Comments? +1's? -1's? I'm basically going for ease of use among the
admins and since most people "ssh puppet1" instead of "ssh
puppet1.fedora.phx.redhat.com" I think in our diverse environment it
will be worth it and is easier then hosting a separate DNS server in
each of our locations.
I forgot to mention one other concern. A MitM attack or DNS poisoning.
This possibility does exist, but exists in our environment as is
anyway. This is something we should look at mitigating but other than
running a DNS server at every site, I'm not totally sure how to fix it.
I consider all of our donations as partnerships. After all, they have
local access to the box. At the same time though it is something we
should count as a risk and mitigate as much as possible.
As far as I can tell the only way to lower the risk of DNS poisoning
is local DNS servers. Having them getting DNS files from a central
host via a signed methodology would be not much different than
/etc/hosts except you can use other tricks and failovers
We could also implement stricter IP tables rules regarding creating
external TCP connections.
