Hi, (Lets not get into top/bottom/mixed post discussions. :) )
I'm not sure why putting in hosts would make a difference. Doesn't the --skip-name-resolve bypass any sort of name resolution, be it /etc/hosts or resolver? Or are you telling me to change nsswitch.conf from "hosts: files dns" to just "hosts: files"? Would be a SLIM possibility, if this wasn't a machine that didn't only do MySQL and other things in my TCPWrappers (/etc/hosts.allow) did partial domain matching for clients.
