Fog Setup with Exsiting DHCP Server onsite with no Bootp

[TechWiz]

Hi @Sebastian-Roth

Thanks in Advance for your assistance

My Config

Clean install Ubunthu 16.04 lts with latest updates
Fog v 1.5.5

I need to deploy Images on sites with soho routers that can provide dhcp only no bootp features

What will your ideal fog config with dnsmasq look like to be able to function in environments like this.

Regards

@TechWiz make sure you are using dnsmasq 2.76 or later dnsmasq -v

Yes correct. The error we see in the picture shows that you have an older dnsmasq version which appends .0 to the end of the filename. Maybe update to Ubuntu 18.04 or set a link: ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.kpxe.0

I will test both options

Thanks for your support

I have done ln -s /var/lib/tftpboot/undionly.kpxe /var/lib/tftpboot/undionly.kpxe.0

Testing now…

[TechWiz]

Will Update shortly

/var/lib/tftpboot/

Why /var/lib/tftpboot/??? FOG changes the config to point to /tftpboot!! Did you modify the path in the config by hand?

@TechWiz What version of dnsmaq is installed? Use this command from the linux command prompt sudo dnsmasq -v It needs to be version 2.76 or later.

Also if you use dnsmaq then you need to disable isc-dhcp server if you had FOG installer enable it.

Hi George

I am installing a clean ubuntu 18.04 lts now with latest update, the fog 1.5.5 will disbale or select no for fog dncp option is that correct with you sir?

[george1421]

@TechWiz You don’t need to reinstall the entire system if you did select to install isc-dhcp server. You would simply just tell the service to stop and then update the .fogsettings file so the next time you run the installer it doesn’t enable it again for you.

But to answer your question, correct answer NO to install dhcp server option. Then install dnsmasq using the quick start guide I provided.

@george1421

Can I use your config just as is just change the ip address, regards

@TechWiz Yes should be fine. Just give it a try and see what you get.

Hi George

I need assistance to setup dnsmasq in ubuntu 18

[Sebastian Roth]

@TechWiz How should we possibly help you if you don’t tell us where exactly you are stuck and need help with.

[george1421]

@TechWiz Did you get dnsmasq installed? If so just save my config file in /etc/dnsmasq.d as ltsp.conf. Be sure to update the ltsp.conf file with the IP address of your fog server. Once that is done start dnsmasq using sudo systemctl start dnsmasq and then sudo systemctl enable dnsmasq to start the service at each reboot. Confirm that its running by issuing the following command ps aux|grep dnsmasq. It should show you that dnsmasq is running in memory. sudo systemctl status dnsmasq will also do that for you , but the output is a bit verbos.
