Problem:
Want to set DHCP reservation using DHCP Smart Proxy REST Call
Example rest call:
curl -X POST https://foreman-smartproxy.example.com:8443/dhcp/192.168.1.0 --header ‘Content-Type: application/json’ -d ‘{“ip”:192.168.1.123,“mac”:00:11:22:11:22:33,“hostname”:test-dhcp-restapi.example.com}’
Expected outcome:
HTTP 200 (I guess) and the IP to be reserved on dhcp server e.g. in file /var/lib/dhcpd/dhcpd.leases:
host test-dhcp-restapi.example.com {
dynamic;
hardware ethernet 00:11:22:11:22:33;
fixed-address 192.168.1.123;
…
}
According to logs (below) it fails during ip address validation:
/usr/share/foreman-proxy/lib/proxy/validations.rb:17:in `validate_ip’
I checked the relevant code that validates the ip address
16 def validate_ip ip
17 raise Error, "Invalid IP Address #{ip}" unless ip =~ /(\d{1,3}\.){3}\d{1,3}/
18 ip
19 end
and I made sure, that the IP I used validates ok like this:
ruby -e ‘puts “invalid” unless “192.168.1.123” =~ /(\d{1,3}.){3}\d{1,3}/’
Since the IP isnt logged (see log below) it means, that IP is somehow lost during the request.
Foreman and Proxy versions:
both: 1.19.1
Foreman and Proxy plugin versions:
just enabled dhcp module by:
:enabled: https
:use_provider: dhcp_isc
