突然感觉好无奈，这个咋整？ 让其先行一步

[station]

试过多次就差那么几秒 , 蛋好疼....

[imn1]

本来想回复让你自己按摩一下的，进来居然看到标题改了～

dhcp比dnsmasq还慢？

[whatot]

After=network.target

我的dnsmasq.service有这么一条，不知道你的为什么是这样??

[whatot]

添加一个依赖，应该就行了

[station]

@whatot 你这么一说，我查看了下更蛋疼

[station]

@imn1 从时间上看貌似是的

[whatot]

@station 你试试让dnsmasq在dhcp之后启动。。。。

[Starduster]

写个脚本在开机之后 xx 秒再一遍跑 dnsmasq

[realpg]

改一下dnsmasq的init.d脚本 增加检测wlan0的IP 如果检测不到就sleep5

[station]

@realp 发行版本fedora,程序中没有...

[station]

@Starduster 总觉得这不是根本解决之道，肯定那里出问题了，亦或是bug ?

[station]

@whatot dhclient ?

[station]

@whatot 真是日了狗

[whatot]

@station 因为我用的是桌面系统，所以使用的是NetworkManager，NetworkManager管理了这一系列的启动，跟你的有点区别。但肯定的是dnsmasq启动太早了。

[station]

@whatot 的确，好多after=network.target都比network启动早，我还找不到原因，实在不行只能重做系统了......

[HMSQQbA]

systemd真是蛋痛的玩意，常出此类问题。

[station]

@HMSQQbA 你也遇到了？ 感觉bug一样

[HMSQQbA]

@station 不是你这个问题，但常遇到各种unit不能按规则触发。对systemd总体感觉不好。

debian 8 的dnsmasq.service：
[Unit]
Description=dnsmasq - A lightweight DHCP and caching DNS server
Requires=network.target

[Service]
Type=forking
PIDFile=/var/run/dnsmasq/dnsmasq.pid

# Test the config file and refuse starting if it is not valid.
ExecStartPre=/usr/sbin/dnsmasq --test

# We run dnsmasq via the /etc/init.d/dnsmasq script which acts as a
# wrapper picking up extra configuration files and then execs dnsmasq
# itself, when called with the "systemd-exec" function.
ExecStart=/etc/init.d/dnsmasq systemd-exec

# The systemd-*-resolvconf functions configure (and deconfigure)
# resolvconf to work with the dnsmasq DNS server. They're called liek
# this to get correct error handling (ie don't start-resolvconf if the
# dnsmasq daemon fails to start.
ExecStartPost=/etc/init.d/dnsmasq systemd-start-resolvconf

ExecReload=/bin/kill -HUP $MAINPID

@rwzsycwan service文件其实没什么差别 fedora 21 但没有/etc/init.d/dnsmasq这个文件
