[Kea-users] config-hash-get – uses full config to hash?

“Using the same config that I have loaded in the server” do you mean the config file in /etc/kea? If so, can you use the write-config API to get the configuration in memory and compare it again?

Hi all,

I was exploring using the `config-hash-get` command to get a hash of the loaded config and then compare with a candidate config to see if anything was change before loading.

Using the same config that I have loaded in the server, I couldn’t get a hash that matched the one we get via the `config-hash-get` command.

Is that something in the way I’m generating the hash? I’m passing the entire dhcp4 config (ie. {"Dhcp4":…}) to the hash function.

I also noticed that if I do a `config-get` command, the output will contain every optional field that is usually not present in a manually generated config. Could that be the reason why the hashes don’t match?

Thanks,
– Diogo
