Bug #23352

Updated by Sven Lueder about 6 years ago

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

       end 
     end
