Looks like redhat-config-date may also have to figure out the appropriate netmask for the "restrict" line from the list of IP addresses that the name resolves to. Please see bug #70557 for an explanation of why we use the IP address on the server line instead of the hostname. If my understanding is correct, redhat-config-date does a DNS lookup on the entered hostname since hostnames may be spoofed. I don't quite understand the reasoning, considering that IP spoofing is also possible. On a purely rhetorical note, why not enter the Hardware addresses instead of the IP addresses? Hostnames are supposed to provide a layer of abstraction over IP addresses, and as such are commonly used for purposes such as load balancing. Resolving breaks such applications. I'm not reopening the bug, as I'm not entirely sure if entering hostnames is necessarily a good thing either. |
