Please upgrade to Smart-Proxy version 1.17, which uses a different implementation of "free ip" functionality that shared between several dhcp providers.

This should not be the only option. With version 1.16.0 all works fine. But after upgrade to version 1.16.1 the issue come up. Why is a version released, which is not working properly?

In our case an upgrade to 1.17 is not an option because we are running foreman on the host to and foreman upgrade to 1.17 fails because of not working dependencies in the debian packages. All in all it is a mess.

We'll now trying to setup a separate machine with an smart-proxy in version 1.17 to workaround this issue. While the 1.17 debian packages are fixed.

There were no changes as far as I can tell in smart-proxy. I didn't check the infoblox provider. We do not have infrastructure to test against infoblox appliance; additionally the appliance isn't used by a lot of people, so issues that you experienced will happen. Lastly, there were other issues with infoblox "unused ip" api, hence our switch to a different implementation and my suggestion.

I created a foreman proxy machine with foreman-proxy 1.17.0-1, ruby-smart-proxy-dhcp-infoblox 0.0.5 installed

This is a very old version of the infoblox provider: you'll need version 0.0.12 to be able to use 1.17 release.

Yeah we would be happy to use these version but in package repository we can only find version 0.0.5. And we prefer to install the packages which comes with your deb repo.
Is it possible to provide the newer one via deb.theforeman.org?

Please this question in #theforeman, perhaps someone will be able to help. Alternatively, please consider helping out with packaging. If all else fails, you can install the gem from sources (pls. see http://projects.theforeman.org/projects/foreman/wiki/How_to_Install_a_Smart-Proxy_Plugin for details).

After Upgrade gem to version 0.0.12 we got a error 500.

Infoblox Support is absolutly broken neither upgrade to 1.17 nor downgrade to 1.15 will work. So How can we fix this. Ipam is mission critical.

Here it helps to uninstall rack version 2.0.5 to fix the ruby error. But after that the error is still the same with the latest `gem 'smart_proxy_dhcp_infoblox', '0.0.12'`

What now?

Please check what gems are installed on your system: run gem list and then dpkg -l ruby*. In particular, please check if local and system gems contain rack: it looks like the local version of the gem overrides the system one. You may need to remove local gems (other than the infoblox provider and its immediate dependencies) to resolve this issue.

Ok, the rack error is gone as a wrote in http://projects.theforeman.org/issues/23327#note-10. But the unused_ip error is still there with the smart_proxy_dhcp_infoblox version 0.0.12 gem.

Can you post the debug-level log from the smart-proxy? The log should show the version of the infoblox gem used, is it 0.0.12, or the older one? If so, you'll need to remove the older one from the system ruby gems.

The solution to the problem is quite easy.
In smart_proxy_dhcp_infoblox/dhcp_infoblox_main.rb the function unused_ip is defined as:

def unused_ip(subnet, _, from_ip_address, to_ip_address)
unused_ips.unused_ip(subnet.network, from_ip_address, to_ip_address)
end


Because Ruby is not type-safe, the variable "subnet" is passed by Sinatra as a string without a problem, but must have been passed as an object in earlier versions (before our upgrade). Changing the function to

def unused_ip(subnet, _, from_ip_address, to_ip_address)
unused_ips.unused_ip(subnet, from_ip_address, to_ip_address)
end


What caused the problem in the first place is beyond my knowledge. Maybe you foreman guys can find the culprit.
Since dealing with unused_ip has changed in newer versions, i don't know if this "change request" is of any value.

The log you attached does't show any errors/stack traces. Could you post a snippet containing the complete stacktrace of the error you are seeing?

seems to have something to do with http://projects.theforeman.org/issues/23412

Indeed, this is exactly the same issue. I released a new version of the gem with the fix.
