Foreman » Smart Proxy

I am using Foreman Proxy to register DNS entries using the API.

Issue:
When trying to register a reverse DNS entry (PTR record) I do receive the following error:
Invalid reverse DNS 51.50.168.192.in-addr.arpa.

Solution:
Looking into the code i see that the trailing dots in PTR FQDNs are not permitted, although they should.

The following patch will solve the issue:

  cd /usr/share/foreman-proxy/modules/dns
  patch -p0 dns_api.rb << '@EOF'
