Redhat 8.0 - DDNS problem
 

Hello,

I am looking for the help after 1 week of uselles work. I have troubless with setting of ddns on redhat 8.0. I have set named.conf and dhcpd.conf including interim mode and although I may to lease the ip address, it is not registered in dns. I have the "dhcpd: if IN A hostname domain dosn't exist add hostname "key": connection refused.

I really don't know what next to do with that message.

Please help !!!!!!!!!!!!!!!!!

Thank you in advance.
