OpenWrt之自定义Hostname

找到对应的代码，在feeds/./luci/modules/luci-lua-runtime/luasrc/sys.lua中，有

        cur:foreach("dhcp", "dnsmasq",
                function(s)
                        if s.leasefile and fs.access(s.leasefile) then
                                for e in io.lines(s.leasefile) do
                                        mac, ip, name = e:match("^%d+ (%S+) (%S+) (%S+)")
                                        mac = luci.ip.checkmac(mac)
                                        if mac and ip then
                                                _add(what, mac, ip, nil, name ~= "*" and name)
                                        end
                                end
                        end
                end
        )

查看示例：

root@OpenWrt:/# cat /tmp/dhcp.leases 
1706897826 7e:56:11:9b:48:08 192.168.2.153 * 01:7e:56:11:9b:48:08

根据MAC地址反查：

local function get_name_by_(mac)
    local dft_name = "*"
    if type(mac) ~= "string" then
        return dft_name
    end

    mac = string.gsub(mac, ":", "")
    if not fs.access("/etc/config/access_client") then
        luci.util.execi("touch /etc/config/access_client")
    end

    local uci_r = uci.cursor()
    local name = uci_r:get("access_client", mac, "name")
    return type(name) == "string" and name or dft_name
end

					if mac and ip then
                        if name == "*" then
                            name = get_name_by_(mac)
                        end
						_add(what, mac, ip, nil, name ~= "*" and name)
					end

配置内容参考：

root@OpenWrt:/tmp# cat /etc/config/access_client 

config mac '7e56119b4808'
        option name 'iPhone15ProMax'
