I am in the process of a fresh CUIC 8.0(3) installation.
I have properly configured the hostname, ip address, mask, gateway, domain name, NTP servers, DNS servers. I have skipped the SMTP config for later.
DNS entry was manually added to the DNS servers.
If I ping the hostname, the hostname is resolved by the DNS, and I get an echo reply.
If I ping "ping -a ip_address_of_cuic_server" (which is the reverse DNS lookup), it doesn't resolve.
The "Network Connectivity Check" is Failing with the following message:
Unable to resolve eth0 IP address into a host name (Reverse DNS lookup failed). The eth0 IP address of the DNS server may not be configured correctly. Do you wish to Retry, Review the configuration, Halt the install or Ignore the Networking error(s) and continue the Install?
I read that the SMTP uses reverse DNS lookup. Is it wise, in my case, to Ignore the Networking errors and to continue the installation?
