Dhcpd.conf and Subnets=> Subnet not found

Support
1

Hi guys,

Is it still needed to have all subnets you provision from Foreman into your
dhcpd.conf ?

There are various stories around about this and the docs are not clear
about it.

I thought you only needed the subnet fro the dhcp host in it so dhcpd is
able to start and foreman puhhes just to the leasesfile using omapi, but it
fails on "Subnet not Found".

What is the correct way now ?

Cheers,

Matt

Every single subnet you create in Foreman needs to be manually created
in dhcpd.conf. I recommend to turn off DHCP management in the
installer (puppet) so it won't overwrite your manually modified
configuration the next time you run it (upgrade).

Hi Lukas,

Thanks for the update, I can simply move back to the non-managed version…

What does the managed version add as value ? Is this for basic setup as the
doesn't do anything positive to the DHCP settings for other subnets in
forman.

I think this should be more clear in the puppet foreman_proxy module.

Thanks,

Matt

Adding multiple subnets support in our puppet module is long term goal
and highly requested feature, feel free to help in this area.

Hi,

That seems to be an easy task if you ask me and I can and will do when I
can test it on some test env, for now I just need the manual DHCP managed
by puppet which I hoped to cntralized to one module but I need to switch
back to the dhcp one it seems.

I was thinking about some loop on the allowed subnets, will become
allright, I have seom idea about it.

Thanks for the update!

Cheers,

Matt

Looks like I misinformed you, the puppet module does support multiple subnets:

https://forge.puppet.com/theforeman/dhcp

I think the limitation is the installer? Someone help me, I am not sure.

HI Lukas,

The dhcp module does, but when you set the puppet-foreman_proxy module
to dhcp_managed true then it doesn't. It seems you need to set that on
false and configure using the dhcp module.

I wonder what dhcp_managed to in the forman_proxy module actually does
compared to the dhcp module.

Cheers,

Matt
