME，请检查 Linux 端是否开启 mDNS（avahi-daemon）。" exit 1 fi
echo "✅ 对方 IP: $SERVER_IP"
