comment Cisco Catalyst 3550 Switch - VLAN ACL question
@HampusLi - I should have known that, as I've got a 3550 floating around somewhere in my datacenter, even though it's only doing L2.

comment How do you search for backdoors from the previous IT person?
another +1 for adding the, what some would consider obvious, idea that making sure your outgoing admin isn't psychotically pissed off at you may be allow you to save the business potentially millions of dollars in consultants.

comment Postfix open relay
are you wanting a remote user to be able to "bounce" mail thru your server or do you want your server to accept and locally deliver mail with any @destination? You might take a look at this: serverfault.com/questions/164105/… to see if it's what you're wanting.

comment How do I set up failover for a single web server using two ISPs?
actually, the OP's original problem is more one of asynchronous routing than the DNS response. While I've never actually asked, I'd have to imagine that most cable/DSL providers will balk at sending out BGP advertisements for a home connection.

comment I need a server or service that reroutes DNS requests
I do run multiple DNS servers, actually multiple clustered DNS servers behind a hardware load balancer, and a hidden master. But, this would work just as well, if with less reliable uptime, with a single server. I would be more than happy to either post the files here or bundle them up and email if it would be useful.

comment How do I setup Bind9 on ubuntu as a nameserver?
glad to be of help...just to clarify for the populace at large, if this were an internal only DNS server, all you would have to do is make sure your internal clients were pointed at the server. But, for a publicly facing server, your registrar has to point to your server(s)
