Precisely. This tells apache to do DNS lookups or not. By setting this "off" your log files will contain only IP addresses, and any CGI program called will only see IP addresses. If you set this on then apache will _for every request_ do a DNS lookup (maybe nscd will have cached it) and log the name. Reverse DNS can be slow. It's strongly recommended that web servers leave this option off. -- rgds Stephen _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
