Hi All,
I am experiencing occasional hangs on an FC4 web server that is
also a name server. After rebooting the only thing I see in the logs
are about a zillion messages from named stating "RCODE (SERVFAIL)".
Here is an example:
Jul 14 02:03:37 www named[1652]: unexpected RCODE (SERVFAIL) resolving
'52.134.78.140.in-addr.arpa/PTR/IN': 140.78.2.62#53
These messages go on for about 15-18 minutes and then the system hangs.
I'm assuming it's some type of hacking attempt.
Can anyone give me some insight on what might be happening here and better
yet how to prevent it?
Thanks,
Mike
