Yes, although, when you launch an instance, you do have the option of
selecting a zone if you want.  However, once the instance is started it
stays in that zone and does not switch.

GNU/Linux traceroute sends UDP by default. Something along the way could
be filtering UDP, so default traceroute may not be indicative.

To better replicate the problem, you can tell traceroute to send TCP
SYNs to the specific port you're trying to reach (443). Run this as root
(it needs raw sockets):

# traceroute -M tcp -p 443 dropbox.com

From other geographic locations I can connect to the dropbox service and get to 
their https web page, but from my home connection I can't, unless I vpn around 
the issue.

downforeveryoneorjustme says it's just me, but they're located someplace else

http://www.dropbox.com immediately redirects to https://www.dropbox.com

It seems like a transport issue.

Is there any tools for checking where an https connection is failing, like a

The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as 
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

Yep... While this environment would benefit greatly from deploying IPv6 on both 
sides of the connection, the reality is that NAT is easy enough and works well 
enough for the implementor that they will leave it's various pain points for 
the people that have to deal with it after implementation and they won't select 
IPv6 as a solution because it would involve slightly more pain up front.

However, the networks on both sides of these equations will have to face IPv6 
in the relatively near future anyway, unless they aren't actually talking to 
the internet in which case, it doesn't really matter what addresses or 
protocols they use.

Let it be known that I hate NAT with the burning passion of a million
suns. But I'm the junior in my workplace, and this is the advice of
the head honchos. I can easily see both sides of this. I would say
with a few implementations, (maybe 25 or fewer) NATing isn't that
difficult.

Granted we both know that NAT breaks basically everything and makes
troubleshooting a TON MORE FUN. But plenty of people out there (my
workplace included) would argue this till the cows come home.

Just because there are no plans, this doesn't mean you shouldn't bring it up.

Even if its a "radar"/"future" issue for their networking team, it does raise
the profile in the asks with others.

My workplace solves this by just NATing again. It isn't the best
solution but it does work. Put aside a 10.0.0.0/16 and whenever you
have a NATed network you want to connect a VPN to on the edge just
static NAT the addresses to make them unique again. Their 172.16.x.x
becomes your 10.2.x.x.

I dunno about 'not scalable'. I guess if your connecting to thousands
of networks it won't work well, but for a a few hundred it works well
enough.

I'm sorry you don't like it, and I know IPv6 will wash all this away
soon enough, but where I'm working we have no plans to implement IPv6,
or require our vendors/partners to readdress their networks to get a
VPN up.

Do you need to allow inbound ssh connections from the entire planet?

If not, then head over to ipdeny.com and grab the relevant network
allocations for the countries that you *do* need to allow them from.
Block everyone else, allow only the countries you need.

This won't solve your problem completely, but it'll take a substantial
bite out of it, and it'll minimize the number of additional point entries
that you need for annoying hosts whose connections originate in the
set of countries you need to allow.

Then: do you need to allow inbound ssh connections from all operating
systems?

If not, then use passive OS fingerprinting to block those which originate
from operating systems known not to be in use, particularly if those
operatng systems happen to be the ones running on a few hundred million
compromised systems.  (Obviously, this technique is far less effective
is you can't do that.  My condolences.)

And then: consider, instead of point blocks for the remaining annoyances,
use the enclosing /24.  A lot of compromised hosts are not on static
addresses, and guessing that they will bounce around inside (roughly)
a /24 is often a good enough approximation to reality that it works.
Your mileage may vary.

And then: scotch.  Macallan.  18-year.  You've earned it.

Hi,

We implemented fail2ban about a year ago to cut down on incoming 
spamming (down from 500k+ emails a day to 20k)


Now what can I do with the ~11,000 IP's I identify as spammer every 
week :(


Reporting them to their Telco is pretty much a waste of time... 
they are not about to lose customers to something as trivial as computer 
security.

In the past day, I have recorded about 20,000 unique IP addresses used for this 
type of probe.
I doubt if this is a surprise to anyone - my question is twofold:

1. Does anyone want this evergrowing list of, I assume, compromised machines?
2. Is there anything useful to do with this info other than put the IP 
addresses into a firewall reject table? I have done
   that and do see a certain amount of repeat hits.

Just a note that if you were running fail2ban.org you would get automatic 
updates of your firewall and share the IPs with the community and get the 
advantage of the communities detections as well.
