@weidongyan Please run sudo systemctl status dnsmasq and post output here. As well I may ask you to post the full content of your dnsmasq configuration file.

@Sebastian-Roth I was having trouble with starting dnsmasq service, saying bad dhcp-range which pointed to the end of the configuration was something wrong. I tried to reinstall dnsmasq service and now it is working now. I am not sure if there is some connection between these two problem.

Please check your config again. All the places where you have <192.168.88.40> should actually be 192.168.88.40 without the tag characters!!

+1 That’s exactly the problem.

There is another tutorial on how to install dnsmasq service here: https://forums.fogproject.org/topic/12796/installing-dnsmasq-on-your-fog-server

@george1421 Hi, George. Unfortunately, I still got the same problem here with that issue fixed. My configuration is like this

@george1421 Hi George, it worked!!! After I made update for dnsmasq. I was thinking about that dnsmasq did not use the configuration that I created to run. So I was updating it and it worked. Thank you.

[george1421]

@weidongyan And you have confirmed that dnsmasq is running on the fog server ps aux|grep dnsmasq AND the pxe booting client are on the same subnet?

[weidongyan]

@Sebastian-Roth Thank you Sebastian. I got it worked. Thank you so much for your patient help. I really appreciate.

@george1421 I got some tricky ways to find if dnsmasq is using the configuration that we created. In the directory /etc/dnsmasq.d/, we created the configuration file, but if there is no other file called README, I think dnsmasq did not use the configuration file. But after I updated dnsmasq, there is a new file called README. And it works!!! I am not sure if my thoughts was right. But it got working in my case.
