I know we're getting a littl off topic, so I'll ask first: there are a bunch of external services I use to monitor things like DNS and SMTP which are difficult to get a true handle on from the inside. Is it too off-topic to talk about some of these resources on list? (MXToolbox looks pretty interesting, I'll look into it for myself later.) --keith -- kkeller@xxxxxxxxxxxxxxxxxxxxxxxxxx _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
